Is BOPP color thermal synthetic paper safe and non-toxic?

The safety of BOPP color thermosensitive synthetic paper is a complex issue, which needs to be analyzed from many angles.

First of all, BOPP (biaxially stretched polypropylene) synthetic paper, as a packaging material, has a wide range of applications in food, cosmetics, medicine and other fields. It has excellent moisture-proof, mildew-proof and bacteria-proof properties, which can effectively protect products from the external environment. In addition, BOPP synthetic paper also has excellent printing performance, which can print exquisite patterns and text, making the product more attractive. These advantages make BOPP color thermal synthetic paper popular in the market.

However, the question of whether BOPP color thermal synthetic paper is safe and non-toxic mainly concerns the chemicals in its thermal coating. The production principle of thermal paper is to coat a layer of "thermal paint" on the ordinary paper base to form a thermal discoloration layer, when the thermal paper encounters a hot print head, the film melts, and the colorless dye printed at the print head reacts chemically with the color development agent, from colorless to black or other colors. In this process, the chemicals in the heat-sensitive coating may have a certain impact on human health.

In particular, it is important to note that one of the commonly used color developing agents in thermal paper is bisphenol A (BPA). Although BPA is A low-toxic chemical and relatively stable at room temperature, it may cause damage to the human body if heated or exposed for a long time, such as increasing the risk of cancer and causing endocrine disorders in those exposed. Therefore, for sensitive groups such as infants and pregnant women, special attention should be paid to controlling the amount and time of contact with thermal paper to avoid possible physical damage.

However, it should be pointed out that there are many manufacturers of thermal paper on the market at present, and their formulations and specifications are different, and the dosage of bisphenol A is also different. Some high-end thermal paper products may have adopted BPA-free formulations, thus greatly reducing the potential harm to the human body.

In summary, the safety of BOPP color thermal synthetic paper depends on the composition and content of the chemical substances in its thermal coating. Under normal circumstances, BOPP color thermal synthetic paper produced by regular manufacturers and in line with relevant standards should be relatively safe. However, in order to protect their own health, it is recommended to pay attention to the following points when using:

1.Try to avoid long-term contact with thermal paper, especially after heating thermal paper.

2.After touching the thermal paper, wash your hands in time to avoid bringing harmful substances into the mouth.

3.For sensitive groups such as infants and pregnant women, special attention should be paid to controlling the amount and time of exposure to thermal paper.

In addition, if possible, it is recommended to choose high-end thermal paper products that do not contain harmful chemicals such as bisphenol A.
