Antibacterial polyethylene composition and antibacterial foamed packaging material prepared thereby

Abstract

The invention belongs to the technical field of plastic processing, and particularly relates to an antibacterial polyethylene composition and an application thereof to preparation of an antibacterialfoamed packaging material meeting a fruit packaging demand. According to the foamed packaging material prepared by the antibacterial polyethylene composition, by exerting the function of a sterilizerand uniformly mixing the sterilizer with epoxidized soybean oil, calcium carbonate, calcium oxide and oleamide, a rate of absorbing water and moisture by calcium oxide can be controlled, so that calcium oxide plays a role slowly for a long time. Regardless of storage in a refrigerator or a problem that fruits decay and go bad as the storage conditions change after the fruits are stored and delivered, the antibacterial foamed packaging material has relatively good antibacterial protecting action to fruits, so that the storage effect of the fruits can be improved effectively, and the sterilizingand quality maintaining problems of the fruits can be solved better.

Description

technical field [0001] The invention belongs to the technical field of plastic processing, and in particular relates to an antibacterial polyethylene composition and its use in preparing antibacterial foam packaging materials meeting the packaging requirements of fruit. Background technique [0002] In the process of fruit preservation and transportation, the plastic foam net used for fruit packaging has an important protective effect. It can effectively reduce friction, collision and scratches between fruit individuals, and reduce the loss of fruit in storage and circulation. For example, a typical storage condition is to wrap the selected fruit with a net and store it in a low-temperature cold storage. At a relatively low temperature, the life metabolism rate of the fruit is reduced and the shelf life of the fruit is extended. The commonly used plastic foaming net covers are mostly polyethylene resin high-foaming plastics, which have the advantage of low cost and are gener...

AI Technical Summary

Problems solved by technology

Although the above-mentioned antibacterial packaging materials can protect fruit storage to a certain extent, the silver ion antibacterial agent added to it is more expensive, which is not conducive to large-scale production. poor
