Problems solved by technology

Since this one-way valve is formed by four-layer film heat sealing, and the main channel is formed by two layers of thermoplastic film, the one-way valve and the main channel can only be arranged on one side end of the airtight air chamber 4, when folded twice When the U-shaped sleeve is formed by plastic sealing, in order to pack and inflate normally, the height of the two legs of the U-shaped sleeve is at least the height of a one-way valve, and for many objects that are not very large, the height of the two legs of the U-shaped sleeve The height can meet the needs without the height of a one-way valve. In this way, we still use this kind of packaging to invisibly produce the problem of excessive packaging, and at the same time, increase the cost of packaging. They are all connected. After inflation, due to uneven air reception, there may be a potential risk of air leakage; in addition, because the outlet preset point 5 of the one-way valve is similar to a smiley face, the height of the one-way valve is basically fixed.

Embodiment Construction

[0029] The air-packing device with a horizontal air valve of the present invention will be further described below in conjunction with the drawings and specific embodiments.

[0030] One-time heat sealing refers to the process of forming a flat bag that can store air by heat-sealing two layers of thermoplastic film and a one-way valve. The process of thermoforming again to form a three-dimensional bag that can hold objects.

[0031] image 3 It is an embodiment of the air-packing device with a horizontal air valve of the present invention, and figure 1 The difference of the packaging device is that it uses a horizontal air valve, such as image 3 As shown, the check valve outlet preset point 35a is a long horizontal line segment, and the preset point 35b is a short horizontal line segment. The preset points 35a and 35b are alternately set to form a horizontal discontinuous straight line 35, and the discontinuous straight line 35 is in each There are two discontinuities in t...

Abstract

The invention relates to an air package device with a transverse air valve. A three-dimensional package body capable of sealing air is formed by two layers of thermoplastic films through secondary thermoplastic sealing, and the air package device comprises a plurality of independent sealing air chambers and a main passage, wherein the main passage is provided with an air inlet, each sealing air chamber is communicated with the main passage through a one-way valve air inlet at an air inlet sealing line part of the one-way valve formed by the two layers of one-way valve films, a plurality of outlet pre-setting points are arranged at the outlet of the one-way valve, the pre-setting points of the outlet of the one-way valve are discontinuous straight lines, and broken points in the middle of the straight lines provide air outlet passages for each one-way valve. The air package device of the invention can reduce the height of the one-way valve films because of the adoption of the transverse air valve in one aspect, and greatly save the cost of the one-way valve films. In addition, the universality of the transverse air value is high, and unlike the traditional one-way valve which needs to correspondingly use one mold according to the diameter of the air chambers, the package devices of air chambers in various widths can use one set of one-way valve mold, thus the cost of the mold is reduced.

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...
