Inflatable thin film buffer cushion and machining method thereof

Abstract

The invention relates to a buffer cushion and a machining method thereof, in particular to an inflatable thin film buffer cushion and a machining method thereof. According to the technical scheme, the inflatable thin film buffer cushion is characterized in that a second heat-seal line is located at the ends of two layers of inner films, and the ends of the two layers of inner films and adjacent outer films are heat-sealed together through the second heat-seal line. According to the technical scheme, the method comprises the following steps that 1, heat sealing of fourth heat-seal points or heat-seal lines is carried out, and therefore the inner films are partially attached to the outer films; 2, heat sealing of the second heat-seal line is carried out, and the second heat-seal line only enables the two layers of inner films to be bonded with the adjacent outer films together; and 3, heat sealing of other heat-seal lines is carried out. The first step must be carried out firstly, and heat sealing of a first heat-seal line must be carried out after heat sealing of the second heat-seal line. By means of the scheme, the inflatable thin film buffer cushion convenient to machine and low in cost and the machining method of the inflatable thin film buffer cushion are provided.

Description

technical field [0001] The invention relates to a buffer pad and a processing method thereof, in particular to an inflatable film buffer pad and a processing method thereof. Background technique [0002] Existing inflatable film cushions, such as the patent No. 200610067311.5 "Air cushioning body with air-tight air-locking device for sealing body and its manufacturing method" patent on March 13, 2006, the technical solution of this patent is : Including: a continuous sealing body, which contains two outer films and two inner films between the two outer films, and is coated at equal intervals on the side of one inner film facing the other inner film Heat-resistant materials are used to form several heat-resistant joints, which are characterized in that: heat-seal points are applied on the two outer films and below the apexes of the heat-resistant joints, and the heat-seal points connect the adjacent outer films to the inner film; A heat-sealing line is applied on the outer m...

AI Technical Summary

Problems solved by technology

The air buffer of the above technical solution has the following problems: 1. It is necessary to coat heat-resistant materials between the two inner films, which increases the cost; 2. It is necessary to benchmark the heat-resistant materials during production, that is, the position needs to be Alignment, so that the inflation port can be guaranteed to be normal during production; 3. The upper end of the inner membrane is located in the inflation channel. Although there are heat-sealing points, there is also the problem that the inner membrane is folded and cannot be inflated smoothly.
