What Is PCR Plastic? The Pros and Cons of PCR Packaging
What is PCR Packaging?
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 that’s then added to create a new product—PCR 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.

Pros of PCR Packaging
- The recycled resin reduces the amount of waste that is landfilled and reduces the use of fossil fuels which, in turn, improves the environmental impact of plastic packaging. PCR packaging appeals to eco-conscious consumers, and, studies suggest that people, particularly generations Gen Z and millennials, are committed to having a positive impact on the environment, indicating PCR plastics are the way of the future.
- PCR allows manufacturers to produce high-quality products like a virgin resin product would at competitive prices while reducing their environmental impact. The grade of PCR plastics is equally matched with regular plastic film in terms of protection, performance, and strength. Post-consumer resin blocks light, oxygen, and other gases from seeping into the package.
- PCR packaging can be suitable for food-contact use if it meets the FDA Guidelines.
- These plastics decrease carbon footprints (the total amount of greenhouse gases produced by our actions).
Cons of PCR Packaging
- The required reheating process in creating PCR plastics can alter the color and clarity of the product depending on the amount of resin that is added. This process does not hinder the function or durability of the bottle. Manufacturers can shy away from using post-consumer resin because the dark properties of the bottle do not fit the aesthetic they want to portray for their packaging.
- Benefits of PCR plastic are dependent on the consumer recycling their products.
- Price of manufacturing is contingent on the amount of plastics recycled.
How Is PCR Used?
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.
What is Virgin Resin?
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 PCR? Reprocessed vs Recycled
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.
Is PCR Packaging Biodegradable?
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.

Post-industrial recycled plastic: What is it?
The term post-industrial recycled plastic refers to plastic materials discarded in industrial processes that do not reach the market for final consumer sale. This includes production waste, cut-offs, or scraps from manufacturers using plastic in their production processes.
Post-industrial plastic is typically of fairly good quality and can be recycled and reused for the same production process or for the creation of new plastic products. By recycling this type of plastic and reintegrating it into the same transformation process, it prevents it from ending up in landfills and contributes to a more sustainable use of resources.
Examples of post-industrial plastic may include manufacturing waste from packaging such as bottles and jerrycans, pipe waste, electronic components, among others. These waste materials are collected, sorted, and processed by a waste manager to give them a new purpose, avoiding the use of virgin plastic and reducing environmental impact.
Post-consumer recycled plastic (PCR): What is it?
Post-consumer recycled plastic, or PCR, refers to plastic that has been collected, sorted, and processed to be reused after its life as a consumer product. This means the plastic has been used by consumers and then recycled for subsequent use in manufacturing new products. Using post-consumer recycled plastic to manufacture new products helps reduce the amount of plastic waste in landfills and conserves the natural resources used in virgin plastic production.

Disadvantages of using post-consumer plastic for plastic packaging
- Reduced quality and durability: In some cases, recycled plastic may have lower quality and durability than virgin plastic, affecting the lifespan of the packaging.
- Residual contamination: Post-consumer recycled plastic, obtained through mechanical recycling, may contain traces of contaminants acquired during its original use, affecting the safety or quality of the final product.
- Higher cost: The collection, sorting, and recycling process of post-consumer plastic can be more expensive than virgin plastic production, potentially impacting the final packaging price.
- Technical limitations: Some applications of plastic packaging, especially those requiring high transparency or strength, may face technical limitations when using recycled plastic.
Homologation of post-industrial and post-consumer recycled plastic for use in new packaging
Both post-industrial and post-consumer recycled plastic must be homologated for use in the manufacturing of new packaging. Homologating recycled plastic involves subjecting it to tests and analyses to ensure it meets the necessary quality and safety requirements for use in packaging.
This ensures that recycled plastic does not contain hazardous substances and has the proper mechanical properties to fulfill its function as packaging. Homologation is also crucial to guarantee the traceability of recycled materials and promote transparency in the recycling process.
There is no single global standard for homologating recycled plastic. Many countries have regulations and standards related to recycling and waste management, including post-consumer plastic. These standards may vary depending on the country and its environmental legislation.
The European standard specifying the necessary procedures for the traceability of recycled plastics is UNE-EN . This standard provides the basis for calculating the recycled content of a product: "Recycled plastics. Traceability and assessment of conformity for recycled plastics and recycled content." It establishes requirements and test methods for recycled plastics from municipal solid waste and mechanical recycling of plastic packaging, enabling them to be used in the manufacturing of non-food products.
UNE-EN is a European standard that sets requirements and test methods for recycled plastics intended for use in manufactured products. Its goal is to ensure that recycled plastics have suitable properties for use in products, complying with quality and safety standards.

The standard establishes criteria for classifying recycled plastics into different categories based on their origin, recycling processes, and technical characteristics. It also sets minimum quality requirements for these recycled plastics, including physical, mechanical, and thermal properties.
Additionally, it defines the testing methods that should be used to determine the properties of recycled plastics, including tests for strength, hardness, density, thermal stability, among others.
UNE-EN standard: Why is it important?
Its importance lies in standardizing the requirements and test methods for recycled plastic used in plastic products. It is crucial for promoting the use of recycled plastic as an alternative that supports sustainability, reduces the environmental impact of plastic waste, and fosters a circular economy.
The UNE-EN standard establishes quality and safety criteria to ensure that recycled plastic meets the technical and health requirements necessary for its use in plastic products. This is essential to ensure that products made with recycled plastic are safe for users and comply with established technical specifications.
In conclusion, the homologation of recycled plastic, whether post-industrial or post-consumer, plays a fundamental role in the transition to a circular and sustainable economy. The UNE-EN standard serves as an essential pillar by setting rigorous criteria for the quality and safety of recycled plastics used in the manufacturing of new products.
This standard not only contributes to reducing the environmental impact of plastic waste but also promotes environmental awareness and encourages the adoption of more responsible practices in plastic material management. Adhering to these standards promotes the creation of more sustainable packaging, mitigating the negative effects of plastic on the environment and moving towards a greener future.
