preparation example Construction

[0035] The preparation method of the release agent in the present invention is: according to the proportioning ratio of the components in the formula, sequentially add organosilicon polymer, solvent, crosslinking agent, other additives and crosslinking catalyst into the stainless steel reaction vessel, then stirrer at 200R / Stirring speed at 21-25°C for 20 minutes.

[0036] The front and back surfaces of BOPP film are coated with LOGO release agent and light peeling force release agent respectively. The adhesion strength between light peeling force release agent and BOPP film is relatively low, and there is a silent effect when the tape is pulled from the roll. No noise will be produced. The bonding strength of LOGO release agent and BOPP film is lower than that of LOGO release agent and adhesive. After the tape is peeled off, dry glue with LOGO will be left on the sealed item.

[0037] Step 4: The BOPP film after the release agent treatment is coated with water-based acrylic ...

specific Embodiment

[0038] 1) The BOPP film is conveyed to the corona machine by the guide roller. Under the conditions of power of 20KW, temperature of 40°C and tension of 15-25kgf, corona treatment is performed on the front and back surfaces of the BOPP film, cooled by the cooling roller, and then The winding tension is 10-19kgf, and the guide roller is winding at a speed of 70m / min; the thickness of the BOPP film selected is 28-50μm.

[0039]2) The corona-treated BOPP film is printed ink on the front surface of the BOPP film through a printing roller with a printing tension of 15 to 25 kgf, and is dried in an oven at a temperature of 100° C. The roll tension is 10~19kgf, and the speed is 70m / min. The guide roller is wound.

[0040] 3) The BOPP film after ink printing is coated with a light release force release agent on the reverse surface of the BOPP film through an anilox roller with a coating tension of 20-25kgf, and then passed through the LOGO mark printing roller on the front surface of ...

Abstract

The invention discloses a making method for an anti-fake soundless adhesive tape. Specifically, the technological steps include: 1. conducting corona treatment on the front surface and back surface of a BOPP film by a corona machine; 2. printing ink on the front surface of the corona treated BOPP film by a printing roller with printing tension of 15-25kgf; 3. coating the back surface of the ink printed BOPP film with a light release force release agent through an anilox roller with coating tension of 20-25kgf, then coating the ink layer on the BOPP film front surface with a LOGO release agent through a LOGO sign printing roller; and 4. coating the LOGO release agent layer on the front surface of the release agent treated BOPP film with a water-based acrylic glue through a gumming roller with coating tension of 20-30kgf, and adjusting the gumming thickness to 20 micrometers by a winding bar under the assistance of a press roller.

Description

technical field [0001] The invention relates to a production process of an adhesive tape, in particular to a production process of an anti-counterfeit silent adhesive tape for packaging. Background technique [0002] With the development of high technology and the improvement of consumers' requirements for packaging safety, anti-counterfeiting tapes, anti-counterfeiting films and anti-counterfeiting papers with anti-counterfeiting functions can be applied to important document bags, courier bags, court evidence bags, etc. according to product characteristics. Or it is used for the sealing of controlled drugs, cartons, etc. For the anti-counterfeiting adhesive tape, a coating layer with anti-counterfeiting marks is coated on the back of the base material of the adhesive tape, and an adhesive is coated on the coating layer to complete, so that the adhesive tape is sealed on the article. [0003] However, the existing anti-counterfeiting adhesive tape can be opened and reused ...
