Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0044] Such as Figure 1 ~ Figure 4 As shown, the first content of the present invention: air enters from the opening of the distribution supply main pipe A, passes through the false heat seal b1 from the gap between 2a and 2b and passes through the distribution channel a, from the gap between 2a and 2b, smoothly Entering each space B, as the air flow increases, the space B begins to expand gradually. When the inflation is stopped, the gap between 2a and 2b is automatically adsorbed together due to the special properties of the inner surface of the film itself, plus The effect of air pressure makes the sticking between 2a and 2b tighter, so that the incoming air cannot leak out from B, and realizes the technical invention of film self-adhesive adsorption and one-way anti-leakage function.

[0045] Such as Figure 5 ~ Figure 7 As shown, the se...

Abstract

The invention relates to a functional type self-adhesive film one-way air blocking three-dimensional packing material and a preparation method thereof. The three-dimensional packing material is formed by combing a plurality of layers of functional resin thin films, the functional resin thin films form a space used for storing the gaseous medium including air through hot sealing and folding, and the air and the thin films are combined into the functional type self-adhesive film one-way air blocking three-dimensional packing material. Compared with the prior art, the air three-dimensional packing material of the invention has excellent comprehensive protective properties of extrusion resistance, vibration resistance, falling prevention and buffering, and meanwhile, can be embodied with the functions of light prevention, moisture resistance, electrostatic prevention, electric conduction, wear-resistance, corrosion resistance, rust protection and impressionability, etc.

Description

technical field [0001] The invention relates to a packaging material and a preparation method thereof, in particular to a functional self-adhesive film one-way air barrier that can be applied to precious and fragile products such as electronic products, glassware, precision instruments and meters, and handicrafts, as well as products that require relatively high safety protection performance. Disclosed are three-dimensional packaging materials and a preparation method thereof. Background technique [0002] Packaging is a means to realize commodity value and use value, and a bridge between commodity production and consumption. Green packaging requires packaging materials to save resources, reduce waste, easy to recycle or regenerate, or easy to decompose naturally, not to pollute the environment, and to be beneficial to the health of consumers. While the packaging industry is developing rapidly, it has also become one of the largest polluting and resource-wasting industries....
