Processing method for packing tape

Abstract

The invention provides a processing method for a packing tape with better user experience. No right-angled corners are available at the upper and lower ends of a produced tape, so that a user is not cut, and meanwhile, the end face of a tape coil is not sticky, so that the tape is more convenient to take and use. The processing method comprises the following main steps: adding a tape raw material acrylic acid into an emulsification tank for emulsification; then putting the emulsified raw material into a reaction pot to be heated to prepare glue; then adding the glue into a coating machine; mounting a plastic thin film coil on the coating machine and smearing the glue to a plastic thin film through the coating machine to prepare a mother coil; pipe-cutting the mother coil through a pipe cutter; stripping the successfully pipe-cut tape through a stripping machine to obtain coils of tapes; polishing the upper and lower inner corners of a paper element of the stripped tape by using a polishing machine; polishing the right-angled corners with the inner corners to bevels or arc-shaped faces; and uniformly adhering paper element powder left when the right-angled corners are polished to the end face of the tape coil of the tape to prepare a finished product packing tape.

Description

technical field [0001] The invention relates to a processing method of an adhesive tape, in particular to a processing method of a case-sealing adhesive tape. Background technique [0002] Since Richard Drew invented scotch tape in St. Paul, Minnesota, USA in 1928. Tapes can be divided into high temperature tapes, double-sided tapes, insulating tapes, special tapes, pressure-sensitive tapes, die-cut tapes, and sealing tapes according to their functions. Different functions are suitable for different industry needs. A layer of adhesive is coated on the surface of the tape to make the tape stick to the object. The earliest adhesives came from animals and plants. In the 19th century, rubber was the main component of the adhesive; in modern times, various polymers are widely used. Take the sealing tape as an example, the sealing tape in the prior art is mainly a single-sided adhesive tape, and its structure is as attached figure 1 As shown in , it includes two parts: tape rol...

AI Technical Summary

Problems solved by technology

This kind of stickiness will cause the following inconveniences during the use of the sealing tape: 1. When the user takes a roll of tape from the stacked tapes, it is often caused by the mutual adhesion between the end faces of the tape rolls, resulting in It is very inconvenient to take out multiple rolls at a time

2. The end surface of the tape roll will stick to your hands, and it is easy to stick to things in contact with it when placed

[0016] To sum up, the sealing tape processed by the processing method of the sealing tape in the prior art has the following two disadvantages: 1. The upper and lower ends of the paper core 02 are right-angled corners, and when it touches the user's hand, When relatively rotating, it is easy to cut the user

2. When the user takes a roll of tape from the stacked tapes, it is inconvenient to use

3. The end surface 03 of the tape roll is easy to distribute. The glue is sticky and sticky during use. At the same time, it is easy to stick to the things in contact with it when it is placed.
