Abstract
The invention provides a heat-sensitive paper suitable for a backing-paper-free label and a manufacturing method thereof. According to the heat-sensitive paper suitable for the backing-paper-free label, a surface material layer, a first isolation layer, a thermo-sensitive color developing layer, a second isolation layer, a silicone oil layer, a bottom adhesive layer and a stripping layer are arranged in a stacked mode from top to bottom; the first isolation layer and the second isolation layer respectively have water permeation resistance and grease resistance, the water resistance and the grease resistance of the heat-sensitive paper can be improved, the surface material layer is made of a raw paper material, so that the surface material layer can be conveniently marked in an ink form, and the bottom adhesive layer is covered with the heat-sensitive paper through the stripping layer, so that the stripping layer is uncovered when the heat-sensitive paper is used, and the adhesion stability of the heat-sensitive paper is improved. Therefore, the heat-sensitive paper applicable to the backing-paper-free label has the characteristics of small thickness, low manufacturing cost, high waterproof and grease-proof properties and good adhesiveness.
Description
technical field [0001] The invention relates to the technical field of heat-sensitive paper, in particular to heat-sensitive paper suitable for bottomless paper labels and a manufacturing method thereof. Background technique [0002] Thermal paper, also known as thermal recording paper or thermal copy paper, is essentially a processed paper, which is made by coating a layer of thermal color-developing paint on the base paper and then under the action of thermal printing to make the thermal paper The heat-sensitive color-developing paint undergoes a color reaction to form corresponding characters or patterns. Existing thermal papers can be divided into thermal papers with backing paper and thermal papers without bottoming paper. The thermal papers with backing paper usually consist of multiple paper layers stacked on each other, which have larger thickness and more complicated The production process is not conducive to reducing the production cost of thermal paper and realiz...
