Plastics in the recycling process: from waste to waste.
The very first and important stage of the recycling process is sorting waste at home. But what happens later?
Where does the waste end up and how does a PET bottle transform into a fleece sweatshirt?
Let’s follow through the most important process in our trade: the recycling cycle of plastics.
First of all, it’s worth noting that not all plastic is the same! The term “plastics” covers hundreds or maybe even thousands of different synthetic polymers, composite materials and many mixes of plastic, which have been produced and continuously improved for about 100 years now.
Bin lorries collect our rubbish, which then, depending on the fraction, is sent to proper waste-sorting plants or municipal establishments. In order to reprocess and recover materials, they have to be thoroughly sorted, which means there is the second-level sorting process of plastics.
Sorting plant is a place where machines and human workers separate waste. Plastic is divided into PET, HDPE, PVC and many more fractions. At this stage we eliminate highly soiled elements that could disrupt the next processes.
We are going to sort PETs, let’s begin!
The conveyor belt (sorting line) is made up of different sorters, including the optical ones. Thanks to their advanced technology which uses X-ray or infrared radiation, the sorters can detect wave spectrum of waste, classify it and properly separate it. Another type of sorters are special sieves with eyelets of specific diameters – sometimes very small elements are not recyclable, therefore they have to be eliminated. Weight sorters react to high weight of certain elements, because they are programmed to know how much a PET packaging of specific dimensions weighs. Too light or too heavy elements do not go to the next stages.
However advanced the machines are, they might make error and need human oversight. People also work along the conveyor belt, between the sorters and at the end of the line. Their reliable eyes detect details even the most up-to-date machines couldn’t eliminate.
When the waste arrives at the recycling facility, it is firstly separated into two groups: municipal and industrial. If the recovered raw material is going to be used for consumer purposes (e.g. packaging, textiles), we process waste from the same, primal source. If it’s going to be used in the automotive industry and for example, become a car battery’s case, then it can be sourced from industrial waste.
We are moving on to the loudest stage, which is shredding and crushing. Now we need crushers, fast-spinning blades and other machines suitable for specific recyclable materials. PETs are relatively hard, but easily breakable, so they end up in the crushers. Rubber, on the other hand, is very ductile and flexible. If it landed in a crusher, it would behave like a chewing gum in your mouth. It wouldn’t crush and crumble, so it has to go to the cutting chamber. The whole scheme is to grind it in the most optimised and efficient way.
Now let’s go back to our PET – after crushing and pressing, we get small elements, irregular in diameter of around 1 cm.
Shredding is important for two reasons:
Firstly, not all sorting plants or recycling facilities are equipped with all essential conveyors, sorters and machines that enable full processing from waste to recyclate. Sometimes the recycling process is divided between more facilities. It’s cheaper and more efficient to transport shredded materials than full-size waste.
Secondly, even if the recycling operation takes place in one place, it’s easier to process fragments than full-sized packaging, which we will explain in the next part of the text.
Collected waste can sometimes carry substantial marks of wear and tear. The most soiled elements are eliminated at the first stage of sorting.
Now it’s time to get rid of the labels, dust and dirt. All unwanted elements are “blown out” in a special air-chamber. Lighter elements of dirt are separated from heavier PET flakes.
Now that the air cleaned our materials, let’s give them a proper bath.
The cleaning stage is not only about eliminating dirt. It has a second important function: final waste sorting. All plastics have specific rates of density. Our PET should float on the water surface. If some elements fall on the bottom, it means there is pollution that is heavier than PET. We don’t want it in the next stages of the process, so we eliminate it.
Drying and autoignition
Clean materials are dried, which is not that easy as it may seem. All sorting plants and recycling facilities are in danger of spontaneous ignition (combustion) of plastic. It may be caused by overheating at the stage of drying, uncontrolled build-up of gases, electrifying of the plastic fragments or too much dust in the air.
