Abstract

The invention provides a preparation method for a paper tablecloth, and the paper tablecloth, belonging to the technical field of paper tablecloths. The preparation method for the paper tablecloth provided by the invention comprises the following steps: successively stacking a first paper layer, a second paper layer and a polyethylene film layer, and carrying out rolling at a temperature of 25 to 60 DEG C. The preparation method for the paper tablecloth provided by the invention adopts two paper layers and the polyethylene film layer to laminate through a manner of rolling, and by relying on the adhesion force between the paper layers or the paper layers with polyethylene at a certain temperature, bonding firmness among all layers is guaranteed, so the application requirements of the paper tablecloth is met. The method provided by the invention also avoids the disadvantages of complicated processing process and high production cost due to the use of a binder during lamination of the paper layers and the polyethylene film layer in the prior art, and is applicable to large-scale popularization and application.

Description

technical field [0001] The invention relates to a method for preparing a paper tablecloth and the paper tablecloth, belonging to the technical field of paper tablecloths. Background technique [0002] Tablecloths can be covered on tables and tabletops to prevent dirt or increase the appearance, and also become tablecloths or tablecloths. Traditional tablecloths are generally cloth materials that can be used multiple times or plastic materials that can be used once. Cloth tablecloth can be replaced and cleaned, which is convenient to save cost, but its oil resistance is poor, and it is difficult to clean after sticking oil. If it is damaged, the cost will be relatively high, and the surface of cloth material is not conducive to beautiful printing design. Disposable plastic tablecloths are easy to use and do not need to be cleaned, but their water and oil absorption properties are poor, and they cannot be degraded, which is not conducive to environmental protection. [0003]...
