Understanding Common Eco-Friendly Packaging Bags: GRS Certified Bags, Degradable Bags, Biodegradable Bags

Eco-friendly packaging bags are increasingly used in various industries, representing a trend and a necessity for environmental protection. What are some common eco-friendly packaging bags, and can they be customized? Today, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will discuss this in detail.

1、 GRS Certified Plastic Bags

GRS Plastic bags, or recyclable plastic bags, refer to plastic bags that meet customer requirements, achieve internationally recognized environmental standards, and are truly recyclable and reusable. They are an important product in eco-friendly packaging.

Global Recycled Standard Certification GRS （ Global Recycled Standard ）is an international, voluntary, and comprehensive product standard that specifies third-party certification requirements for recycled content, chain of custody, social and environmental practices, and chemical restrictions. GRS The goal is to increase the use of recycled materials in products and to reduce and eliminate the harm caused by their production. Today, GRS is being adopted by brands such as ZARA 、 H&M 、 ADIDAS Uniqlo, NIKE IKEA, GAP etc., impacting the entire industry chain and all related supply chains.

Post-consumer recycled plastic bags: Materials generated by households or commercial, industrial, and institutional facilities as end-product users that are no longer usable for their intended purpose. Includes materials recovered from the distribution chain. That is, plastic bags recycled after consumer use.

Pre-consumer recycled plastic bags: Materials diverted from waste streams during the manufacturing process. Excludes the reuse of certain materials, such as rework, regrinding, or residues generated during processing and reused in the same process. That is, plastic bags recycled without consumer use.

Recycled content: The proportion of recycled materials in a product or packaging by weight. Only pre-consumer and post-consumer materials are considered recycled content.

GRS Plastic bags, being made from recycled waste, are very popular in foreign countries, especially in developed countries in Europe and America. Currently, Shunxingyuan Packaging is the largest and most mature GRS plastic bag production factory in China.

2. Degradable Plastic Bags

Degradable plastic bags refer to plastic packaging bags whose stability is reduced by adding a certain proportion of additives (such as starch, modified starch, or other cellulose, photosensitizers, biodegradable agents, etc.), making them easier to degrade in the natural environment.

Currently, Shunxingyuan Packaging is D2W、 ECO agent production factory.

3 Biodegradable Packaging Bags

Biodegradable plastic bags refer to plastic packaging bags that completely degrade into water, carbon dioxide, and other small molecules. The main source of this fully degradable material is corn, cassava, etc., processed into polylactic acid, or PLA . Polylactic acid ( PLA ) is a new type of bio-based and renewable biodegradable material. Starch raw materials are saccharified to obtain glucose, which is then fermented with certain strains to produce high-purity lactic acid, which is then chemically synthesized into polylactic acid with a certain molecular weight. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, eventually producing carbon dioxide and water without polluting the environment. This is a recognized environmentally friendly material.

Biodegradable Packaging Bags mainly consist of bio-based materials PLA+PBAT Under composting conditions ( 60-70 degrees) 3-6 months, it can be completely decomposed into water and carbon dioxide without polluting the environment. Currently, the biodegradable packaging bags produced by Shunxingyuan Packaging are of good quality and high yield, making them a worthwhile choice.
