Film.The novel toughening type air permeable waterproof laminated film of the utility model has waterproof and breathable, the strong advantage not easy to break of toughness.
In order to solve the above technical problems, the technical solution adopted in the utility model is.
A kind of toughening type air permeable waterproof laminated film, including upper layer, chitosan anti-bacteria layer, the first PE ventilative film layer, second
Breathe freely film layer, the 3rd PE of PE breathes freely film layer, nanometer silver antimicrobial layer and lower layer, and successively compound in order, it is poly- that shell is pasted on the upper layer
Sugared antibiotic layer, the chitosan anti-bacteria layer paste the first PE and breathe freely film layer, and the first PE breathes freely compound 2nd PE of film layer
Ventilative film layer, the ventilative film layer of ventilative compound 3rd PE of film layer of the 2nd PE, the ventilative film layer composite nano silver of the 3rd PE are anti-
Bacterium layer, the compound lower layer of nanometer silver antimicrobial layer.
The antibacterial agent of a kind of preferred embodiment of the utility model, the chitosan anti-bacteria layer addition is carboxymethyl chitosan.
Further, the nanometer silver antimicrobial layer can also add nano zine oxide antibacterial granule.
Further, the 2nd PE breathes freely, and film layer is interior to add nano-calcium carbonate particles.
Further, the 2nd PE breathe freely film layer in addition nano-calcium carbonate particles with a thickness of 16-20 μm.
Further, the first PE breathe freely film layer and the 3rd PE breathe freely film layer with a thickness of 5-10 μm.
Further, the overall thickness of the film is 60-100 μm.
Another preferred embodiment of the utility model, the upper layer and the lower layer are Biaxially oriented polypropylene layer, thickness
It is mutually all 5-12 μm.
The beneficial effects of the utility model.
(1) the utility model antibacterial film adds nano-sized carbon using the ventilative film layer of three layers of PE and in the ventilative film layer of middle layer PE
Sour calcium particle has and can breathe freely but waterproof effect, while situations such as be not in fracture, junk.
(2) the utility model antibacterial film using upper and lower level Biaxially oriented polypropylene layer cooperation air-permeable layer and adds a variety of anti-
The structure of the antibiotic layer of bacterium particle effectively extends fresh keeping time, and the antibacterial effect time is long.
