Embodiment Construction

[0019] The present invention will be described in detail below with reference to the drawings and embodiments.

[0020] Please also refer to figure 1 and figure 2 , figure 1 is a structural schematic diagram of the web of the present invention, figure 2 yes figure 1 A cross-sectional view of a section of an embodiment of a web. The roll paper 10 of the present invention comprises a paper core tube 11 and a roll paper 13 wound outside the paper core tube 11, the paper core tube 11 comprises a surface layer 111 and an adhesive layer 115 arranged between the surface layer 111 and the roll paper 13 , the adhesive layer 115 is provided with a plurality of microcapsules filled with liquid.

[0021] When the web 10 is applied pressure to deform the paper core tube 11, the microcapsules are simultaneously squeezed to rupture, so that the liquid flows out from the microcapsules and penetrates into the adhesive layer 115, reducing the viscosity of the adhesive layer 115, thereby ...

Abstract

The invention provides a roll paper, which includes a paper core tube and a roll paper wound outside the paper core tube, the paper core tube includes a surface layer and an adhesive layer arranged between the surface layer and the roll paper, the adhesive layer There are a plurality of microcapsules filled with liquid; wherein, when the web is applied pressure to deform the paper core tube, the microcapsules are simultaneously squeezed to rupture, so that the liquid flows out of the microcapsules and penetrates into the adhesive layer, reducing The viscosity of the adhesive layer makes it convenient for the user to quickly pull out the paper core tube from the roll paper.

Description

technical field [0001] The invention relates to the technical field of household paper, in particular to a roll paper. Background technique [0002] The existing roll paper generally has a paper core tube, and there is friction between the paper core tube and the roll paper, or they are glued together. Currently, the cored roll paper sold on the market has a single purpose of the paper core tube, which only plays the role of supporting the roll paper layer. In the process of using the roll paper, many people will take out the core tube of the roll paper first, and take the paper from the inside to the outside for use. At present, this process is mostly done manually by the user. However, in the process of operation, the actual contact surface between the hand and the paper core tube is narrow, and it is difficult to exert force. It is difficult to extract the paper core tube quickly and conveniently, especially for some paper core tubes and roll papers that are very tightly...
