PCR plastic packaging is a sustainable packaging solution currently gaining traction in the pursuit of limiting the environmental impacts of product waste. Many global leading brand owners have announced their sustainability commitments to incorporate PCR plastics by -. Before adopting this solution, you should consider the challenges you might face with PCR plastics. PCR is not a perfect solution, and it comes with its unique advantages and disadvantages. First, let us discuss the basics.

PCR stands for Post-Consumer Recycled. Some people use PCR as Post-Consumer Resin. PCR plastics are end products of the recycling process from used plastics. There are many types of plastics in the market, but the most common PCR materials are high-density polyethylene (HDPE) and polyethylene terephthalate (PET). The amount of polypropylene (PP) collected through recycling is less than HDPE and PET, making it less available as a PCR format. However, there are growing demands for PP PCR plastics along with HDPE and PET. The benefits of using PCR, such as reduction in total carbon footprints, and reduction of waste and use of raw materials, are already well known. However, it is vital to recognize the challenges of using PCR to make the right decisions. To understand the challenges associated with PCR, first, we must understand how it is made.
The most popularly used plastic recycling system, known as mechanical recycling, requires various steps, including sorting, cleaning, shredding, melting, and remolding. After the mechanical recycling process, used plastics become PCR resin used to manufacture plastic products once again.
Plastics are typically composed of polymers. The polymers have long-chain structures with various elements such as carbon, hydrogen, oxygen, and nitrogen. During the recycling process, the polymer chains break down, resulting in degradation. This is why it is challenging to create packaging with 100% PCR with the same durability and performance as packaging manufactured from virgin resin. Most plastic can only be recycled a few times before it becomes unusable. There has been tremendous innovation around PCR, making it possible to develop 100% PCR packaging with good performance, such as the packaging used for Colgate-Palmolive dish soap. However, it is still one of the main hurdles associated with PCR.
In addition, not all recyclable plastics are recycled—quality matters. Plastics have not only different chemical and physical properties but also different applications. For these reasons, plastics that are collected contain various materials, sizes, shapes, and colors. Even though plastics go through an intensive sorting process, PCR resin can still result in some impurities. Therefore, recycled plastics generally must have good quality to be accepted for reprocessing. On top of the challenge of finding a steady supply of PCR, brand owners who wish to use such materials are also faced with ensuring that the supply they have found is of adequate quality.
Lastly, as mentioned above, the supply of PCR plastics cannot support the growing PCR plastic demand. According to Waste Management, 25% of materials that consumers place in recycling bins do not get recycled due to contamination. While many consumers understand the importance of recycling, there is a general lack of understanding on how to recycle products.
The chart below details how the US PCR markets have changed over the past five years, polyethylene or PET, and recycled PET or rPET.
In , China stopped importing about two billion tons of plastic trash each year. Quickly, the world realized the impact and size of our global waste issue. From to , governments implemented policies to reduce virgin plastic and brands committed to circularity goals. It is a good start but still detrimental to both supply and demand.

Sadly, they do NOT mean “this is recyclable” — they merely identify what kind of plastic it is. Always check with your local recycling program for what you can recycle at home.
When in doubt, throw it out — yes, really! It’s more important to recycle the right stuff than to try to recycle everything. Too many of the wrong things can ruin an entire batch of recyclables.
There are three main ways to recycle:
Are you putting stuff in the recycling bin, but not buying products made with recycled content? We hate to break it to you, but you’re kind of missing the point of recycling.
Recycling exists to give our old stuff a new life after we’re done with it. Using recycled products conserves our natural resources and avoids the staggering environmental degradation that comes with manufacturing new stuff from scratch.
What you buy tells companies what you want in the best way that they will listen.
When you choose a sustainable recycled product over something else, you send a loud and clear signal that you want companies to make use of your recyclables. Your demand can and does create a powerful shift in how companies make and market their products.
Thanks to that increasing demand from people like you, it’s getting easier to find recycled products. Many things you’re already buying at the store or ordering online have a version made with recycled content. If you’re shopping for something truly special, you might even find a local artist who makes recycled gifts.
