The invention has the advantages that:
the thermosensitive paper and the polyethylene layer are compounded without glue, so that the environment is protected and no pollution is caused; the release paper is not used, the square gram weight can be reduced, the cost is saved, and the product is light and thin.
The invention can be improved by the following scheme:
the silicone oil layer is UV solvent-free silicone or water-based silicone oil.
The polyethylene layer is composed of low-density polyethylene and high-density polyethylene.
The gluing layer is hot-melt pressure-sensitive adhesive or water-based pressure-sensitive adhesive.
The second purpose of the invention is to provide a preparation method of the backing-paper-free environment-friendly thermal label.
A preparation method of the backing-paper-free environment-friendly thermosensitive label comprises the following steps:
a. coating the silicon oil layer on the heat-sensitive surface of the heat-sensitive paper through a coating machine, and then curing through an oven;
b. uniformly mixing low-density polyethylene and high-density polyethylene together through a stirrer, melting the mixed polyethylene layer through a laminating machine, and uniformly coating the polyethylene layer on the non-heat-sensitive surface of the heat-sensitive paper through a die head;
c. and c, obtaining the thermosensitive composite layer after the step a and the step b are finished, coating a glue coating layer on the thermosensitive composite layer to form the backing-paper-free environment-friendly thermosensitive label, and rolling the backing-paper-free environment-friendly thermosensitive label to form a product.
The invention has the advantages of convenient and simple processing, energy saving and environmental protection.
The invention can be improved by the following scheme:
after the coating layer is coated with the water-based pressure-sensitive adhesive on the heat-sensitive composite layer, an oven is needed to be used for drying after the coating. The coating weight of the polyethylene layer is 10-40 g/the coating weight of the silicon oil layer is 0.5-3 g/m2。
