See Fig. 1, the basic structure of antitheft tamper-evident adhesive tape is identical with existing adhesive tape, and what the upper surface of basement membrane 2 (A face) was coated with is adherent layer 1 material of using always, is used for convenient the use and becomes the web-like commodity with adhesive tape product, also makes in the packing use, does not contact the article adhesion with other.The bottom surface is the non-drying glue layer 6 of modified soluble pressure sensitive adhesive, when being used for packing joint sealing or binding and packing body, tightly sticks at packing material.Make etch layer 3 the going to the bottom of basement membrane 2 (B face) by etching and be coated with easily separated layer 4 back again with containing the label layer 5 that anti-counterfeiting heat-sensitive variable color, printing ink are printed with literal or other pattern, form the peculiar identification icon of product.Between etch layer 3 and non-drying glue layer 6, make the easily separated layer 4 of one deck, and directly at the literal color identification layer 5 of easily separated layer bottom surface printed product, again non-drying glue layer 6 is produced on the label layer 5; Easily separated layer 4 has stable cohesive force with basement membrane 2, but owing to be provided with the deep mixed etch layer that causes 3 at the B of basement membrane face, thereby the each point bonding force is inequality, but less than the cohesive force of the modification non-drying glue layer 6 that directly is bonded as one with the tr face, with label layer 4 and 6 cohesive forces that have the phase commute to peel off of non-drying glue layer; Like this, when adopting change temperature or humidity to retract tape, easily separated layer 4 and basement membrane 2 break away from the non-drying glue layer 6 that is bonded as one with label layer 5 by the size of etched depth bonding force, being label layer 5 stays the wrapping body surface with non-drying glue layer 6 because of what the etch layer 3 etched depths being brought to of becoming that irregular destroyed label layer 5 has had on the film, stays vestige clearly; Whether naked eyes can check this case (bag) to open;
The concrete technological process of production method of the present invention is:
1) film of former manufacturer production is the single face corona after corona detects, and tackles another facial mask and carries out corona or carry out etch processes by demanding party's requirement;
2) for guaranteeing that film cleaning surfaces mass concentration is that the 5%-10% sodium hydroxide solution cleans film, remove surface impurity, increase the sticking power of easily separated layer of false proof, antitheft material, again through clear water rinsing, oven dry, it is standby to destatic rolling;
3) be coated with Fabric with forme and protect and need not corrode partly, with the 20%-35% sodium hydroxide solution film is carried out etching, make the B face of film form male and female face clean water basin rinsing after removing protective layer again, oven dry checks rolling standby;
4) be coated with the easily separated layer of Fabric with forme, viscosity mm≤1.5 are held in check;
5) can in water color ink, add material such as have temperature-sensitive, radium-shine, luminous by demanding party's requirement, in order to printing the tape that possesses various anti-counterfeiting performances;
6) with forme printing photo-electric tracing line, oven dry rolling;
7) be coated with adherent layer, check, oven dry, rolling;
8) stamp demanding party literal, pattern, oven dry, check aberration by demanding party's requirement with multicolour press with forme, it is standby that symbol such as puts forth effort at the project rolling;
9) use press plate, alter the adhesive layer by the design lines number, check, oven dry rolling, viscosity mm≤3 are held in check;
10) product is cut through cutting machine, and test package dispatches from the factory.
The adhesive tape of making by such scheme, in the use, under normal circumstances, it has same function with general adhesive tape, relies on its non-setting adhesive effect of deadlocked with packed case or bag, is encapsulated in article in the case or in wrapping with the binding form.But if having person agaainst the law to adopt blowing hot wind in the logistics link or when changing the humidity mode and removing adhesive tape, easily separated layer is through easily separated layer of skewness of etch layer surface convex-concave, each point bonding force difference irregular come unstuck to peel off do not have viscosity, an involution again.And label layer destroyed have be bonded at being attached to tightly on the casing with non-drying glue layer of having on the film, anti-counterfeiting heat-sensitive printing ink changes color or separation.Make its opening person stay sharp trace.Next owner of logistics link can find tr easily and be unlocked, thereby, can in time find the problem source.
The present invention has solved existing adhesive tape effectively and has existed in the logistics progress in encapsulation casing or other wrapping body, being utilized blowing hot wind rising adhesive tape place's temperature or change adhesive tape all not to have vestige with the humidity of adhering to the place by illegal person seals off robber's thing, then again tr is bonded at the problem of not revealing mislead on the tr again with same adhesive tape.
