Abstract
A biodegradable sampling bag for containing samples or the like, comprises a flexible enclosure defining a chamber adapted to contain therein the sample, the flexible enclosure being made of a plastic material, which contains an additive that renders the flexible enclosure biodegradable when exposed for a sufficient period of time to microbial action. The additive is adapted to enable microorganisms to metabolize the molecular structure of said flexible enclosure. The additive is effective in altering the polymer chain of the plastic material to allow microbial action of a suitable environment to colonize in and around the plastic material, whereby microbes can then form a biofilm on a surface of the flexible enclosure and secrete acids which break down the entire polymer chain. The flexible enclosure, when exposed to microbial action, is adapted to withstand biodegradation for a given period of time, typically of at least three months.
