PCR, short for post-consumer resin (post-consumer recycled), is an environment-friendly packaging option that is made from recycled plastics, most commonly PET and HDPE plastic products. Instead of being sent to a local landfill, used items such as bottles, milk jugs, buckets, and industrial products like IBC totes and polydrums can be broken down, melted and reconstructed to make a resin material thats then added to create a new productPCR packaging.
PCR packaging is used to propel a continuous cycle of creating various "new" products with used recycled plastics. In addition, according to the United States Environmental Protection Agency (EPA), post-consumer recycled production reduces the reliance of fossil fuels as well as raw materials for its formulation in comparison to virgin resin products.

After consumers recycle their products, recycling plants sort the bottles according to their plastic type. Because PET and HDPE plastics are most commonly used to manufacture PCR products, these plastics are collected, washed and broken down into resin pellets. The resulting pellets are then reheated, molded and formed into new plastic containers.
PCR can be added in percentages ranging from 10% to 100% along with virgin plastic depending on the manufacturer's preference.
If post-consumer resin is used to manufacture a plastic bottle, a higher percentage can impact transparency and color. Some companies choose to incorporate less PCR in their products and more virgin resin so the material can retain the look of virgin resin. For example, if a product is composed of 25% PCR and 75% virgin resin material, then the product will look more like a virgin bottle. Additionally, many PCR plastic bottles are typically intended for products that do not require transparent packaging.
Virgin resin is the term for new and unused plastic resin without any recycled products to generate an original product. Due to its clean appearance and stable nature, virgin resin is heavily used to produce a wide variety of plastic products.
PIR, or post-industrial resin, is reworked plastic produced in the manufacturing process. PIR consists of grinded resins that were collected either from extra scrap parts during the molding stage of production or finished products that did not pass the quality control standards of the original product. Despite never being used before, the material is not considered virgin because it has been put through a second reheating process.
PIR products have not reached the consumer whereas PCR products include used material that's already reached the consumer and returned.
While PIR is reprocessed resin, PCR is made of used and recycled resin. Like PCR packaging, PIR also helps decrease the amount of plastic sent to landfills as well as reduce the demand for raw materials.
The term biodegradable is defined as the length of time it takes for plastic to fully break down and degrade by the consumption of living microorganisms such as fungi and bacteria. While PCR is a more environmentally friendly option (in comparison to virgin resin) since it's made from recycled plastic, according to The Federal Trade Commission's Green Guides, the plastic itself is not biodegradable unless it is decomposed within a year of being disposed of in landfills, incinerators and recycling plants.

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.
Degradation
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.
Impurity
In addition, not all recyclable plastics are recycledquality 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.
