The BPE is made from non-food fiber (Bagasse) . The product is 100% eco-friendly, chlorine free pulp material, non-wood fiber, non-toxic contamination, biodegradable in 45 days and applicable for hot & cold food. 
Polylactic acid (PLA) is a biodegradable polymer derived from lactic acid. It is a highly versatile material and is made from 100% renewable resources like corn, sugar beets, wheat and other starch-rich products. 
Polylactic acid exhibits many properties that are equivalent to or better than many petroleum-based plastics, which makes it suitable for a variety of applications. 
It is important that PLA compares well with other popular plastics already used for packaging. It is clear and naturally glossy like the polystyrene used in "blister packs" for products such as batteries, toys, and many others. 
PLA is resistant to moisture and grease. It has flavor and odor barrier characteristics similar to the popular plastic polyethylene terephthalate (PET) used for soft drinks and many other food products. Tensile strength and modulus of elasticity of PLA is also comparable to PET. 
PLA is a nonvolatile, odorless polymer and is classified as GRAS (generally recognized as safe) by the Food and Drug Administration in the United States.
