Abstract

The invention discloses a waterborne PP straight surface sticker and a manufacturing process thereof. The waterborne PP straight surface sticker is composed of a base material, a coating, glue, a bottom layer and a release paper, wherein the coating is uniformly applied onto the lower surface of the base material, one surface of the bottom layer is adhered to one surface of the coating, the othersurface of the bottom layer is coated with the glue to form a glue layer, and the release paper is adhered to the glue layer. By improving the formula and the manufacturing method of the straight surface sticker, the properties of the straight surface sticker can be improved, the manufactured straight surface sticker can be structurally compact among layers and less prone to loosening and deformation during application, meanwhile, the glue layer is high in viscosity and less prone to falling off during application, so that the waterborne PP straight surface sticker has a broad market space.

Description

technical field [0001] The invention relates to the technical field of direct-face stickers, in particular to a water-based PP direct-face sticker and a manufacturing process thereof. Background technique [0002] The decorative sticker is composed of a bottom release paper layer and a functional paper layer pasted on it. It is characterized in that the functional paper layer is composed of white PVC and black PVC thermally compounded. holes to form a grid. The small hole is a circular hole, and of course other shapes can also be used. The decorative sticker adopting the above structure has relatively low cost and can be seen through on one side. [0003] Due to the loose structure between layers, existing direct-face stickers are easily deformed during use, thereby affecting the use effect of direct-face stickers and further affecting the economic benefits of direct-face sticker manufacturers. Contents of the invention [0004] The object of the present invention is to...