The knowledge about possible dangers can help implement suitable precautions and preventive measures at all stages of the processing.
If our material is clean, dry and we are 100% sure it’s free of all contaminants, we divide it according to its colour. It’s a task dedicated exclusively to a special optical sorter. It measures waves of colours and sorts it – with the highest precision.
Final recyclate – extrusion
The last stage of the recycling process is melting the plastic in the extruder. The plastic pellets are placed in the machine. Inside, they are heated and liquified. Next, the plastic is forced into moulds, where it cools and hardens. The solidified material is then extruded in the form of long strands. It can be coiled or cut into smaller pieces. It depends on the extruder’s technology and the recyclate’s final destination.
Finished recyclates are sent to factories. The material is used in 100% in new products or is added to virgin plastic. And so we stand a chance of seeing our old plastic on a store shelf. We can take it home, use its hidden treasure and later put the empty packaging in the proper waste bin!
The above description is of course a simplified picture of the plastics recycling, but it’s enough to understand that it’s a technologically complex and multi-stage process.
We should be aware that everything starts at our homes and we are the ones who can make the recyclers’ job a lot easier by properly sorting our waste. Not only household, but also processing plant owners should know they are responsible for the first step of the recycling process.
Black color is believed to be elegant, but also neutral and practical. A closure in this color can be easily matched with other colors of bottles or labels, achieving a perfect combination.
Detergent themselves aren’t associated with environment protection, but rather lead to negative associations with chemical substances which end up in sewage, and adversely affect water flora and fauna.
Fortunately, in fact in most Polish cities our home or factory sewage undergoes a long and complex purification process as part of which it’s filtered at many stages, and, to the greatest possible extent, restored a condition in which it can
Looking at innovative solutions, we need to anticipate their consequences.
Biopackaging or so-called eco-friendly packaging sells great, and may become the core of the product’s or brand’s entire marketing campaign. The question is, whether with the current knowledge and the ability to look ahead, this behavior is justified from the environmental point of view.
Will the balance of profits and losses be positive, and if so, for whom?
We can assume that the world is crazy about environment protection. What would be more correct to say, however, is that the world was crazy when it didn’t think about it at all.
We live in the period in which we already know that our thoughtless attitude to littering the Earth must come to an end.
Following trends, and even setting new ones, we try to surprise our clients with new products every now and then!
This year, those who visited us during the Cosmoprof trade fair in Bologna were impressed by the new products on our offer.
If Bologna always welcomes guests in such a way, we want to be there more often!
Protective packaging, because we will be talking about it, doesn’t have good reputation as a medium for advertising functions. However, the sales value of the protective film can’t be overestimated.
Not only transparent ones!
Not only for nail varnish removers!
It, therefore, means that you are responsible for what you’ve created or what you have put on the market. From the very beginning until the very end.
When our neighbors need help, we devote all our power and energy to provide it!
The trade show is a celebration for the industry!
It’s the place where clients meet their suppliers, competitors meet each other and, most importantly, potential suppliers meet potential clients.
Our offer is rich in products that are used in cosmetics or household detergents.
However, there are such nooks and crannies in our catalog that only a few look into, and maybe it's time to show off a pump with a really BIG DOSAGE to a wider audience!
Mini triggers are among the most interesting closures in our offer.
This solution is, in a way, a link between the cosmetic and detergent offer of our products. Mini triggers can be perfect closures of both home, and beauty products.
For a long time now we have been on a kind of crusade for plastic, emphasizing its advantages and appreciating its unrivaled physical and chemical properties compared to other materials. Sometimes we felt like the devil's advocate, but the more research was conducted, the more studies were published, the bigger sense we saw in our work.
We’re aproach new year!
We're entering it with hope and a strange request that is unlike its last two predecessors.
In late December, Pantone Institute announced a very energetic purple, with the graceful name Very Peri, to be the color of 2022. The symbolism behind it, given by the authors, involves self-reflection, curiosity and a bold look into the future.
