Abstract

The invention relates to an antibacterial micro-pore PE (Poly Ethylene) fresh-keeping film of fruits and vegetables, which belongs to the technical field of daily supplies. The antibacterial micro-pore PE fresh-keeping film of fruits and vegetables is characterized by comprising the following materials in parts by weight: 100-120 parts of P low-density polyethylene resin, 12-18 parts of ethylene-vinyl acetate resin, 9-12 parts of linear polyethylene resin, 0.2-1 part of glyceryl monooleate, 0.5-2 parts of alkyl acid amine ethoxylate, 0.3-0.8 part of antioxidant, 0.05-0.2 part of lavender essential oil, 2-5 parts of titanate coupling agent, 6-10 parts of calcium carbonate and 6-10 parts of kieselguhr. The antibacterial micro-pore PE fresh-keeping film of fruits and vegetables is stable in structure, good in transparency, tensile resistance and softness, good in air permeability and bactericidal power. Meanwhile, the antibacterial micro-pore PE fresh-keeping film of fruits and vegetables has strong adsorption effect and permeability to the gasses including O2, CO2, steam, ethylene and the like.

Description

technical field [0001] The invention belongs to the technical field of daily necessities, and in particular relates to an antibacterial microporous PE fresh-keeping film for fruits and vegetables. Background technique [0002] Plastic wrap is a kind of plastic packaging product commonly used by people to keep fresh food. Now many families cannot do without them, such as heating food in microwave ovens, storing food in refrigerators, etc. all need plastic wrap. Most of the cling film and commonly used plastic bags on the market are made of vinyl masterbatch. According to the different types of vinyl masterbatch, cling film is mainly divided into two categories: PVC cling film and PE cling film. Since PVC cling film contains carcinogens and is harmful to the human body, more and more researchers pay attention to PE cling film. [0003] The existing PE cling film has a single function, and most of the cling film does not have antibacterial function, and cannot achieve O 2 and...
