Description

Technical Field

[0001] The present invention relates to the technical field of correction tapes, and in particular to a low-cost, more environmentally friendly, higher-capacity linerless correction tape original film and a production process thereof. Background Art

[0002] Correction tape is an office supply used to correct errors in paper documents. It is very simple to use. Just cover the wrong words with the correction tape to achieve the correction effect. Correction tape is very easy to use and will not damage the original paper. Therefore, it is widely used in offices, schools and other places.

[0003] like Figure 1 As shown, the production process of conventional correction tape 200 involves first mixing the conventional raw material 300 for conventional correction tape 200. The white conventional raw material 300 is then coated onto release paper A. After initial drying in a dryer 30, a conventional film body B is formed. A conventional glue layer C is then applied to the surface of the conventional film body B using a gluing machine 40. After a secondary drying in the dryer 30, the conventional correction tape 200 is produced. Finally, a rewinder 50 winds the conventional correction tape 200 into a roll. Although not shown in the figure, the wound conventional correction tape 200 can be further divided into smaller rolls and stored in correction tape cases.

[0004] The problem with the above-mentioned traditional correction tape 200 is that it requires release paper A, which increases the overall cost, has limited capacity, increases waste, affects the environment, and is not conducive to environmental protection. The production process is not simplified enough, and there is room for optimization of the overall cost.

[0005] In view of this, how to provide a linerless correction tape original film that can solve the above problems has become the subject to be improved by the present invention. Summary of the Invention

[0010] More specifically, after the winding step, there is also a sub-packaging step, wherein the sub-packaging step is to pack the wound-up linerless correction tape original film into small rolls, and then install the packed small rolls in corresponding correction tape shells.

[0011] More specifically, the membrane body at least contains titanium dioxide, synthetic resin, dispersant, film-forming aid, linear polyethylene resin, toughening agent and anti-sticking agent; the glue layer at least contains glue.

[0012] More specifically, in the two technical means, the titanium dioxide is titanium dioxide; the synthetic resin is an organic polymer; the dispersant is a surfactant; the film-forming aid is a coalescing aid; the linear polyethylene resin is high-density polyethylene (HDPE); the toughening agent is a high molecular polymer; the anti-sticking agent is a 1605SBR anti-sticking agent (Suylym 1605SBR) manufactured by DuPont of the United States; and the glue is acrylate.

[0013] More specifically, in the two technical means, the content of the titanium dioxide is 75wt%; the content of the synthetic resin is 5wt%; the content of the dispersant is 3wt%; the content of the film-forming aid is 2wt%; the content of the linear polyethylene resin is 5wt%; the content of the toughening agent is 2wt%; the content of the anti-sticking agent is 3wt%; and the content of the glue is 5wt%.
