The utility model realizes by the following technical solutions:
Biaxial stretching film, it is characterised in that: be followed successively by from down to up polyvinyl resin layer, the first nylon layer, evoh layer and
Polypropylene resin layer, described polyvinyl resin layer, the first nylon layer, evoh layer and polypropylene resin layer form through biaxial tension
Type, described polypropylene resin layer is provided with antibiotic layer, and described antibiotic layer is jointly extruded with polypropylene resin layer and formed.
The thickness of described biaxial stretching film is 40-50 μm.
The thickness of described polyvinyl resin layer is 18-25 μm.
The thickness of described evoh layer is 5-8 μm.
The thickness of described polypropylene resin layer is 12-15 μm.
Being compounded with the second nylon layer through biaxial tension on described antibiotic layer, the second nylon layer is that top layer is through sided corona treatment
Second nylon layer.
The utility model compared with prior art, has an advantage in that:
1st, the utility model uses and is followed successively by polyvinyl resin layer, the first nylon layer, evoh layer and polypropylene from down to up
Resin bed, it is ensured that physical stability is good, mechanical strength is high, air-tightness is preferable, transparency and the spy such as glossiness is higher, tough and hard wear resistant
Point.
2nd, the utility model uses described polypropylene resin layer to be provided with antibiotic layer, described antibiotic layer and polypropylene resin layer
Common extrusion forms, and is additionally arranged antibacterial functions, can effectively suppress growing of bacterium.
3rd, the utility model uses and is compounded with the second nylon layer through biaxial tension on described antibiotic layer, and the second nylon layer is
Top layer, through the second nylon layer of sided corona treatment, is possible to prevent electrostatic, improves security.
