POS Billing Roll - 70 GSM

POS Billing Roll - 70 GSM is a type of paper roll specifically designed for point-of-sale (POS) billing and receipt printing. The "70 GSM" refers to the weight of the paper, which stands for grams per square meter. The content and composition of a specific POS Billing Roll - 70 GSM can vary, but I can provide a general overview of its typical components.

POS Billing Rolls are commonly made from thermal paper, which is coated with a heat-sensitive layer for printing purposes. The primary components of thermal paper used in POS Billing Rolls include:

1. Base Paper: The base paper is the foundation of the roll and provides structural support. It is typically made from high-quality wood pulp or other fibers, ensuring strength and durability for printing.

2. Thermal Coating: The thermal coating is a crucial component that enables the printing process. It consists of a mixture of colorless dyes, developers (such as bisphenol A or bisphenol S), binders, and other additives. When heat is applied to the thermal coating, it undergoes a chemical reaction, resulting in the generation of visible text, graphics, or images.

The exact formulation and content of the thermal coating can vary depending on the manufacturer and specific product line. Manufacturers may use different combinations of dyes, developers, and additives to achieve desired print quality, durability, and resistance to fading or smudging.
