Q: What are compostable bags made from?

Compostable plastics are generally made from a raw material such as corn, sugar cane and starch made from (PLA) polylactic acid. Currently, the most common raw material uses in PLA is field corn, although other plant sources are being developed. Polylactic acid (PLA) is one of the primary alternatives to traditional oil-based plastics. Polylactic acid is highly popular as a plant-based polymer (a bio-plastic) because its general performance characteristics are similar to many non-compostable polymers and can be processed in similar ways. There are some distinct performance trade-offs that must be considered when using polylactic acid as a laminate element in flexible barrier packaging, but with continued technological advancements many of these limitations are being overcome. Below is a example of a bio-plastic bottle disintegrating under composting condition.

Q: How are compostable plastics like PLA made?

Polylactic Acid is principally made through two different processes —condensation and polymerization. The most common polymerization technique is known as ring-opening polymerization. This is a process that utilizes metal catalysts in combination with lactide to create the larger polylactic acid molecules. The condensation process is similar with the principal difference being the temperature during the procedure and the by-products (condensates) that are released because of the reaction. Here are some the reasons why biodegradable and compost barrier packaging made of PLA is a great choice for many applications.

Q:Is Zipper and valve also compostable?

Yes.

Q: How long will it compostable? 

1. It will take 180 days that PLA and other biodegradable materials to biodegrade under industrial composting conditions of humidity 65%, temperature 65 degrees Celsius,90% of the organic part is degraded into water and carbon dioxide.

2. It will take 360 days to biodegrade into water and carbon dioxide in household compost of household and kitchen waste.

3. In the natural environment, the degradation of materials begins to degenerate in one year, physical properties completely lost in 3-5 years or even longer, then slowly degraded into water and carbon dioxide, the rate of degradation depends on local environmental conditions, degradation will become faster in high temperature and high humidity.
