Recyclable plastic bags, pure paper bags, biodegradable bags - one-stop supplier

Brands, Consumers, Various organizations and the trend of environmental protection all require products to be made with environmentally friendly materials for packaging. To this end, companies must re-evaluate or replace packaging materials ， to enhance customer loyalty 。

Recyclable plastic bags, paper bags, biodegradable bags are the three major types of popular environmentally friendly and sustainable materials today. How to choose to better meet customer requirements?

  I. What are recyclable plastic bags?

In the internationally recognized Global Recycled Standard GRS certification, EN15343:2008 certification clearly states that only pre-consumer ( pre-consumer recycled polybag ) PIR and post-consumer ( post-consumer recycled polybag ) PCR materials are considered recycled content. Greater than 20% recycled material content can apply for certification, greater than 50% recycled materials can apply for print certification LOGO label. What customers require 30% recycled、50% recycled、100% recycled refers to the proportion of recycled content by weight in a product or packaging.

Virgin material is refined from petroleum. Its characteristics are milky white, crystal clear, free of impurities, good physical properties, and easy to process. Virgin material cannot apply for GRS certification, EN15343:2008 certification. Furthermore, from the perspective of resource utilization efficiency and environmental protection, the use of virgin materials wastes resources and has adverse effects on the environment, continuously increasing the stock of plastic on Earth, which is unfavorable to the low-carbon trend.

Therefore, to meet customer requirements and practice environmental protection, recyclable plastic bags refer to certified plastic bags containing recycled content, not virgin material plastic bags.

Shunxingyuan Packaging's GRS 、 EN15343:2008 recyclable plastic bags meet customer requirements, achieve internationally recognized environmental standards, are truly recyclable and renewable plastic bags, and are important products in eco-friendly packaging.

II. What are eco-friendly paper bags?

Currently, the professional factory for eco-friendly packaging ——Shunxingyuan Packaging, in addition to producing regular laminated paper bags, also offers three more environmentally friendly paper bag products:

Glassine paper bags ， Unlike common paper bags, glassine paper bags do not contain coatings (wax, paraffin, or silicone resin) and plastic film, making them pure paper bags. Glassine paper bags are made from smooth, translucent paper, which is both durable and aesthetically pleasing, can reduce packaging waste, and are very environmentally friendly.

Cellophane bags ( cellulose film ) ， ) are made from regenerated cellulose film to make packaging bags. Cellophane bags differ from general paper bags; they are not only flexible but also transparent, just like glass, hence they are called " cellophane bags " . Cellophane bags are biodegradable paper materials, truly " green ” products.

Paper /PLA biodegradable bags, made from FSC certified paper composite biodegradable materials, possess the rigidity of composite bags, and are fully biodegradable, making them important products in eco-friendly packaging.

III. What are biodegradable bags?

Biodegradable plastic bags refer to packaging bags that fully decompose into water, carbon dioxide, and other small molecules. The main source of this fully degradable material is polylactic acid, also known as PLA, processed from corn, cassava, etc. 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 specific strains to produce high-purity lactic acid. Then, polylactic acid of a certain molecular weight is synthesized through chemical synthesis methods. It has good biodegradability and can be completely degraded by microorganisms in nature under specific conditions after use, ultimately producing carbon dioxide and water, without polluting the environment. This is very beneficial for environmental protection and is a recognized environmentally friendly material.

Shunxingyuan Packaging, through breakthroughs in advanced degradation technology and the transformation of results, can supply high-quality compostable and biodegradable bags.

Additionally, due to their characteristics, fully biodegradable bags are recommended to be stored away from light in a dry, cool, and ventilated environment, and care should be taken to prevent moisture:

1. Suitable temperature: -5℃ to 30℃

2. Relative humidity: 50% to 60%

Biodegradable bags oxidize in natural environments, so their shelf life is usually around one year.
