Weather-resistant anti-flaming food package bag

Abstract

The invention mainly relates to the technical field of packing material processing and discloses a weather-resistant anti-flaming food package bag. The food package bag is prepared from, by weight, 36-38 parts of natural latex, 23-25 parts of modified polyurethane resin, 11-13 parts of ceramic fibers, 11-13 parts of cupper ion fibers, 7-9 parts of nanometer zeolite, 2.2-2.4 parts of nanometer titanium oxide, 0.5-0.7 part of anion powder and 0.5-0.7 part of antimony pentoxide. The provided weather-resistant anti-flaming food package bag is high in strength, excellent in bearing capability and capable of being resistant to stimulation of low temperature and high temperature, wherein the anti-flaming level reaches V-1, and great packaging and protection functions are achieved on food. According to the modified polyurethane resin, fused polyurethane resin is added into a sodium selenite solution, stirring is conducted at the constant temperature, and then fast cooling is carried out; in this way, the strength and flexibility of the polyurethane resin can be improved, and the bearing capability of the package bag is improved.

Description

technical field [0001] The invention mainly relates to the technical field of packaging material processing, in particular to a weather-resistant flame-retardant food packaging bag. Background technique [0002] Packaging bags can be seen everywhere in daily life. Common packaging bags include plastic packaging bags, paper packaging bags and non-woven packaging bags. It is seldom possible to directly microwave heating, but many consumers directly microwave food together with the packaging bag for simplicity and convenience, which will lead to the dissolution of toxic substances and cause harm to human health. Combustion will cause a great safety hazard, and the gas produced will cause harm to the human body and the environment, and the storage of food at a lower temperature will make the packaging bag hard and brittle, reducing the strength of the packaging bag and making the packaging bag in a relatively low temperature. It is easy to be damaged at low temperature, causing...

[0002] Packaging bags can be seen everywhere in daily life. Common packaging bags include plastic packaging bags, paper packaging bags and non-woven packaging bags. It is seldom possible to directly microwave heating, but many consumers directly microwave food together with the packaging bag for simplicity and convenience, which will lead to the dissolution of toxic substances and cause harm to human health. Combustion will cause a great safety hazard, and the gas produced will cause harm to the human body and the environment, and the storage of food at a lower temperature will make the packaging bag hard and brittle, reducing the strength of the packaging bag and making the packaging bag in a relatively low temperature. It is easy to be damaged at low temperature, causing bacteria to grow on the surface of food and shortening the shelf life

[0003] The existing patent document CN 106279896 A discloses a flame-retardant antibacterial food packaging material and its production method, and specifically discloses that the formula of the packaging material is made of the following raw materials in parts by weight: low-density polyethylene 100, nano-zinc oxide 2.5 -2.9, anise essential oil 5.4-6.2, sepiolite powder 2-3, activated carbon 4-6, zinc stearate 0.6-0.8, silane coupling agent KH-570 5.7-6.1, petrolatum 6-8, red phosphorus 1.2- 1.5, coniferous wood fiber 10-12, appropriate amount of water, the obtained packaging bag has strong flame retardant and antibacterial properties, but the strength of the packaging bag is low, and the load-bearing capacity is small, especially at low temperatures. The practicality of packaging materials
