Abstract

The invention discloses an antifogging antibacterial PET sheet, which is prepared from the following components in percentage by weight: 85% of a PET resin, 5% of an antifogging surfactant, 1% of a lubricant, 1% of a demolding agent, 3% of a toughening agent, 3% of an antistatic agent and 5% of antibacterial master batch. The antifogging antibacterial PET sheet has the beneficial effects that nano titanium dioxide can kill bacteria, decompose formaldehyde, decompose acetaldehyde and decompose ethylene, and five functions of combination, antifogging, sterilization, ethylene decomposition and breathing inhibition are integrated together through modification and compounding of materials to form a novel fresh-keeping technology and a novel functional packaging material; and a packaging material and a fresh-keeping technology are integrated, the material is very convenient to apply, a simple, rapid and low-cost fresh-keeping method of products is realized, the defect of insufficient fresh-keeping capability of agricultural products in producing areas can be overcome, and the problem which cannot be solved in the past is solved.

Description

technical field [0001] The invention belongs to the technical field of films, and in particular relates to an anti-fog and antibacterial PET sheet. Background technique [0002] The traditional vacuum is used to block the air; the films on the market are combined films, which block the air in this way, and at the same time, play a barrier role in packaging to extend the shelf life of food. During the storage, transportation and sales of vegetables and fruits, a large amount of water vapor will be volatilized, condensed to the inner surface of the packaging, forming water vapor, and then flowing to the vegetables and fruits to accelerate the decay of vegetables and fruits, increase the growth of bacteria, cause a large amount of water loss, and rot and deteriorate. [0003] In order to solve the shortcomings of insufficient freshness preservation ability of agricultural products, anti-fog, sterilize, decompose ethylene, and inhibit breathing, we propose an anti-fog and antiba...
