This article will delve into the BPA issue in thermal receipts, helping you understand its potential risks, and provide insights into BPA-related knowledge.
What is BPA?
BPA (Bisphenol A) is a chemical widely used in the production of plastics and resins. Since the 1960s, it has been utilized in a variety of consumer products, including food containers, beverage bottles, and can linings. In thermal paper, BPA is used as a color developer, enabling the paper to display text and images when exposed to heat.
What is Thermal Paper and Does it Contain BPA?
Thermal paper is a special type of paper coated with a heat-sensitive layer. When exposed to heat, the chemicals in the coating react to produce a color change, creating text or images. Traditionally, BPA is used in thermal paper as a color developer. However, with increasing awareness of BPA's potential health risks, many manufacturers are seeking alternatives. Common alternatives include BPS (Bisphenol S), which is structurally similar to BPA but considered to have less impact. Despite the ongoing debate about BPS's safety, some manufacturers have opted to completely remove bisphenol compounds, using non-phenol color developers or environmentally friendly alternatives such as VitexĀ®. These materials not only reduce health risks but also ensure the reliability and sustainability of thermal paper in commercial applications.
