Problems solved by technology

[0003] The air-packing materials mentioned above also have traditional primitive methods, such as balloons, which are tied with strings after inflation to prevent air leakage, and a series of complex valves such as so-called stop valves, safety valves, and mechanical valves. Or plugs, etc., they have a certain one-sidedness and inconvenience in actual production and operation

Embodiment Construction

[0033] 1. As long as there are four layers of resin film, using the principle of automatic adsorption of self-adhesive film and the barrier characteristics 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.

[0034] Such as Figure 4As shown, take two polyethylene films of considerable size, one is composed of two layers of narrower polyethylene self-adhesive films with mutual self-absorption, and two wider resin films 1, 3 are placed on the upper and lower surfaces respectively. Resin film 2 is placed in the middle layer, of which 2a is partially equipped with a special high temperature resistant anti-adhesive printing barrier device d on the inner surface, which has higher requirements on the raw material performance index of ...

Abstract

An air-isolated 3D packing material with high resistance to squeeze, vibration and impact and excellent buffering effect is prepared from two thicker films and two narrower films through local heat sealing several times and folding several times to form multiple chambers containing air.

Description

technical field [0001] The invention relates to a three-dimensional packaging material that uses a self-adhesive film to reject air, and can be used in various fields such as electronic products, glassware, precision instruments and meters, handicrafts and other precious and fragile products and relatively high safety protection performance. Background technique [0002] Using traditional packaging materials, such as foamed plastic, EPE, paper and hard plastic, etc., it is often difficult to provide items with high safety protection performance requirements. However, air has been used as the cheapest and environmentally friendly packaging medium. When air and film are combined to form packaging materials, it has incomparable advantages in previous packaging materials, such as extrusion resistance, shock resistance, drop resistance and cushioning. Excellent comprehensive protection performance. [0003] The air-packing materials mentioned above also have traditional primitiv...
