Anti-fake packing tape

Abstract

The invention relates to tape, in particular to anti-fake packing tape. The anti-fake packing tape comprises a transparent base material layer, a gluing layer is arranged on the lower portion of the transparent base material layer, and a printing ink printing layer and an additive transparent base material layer are sequentially arranged between the transparent base material layer and the gluing layer from top to bottom. Coloring agent line layers are arranged at the two sides of the gluing layer in the width direction respectively, and a strip-shaped groove in the length direction is formed in the middle of the gluing layer and filled with paraffin mixed with a coloring agent; before being used, the anti-fake packing tape is heated by a blower. As the two anti-fake modes including the dyeing agent line layer and the strip-shaped groove are used in combination, it is ensured to the maximum that a consumer knows whether packing tape is torn off by other people in advance or not at the first time.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to an anti-counterfeit sealing adhesive tape. Background technique [0002] Sealing tape, also known as packaging tape, is based on BOPP biaxially stretched polypropylene film or PET polyester film substrate, and is evenly coated with pressure-sensitive latex after heating to form a glue ranging from 8 microns to 28 microns. After the original film is treated with high-voltage corona, the surface of one side is rough, and then glue is applied on it to form a master roll, and then cut into small rolls of different specifications by a slitting machine, which is what we use every day. tape off. At present, products in various industries are packaged in boxes, and the boxes are usually sealed with sealing tape, which has the advantages of beautiful packaging and cost saving. [0003] At present, anti-counterfeiting tapes are used in packaging, but the anti-counterfeiting tapes used today are all eq...

AI Technical Summary

Problems solved by technology

[0003] At present, anti-counterfeiting tapes are used in packaging, but the anti-counterfeiting tapes used today are all equipped with an ink printing layer under the transparent substrate as the anti-counterfeiting layer, and then the adhesive layer is immediately below. The anti-counterfeiting pattern on the printed layer will disappear soon, and its anti-counterfeiting effect cannot be identified, and even its anti-counterfeiting function will be lost

[0004] At the same time, the traditional sealing tape has almost no anti-counterfeiting performance. When it is opened and then pasted again, there is hardly any trace of being opened on the surface, thus providing an opportunity for unscrupulous merchants
