Biograde B-F

Technical Datasheet | Supplied by Biograde Limited
Compostable and biodegradable plastic based on a blend of thermoplastic starch (TPS), aliphatic polyesters (AP) and natural plasticizers. Is based on corn starch which is a renewable material. Offers a high level of mechanical strength, outstanding elongation properties and toughness. Is a completely biodegradable polymer suitable for the manufacturing of film-type products. It can be directly used in the film blowing process. It does not does not contain any non-degradable polymers such as PE, PP, PS and PVC. Independent university testing shows that after biodegradation BIOGRADE B-F does not leave any harmful residues. Possesses good compatibility. The film is transparent with no granulation or lines of TPS seen in the film. Has easy film blowing performance. The film bubble is stable and no additional air cooling is needed. Exhibits thermal sealing strength is as good as PE. Used in compostable bags, shopping bags/check-out bags, garbage bags, leaf litter bags, green bin liners and overwrap packaging.
