Abstract

The invention discloses an antibacterial and degradable plastic packaging bag for marinated foods. The antibacterial and degradable plastic packaging bag is prepared by the following materials in parts by weight: 100 parts of low-density polyethylene, 20-25 parts of polybutylene succinate, 2-6 parts of polyvinyl alcohol, 2-6 parts of polyhydroxyalkanoate, 1-3 parts of polylactic acid, 1-3 parts of polymethyl ethylene carbonate, 2.4-2.6 parts of nano zinc oxide, 6-8 parts of clove essential oil, 1.2-1.5 parts of potassium sorbate, 2-3 parts of shell powder, 1-2 parts of bacterial cellulose, 11-13 parts of enteromorpha fibers, 2-3 parts of konjak sol, 1-2 parts of castor oil, 2-3 parts of silicon oxide and 1-2 parts of dioctyl maleate. The antibacterial and degradable plastic packaging bag disclosed by the invention has the advantages that the low-density polyethylene is adopted as a base material, nano zinc oxide treated by the konjak sol is adopted as a photocatalytic antibacterial agent, so that the antibacterial and degradable plastic packaging bag still has stronger antibacterial property and high antibacterial even though broad-spectrum property even under the condition of no light; and simultaneously the modified shell powder is used as a filler, so that the adsorbability is strong and the prepared antibacterial plastic packaging bag for the foods is environmentally friendly and degradable.

Description

technical field [0001] The invention belongs to the technical field of food packaging, and relates to an antibacterial and degradable halogenated food plastic bag. Background technique [0002] Microorganisms are small in size, various in variety, rapid in reproduction and strong in adapting to the environment, and are widely distributed in nature. Most foods are rich in nutrients and high in water content, so they are easily contaminated by microorganisms and cause spoilage, which greatly shortens the shelf life of foods. How to prevent microbial contamination of food and prolong the shelf life of food has always been a subject of research and concern by relevant scientists all over the world. With the development of science and technology, food packaging materials prepared by antibacterial technology can become a practical and reliable antibacterial solution. [0003] The market has increasing requirements for food packaging materials, hoping to extend the shelf life for...
