Two leaching membrane layers (7), polyethylene layer offer multiple five-pointed star holes, and polyethylene layer passes through filling glue and body paper in five-pointed star hole
Layer and the second leaching membrane layer bond.
Wherein, polyacrylic acid clathrum is fused by several root polypropylene acid fiber crossovers, polyacrylic acid clathrum
Thickness is 0.5~8 μm, such as 0.5 μm, 1 μm, 2 μm, 3 μm, 4 μm, 5 μm, 6 μm, 7 μm or 8 μm.
Wherein, the thickness of nonwoven layer is 5~8 μm, such as 5 μm, 5.5 μm, 6 μm, 6.5 μm, 7 μm or 8 μm.
Wherein, the first adhesive layer is aqueous polyacrylamide coating layer, and the thickness of the first adhesive layer is 3~8 μm, such as can be
3 μm, 4 μm, 5 μm, 6 μm, 7 μm or 8 μm.
Wherein, the thickness of the first leaching membrane layer and the second leaching membrane layer is 3~4 μm, such as can be 3.1 μm, 3.2 μm, 3.3 μ
M, 3.5 μm, 3.8 μm or 4 μm.
Wherein, the thickness of polyethylene layer be 5~6 μm, such as can be 5.1 μm, 5.2 μm, 5.3 μm, 5.5 μm, 5.8 μm or

The beneficial effects of the utility model：Polyacrylic acid clathrum in the utility model not only has good intensity, but also
With good flexibility, polyethylene layer has good flexibility, and polyethylene layer offers multiple five-pointed star holes, convenient glue
It is diffused into original paper layer and the second leaching membrane layer, improves the adhesion strength of polyethylene layer and original paper layer and the second leaching membrane layer, solve
The problem of intensity of leaching membrane paper and poor flexibility.The leaching membrane paper of the utility model has good intensity and flexibility.
Description of the drawings
Fig. 1 is the structure diagram of the leaching membrane paper of the utility model.
Reference numeral is as follows：1- original paper layers, 2- polyacrylic acid clathrum, 3- nonwoven layers, the first adhesive layers of 4-, 5- first
Leaching membrane layer, 6- polyethylene layers, 61- five-pointed stars hole, the second leaching membrane layers of 7-.
Specific embodiment
The leaching membrane paper of the utility model is suitable for packaging material.
The technical solution of the utility model is further illustrated below in conjunction with Fig. 1 and by specific embodiment.
The leaching membrane paper of the utility model, including original paper layer 1, the one side of original paper layer 1 is disposed with polypropylene from the inside to the outside
Sour clathrum 2, nonwoven layer 3, the first adhesive layer 4 and the first leaching membrane layer 5, the opposite side of original paper layer 1 are set gradually from the inside to the outside
There is 6 and second leaching membrane layer 7 of polyethylene layer, polyethylene layer 6 offers multiple five-pointed star holes 61, and polyethylene layer 6 is by five-pointed star
Filling glue is bonded with 1 and second leaching membrane layer 7 of original paper layer in hole 61.