And the latter, despite all adversities, is what all of us need mos
Our "regular distribution", that is ready-made products available in our Warsaw warehouse, is an answer to our Clients’ needs. We closely watch their interest and orders, and on that basis make decisions on introducing products to the list of “immediately available” ones.
Trend research focuses not only on the preferences of younger age groups who are growing up to enter the market as consumers, but also analyzes the behavior of those already present on it.
The ‘Silver tsunami’ is the beautiful name for the 55+ age group, which for some time now has been a colorful sociological and market phenomenon.
Modesty is our second name, just after reliability!
Today, our reliability has been appreciated, so we have to overcome modesty and loudly as well as proudly say:
We are one of the “Forbes’ Diamonds 2022” winners!
Our trade fair autumn is slowly coming to an end, so you will have an opportunity to meet us one more time in the final of that tour, during WarsawPack in Nadarzyn (23 – 25 November).
That stand will feature our both departments – the production of packaging lines and ours, i.e. closures for packaging and cosmetic packaging.
Until recently the list of packaging functions seemed to be complete. The packaging and its closure were supposed to tightly secure the product against a leakage, dispense it in the most comfortable and secure way, as well as fulfill marketing functions.
We offer different thickness and width of the polyolefin heat shrink film and what comes with it is a wide range of its possible uses. Polyolefin is one of the most environmentally friendly plastics as it is a polymer made up of carbon and hydrogen which makes for an ideal material recovery. Some claim that the aesthetic and end result are what matters the most.
We are really pleased that we had an opportunity to see our regular clients in a good shape and, first of all, in good health.
It was a great pleasure to us that the stand was visited by representatives of companies we hadn’t had a chance to cooperate with.
Does every element need to distinctly emphasize the brand, or is it worth unifying the packaging and, sticking to minimalism, focus on the identification expressed by the printed inscription on the label?
We are happy that after the two-tear break caused by the pandemics we can participate in trade fairs again.
We are really looking forward to meeting our Clients and potential Clients, as direct conversations at our stand are really important to us. Although recently we have often seen each other online, we believe that getting back to classic face-to-face meeting is crucial. Casual conversations at the stand are not only an oppo
The Quality Control Department is one of the most important places in our company. Thanks to the processes, examinations and tests that take place there, our clients get efficient, failure-free, pretty and clean products.
What must happen, however, for them to be deemed such?
Recently, we have been forced to again raise the prices of our products.
We feel obliged to explain the reason for these changes.
In the recent two years, so from the moment of the pandemic outbreak, the costs of transport of a container on intercontinental routes have increased eight times.
Mist sprayers, as a majority of elements of packaging have to play several roles. They should mostly be functional and adjusted to the medium.
Lately there have been wide discussions that if we don’t save our planet, our next generations won’t be able to use its resources. Climate change is a fact and nobody can argue with it, but we still talk about the methods to care for the Earth without further harm.
The very first product that comes to our minds when we think of a trigger sprayer is of course a window cleaner. It is used in households, offices and other public service places. Lately, the store shelves have been stocked with more and more different products closed in trigger sprayers.
Purchase decision are made by consumers as young as 3 or 4 years old! They are the main target groups of the online or TV ads played during the cartoons. Kids are also more susceptible to the store displays or creative points of sale.
Nowadays customers become more and more eco-conscious. People read and analyse the product composition and are aware of the materials used for packaging. Many shopping choices are made based on their eco-friendliness.
More than ever before, the last year truly proved the fact that we live in a global village. Every country, almost every business owner, and finally every man, depend on other people and random events. We always knew it in theory, but now we have found it to our cost.
Hair obsession, which is a conscious hair care, has recently become more and more popular and gained many female followers.
Plastic recycling has been widely discussed for a long time now, but the topic has not been exhausted yet and there is a lot more to cover
Polpak Sp. z o.o. joined the elite circle of companies awarded with the Business Gazelle title!
