The difference between glassine backing paper and white heavy backing paper in thermal paper
Thermal paper is also known as thermal fax paper, thermal recording paper, thermal copy paper. As a kind of processed paper, thermal paper is manufactured by coating a layer of "thermal paint" (thermal discoloration layer) on high-quality base paper. The back is coated with adhesive, and the backing paper is attached, which is called a thermal paper self-adhesive label.
The release paper is commonly known as "backing paper". The backing paper has an insulating effect on the adhesive, so it is used as the attachment of the facial paper to ensure that the facial paper can be easily peeled off from the backing paper. Commonly used are glassine paper (glassine) or white thick bottom, kraft paper, polyester (PET), polyethylene (PE) and so on.
Let's take you to understand the difference between glassine backing paper and white thick backing paper in thermal paper:
Glassine bottom paper, referred to as grid bottom, is divided into white grid, blue grid, and yellow grid. The three are different colors. Thermal paper usually uses white and blue grids. The backing paper is specially designed for high-speed web printing die-cutting and automatic labeling, with excellent die-cutting performance, good thickness and light transmittance.
White heavy base paper with excellent flatness, suitable for sheet-fed applications, and good strength for die-cutting on flat or round press equipment.
In general, each has its own advantages and characteristics. How to choose the right backing paper, you can choose according to your labeling method, that is, you need to roll or cut.
