Recently, the environmental impact of persistent plastic
packaging wastes is raising general global concern,
since disposal methods are limited. Ever increasing concerns
have been raised over environmental burdens and
exhausting natural resources caused by non-biodegradable
plastic packaging materials and over food safety caused on
increased demand for biodegradable packaging materials
from renewable sources (biopolymers) as an alternative
to synthetic plastic packaging materials, especially for use
in short-term packaging and disposable applications such
as disposable cutlery, disposable plate, cups and utensils,
diapers, trash bags, beverage containers, agricultural
mulching films, fast food containers, medical devices, etc.
