Method for producing low-noise biaxially-oriented polypropylene (BOPP) pressure sensitive adhesive tape with paper core with inner diameter of 25.4mm

Abstract

The invention provides a method for producing a low-noise biaxially-oriented polypropylene (BOPP) pressure sensitive adhesive tape with a paper core with the inner diameter of 25.4mm. A slitting technology for an adhesive tape with the paper core with the inner diameter of 25.4mm is realized; low-noise effect treatment is realized on the basis of slitting of the adhesive tape with the paper core with the inner diameter of 25.4mm; and problems that the inner diameter of a paper core of a low-noise BOPP pressure sensitive adhesive tape cannot be 25.4mm, and the noise of an adhesive tape with a paper core with the inner diameter of 25.4mm cannot be low are solved. By the produced low-noise BOPP pressure sensitive adhesive tape with the paper core with the inner diameter of 25.4mm, conveying space can be effectively saved, and the conveying efficiency is improved; and moreover, the low-noise BOPP pressure sensitive adhesive tape is different from a common-noise adhesive tape with a paper core with the inner diameter of 25.4mm, and has a low-noise effect, the noise of the low-noise BOPP pressure sensitive adhesive tape can be below 30 decibels, and the BOPP pressure sensitive adhesive tape is an environment-friendly BOPP adhesive tape.

Description

technical field [0001] The invention relates to the technical field of adhesive tape production methods, in particular to a production method of a low-noise BOPP pressure-sensitive adhesive tape with a paper core inner diameter of 25.4mm. Background technique [0002] At present, the inner diameter of the paper core used in the low-noise adhesive tape produced in the same industry is 76.2mm. The production technology process is: cut the produced semi-finished products into tapes of different lengths through a slitting machine, and the length of the finished adhesive tape is automatically controlled by the slitting machine according to the setting, and the length can be set arbitrarily, such as 50m, 66m etc. Corona treatment is performed on the non-adhesive surface of the adhesive tape during the slitting process to change the surface tension of the BOPP film, reduce the noise generated when the adhesive tape is unwound, and achieve a low-noise effect. However, the inner di...

Problems solved by technology

[0004] The technical problem to be solved in the present invention is to provide a production method for low-noise BOPP pressure-sensitive adhesive tapes with a paper core inner diameter of 25.4mm, to realize the slitting technology for adhesive tapes with a paper core inner diameter of 25.4mm. The low-noise effect treatment is carried out on the basis of slitting the adhesive tape of mm, which solves the problem that the low-noise BOPP pressure-sensitive adhesive tape cannot be produced with a paper core with an inner diameter of 25.4mm, and at the same time solves the problem of gluing the paper core with an inner diameter of 25.4mm.
