Problems solved by technology

During the cutting process, in order to prevent the air column from leaking due to cutting to the air column part, a certain margin needs to be reserved on both sides of the air column bag, generally half the width of the air column; this causes the production process Waste of raw materials in air column bags

Abstract

The invention relates to an air column type protection device. The air column type protection device comprises a plurality of air columns. Every two adjacent air columns are partitioned through a longitudinal heat sealing line. An air inlet part used for filling each air column with air is arranged on the top of the air column. An air inlet is formed in one side of each air inlet part. The air column type protection device is characterized in that at least two transverse heat sealing lines are distributed on each air column in the longitudinal direction, each transverse heat sealing line is provided with a free end, and an air intake channel extending for a preset distance is formed between the free end of each transverse heat sealing line and the corresponding longitudinal heat sealing line. One end of each transverse heat sealing line is connected with the longitudinal heat sealing line on one side of the corresponding air column, and the corresponding air intake channel extending for the preset distance is formed between the free end of each transverse heat sealing line and the longitudinal heat sealing line on the other side of the corresponding air column. Positioning points are arranged on the longitudinal heat sealing lines and correspond to the free ends of the transverse heat sealing lines. The air intake channels are formed between the free ends of the transverse heat sealing lines and the positioning points. The air column type protection device can be folded at any position, and requirements of products in different sizes in the practical packaging process are met.

Description

technical field [0001] The invention relates to an air column type protection device, in particular to an air column type protection device for packaging to protect articles to realize shockproof. Background technique [0002] In the process of product packaging and transportation, in order to prevent collision and shock, most of them are packed in air-filled shockproof bags. The air column bags used in the prior art are formed by connecting several air columns, and the air columns are separated by heat-sealing lines. In addition, sometimes the air column bag needs to be folded into a certain shape during use. At present, a horizontal folding heat-sealing line is set on the position on the air column that needs to be folded, and the air column bag is bent along the folding heat-sealing line to form Three-dimensional bag body. However, there are certain defects in this form of air column bag, which can only be folded at the position where the folding heat sealing line is pr...
