Antibacterial CPP film and production method thereof

Abstract

The invention discloses an antibacterial CPP film which is composed of a heat sealing layer, a middle layer, a secondary surface layer and a corona layer, wherein the heat sealing layer is composed of co-polypropylene, an antibacterial agent, PE-g-MAH, LDPE and a slipping agent; the middle layer is prepared from homo-polypropylene, EPDM, HDPE, an antistatic agent and a slipping agent; the secondary surface layer is prepared from co-polypropylene, sodium phosphate, HIPS, bicyclo [2.2. 1] heptane-2, 3-dicarboxylic acid disodium and talcum powder; the corona layer is composed of co-polypropylene, EVA, calcium carbonate, HDPE, a stabilizer and a lubricant. The antibacterial CPP film has the advantages of good antibacterial effect, good toughness, good glossiness and the like.

Description

technical field

[0001] The invention relates to an antibacterial CPP film and a production method thereof. Background technique

[0002] There are a large number of microorganisms in the human living environment, and they will multiply rapidly under suitable temperature and nutrients, resulting in material deterioration, corruption, mold, etc. Food packaging materials, due to direct contact with food materials, have the ability to block oxygen and humidity. The main performance of food packaging materials is to prevent the external environment from affecting the food. The barrier properties include oxygen barrier properties, moisture barrier properties, light barrier properties, and odor barrier properties. High temperature resistance and low temperature resistance are also ideal properties for food packaging materials. Although most of the current food packaging materials can meet the above needs, there are deficiencies in antibacterial properties, especially for fresh foo...
