What is biodegradable packaging bag?
100% biodegradable packaging bags are made from organic materials such as plant-based polymers,Such as PLA materials, as the raw materials are starch. paper, or compostable plastics. They are designed to break down into natural elements like water, carbon dioxide, and biomass through natural processes like microbial digestion or exposure to sunlight and oxygen. These bags provide an eco-friendly alternative to traditional plastic bags, which can take hundreds of years to decompose.
Lehua Packaging are always keen on new environmentally friendly materials packaging bags manufacturing.
Because echo-friendly materials biodegradable packaging bags are bags made from materials that can break down and decompose naturally over time. These bags are designed to minimize environmental impact by reducing the amount of waste that ends up in landfills or oceans.
The 100% compostable packaging do not contaminate soil or emit harmful gases after using.
Why we use PLA starch materials to make a bag?
That is because starch is initially released by microorganisms. This enzymatic breakdown transforms the plastic material into a porous structure, increasing its surface area. This enhanced surface area facilitates further enzymatic degradation or natural decomposition.
What sets our bags apart is the inclusion of automatic oxidizing agents, such as unsaturated fatty acids, within the plastic. These agents react with metal salts present in soil or water, generating peroxides that break the long polymer chains. As a result, the molecular weight of the polyolefin polymers decreases to a certain extent, making them susceptible to bacterial or enzymatic degradation. Ultimately, this degradation process leads to the generation of small molecular compounds, such as carbon dioxide and water, which seamlessly reenter the natural cycle.
