Multi-layer co-extrusion casting mildew-proof antibacterial film

Technical Field

The utility model relates to an antibacterial film technical field specifically is a mould proof antibacterial film of multilayer crowded curtain coating altogether.

Background

Antibacterial is a general term that includes sterilization, disinfection, bacteriostasis, mold prevention, corrosion prevention, and the like. Chemical or physical methods are used to kill bacteria or interfere with the growth and reproduction of bacteria and their activity. Is a general term for sterilization and bacteriostasis. Under definite indication, the proper antibiotic is selected, and proper dosage and treatment course are adopted to kill pathogenic bacteria and control infection, and various corresponding measures are adopted to enhance the immunity of patients and prevent adverse reactions, especially avoid the generation of bacterial drug resistance. The scientific interpretation of the film is: a two-dimensional material formed by deposition of atoms, molecules or ions on a substrate surface. The film is widely used in the industries of electronics, machinery, printing and the like.

The common mildew-proof antibacterial film is added with the same content of mildew-proof antibacterial agent on each layer or coated with a layer of mildew-proof antibacterial agent on the surface through secondary processing, the cost is higher, the production process is not environment-friendly and is not beneficial to large-scale use, and the thickness of the mildew-proof antibacterial layer can not be freely adjusted due to the old manufacturing material of the traditional mildew-proof antibacterial film, so that the mildew-proof antibacterial film which can meet the requirements of mildew resistance and bacteria resistance, can freely adjust the content of the mildew-proof antibacterial agent and has lower cost is urgently needed.

SUMMERY OF THE UTILITY MODEL

The utility model provides a not enough to prior art, the utility model provides a mould proof antibacterial film of multilayer crowded curtain coating altogether has solved the antibiotic membrane of ordinary curtain coating mould proof and has wholly all added mould proof antibacterial agent, and the cost is higher, is unfavorable for using on a large scale to traditional mould proof antibacterial agent membrane's preparation material is old, can not freely adjust film thickness's problem.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a mould antibiotic film is prevented to multilayer coextrusion casting, includes plastic film layer, its characterized in that: the material of plastic film layer is one of PE, EVA, PP, POE, TPE, TPO, TPU, or PVC, one side of plastic film layer is provided with mould proof antibacterial agent layer, the material on mould proof antibacterial agent layer is one of PE, EVA, PP, POE, TPE, TPO, TPU, or PVC wherein.

Preferably: the side of the mildew-proof antibacterial agent layer, which is far away from the plastic film layer, is provided with a pattern layer, and patterns or embossing paths can be arranged on the pattern layer.

Preferably: the other side of the plastic film layer is also provided with a mildew-proof antibacterial agent layer, namely the plastic film layer is arranged between the two mildew-proof antibacterial agent layers.

Preferably: the plastic film layer can be arranged into 1-4 layers.

Advantageous effects

The utility model provides a mould proof antibacterial film of multilayer crowded curtain coating altogether. Compared with the prior art, the method has the following beneficial effects:

(1) this mould antibacterial film is prevented to multilayer coextrusion casting, the material on the mould proof antibacterial agent layer of one side of plastic film layer is PE, EVA, PP, POE, TPE, TPO, TPU or PVC one of them, the multilayer coextrusion technique realization thickness of plastic film layer and mould proof antibacterial agent layer accessible advanced film can freely be set for in this mould proof antibacterial film is altogether crowded to multilayer, can increase or reduce the thickness on each composition layer according to actual demand, so that adjust the content of mould proof antibacterial agent in the mould proof antibacterial film, reduction in production cost, so that make it satisfy mould proof antibacterial effect, and through the setting on pattern layer, can have efficiency such as antiskid when making the finished product.

(2) This multilayer is crowded casting mould proof antibacterial film altogether, the opposite side of plastic film layer (1) can set up antibacterial agent layer (2), be the plastic film layer in the middle of two-layer antibacterial agent layer promptly, through the setting on mould proof antibacterial agent layer, especially the surface on plastic film layer only sets up one deck mould proof antibacterial agent layer, mould proof antibacterial agent layer thickness is very reduced, effectual reduction manufacturing cost, and can keep the efficiency unchangeable, thereby it all can be antibiotic to realize positive reverse side through all setting up mould proof antibacterial agent layer in the both sides on plastic film layer, and can use at food package bag, the heat preservation inner bag.
