Self adhesion vacuum storage bag

Abstract

The invention discloses a self adhesion vacuum storage bag. A bag body (1) is closed and formed by welding four edges with a high frequency fuse machine; two openings are formed in two ends of the surface of the bag body (1); one opening is an object placing port ( 4), and the other opening is a compression exhausting venting port (5); the object placing port (4) is provided with a polyethylene sizing combining plate I (2); the compression exhausting venting port (5) is provided with a polyethylene sizing combining plate II (3); an opening line is arranged at the center of each polyethylene sizing combining plate; the self adhesion vacuum storage bag is characterized in that the polyethylene sizing combining plate I (2) and the polyethylene sizing combining plate II (3) are sized, welded and formed with the set opening of the bag body (1) by the high frequency fuse machine. According to the invention, the surface of the bag body is lustrous and easy to tidy and clean, the bag body is made of a durable high temperature-resistant low temperature-resistant OPP durable high-intensity adhesion sheet, and can be durably adhered at 30 DEG C below zero and 150 DEG C, the adhesion strength can last for plural years, and repeated use is realized. The storage bag is independently suspended and is convenient to suspend and store.

Description

technical field [0001] The invention relates to a vacuum storage bag with the function of bonding and holding air for a long time, in particular to a vacuum storage bag with the functions of repeated use and repeated repair. Background technique [0002] A storage bag that uses compressed vacuum or evacuation to store items for a long time. The vacuum can protect daily food for a long time. It is generally aimed at the bulky daily items and food in family life, such as clothing, quilts, blankets, and fluff. , fruits, vegetables, etc.; because the items are stored in a compressed vacuum or evacuated, the original volume is reduced to create a greater space utilization value for the items, and it can be completely isolated from the outside air, completely preventing the items from being damaged by the weather, environment and The relationship between humidity and temperature can cause aging, oxidation or bacteria breeding due to moisture; therefore, vacuum storage bags are fav...

Problems solved by technology

[0003] The popular self-adhesive sealed vacuum storage bag and electrostatic compression storage bag with electrostatic isolation film, the patent number 200620103947.6 is a vacuum storage bag made of polyvinyl chloride (pvc), which is a kind of plastic The main component of the added plasticizer and anti-aging agent is DOP. The main auxiliary materials of the plasticizer are toxic. At about 50 degrees, hydrogen chloride gas will be slowly decomposed, and hydrochloric acid and other harmful substances will be produced during the combustion process. , where chlorine itself is a toxic substance, because this kind of self-adhesive sealed bag completely relies on the self-adhesive effect of the material characteristics of the bright PVC layer to complete its sealing function; the bright PVC layer should have absolute bright surface characteristics, There must be no scratches, abrasions, sand, dust or lint, otherwise it will inevitably lose its self-adhesive properties, which is its biggest lack of practicality
