Two-faced adhesive tape and production method thereof

Abstract

The invention discloses a double sticky tape and a production method thereof. The tape comprises a release paper layer consisting of a tape matrix layer, as well as an upper and a lower anti-adhesion layer which are coated and connected on the upper and lower surfaces of the tape matrix layer. A viscose layer is coated and connected on the upper surface of the release paper layer and consists of independent voltage-sensitive glue film units that have the same thickness and are continuously and uniformly arranged. The production method comprises the steps of: coating an organic silicon anti-adhesion layer on the upper and the lower surfaces of a plastic film or a fiber paper tape taken as the tape matrix layers so as to be used as the release paper; then coating the independent voltage-sensitive glue film units that have the same thickness and are continuously and uniformly arranged on the surface of the anti-adhesion layer on the release paper so as to be used as the viscose layer, and after being made by the furling of a material receiving roller of a coating machine, a double sticky tape wound roll is put on a slitting machine so as to be separately slit into a tape with required width, and is then wound into a wound roll type tape core finished product with required specification size. The invention has the beneficial effects that with the tape core assembled on an applicator box, the phenomenon of tape dragging and wire drawing does not happen in the use process, thus ensuring neat and clean coating of the viscose film.

Description

technical field [0001] The invention relates to a double-sided adhesive tape in stationery, in particular to a double-sided adhesive tape made into a reel-shaped tape core and installed in an applicator box and a production method thereof. Background technique [0002] At present, a kind of double-sided adhesive tape comprising a release paper, coated with an adhesive layer on one side of the release paper layer, then wound into a reel-shaped tape core and installed in the applicator box, Because of its convenience, it is widely used in the bonding of paper or objects. But, the adhesive layer of its adhesive tape of existing product is to be coated on the release paper layer continuously and evenly when producing, and in actual use, see Figure 4 ~ Figure 5 As shown, the film of the adhesive layer of the adhesive tape moves back with the pressure of the head of the tape box on the surface of the paper or object, and is separated from the connection with the release paper lay...

AI Technical Summary

Problems solved by technology

The double-sided adhesive tape of this patented technology also has the product that is wound into certain width, the reel-shaped belt core of size and is installed in the applicator box body at present and sells on the market, but the product of this patented technology is the same as the one mentioned above. Compared with the double-sided adhesive tape of the above-mentioned technology, its adhesive layer is made up of a film layer (commercially available as paper) and two colloidal layers. Its disadvantages are: the structure is relatively complicated, which leads to complicated production process, which consumes a lot of man-hours, energy and materials, resulting in high production costs, and the thickness of the tape is thicker due to the number of layers of tape. The length of the tape that can be loaded is much smaller than the aforementioned double-sided tape, which also increases the cost of product packaging
