Do biodegradable plastic bags have a shelf life?

Biodegradable plastic bags have biodegradability. When customizing biodegradable plastic bags, customers often worry about whether these biodegradable plastic bags have a shelf life. Can biodegradable bags still be used after their shelf life expires? And other related questions. Shunxingyuan, a professional flexible packaging manufacturer, is here to answer them.

The material composition of biodegradable plastic bags is made of PLA (Polylactic Acid) and PBAT (Polybutylene Adipate Terephthalate). These are recognized as environmentally friendly materials, harmless and green products. Under composting conditions, biodegradable plastic bags can fully biodegrade within 180 days. The degradation products are carbon dioxide and water, which are directly absorbed by plants in the soil, returning to the soil, or can degrade in the general environment without causing pollution, truly achieving 'from nature, to nature'. The use of biodegradable plastic bags greatly reduces the pollution of plastic products to the environment, truly achieving green environmental protection, health and hygiene, and peace of mind.

Biodegradable The degradation time required for plastic bags is related to their environment. In a typical daily environment, even if the time exceeds six to nine months, they will not immediately decompose and disappear. However, while their appearance remains unchanged, the physical properties of biodegradable bags begin to change, with strength and toughness gradually deteriorating over time, all of which are signs of degradation.

Biodegradable Plastic bags cannot be hoarded in large quantities; only moderate amounts should be purchased. Storage requirements include keeping them clean, dry, out of direct sunlight, and adhering to the first-in, first-out (FIFO) warehousing principle. Therefore, for biodegradable plastic bags, there's a contradiction: it's impossible to demand fast degradation while also requiring a long shelf life. Biodegradable plastic bags under natural or industrial composting conditions can degrade into carbon dioxide and water within 180 days without polluting the natural environment.