Does the outbreak of the pandemic relieve the businesses from the eco-responsibilities?
In the first part of our eco-design series we covered its main principles and explained why it is important to stick to it through all stages of the product development. We already know how to choose a bottle. Now we will discuss the remaining packaging elements along with their eco-versions.
Eco-design is yet another newly coined term that has recently entered our dictionaries. Its etymology is self-explanatory, but what does it really mean? What requirements have to be met in order to call a product’s design “eco”?
Yellow and grey have been crowned the colours of 2021. The choice is not random: it reflects the lifestyle and mood prevailing in the current situation.
We are closing 2020 with record sales – in the second part of December we hit 100 million sold products!
In the first part we discussed some of the problems our traders have to deal with on a daily basis. We put it forward to share the knowledge and show you that some solutions must make not only for the visual effect, but firstly for the better functionality of the packaging with the specific medium and bottle.
From time to time we lift the veil of secrecy surrounding our company’s internal affairs. We write about our cool team of well-tuned members who love their jobs. This year we shared a few honest thoughts on our business branch which suffered many turmoils and swirls.
The history of the breakthrough inventions shows that scientists from different places researched a phenomenon or worked on a specific project at the same time, and then announced their revolutionary findings virtually simultaneously.
Since the Polpak Packaging department now also offers polyolefin shrink film (also called shrink wrap), we are able to not only deliver perfect packaging closures and complete cosmetic packaging, but also become the next chain in securing our Customers’ products.
The ever-growing amount of plastic contributes to its ever-worsening opinion.
Most of our world contains polymer elements and most of the eco-media coverage presents it in a negative light.
We, on the other hand, try to write not only about its phenomenon and versatility, but also the fact that if we take proper actions, we can prevent it from flooding the world.
Primum non nocere – first, do no harm!
Multithreading of eco-behaviours is incredibly elaborate. Attempts to create a perfect system that would reduce the amount of produced waste and simultaneously save water and minimise the carbon footprint, must be based on knowledge and, paradoxically, intuition, but first of all on common sense.
As cosmetic packaging and closures supplier we are a part of Polpak Sp. z o.o. Depending on different industry branches, the company is known for various products and services.
Coronavirus has frustrated our plans for this year. It has paralysed delivery times and forced organisers to cancel planned trade fairs.
Paradoxically, it has also strengthened our company’s values! Preaching nice and smooth slogans at calm times doesn’t require much effort.
Aluminium products are much appreciated in the packaging, food, cosmetic and industrial branches. This metal is light and easily processed, whereas products made from aluminium are relatively durable and practical.
What is it all about?
Why is one hard and transparent whereas another matt and flexible?
Why will we sleep very well on one while another will be bulletproof?
Less is more
All business branches and almost all people are in one way or another affected by the outbreak of the pandemic. Market analysts, psychologists and other experts prepare studies or speculations as to what and how has changed, how bad it is and how worse it is going to get.
Although at first glance the above motto may be a little baffling and one could wonder: 'What does that have to do with the price of tea in China?', there exists a deep connection between production and recycling.
Reduction of waste has long been a hot topic, discussed not only by the environmental organizations, but also politicians all over the world. The issue covers already existing waste, waste that is being introduced to the market, as well as future waste generation. Laws, directives and restrictions shed light on the problem and force entrepreneurs to take preventive measures in order to reduce to minimum the landfill sites that are scattered al
Over the centuries of the human existence on Earth, people’s needs have steadily increased. In ancient times, a fireplace, own cave, a piece of leather as clothing and hunting for wild animals was enough to survive. However, increased appetite, the desire for comfort and the need for an easier life were an impulse for ongoing improvements.
The very first and important stage of the recycling process is sorting waste at home. But what happens later?
Where does the waste end up and how does a PET bottle transform into a fleece sweatshirt?
