The invention provides an antibacterial packaging film. The antibacterial packaging film comprises a nanometer antibacterial layer, a blocking layer, a surface layer and an adhesion layer, wherein the adhesion layer is connected with the nanometer antibacterial layer, the blocking layer and the surface layer, the nanometer antibacterial layer comprises the following ingredients in parts by weight: 70-150 parts of LDPE (Low-Density Polyethylene), 20-60 parts of LLDPE (Linear low density polyethylene), 30-50 parts of silver ion antibacterial agent, 4-8 parts of polyethylene wax, and 3-7 parts of stearic acid. The preparation process provided by the invention comprises the following steps of: feeding antibacterial master batch, the blocking layer, the surface layer, and an adhesion agent into different hoppers of an extruding machine respectively, and carrying out co-extrusion casting composition to obtain the co-extruded antibacterial packaging film. The packaging film provided by the invention is excellent in antibacterial performance and high in blocking performance; even the food which is especially sensitive to air can be stored for quite long time after being packaged by using the film, and no air can enter into the packaging film to cause color change; in addition, by virtue of the outer layer structure, the optical performance, the mechanical performance, the surface printing capacity, the tensile capacity, and the high temperature hot sealing resistance of the packaging film are improved.
Description
Technical field
The invention belongs to the packing technique field, be specifically related to a kind of anti-bacterial packaging film and preparation method thereof.
Background technology
The safety and sanitation of food are direct and the life and health people is closely bound up, and therefore selecting suitable packaging material is one of important controlling units that guarantee food quality.The barrier property of packaging material is key factors of impact packing effect, and rotten main cause occurs many packing content things is that chance visible ray and microorganism and the metabolism of himself cause due to moisture and oxygen invasion and attack.Moisture makes microbial reproduction, and oxygen makes content oxidation, rotten, and some food are met visible ray can decomposition failure.Barrier property is good, and in the guarantee packing, content keeps its original characteristic not change; Barrier is bad, easily makes moisture in packing content thing air amount and oxygen cause rotten, or photolysis occurs, and causes loss of drug potency, and simultaneously, the dissolvent residual of packaging film also can be to the mass formation certain influence of food.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art and a kind of anti-bacterial packaging film is provided.
A kind of anti-bacterial packaging film, comprise the described nano-antibacterial layer of nano-antibacterial layer, barrier layer, extexine and connection, barrier layer, between adjacent layer, by binding agent, fixes; Wherein, described nano-antibacterial layer, in components by weight percent, comprises LDPE70～150 part, LLDPE20～60 part, 30～50 parts of silver ion antimicrobial agents, 4～8 parts of Tissuemat Es, 3～7 parts of stearic acid.
In above-mentioned anti-bacterial packaging film, the material of described barrier layer is ethylene-vinyl alcohol copolymer or polyamide.
In above-mentioned anti-bacterial packaging film, the material of described extexine is metallocene PE or polypropylene.
In above-mentioned anti-bacterial packaging film, described binding agent is vinylacetate-ethylene copolymer or maleic anhydride modified ethene polymers.
The preparation method of above-mentioned anti-bacterial packaging film comprises the following steps:
(1) by the nano-antibacterial layer, LDPE, LLDPE, silver ion antimicrobial agent, Tissuemat E, stearic acid used mixes with high-speed mixer, with the double screw extruder granulation, obtains antibacterial plastic concentrate afterwards;
(2) antibacterial plastic concentrate, barrier layer, extexine, binding agent are put into respectively to each hopper of extruder, the compound co-extrusion anti-bacterial packaging film that obtains of coextrusion casting, the concrete technology parameter is: 210～250 ℃, nano-antibacterial layer, 70～130r/min, 200～240 ℃ of barrier layers, 80～150r/min, 230～260 ℃ of extexines, 60～140r/min, 210～250 ℃ of binding agents, 70～130r/min.
The present invention compared with prior art its remarkable advantage is: have excellent antibiotic property and high barrier, even responsive especially food is after longer storage period to air, also because oxygen enters, color change does not occur fully.And optical property, mechanical property, surface printing ability, stretch capability, high temperature resistant envelope that layer structure also can improve packaging film are boiling hot.
