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 buffer effect of uniform force is poor and it is easy to cause local damage

Embodiment Construction

[0036] The air-packing device of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0037] Primary plastic sealing refers to the process of sealing two layers of thermoplastic film and one-way valve to form a flat package that can store air. Secondary plastic sealing refers to folding the semi-finished product after primary plastic sealing and sealing it again along the secondary plastic sealing line. The process of forming a three-dimensional cushioning bag that can hold objects.

[0038] figure 2 It is a schematic diagram of the first embodiment of the air-packing device of the present invention before secondary plastic sealing. It is different from the prior art in that first, the main diameters of the air chambers 3a on both sides are the same and larger than the middle air chamber The main diameter of 3b; second, two check valves 2 are connected to the upper part of the air chamber 3a on both sides and the ...

Abstract

The invention relates to an air packing device. Two layers of thermoplastic films form a space which can store air through thermoplastic process in two steps, and the space comprises a plurality of independent airproof air chambers and a main channel, wherein the main channel is provided with an air inlet, and each airproof air chamber is communicated with the main channel by a check valve formed by two layers of films. The air packing device is characterized in that the main diameters of the airproof air chambers are different. The invention can greatly reduce the transportation space and the transportation cost by a method of direct forming at the using site of a user, thereby solving the problem of overhigh cost due to the long-distance transportation of packing material. The air packing device is additionally provided with the buffering at the major parts and is effectively reduced in the volume by reducing air columns at a plurality of parts that do not need more protections, thereby reducing the transportation cost.

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, which can be used in electronic products, glassware, precision instruments, handicrafts, printing consumables and other precious and fragile products and safety protection performance requirements High variety of fields. 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 development of the demand for...
