We are not unfamiliar with courier bags, we all use them when we mail items, but have we heard of biodegradable courier bags? First of all, biodegradable express bags are produced from biodegradable materials and have degradable functions. After degradation, no harmful substances will be produced, and the stretching strength of biodegradable courier bags will be stronger, even twice that of ordinary courier bags. Another point is that biodegradable express bags can be customized according to the needs of different customers. In addition, the raw materials of biodegradable express bags are mainly corn and other crop starches, which have excellent biodegradability and can be degraded by microorganisms in the soil. Carbon dioxide and water will be produced within one year after discarding, and will not cause harm to the environment. No harm, no pollution to the environment. Biodegradable courier bags are much stronger than ordinary courier bags in terms of adhesive strength, environmental protection, swing impact resistance, and tensile strength.

Secondly, the biodegradable express bag can be degraded to more than 90% within half a year. If the temperature and humidity are suitable, the biodegradable express bag can be degraded into carbon dioxide and water in a shorter time. Moreover, the biodegradable express bag is a kind of bio-packaging bag made of natural bio-based and PBAT (copolymer of butylene adipate and butylene terephthalate). In addition, the raw materials of biodegradable courier bags have high temperature requirements. Once the temperature is not well controlled, it will be difficult to process well.

Finally, because the biodegradable express bag is environmentally friendly and will not cause harm to the environment after degradation, it has been highly valued by our country and is also being widely promoted.
