Abstract

The invention discloses an environment-friendly antibacterial package film easy to degrade. The environment-friendly antibacterial package film easy to degrade is prepared from essential oil, polyvinyl alcohol with the molecular weight in a 20,000 range, polycaprolactone, metallocene polyethylene resin, corn crosslinked starch, carboxymethyl starch, biomass micro powder, langehead atractylodes rhizome extract, tourmaline powder, sodium carboxymethylcellulose, an antiblocking agent, an antifog aid, epoxidized vegetable oil, butyl octyl phthalate, sesbania gum, paraffin and carrageenan. According to the film disclosed by the invention, a lot of antibacterial raw materials easy to degrade are used as raw materials, and environment-friendly and antibacterial effects are achieved under the assistance of the appropriate aid through a reasonable proportion.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to an easily degradable environmentally friendly and antibacterial packaging film. Background technique [0002] The world produces more than 100 million tons of plastics every year, and my country's plastics account for a large proportion. According to the latest statistics from PIRA in the United States, the compound annual growth rate of demand for plastics is 7.7% from 2012 to 2017, and the compound annual growth rate of food packaging from 2012 to 2017 is 4.3%. CAGR of 5.5%. With the continuous growth of the use of plastics, the wastes of packaging plastics, agricultural plastics and various plastic products have become white garbage, causing serious environmental pollution. At present, the plastics used for packaging mainly include polystyrene, polypropylene, polyethylene, etc. These waste packaging materials after use, because they cannot be degraded, exist in the natural...
