Multi-identification-code temperature-variation-prevention safety bag

Abstract

The invention relates to plastic products, in particular to a multi-identification-code temperature-variation-prevention safety bag. A bag body of the safety bag is composed of a left connecting bag body and a right connecting bag body which are connected through an easily-torn line; each connecting bag body is printed with identification codes and an information table, an antitheft seal side is connected to a bag opening of the bag body in a heat seal manner, the inner side of the antitheft seal side is coated with functional ink, the functional ink is in parallel strip distribution, the strip ink on the upper side and the lower side is breakage-proof ink, the strip ink in the middle is temperature-variation-prevention ink, the position, corresponding to the antitheft seal side, of the other side of the bag body is a gluing area, the inner side of the gluing area is coated with glue, and covered with an aluminum foil pad, and a stub area is connected to the position above the gluing area through the easily-torn line and is printed with the identification codes. The manufactured safety bag is provided with the multiple identifications, the temperature-variation-prevention performance is achieved, and the beneficial effects of good sealing performance and good safety are achieved.

Description

technical field [0001] The invention relates to a plastic product, in particular to a multi-identification code anti-temperature change safety bag. Background technique [0002] Although the commonly used hot-melt pressure-sensitive adhesives currently used for plastic bag sealing have the advantages of strong adhesion, they generally have the problem of insufficient temperature resistance. The heat-deformable anti-counterfeiting film is a kind of anti-counterfeiting film made of heat-deformable ink, which is usually bonded to the plastic bag by heat sealing or ultrasonic welding. It is irreversible, so as to remind the user that the items in the plastic bag are at risk of being replaced or tampered with, but there is still a chance to bypass the anti-counterfeiting film and tamper or exchange the items in the bag without destroying the heat-transformable anti-counterfeiting film; In addition, because the bag itself has no unique identification code for the items in the bag...
