Air packaging device and production method for same

Abstract

Disclosed is an air packaging device. A space capable of storing air is formed by two thermoplastic films by means of two-time thermoplastic packaging. The air packaging device comprises a plurality of independent hermetic air chambers and a main passage, the main passage is provided with an air inlet, each hermetic air chamber is communicated with the main passage through a one-way valve consisting of two films, and two or more than two one-way valves are mounted in parts of air chambers or all the air chambers. Buffers are added on main portions of the air packaging device, and the size of air columns is decreased on the portions which do not need too much protection, so that the size of the air packaging device can be effectively decreased, and transport cost is reduced. By means of direct forming at a use site of a user, transport space and cost can be greatly reduced, so that the problem of excessively high cost during long-distance transport of packaging materials is solved.

Description

technical field [0001] The invention relates to a three-dimensional air-tight packaging device designed and produced by self-adhesive membrane rejection (one-way valve) technology and a production method thereof. The device can be used in precious and fragile products such as electronic products, glassware, precision instruments, handicrafts, and printing consumables. And various fields with relatively high safety protection performance requirements. The invention is a new type of environmentally friendly packaging material with comprehensive protection properties such as extrusion resistance, vibration resistance, sealing and moisture resistance, drop resistance and buffering. Spacer boards and all-round cushioning packaging for items or directly used in the outer packaging for sales by printing. Background technique [0002] The globalization trend of enterprises has increased the transportation distance of products from the place of production to the place of consumption...

AI Technical Summary

Problems solved by technology

[0007] The disclosed air-packing device of above-mentioned patent application is as figure 1 As shown, the air enters each air chamber 3 through the main channel 1 through the one-way valve 2. The diameters of the air chambers 2 are basically the same, and the inflated body and the maximum pressure they bear are basically the same. When the packaged object falls, All the air chambers are equivalent to plane force, the pressure they can withstand is relatively small, and the cushioning effect is not very ideal

[0008] On the other hand, after the inflation is completed, the size of the object that can be accommodated in its internal space is basically certain. If the volume of the packaged object is too large to be placed in the air packaging device, if the volume of the packaged object is too small, the object In the air-packing device, there will be movement, impact, and breaking of the air-packing device, so that the cushioning protection of the package cannot be realized

For those packaging objects with little difference in volume (such as 14-inch and 15-inch laptops), two sets of production processes and molds are required, which greatly increases the production cost

At the same time, the volume of packaging increases, which increases the cost of transportation. For the current global procurement, production, transportation and sales, it greatly increases the cost of the final product.
