Degradable plastics

Jolly Sunshine Limited | Updated: Nov 16, 2018

None of the commodity plastics degrades rapidly in the environment. Nevertheless, some scientists and environmentalists have seen biodegradable and photodegradable plastics as a solution to the problem of litter. Some “bioplastics” have been developed, but they have not been successful on a large scale primarily because of high production costs and problems of stability during their processing and use. Game card binder with elastic strap.9-pocket binder

On the other hand, the plastic rings that hold six-packs of soft-drink and beer cans together represent an application where photodegradation has been used effectively. A copolymer of ethylene with some carbon monoxidecontains ketone groups that absorb sufficient energy from sunlight to cause extensive scissioning of the polymer chain. The photodegradable plastic, very similar in appearance and properties to low-density polyethylene (LDPE), decomposes to a powder within a few months of exposure in sunny climates. Game card binder with elastic strap.9-pocket binder
