A patent application (Publication Number: US20240034046A1) describes a method for producing a linerless non-top coated thermal printable material. The method involves preparing a thermal printable material by applying a heat-resistant material and a heat-sensitive material on a base printable material. The thermal printable material is then subjected to a supercalendering operation to achieve a smooth surface finish. The supercalendering operation includes passing the material through at least two calender rolls at specific temperature, speed, and pressure ranges. Additional features include applying a barrier layer, adhesive layer, and release layer to enhance the properties of the linerless non-top coated thermal printable material.

The patent application further details the composition and characteristics of the linerless non-top coated thermal printable material, including basis weight, thickness, smoothness, porosity, surface roughness, water absorbability, oil absorbability, and brightness. The material is designed to have specific properties within defined ranges to ensure optimal performance. The presence of an adhesive layer with pressure-sensitive adhesive and a release layer adds functionality to the material. Additionally, a barrier layer can be applied under the material for further protection and enhancement. Overall, the method and resulting product aim to provide a high-quality linerless non-top coated thermal printable material suitable for various applications.
