Abstract
The invention relates to the technical field of packaging materials, and discloses a biodegradable packaging material. The packaging material comprises 10-22wt% of octyl succinyl starch ester, 8-20wt% of chitosan, 8-20wt% of xylan, 8-15wt% of mannan, 10-18wt% of polycaprolactone, 1-5wt% of a compatibilizer, 1-5wt% of a coupling agent, 1-5wt% of an antioxidant and 1-3wt% of a plasticizer. The adoption of octyl succinyl starch ester and polycaprolactone as main raw materials increases the water resistance, the tensile performance and the degradability of the packaging material; and the addition of assistants improves the strength, the toughness and the heat resistance of the packaging material and reduces the production cost, and makes the biodegradable packaging material substitute general packaging materials.
Description
Technical field
The present invention relates to field of packaging material, refer more particularly to a kind of biodegradable wrapping material.
Background technology
Biodegradated polymer materal is made through microorganism fermentation or the synthetic polymer with biological degradability by natural polymer (as starch, Mierocrystalline cellulose, chitin) or agricultural byproducts, as thermoplastic starch plastic, aliphatic polyester, poly(lactic acid), PE/Starch alcohol etc. all belong to this class material.Biodegradable material is studied the more following a few class that is divided into both at home and abroad: starch, polycaprolactone (PCL), poly butylene succinate and multipolymer (PBS) thereof, poly(lactic acid) (PLA), PHA (PHA), polyvinyl alcohol (PVA) etc.Although a lot of to the research of biodegradable material and report at present, still have many problems to hinder the promotion and application of such material both at home and abroad.Reason is: the 1) poor mechanical property of degradable plastics, can not meet user's service requirements, 2) the dim jaundice of degradation material color and luster, transparency is low, and 3) on the high side, cost is higher than the production cost of common high molecular materials.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of biodegradable wrapping material, to overcome the poor mechanical property of prior art degradable plastics, and the high defect of color and luster dim jaundice price.
