Inflating bag sealed with binding base material and manufacture process for same

Abstract

The invention discloses an inflating bag sealed with a binding base material and a manufacture process for the same. The inflating bag is characterized by comprising an inner bag, an outer bag and the binding base material, an air valve capable of inflating is arranged on the inner bag made of a co-extruded film, the outer bag is made of polypropylene woven base fabric, polypropylene woven base fabric composite kraft paper or pure kraft paper and is provided with an exposed opening capable of leading the air valve on the inner bag to penetrate through, and the two ends of the inflating bag are sealed with the binding base material. Internal pressure of the inflating bag in use can be doubled as compared with that of an inflating bag made by means of sewing. Besides, the inflating bag adopts one-time binding technology so that binding is cured after sealing, and when a container is applied, the binding cannot be melted or embrittled at the external extreme high temperature or low temperature of the container, so that proper binding property is kept.

Description

technical field [0001] The invention relates to the field technology of inflatable bags, in particular to an inflatable bag sealed with an adhesive base material. Background technique [0002] With the rapid development of the logistics industry at home and abroad and people's increasing attention to the packaging of goods, polypropylene woven air bags, polypropylene woven base fabric composite kraft paper air bags, and pure kraft paper air bags (referred to as air bags) are becoming more and more popular among cargo owners and customers. Logistics companies use it as an essential packaging material. [0003] With the continuous use of the air bag, in order to ensure the pressure of the air bag and the increase of the internal pressure, improve the safety of the use of the air bag, reduce the cost of raw materials and increase the production capacity. On the basis of the traditional bag sealing method and sewing method, the traditional air bag often increases the thickness ...

AI Technical Summary

Problems solved by technology

On the basis of the traditional bag sealing method and sewing method, the traditional air bag often increases the thickness of the material of the air bag or adopts the multi-fold sewing method, which increases the production cost and process of each air bag to a certain extent. complexity, and the effect still cannot achieve safety and feasibility in real practical use
