Embodiment Construction
[0033] Combine below figure 1 , figure 2 , image 3, Figure 4 , Figure 5 The self-adhesive air-repelling three-dimensional packaging material and its manufacturing method are further described.
[0034] 1. As long as there are four layers of resin film, using the principle of automatic adsorption of self-adhesive film and the barrier properties of special high-temperature resistant anti-stick printing barrier device, it can be produced through a series of simple local heat-sealing and bonding of special special-purpose heat-sealing equipment A series of related products from mucous membrane repelling air three-dimensional packaging materials.
[0035] Such as Figure 4 As shown, take two polyethylene films of comparable size, one is composed of two narrower polyethylene self-adhesive films with mutual self-absorption, and two wider resin films are the first layer of resin film 1, the second Four layers of resin films 3 are respectively placed on the upper and lower su...
