Current trend in the fresh produce packaging sector is characterized by the high reliance on ecofriendly packaging materials such as biopackaging materials from corn starch and potato starch and PLA packaging materials from fermented agricultural products.
Biopackaging Materials: Biopackaging materials are manufactured from renewable raw materials like starch from maize or grains; potato starch and fossil fuels. Biopackaging is now widely practiced in ecofriendly manufacturing facilities. Asia-Pacific based Convex Plastics is a leading supplier of biopackaging material in the world.

PLA Packaging Materials: PLA films, an ecofriendly packaging solution are increasingly becoming a viable packaging option for fresh produce sector. PLA is bio-based as it is derived from the fermentation of agricultural products and also biodegradable. PLA is popular as a sustainable alternative to petrochemical-derived polymers. Since PLA does not leave waste and can be composted in industrial facilities itself, it becomes a preferred packaging solution for the facilities where waste management becomes a herculean task. Nevertheless, PLA has certain disadvantages also. It is highly brittle and less durable as compared to petroleum-derived polymers. However recent researches have shown that this flaw can be rectified by using certain additives to incorporate into the PLA films during the manufacturing process. Asia- Pacific based Convex Plastics is a major supplier of PLA packaging solutions in the world.
NatureWorks from Convex Plastics: NatureWorks is a PLA packaging material introduced by Convex Plastics. It is made from fermented corn and is easily degradable into compost within a span of 4 -6 weeks. Its best use is for the production of lidding films.
