Description

Technical Field

[0001] This utility model relates to the field of packaging equipment technology, specifically to an air column cushioning packaging. Background Technology

[0002] In logistics and transportation, air column cushioning packaging is increasingly widely used due to its environmental friendliness and effective protection of goods, playing a significant role in reducing product breakage rates. However, air column cushioning packaging is mostly made of several layers of film, and for products with sharp corners, such as televisions, existing air column cushioning packaging often fails to pass corner drop tests. While the side-mounted hammock-style cushioning structure disclosed in the comparative document can utilize the space within the air column to suspend items and reduce swaying through fixing plates to achieve cushioning protection, this structure focuses on overall cushioning and fixation of the item, lacking specific protection for sharp corners. It cannot adequately address the problem of sharp corners directly contacting the corners of the air column bag, causing corner drop tests to fail.

[0003] Meanwhile, existing air column cushioning packaging lacks effective solutions in its structural design for cleverly utilizing the air column structure to protect the sharp corners of products. Most simply increase the number of air columns or adjust their arrangement to enhance cushioning, failing to precisely optimize the design for the specific sharp corners of the product, resulting in poor protection in corner drop tests. Utility Model Content

[0004] The purpose of this invention is to provide an air column cushioning packaging to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an air column buffer package, comprising two films, with multiple air columns formed between the two films by a hot melt molding line and inflation. One end of the two films has a main inflation channel formed by the hot melt molding line. The main inflation channel is connected to the multiple air columns through multiple air valves and multiple inflation slots. A heat-sealing molding area is pre-set between the upper part of the air columns after folding and cutting. The heat-sealing molding area consists of a first molding area, a second molding area, and a third molding area. The air columns are reduced in size by hot pressing through the molding line, leaving space to form an accommodating space between the two films.

[0006] As a preferred embodiment of this utility model: the hot melt molding line includes a first side sealing line and a second side sealing line. The first side sealing line and the second side sealing line do not seal to the bottom of the air column after folding and cutting, leaving a size similar to the bottom node size unsealed. The corner of the inflated film will form an uninflated triangular opening.

[0007] As a preferred embodiment of this utility model: the first molding area, the second molding area and the third molding area of ​​the heat-sealing molding area are dot, line or pattern molding areas, and the heat-sealing molding area reduces the air column of the adjacent area, leaving space and forming an accommodating space.

[0008] Compared with the prior art, the beneficial effects of this utility model are:

[0009] 1) The air column cushioning packaging of this utility model has a heat-sealing molding area between the two films after the two films are folded in half. When the films are folded in half to form an accommodating space, the air column at the heat-sealing molding area shrinks and supports, forming a triangular opening with the first side seal and the second side seal. This structural design can avoid the corner of the air column bag from directly contacting the corner of the product to be protected, forming a suspended design. It accurately solves the problem that products with sharp corners are difficult to pass the corner drop test, providing more targeted cushioning protection for the product and significantly improving the protective performance of the air column cushioning packaging for products with special shapes.

[0010] 2) By setting up a heat-sealing molding zone, this utility model can also achieve exclusive protection for the sharp corners of the product by adjusting the structure of specific air columns while ensuring the normal inflation and cushioning function of the air columns. It not only utilizes the cushioning characteristics of the air columns themselves, but also optimizes the protection effect through a unique structural design. This significantly improves the structural rationality and protection accuracy of the air column cushioning packaging, better meeting the market demand for cushioning packaging for products with sharp corners.

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example

[0016] Please see Figure 1-2 This utility model provides a technical solution: an air column buffer package, including two films 100, with multiple air columns 110 formed between the two films 100 by a hot melt molding line and inflation. One end of the two films 100 has a main inflation channel 140 formed by the hot melt molding line. The main inflation channel 140 is connected to the multiple air columns 110 through multiple air valves 141 and multiple inflation grooves 142. A heat-sealing molding area 300 is pre-set between the upper part of the air columns 110 after folding and cutting. The heat-sealing molding area 300 is composed of a first molding area 310, a second molding area 320 and a third molding area 330. The air columns 110 are reduced in size by hot pressing through the molding line, leaving space to form an accommodating space 200 between the two films 100.

[0017] Specifically, two films 100 are first heat-sealed to form multiple air columns 110. Some of the air columns 110 or one air column 110 located on the folded edge are pre-set with a first molding area 310, a second molding area 320 and a third molding area 330. The two films 100 are folded and heat-sealed to form an accommodating space 200. Then, the two films 100 are folded and heat-sealed together using the first side sealing line 120 and the second side sealing line 130 to form a triangular opening 400. The triangular opening 400 allows the sharp corners of the product to be suspended in the air, avoiding direct contact with the corners of the air column bag. In scenarios such as corner drop tests, it effectively buffers the impact force and protects the product.

[0018] In this embodiment: the hot melt molding line includes a first side sealing line 120 and a second side sealing line 130. The first side sealing line 120 and the second side sealing line 130 do not seal to the bottom of the air column 110 after folding and cutting, leaving a size similar to the bottom node size unsealed. The part of the inflated membrane 100 corner will form an uninflated triangular opening 400.

[0019] Specifically, the triangular opening 400 formed after the membrane 100 is folded in half and inflated can be adapted to the shape and position of the product's sharp corners, ensuring that the product's sharp corners are stably suspended within the triangular opening 400. In corner drop tests or actual transportation, the product can always receive effective cushioning protection, improving the accuracy and stability of the air column cushioning packaging in protecting the product's sharp corners.

[0020] In this embodiment: the first molding area 310, the second molding area 320 and the third molding area 330 of the heat-sealing molding area 300 are dot, line or pattern molding areas, and the heat-sealing molding area 300 reduces the size of the air column 110 in the adjacent area, leaving space and forming the accommodating space 200.

[0021] Specifically, by controlling the length of the folded film 100, and in conjunction with the position and length of the first side seal 120 and the second side seal 130, the packaging scheme can form a semi-enclosed or fully enclosed package. Of course, it can also be a package with a separate triangular opening 400, which increases the practicality of the package.

[0022] The contents not described in detail in this description are existing technologies known to those skilled in the art. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
