Abstract

The utility model discloses an antibacterial food packaging film material. A biaxially-oriented Polypropylene (BOPP) film layer, a chitosan antibacterial film layer, a polyethylene film layer and a polyethylene film heat-sealing layer are orderly arranged on the material from the outside to the inside. By combining with the performance advantages of the layers, the food packaging film material has good mechanical property and antibacterial property, also can achieve direct printing, has environment protection characteristics, and can be applied to the fields of food packaging films and food packaging bags.

Description

A kind of antibacterial food packaging film material

Technical field

The utility model relates to a kind of packaging for foodstuff membrane material, relates in particular to a kind of packaging for foodstuff membrane material with antibacterial effect.

Background technology

Packaging material for food directly and packaging Food Contact, because it is extensively paid attention to the safety of food being exerted an influence and then affecting human-body safety.Existing packaging for foodstuff membrane material generally adopts Biaxially oriented polypropylene, aluminium foil and polyethylene structure, though can meet the requirement of mechanical property, but its antibiotic property is poor, keeping quality to some Special food is poor, so exploitation one both can guarantee mechanical property, the packaging material that can realize again antibiotic property are of great value.

Utility model content

In view of the defect that prior art exists, the purpose of this utility model is to provide a kind ofly to be had excellent mechanical performances, antibiotic property, not to be detrimental to health, the environmental protection food package film that can directly print.

For achieving the above object, the technical solution of the utility model provides a kind of antibacterial food packaging film material.This material is followed successively by BOPP thin layer, chitosan anti-bacteria rete, polyethylene film layer, polyethylene film hot sealing layer from outside to inside.Wherein BOPP thin layer is extexine, between chitosan anti-bacteria rete and polyethylene film hot sealing layer, is film layer, and polyethylene film hot sealing layer is bottom.

Further, described BOPP thin layer thickness is 0.015-0.03mm, and the thickness of chitosan anti-bacteria rete is 0.1-0.3mm, and the thickness of polyethylene film layer is that 0.1-0.3mm polyethylene film hot sealing layer thickness is 0.02-0.05mm.

Further, described BOPP thin layer can adopt sided corona treatment, can directly print on surface.

Further, between this membrane material multilayer, adopt binder bonding.

Further, described chitosan anti-bacteria rete be with shitosan or chitosan derivatives as CMC, after shitosan quaternary amine etc. and polyethylene blend by extruding the rete obtaining.Wherein shitosan or the chitosan derivatives mass fraction in film is between 50%-80%.

The utility model combines the antibiotic property of shitosan and the mechanical property of polyethylene film, makes material can be applicable to packaging for foodstuff, especially to the antibacterial packaging for foodstuff field having higher requirements.Meanwhile, can make this composite membrane directly print by sided corona treatment top layer BOPP film, reduce treatment process.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model one example.

The specific embodiment

For technological means, constituted mode that the utility model is realized are easier to understand, below in conjunction with drawings and Examples, the technical solution of the utility model is further explained, but following content is not used in restriction protection domain of the present utility model.

With reference to Fig. 1, a kind of antibacterial food packaging film of the present embodiment material, is followed successively by BOPP thin layer 1, chitosan anti-bacteria rete 2, polyethylene film layer 3, polyethylene film hot sealing layer 4.Wherein BOPP thin layer 1 thickness is that 0.018mm, chitosan anti-bacteria rete 2 thickness are that 0.2mm, polyethylene film layer 3 thickness are that 0.2mm, polyethylene film hot sealing layer 4 thickness are 0.04mm.

Above a kind of preferred embodiment of the present utility model is done to detailed introduction.The described specific embodiment is just for helping to understand core concept of the present utility model.It should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle, can also carry out some improvement and modification to the utility model, these improvement and modification also belong to the protection domain of the utility model claim.
