Air packing device having multilevel buffers

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-tight packaging device designed and produced using self-adhesive film rejection (one-way valve) technology. The device can be used in precious and fragile products such as electronic products, glassware, precision instruments, handicrafts, printing consumables, etc., and has safety protection performance. Various fields with relatively high 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, resulting in the rapid d...

AI Technical Summary

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
