Abstract

The invention relates to a self-adhesive film air-rejecting three-dimensional packaging material and a manufacturing method thereof. The packaging material is composed of four layers of resin films, including two wider resin films and two narrower resin films. Subpartial heat sealing and a series of folds form multiple spaces that can store air medium, and use the interaction of the film's own viscosity and air pressure to prevent air from leaking out, thus forming a self-contained air medium by air and film. Mucous membranes reject air and three-dimensional packaging materials. Compared with the prior art, the air three-dimensional packaging material of the present invention has excellent comprehensive protection properties such as extrusion resistance, shock resistance, drop resistance and buffering, and can be used as a filling packaging material for articles, as a partition for parts or important parts of articles. It is used for all-round outer packaging of pads and articles.

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...
