Problems solved by technology

If the force is uniform, the reaction force that the middle part of the plane can withstand after the object falls is relatively the smallest, so the cushioning effect of uniform force is poor, and it is easy to cause local damage
Generally, it is necessary to increase the diameter of the air chamber to enhance the overall cushioning effect, but this increases the overall volume after packaging, thereby increasing the transportation cost

Embodiment Construction

[0033] The air-packing device with multi-stage cushioning of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0034] The primary heat sealing refers to the process of thermally sealing two layers of thermoplastic film and the one-way valve to form a flat bag that can store air. The secondary heat sealing refers to the secondary heat sealing after folding the semi-finished product after the primary heat sealing. The process of plasticizing the thread again to form a three-dimensional bag that can hold objects.

[0035] figure 1 Shown is the schematic diagram of the first embodiment of the air-packing device with multi-stage cushioning of the present invention before the second heat sealing. The double line shows the first heat sealing line formed by the first heat sealing of the abrasive tool. As shown by the arrow in the figure, the air enters the main channel 2 through the air inlet 1, and then enters each sealed ai...

Abstract

The invention discloses a multi-buffer air packing device. In the device, two layers of thermoplastic films are subjected to two times of thermal plastic sealing to form a three-dimensional packing body capable of sealing the air, the packing body comprises a plurality of independent sealed air chambers and a main channel with an air inlet, each sealed air chamber is communicated with the main channel through a one-way valve formed by two layers of films, the sealing chambers have turning points, the packing body is divided into a main bearing face and a lateral bearing face by a turning point line formed by the turning points, the diameter of the middle part of the sealed air chamber of the main bearing face formed after inflation is smaller than the diameters of the sealed air chambers on two sides. In the air packing device of the invention, higher air chambers, when a packed object falling onto the ground is impacted, contact the ground first and then the lower air chambers in the middle contact the ground to produce a secondary buffering effect, so the impact of the packed object is relieved considerably and the impact performance of the packing device is improved. Compared with packing devices of the same volume, the multi-buffer air packing device has much higher impact performance.

Description

Technical field [0001] The invention relates to a three-dimensional air-sealed packaging device designed and produced by using self-adhesive film rejection (one-way valve) technology. The device can be used in electronic products, glassware, precision instruments, handicrafts, printing consumables and other precious and fragile products, as well as safety protection performance Various fields with higher requirements. The present invention is a new type of environmental protection packaging material with comprehensive protection properties such as extrusion resistance, vibration resistance, sealing moisture resistance, fall resistance and buffering. It can be used as the protection and filling of articles during transportation, and the partial or important parts of articles Septa and items are used in all-round cushioning packaging or directly used in sales packaging through printing. Background technique [0002] The globalization trend of enterprises has increased the transpor...
