Abstract

The invention provides a degradable food packaging film material and a preparation technology thereof, and relates to a high-strength-and-ductility fully-degradable biopolyester composite and a preparation technology thereof. The degradable food packaging film material is characterized by being prepared by taking aliphatic polycarbonate, lactic acid, poly(beta-hydroxybutyrate-co-beta-hydroxyvalerate), 4-arm-polyethylene glycol propionaldehyde, chitosan, 8-arm polyethylene glycol polyhedral oligomeric silsesquioxane, stannous octoate, stannous chloride, a melt reinforcing agent and an antioxidant as raw materials in a reaction extrusion mode. The biomass composite is simple in processing technology, has excellent strength and ductility, can be fully degraded, and can be suitable for packaging and industrial fields requiring high strength and ductility.

Description

technical field

[0001] The invention relates to a method for preparing a food packaging film, in particular to a method for preparing a fully degradable film material with good mechanical properties and no harm to food. Background technique

[0002] Although plastic materials have excellent performance and wide applicability, they are derived from petroleum products and cannot be degraded. In today's resource crisis and environmental pollution are becoming more and more serious, looking for excellent performance and renewable alternative materials has become the current research field in the field of materials. top priority.

[0003] Among the current degradable materials, various biodegradable materials are used in plastic replacement. Such as starch, polylactic acid, biopolyester, etc. Starch has been deeply studied due to its cheap price and wide range of sources, and a variety of daily and industrial products have been prepared through modification and compounding, suc...
