As global environmental awareness continues to increase, the coffee industry is facing the challenge of sustainable development.

Traditional coffee packaging mostly uses plastic composite materials. Although it can effectively preserve freshness, it has caused a long-term burden on the environment. 

Biodegradable coffee packaging bags are becoming a new trend in the industry, and the reasons behind it are worth exploring in depth.

1. Reduce plastic pollution and protect the ecological environment

Traditional coffee bags are usually made of multiple layers of plastic (such as PE, PP) and aluminum foil. 

These materials are difficult to degrade naturally and can remain in the natural environment for hundreds of years.

 According to research statistics, about 25 billion non-biodegradable coffee packaging is produced worldwide each year, most of which end up in landfills or oceans, 

threatening wildlife.

✅ Biodegradable materials (such as PLA, PBAT, etc.) can be decomposed into water, carbon dioxide and organic matter under certain conditions (such as industrial composting), 

greatly reducing "white pollution".

2. Protect the freshness of coffee beans and improve the quality experience

Although traditional plastic packaging can block air in the short term, long-term storage may still cause coffee beans to oxidize and lose flavor. 

The biodegradable coffee bags can not only meet environmental protection needs through innovative material technology, 

but also better protect the freshness and aroma of coffee beans. The specific advantages include:

✅ Optimize air permeability: Some biodegradable materials have a microporous structure, which can balance oxygen barrier and carbon dioxide emission, 

and prevent coffee beans from producing "stuffy taste" due to excessive sealing.

✅ Moisture-proof and anti-oxidation: Using bio-based coating instead of aluminum foil can not only block moisture, 

but also reduce the impact of metal residue on coffee flavor.

✅ No risk of chemical migration: Traditional plastics may release trace plasticizers, while food-grade biodegradable materials (such as PLA) are safer, 

ensuring the purity of the original coffee aroma.
