What is PCR stretch film ？
In recent years, human beings have taken various environmental protection actions in order to solve actual or potential environmental problems, coordinate the relationship between human beings and the environment, and ensure the sustainable development of economy and society. If people continue to manufacture new products and turn them into garbage dumps after use, the garbage pollution of the earth will become more and more serious, and the resources that can be used on the earth will become less and less. Garbage pollution will also destroy the ecological balance, cause irreversible damage to the earth’s organisms, and continue to occupy the living space of human beings. Therefore, people first classify garbage, select available materials from classified garbage to remake raw materials, add recycled components in a new round of production, and make recyclable products, forming recycling and recycling, and promoting the concept of sustainable development . PCR stretch film came into being.
What is PCR?
PCR is one of the very popular environmental protection concepts in recent years. The full name of PCR is Post consumer recycle. As the name suggests, it means that the recycled materials come from the terminal.
There are many sources of PCR material:
1. The highest grade is food-grade material: with FDA certification, PP, PET, HDPE; from the recycling of food packaging containers such as water bottles, beverage bottles, dairy bottles, disposable lunch boxes, milk tea cups, etc.;
2. Other non-food-grade recycled materials: dismantling of home appliances, unqualified products in the production process of daily packaging materials, transitional waste generated when switching on and off, waste generated when changing the type of product produced, etc.
How to make PCR masterbatch?
The process of making PCR is divided into washing and extrusion.
The cleaning steps are descaling, high temperature sterilization, automatic sorting (material and color), manual sorting, crushing, from bottle washing to sheet hot washing, hot washing, cold washing, and drying.
The steps of extrusion are flake sorting, flake homogenization, flake storage bin, extruder and granulator, deodorizing tank, mixing and packaging.
Companies that recycle materials:
Our masterbatch is also a supplier with GRS certification. We have found 3-4 masterbatch suppliers, and the company we have established cooperation with is Zhejiang Lifu Technology Co., Ltd., a subsidiary of French Veolia.
What is GRS certification?
GRS is an international, voluntary and comprehensive product standard, and specifies the content of recycling, as well as chain of custody, social and environmental
Third-party certification requirements for environmental practices and chemical restrictions. The goal of the GRS is to increase the use of recycled materials in products, while
Timely reduce and eliminate various hazards caused in production. The GRS standard is applicable to the recovery content of 20% or more product. And for any accepted recycled material, for any supply chain. To apply for GRS certification, you must meet Its traceability, environmental protection, social responsibility, recycling mark and general principles are the five major requirements.
The new GRS certification is a three-level system, divided into copper standard, silver standard and gold standard according to the recycling standard of each product.
The gold standard requires products to contain 95%-100% recycled materials.
Silver Standard products contain 70%-95% recycled materials.
Copper Standard products contain no less than 30% recycled materials.
Advantages of PCR stretch film
- Compared with “traditional” waste disposal, recycle as much raw material as possible, which helps to minimize crude oil and protect limited natural resources, reduce greenhouse gas emissions, and realize the concept of environmental protection.
- Recycling can prevent waste of potentially valuable resources and reduce raw material consumption, thereby reducing: energy consumption, air pollution (from garbage incineration) and water pollution (from landfill). In line with the national policy of plastic reduction and double carbon, reduce carbon emissions.
- Recycling plastics saves landfill space.
- It conforms to the concept of sustainable procurement of many companies, and realizes the sustainable supply of packaging materials from the source.
Our LLDPE stretch film can meet the copper standard of GRS. In the case of technical permission, we will add as many PCR components as possible, reaching 30% and above.
