Manufacturing method of hot-melt sealing inflation shakeproof packaging bag and hot-melt sealing inflation shakeproof packaging bag

Abstract

The invention discloses a manufacturing method of a hot-melt sealing inflation shakeproof packaging bag and the hot-melt sealing inflation shakeproof packaging bag. The hot-melt sealing inflation shakeproof packaging bag comprises a first square hot melt film, a second hot melt film identical with the first hot melt film in shape, and a check valve arranged between the first hot melt film and the second hot melt film. By arranging a U-shaped second hot melt zone, a U-shaped air channel forms a U-shaped air column after inflation, on the one hand, through restrict of hot melt connection, the heights of the two sides of the packaging bag are limited to a certain degree, and thus the space is saved; and on the other hand, the U-shaped air column can form an edge protection zone. By arranging a third hot melt zone, through restrict of hot melt connection likewise, the height of the middle of the packaging bag is limited to a certain degree, and thus the space is saved. By forming air holes in the third hot melt zone, the effect that objects do not go bad or cannot be damaged in a certain period can be ensured.

Description

technical field [0001] The invention relates to the field of bubble packaging manufacturing, in particular to a method for making a heat-melt sealed inflatable shockproof packaging bag and a heat-melt sealed inflatable shockproof packaging bag. Background technique [0002] In the process of transportation, goods generally need good packaging to ensure that the goods are not damaged. For different goods, the packaging also has different requirements. The packaging of fragile items needs to be shockproof, and the packaging of fruits or food often needs to be breathable. , the traditional packaging method is to fill a large amount of soft materials around the items after putting them into a box or box, such as foam, sponge, etc. With the development of society, people also have higher requirements for packaging Therefore, the packaging should not only be based on the safety of shockproof or insurance, but also ensure the convenience of use. Bubble packaging refers to a device...

AI Technical Summary

Problems solved by technology

Bubble packaging refers to a device that forms shockproof bubbles by inflating between two or more layers of plastic film. At present, there are various bubble packaging bags on the market, such as those designed in rolls. The bag wraps the items to achieve the shockproof effect. This kind of packaging is very inconvenient during use and takes time to operate. At the same time, in order to achieve a better shockproof effect, many circles of packaging materials will be wound, which will cause material damage. Waste; Later, some individual packaging bags appeared on the market, composed of multiple air columns and multi-layer inflatable ones. These packaging bags are inflated through a one-way valve device. Sheet valve, this kind of packaging bag also has serious disadvantages, that is, the packaging bag is bulky due to inflation, and at the same time, when transporting commodities such as fruits that need to be ventilated, the packaging bag is easy to cause damage due to the lack of breathing function.
