Embodiment 1

[0058] The cold-chain anti-virus and anti-bacteria masterbatch is made of the following raw materials in mass percentage:

[0059]

[0060] Its preparation method concrete steps are as follows:

[0061] Weigh a certain weight of materials according to the formula, put them into a high-speed mixer and stir for 5 minutes, transport the uniformly mixed materials into the hopper of the extruder, and extrude and granulate through the twin-screw extruder. Rotational speed: 65N / min; temperature control: 160°C; the masterbatch is obtained by air-cooling and hot-cutting at the machine head, packed into bags (25kg / bag), and put into storage for standby.

Embodiment 2

[0063] The cold-chain anti-virus and anti-bacteria masterbatch is made of the following raw materials in mass percentage:

[0064]

[0065] Its preparation method concrete steps are as follows:

[0066]Weigh a certain weight of materials according to the formula, put them into a high-speed mixer and stir for 5 minutes, transport the uniformly mixed materials into the hopper of the extruder, and extrude and granulate through the twin-screw extruder. Rotational speed: 50N / min; temperature control: 150°C; the masterbatch is obtained by air-cooling and hot-cutting at the machine head, and after bagging (25kg / bag), it is put into storage for standby.

Embodiment 3

[0068] The cold-chain anti-virus and anti-bacteria masterbatch is made of the following raw materials in mass percentage:

[0069]

[0070] Its preparation method concrete steps are as follows:

[0071] Weigh a certain weight of materials according to the formula, put them into a high-speed mixer and stir for 5 minutes, transport the uniformly mixed materials into the hopper of the extruder, and extrude and granulate through the twin-screw extruder. Rotational speed: 80N / min; temperature control: 175°C; the masterbatch is obtained by air-cooling and hot-cutting at the machine head, and after being bagged (25kg / bag), it is put into storage for standby.

Abstract

The invention relates to a cold-chain anti-virus and anti-bacteria ethylene gas absorption preservative film (bag) and a preparation method thereof, and belongs to the technical field of chemical engineering. The preservative film (bag) is mainly used for packaging fresh fruits and vegetables. According to the cold-chain anti-virus and anti-bacteria ethylene gas absorption preservative film (bag), a cold-chain anti-virus and anti-bacteria master batch is added into preparation raw materials of the preservative film (bag), and the cold-chain anti-virus and anti-bacteria master batch is prepared from the following raw materials in percentage by mass: 0.5-1.5% of silver oxide, 0.5-1.5 %of an antioxidant 215; 0.5%-1.5% of an antifogging and dripping agent LY-6; and 95.5-98.5 % of LLDPE powder, wherein the LLDPE powder is one of 9085 or 7042 or a mixture of 9085 and 7042 in any proportion. The preservative film (bag) can be quickly dissolved to kill viruses and bacteria and eliminate mist and ethylene gas released by fruits and vegetables in the packaging material; and the preparation method is scientific, reasonable, simple and easy to implement.

Description

technical field [0001] The invention relates to a cold-chain anti-virus and anti-bacteria fresh-keeping film (bag) for absorbing ethylene gas and a preparation method thereof, belonging to the technical field of chemical industry. The fresh-keeping film (bag) is mainly used for packaging fresh fruits and vegetables. Background technique [0002] With the continuation of the new coronavirus and the development of the mutated Delta virus, it is urgent to block the virus transmission during the cold chain packaging, storage, and transportation, including the safety of the packaging and storage of fresh fruits and vegetables. It has anti-virus and anti-bacterial absorption. Functional packaging of ethylene gas fresh fruit and vegetable plastic wrap (bag). Completely cut off the source of transmission, so as to cut off the spread of viruses and germs during the food chain, and add a safety barrier to people's daily life. [0003] At present, most of the packaging bags and handba...
