Specific implementation mode
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of explosion-proof airtight salivation co-polypropylene film for gas flush packaging, include successively corona layer 1,
Supporting layer 2 and hot sealing layer 3, the supporting layer 2 is interior to disperse fiber 4, the arc top court of the power dispersion fiber 4 equipped with arc-shaped power
To corona layer 1.
This explosion-proof airtight salivation co-polypropylene film from outside to inside successively including corona layer 1, supporting layer 2 and hot sealing layer 3,
Middle corona layer 1 is made by the copolymer of the ethylene and propylene processed through identical corona working power, and thickness is 3-10 microns, preferably
It is 6 microns, the surface tension of such corona layer 1 can promote 20% or more compared to usual commercially available polyacrylic surface tension,
Certain promotion also can be obtained in durability degree simultaneously, to promote the antiknock effect of film entirety；Supporting layer 2 is made by polypropylene,
Thickness is 15-45 microns, preferably 30 microns, can integrally provide film a support force；Hot sealing layer 3 by ethylene, propylene and
The copolymer of butadiene is made, and thickness is 7-15 microns, and preferably 11 microns, such heat-sealing temperature can be down to 104 DEG C hereinafter, big
It is big to have saved energy required when heat-sealing, while the melt viscosity of ethylene-propylene-diene terpolymer is relatively low, is conducive to
Capillary porosity that may be present when filling sealing, ensures the air-tightness of sealing；Arc-shaped, and arc top is additionally provided in supporting layer 2
Disperse fiber 4 towards the power of corona layer 1, when external pressure acts on the certain point on inflation packet surface, power disperses fiber 4 can be right
The external pressure is disperseed, and supporting layer 2 is made integrally to be supported to external pressure.
Preferably, the power dispersion fiber 4 includes that several power disperse arc 5, and the arc bottom of two neighboring power dispersion arc 5 is mutual
Plane residing for connection, at least two power dispersion fibers 4 is vertical with supporting layer 2, and adjacent two power disperse fiber 4 same
Plane, power disperse fiber 4, and power disperses fiber 4 and disperses arc 5 by several power, when external pressure acts on the arc top that power disperses arc 5
The peptizaiton of power can be played when nearby, and dispersion effect is poor when force effect is near the arc bottom that power disperses arc 5, therefore edge
There are at least two power to disperse fiber 4 on the direction vertical with supporting layer 2, and disperse in fiber 4 in adjacent two power, under being located at
The arc bottom of the power dispersion arc 5 of the arc top of the power dispersion arc 5 of the power dispersion fiber 4 of side and the power dispersion fiber 4 being located above is just
It is corresponding, to ensure the power dispersion effect of all sites.
The specific material of power dispersion fiber 4 may be used organic fiber, for example, aramid fiber, Orlon fiber, polyester fiber,
Inorfil, such as glass fibre, carbon can also be used in nylon fiber, vinylon fiber, polypropylene fibre, polyimide fiber
Fiber, boron fibre, whisker, asbestos fibre and metallic fiber.
As shown in Figure 1, one side of the hot sealing layer 3 far from supporting layer 2 is equipped with heat-sealing sticking part 6, the heat-sealing sticking part 6
It is spaced the heat-sealing sawtooth portion 7 being uniformly arranged including several, the cross section in the heat-sealing sawtooth portion 7 is equilateral triangle or isosceles ladder
Shape, is equipped with sawtooth holding section 8 between each two adjacent heat-sealing sawtooth portion 7, the shape of the sawtooth holding section 8, size with
Seal that sawtooth portion 7 is corresponding, and in heat seal process, two films are staggered relatively, at this time the heat-sealing sawtooth portion 7 on a film with it is another
Sawtooth holding section 8 on one film fits, therefore sets the cross section for sealing sawtooth portion 7 to equilateral triangle or isosceles ladder
Shape, in this way in heat-sealing, the patch of smooth film surface during heat-sealing sawtooth portion 7 fits compared with prior art with sawtooth holding section 8
Close with bigger contact area, therefore can be bonded it is even closer, and then improve heat-sealing when yield rate, ensure inflation packet have
Higher air-tightness.
