Problems solved by technology

[0002] At present, the packaging films commonly used by people are mainly polyethylene or polyvinyl chloride plastic films. These plastic films are difficult to degrade and have poor antibacterial ability, which not only causes environmental pollution, but also brings some safety hazards; in addition, traditional packaging films The strength, stiffness and barrier properties of the material need to be further improved

Abstract

The invention provides an antibacterial biological nano packaging film and a preparation method thereof. The packaging film is prepared from the following raw materials in parts by weight: L-polylactic acid, gelatin, polyhydroxybutyrate, esterification-modified nano cellulose, nano medical stone powder, nano cerium oxide, nano copper powder, carbon nano fibers, nano kaolin, gliadin, fucosan sulfate, natamycin, alangiym root powder, glycyrrhizic acid, zinc acetate, vitamin E, sodium alginate, polyethyleneglycol 500 and dioctyl phthalate. By using various existing appropriate nano materials according to the proper proportioning, the prepared packaging film product has the advantages of favorable antibacterial property, favorable mechanical properties, favorable barrier property and favorable comprehensive properties, and can satisfy the application requirements in the field of packaging films.

Description

technical field [0001] The invention belongs to the field of packaging materials, and in particular relates to a bacteriostatic biological nanometer packaging film and a preparation method thereof. Background technique [0002] At present, the packaging films commonly used by people are mainly polyethylene or polyvinyl chloride plastic films. These plastic films are difficult to degrade and have poor antibacterial ability, which not only causes environmental pollution, but also brings some safety hazards; in addition, traditional packaging films The strength, stiffness and barrier properties of the material need to be further improved. With the increasing lightness and functionalization of packaging materials, new requirements are put forward for packaging materials. [0003] Nanomaterials refer to materials with at least one dimension in the nanoscale range (1-100nm) or composed of them as basic units in three-dimensional space. Effect and other special effects, which hav...
