Abstract

The invention discloses a plastic automatic sealing bag with high sealing performance. The plastic automatic sealing bag comprises a square plastic bag and an automatic sealing device. The automatic sealing device comprises a left rubber soft magnetic sheet and a right rubber soft magnetic sheet, the length dimensions and the width dimensions of the left rubber soft magnetic sheet and the length dimensions and the width dimensions of the right rubber soft magnetic sheet are identical to one another, and the left rubber soft magnetic sheet and the right rubber soft magnetic sheet have attracting magnetism; the left rubber soft magnetic sheet is provided with two parallel protruded strips along the length direction, and two grooves which correspond to the two protruded strips are formed in the right rubber soft magnetic sheet along the length direction; left double-sided adhesive and right double-sided adhesive are respectively arranged at the left end of the left rubber soft magnetic sheet and the right end of the right rubber soft magnetic sheet, and the left rubber soft magnetic sheet and the right rubber soft magnetic sheet are respectively fixedly adhered on the upper portion of a left bag sheet and the upper portion of a right bag sheet by the left double-sided adhesive and the right double-sided adhesive. The plastic automatic sealing bag has the advantages that the fastening and opening efficiency can be obviously improved, and strict sealing requirements further can be met owing to the high sealing performance of the plastic automatic sealing bag.

Description

technical field [0001] The invention relates to the technical field of plastic ziplock bags, in particular to a plastic ziplock bag with strong airtightness. Background technique [0002] The self-sealing device of the existing plastic self-sealing bag comprises a self-sealing bag rib and a self-sealing bag groove. Plastic ziplock bags are favored by all walks of life and consumers because of their convenient fastening and opening. However, there are two major defects in this self-sealing device: one is that the fastening and opening efficiency is not high; the other is that due to insufficient sealing, it cannot meet strict sealing requirements. Contents of the invention [0003] The purpose of the present invention is to solve the deficiencies of the prior art and provide a plastic ziplock bag, which can not only significantly improve the fastening and opening efficiency, but also meet strict sealing requirements due to its strong sealing performance. [0004] The tech...
