Recently, researchers at the National Laboratory in Argonne, USA, used food-processed waste as raw materials to produce a lactic acid polymer film that can be used as a seed and fertilizer packaging material, agricultural film and paper coating materials, etc. .

The production process of the lactic acid polymer film is to first produce lactic acid from the processed food waste, then convert the lactic acid into a biodegradable lactic acid polymer, and finally make the lactic acid polymer into a film, which is used in various aspects. This new type of film not only finds new uses for food processing waste, but also reduces environmental pollution. It can be said to serve two purposes. (Source: Packaging Special Network)
