What is the difference between GRS recycled plastic bags and new plastic bags?

The raw materials for making plastic bags can be roughly divided into two categories: new materials and recycled materials. So what are the differences between the two?

1. The difference between new material plastic bags and GRS recyclable plastic bags

New materials are refined from petroleum. Their characteristics are milky white, crystal clear particles without any impurities, good physical properties, and easy processing. Products made from new materials are generally colorless and odorless, with good gloss, etc.

Recycled materials generally come from two sources:

Post-consumer recycled materials: Materials generated by households or commercial, industrial, and institutional facilities as end-product users that cannot be reused for their intended purpose, including materials recovered from the distribution chain. That is, plastic bags that are recycled after being consumed by consumers. Post-consumer recycled materials will have a certain color, and the transparency of the plastic bags produced will be reduced.

Pre-consumer recycled materials: Materials diverted from waste streams during the manufacturing process. Excluding the reuse of certain materials, such as rework, regrinding, or residues generated during processing and reused in the same processing process. That is, plastic bags that are recycled without being consumed by consumers. Pre-consumer recycled materials will have crystal points, and unevenly distributed crystal points will be visible when viewed against a light source.

2. Advantages of GRS recyclable plastic bags

But apart from the difference in appearance, is there traceable proof of certification for recyclable and environmentally friendly plastic bags?

Of course, the authoritative international certification for recyclable recycled materials is the GRS Global Recycled Standard traceability certification.

GRS certification is a more troublesome type of factory audit. In addition to regulating the source of raw materials, it also regulates wastewater treatment and chemical use in the production process. In addition, it has strict requirements in terms of product recycling/recycled components, supply chain control, social responsibility and environmental regulations, and chemical restrictions.

Recyclable packaging bags certified by GRS are stable in quality, non-toxic, odorless, have good ductility, good texture, and are environmentally friendly.

3. Combination of recycled and new materials

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.

4. Genuine GRS recyclable plastic bag manufacturers

Sunxingyuan Packaging takes the initiative to meet the needs of customers, takes "green production" as its responsibility, adopts various measures, continuously improves recycling and reuse technology, reduces pollutant emissions, uses biodegradable substrates, etc., to optimize the production process, and successfully passed the GRS (Global Recycled Standard) certification, truly regulating the source of raw materials, regulating wastewater treatment and chemical use in the production process, and also leading the industry in product recycling/recycled components, supply chain control, social responsibility and environmental regulations, and chemical restrictions. Sunxingyuan is confident that it will continue to carry out "green production" and provide recyclable "green" packaging bags for various industries.
