Embodiment Construction

[0015] A good heat-resistant sealing food packaging bag, made of the following components by weight: linear low density polyethylene 160, chopped carbon fiber 0.8, acetyl tributyl citrate 1, glycerol monostearate 2, corn Whisker fiber 8, nano-attapulgite 12.5, sorbitol 1, diethyl malonate 0.8, chitosan 3, heat-resistant modifier 0.7;

[0016] The particle size of the nano-attapulgite is 22-23nm, and the nano-attapulgite is pretreated: the nano-attapulgite is soaked in a mixed solution of ethanol and stearic acid mixed in a mass ratio of 100:3 for 30 minutes. Control at 25-26°C, then filter and dry the surface;

[0017] The preparation method of the corn silk fiber is as follows: take 25 parts by weight of corn silk, soak it in a sodium carbonate solution with a mass concentration of 1.5% for 15 minutes, filter, then add it to a hydrochloric acid solution with a mass concentration of 5.5%, and heat to 28-32°C for 10 minutes, then filter, wash with water, add water twice the we...

Abstract

The invention discloses a food packaging bag with the good heat sealing resistance. The food packaging bag is prepared from linear low-density polyethylene, short carbon fibers, acetyl tributyl citrate, glycerol monostearate, corn stigma fiber, nano-attapulgite, sorbitol, diethyl malonate, chitosan and a heat-resistant modifying agent. According to the food packaging bag, the high temperature resistance is achieved, and the flexibility is good; through the mutual synergistic effects of all the ingredients, the longitudinal tensile strength can reach 18.5 MPa or above, the transverse tensile strength can reach 16.5 MPa or above, therefore, the comprehensive mechanical property of the food packaging bag is improved, the branching degree and the vitrification temperature of the food packaging bag are greatly increased, and the decomposing temperature of the food packaging bag is increased; the anti-aging capacity and the stability to light and heat are greatly improved, and the oxidation resistance, the chemical resistance and the antibacterial property are all greatly improved.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a good heat-resistant sealing food packaging bag. Background technique [0002] With the improvement of domestic consumption level, the pace of life of urban and rural residents is accelerated, and food packaging bags are needed in the production of instant noodles, rice, porridge, bread, etc., as well as cooked food products such as convenient livestock meat, stored meat, aquatic products, eggs, and vegetables. And for these food packaging bags that need to be cooked, they are required to be completely free of bacteria and air. The most important performance is that they have high temperature sterilization performance and high barrier properties to water vapor and oxygen. Because high-temperature resistant cooking is mainly used to preserve meat products, and meat products multiply quickly in the presence of moisture and air, resulting in spoilage and deterioration. However, the food pac...