The “zero waste” philosophy has recently gained great popularity. More and more followers try to live by its rules. We don’t fall behind either – we’ve already written about its multidimensionality and the fact that “zero waste” is not only about groceries and not wasting food, to which it is very often reduced. If it’s called a “philosophy”, it should apply to wider aspects of life and general lifestyle.
We often bring up the subject of ecology, sustainability, as well as care and respect for our planet. When we started introducing products made from plastic to the market, we took upon the responsibility to inform our customers and end-consumers how to deal with the packaging after use, once our products become waste.
May these Easter holidays fill your hearts with hope, faith and joy.
We wish you good health, peace and optimistic views on the future.
All the best,
Polpak Packaging Team

In 2018 the Polish Ministry of Environment launched the electronic database on waste. The aim of the register is to control waste introduced to the market, its circulation and disposal.
POLPAK Sp. z o.o.
The new year is associated with new resolutions, plans and dreams that we wish to fulfil with a new beginning. Sadly, according to the statistics most of these exciting promises go up in flames already mid-January.
Even though December is the last month of the year, devoted to important summary of the past twelve months, it is also a promising beginning of the upcoming year. During this time international analytic companies publish the results of their research and set new trends for 2020.
According to the Internet wisdom “simple solutions are the simplest”. We truly believe it and our offer reflects it. We care for our customers, hence instead of complicating their decision-making process, we try to simplify it. Sometimes less is more and a narrow selection of the finest products is the key to success. Our long experience and sales analysis show that three types of bottle caps for white co

The turn of September and October was a very intense time since we visited the industry trade fairs in the country and abroad.
Autumn is for us the beginning of a new season that we’ve been diligently preparing for for a few months now. We’ve observed the market and analysed orders made by our customers. Therefore, we’ve decided to add 9 new products to our standard, permanent distribution.
Our favourite subject is of course… packaging.
It’s our passion, job, reality and entertainment.
From dusk till dawn our Polpak team members dose, pack, send packaging and receive new inventory. We send e-mails, make phone calls and gossip about one thing only.
Total look, also known as mono look, is a timeless elegance. It applies not only to clothing or interior design elements in mono-colours, but also to cosmetic packaging. Monochromatic designs are chic and tasteful, no matter the trends or passing fads.
Dressing tables full of multicoloured bottles, dispensers, sprayers or jars may be charming, but to truly bring out elegance, they should match the interior.
The beginning of the year brought new recycling rules – what used to be three different recycling receptacles have now become six.
According to a survey conducted by Kantar TNS on behalf of the ProKarton Foundation, Poles are paying less attention to sorting waste.
For many of us summer is the most beautiful season. High temperatures, long days and sunny mornings power us up and boost us with energy for action. Vitamin D, the sunshine vitamin, charges our batteries for the rest of the year.
Every year in June we join the CosmeticBusiness trade fair in Munich and present our products to the industry members from the Western Europe.
We are living in a time when information appears in an instant and it circles the world even faster. We are flooded by news coming from each and every direction, some of which is so-called 'fake news', i.e. untrue information, the purpose of which is to be sensational, cause outrage, controversy or generate traffic to the website on which it was published. It is up to us to separate truth from falsehood, because official refutation either does

Thank you for coming to the fairs.
The pollution of our oceans, seas, rivers and forests is a topic that each of us encounters daily. Despite how much the issue is discussed, the countless conversations and conferences on it, it is still difficult to deal with it effectively. So, it is worth stressing how crucial it is that absolutely every single inhabitant of our planet is committed to tackling it. The every day choices and decisions of each individual not only have specific

Those interested in cosmetics packaging products and closures are in for a treat with a number of important events, where they will be able to see the latest and the most innovative developments in the field
A major part of it is plastic and unfortunately a lot of it is still stored in landfills. Recycling and ecology are recently one of the main topics discussed internationally, primarily because of the fact that waste production is a growing issue. How does that all relate to packaging products? Has the present situation been caused by plastics as such, or is the consumers' missing awareness to blame?
