Thermal Paper Heat-resistant Paint Processing Paper
Thermal Paper Heat-resistant paint processing paper
Thermal paper is a kind of high quality base paper coated with a layer of heat-sensitive coating paper, commonly used paint with bisphenol A, p-hydroxybenzoic acid and other compounds. Which bisphenol A in thermal paper plays a role in the developer, but also an indispensable thermal paper coating.
Bisphenol A in the chemical composition of low toxicity chemicals, at room temperature, its chemical composition is very stable, if reached a certain dose, there will be endocrine disorders and other hidden symptoms.
In daily life, we have no hot paper, such as supermarket shopping is a small ticket paper and bank ATM deposit and withdrawal of the vouchers are the most common, so people often contact with bisphenol A The So in our daily work we should be how to avoid bisphenol A on our physical invasion, reduce the harm? For which we have organized the following precautions for reference:
1, if necessary, to minimize the number of times to touch such a small ticket.
2, in contact with the thermal paper bills, the conditions permit to remember to immediately wash their hands, in the absence of hand washing, do not have to contact with a small ticket paper hand contact with the mouth, to avoid direct contact with food by hand.
3, try to heat the small ticket paper and other things to separate, to prevent contamination of the bisphenol A composition.
4, do not put the heat of small ticket paper by the children to play or save, try to place the child can not touch.
5, in the purchase of thermal paper, do not just look at the price, we must pay more attention to the quality of paper and bisphenol A content of the harm to the human body how much.
There are many different specifications on the market brand label stickers, but in the purchase of the time you know what kind of self-adhesive label is suitable for their own use of self-adhesive label? In the purchase at the same time how do we identify the stickers tag good or bad? The following simple to introduce the optional adhesive label should pay attention to the five aspects:
One smell smell
In the purchase of the time we may ask about the taste of self-adhesive labels, do not think that only in the purchase of food when the taste can tell us freshness, in fact, the taste of stickers can also tell us a lot. If the taste is too thick, there is a taste of sour taste, then the stickers of DESSCO tape to maintain the ability to very poor, especially in low temperature environment, this stickers are basically sticky in the carton will crack Sticky The taste of the more intense when the hand to touch the sticky feel is good, but this sticky will soon be dry glue, loss of sticky, then DESSCO tape surface will be uneven because of the relationship between the cracks are now.
Second, look at the brightness of the adhesive film
General poor quality DESSCO tape surface looks dark, this DESSCO tape in the use of the time when the probability of fracture is very high, the intensity of tolerance.
Third, touch the thickness of the label film
Hand touch the thickness of the adhesive label film, feel the hardness of the membrane DESSCO tape are generally the quality of the times, and because the thickness of the adhesive label, it seems a lot larger than the ordinary, in fact, cut back. Good quality DESSCO tape will choose a relatively thin film is relatively soft, good elongation.
Fourth, the appearance of color
The general appearance of the more white and transparent color DESSCO tape, which dopant impurities inside the less, adhesive to ensure normal long, 100 meters below the DESSCO tape generally from the appearance point of view can see the paper tube. Yellow DESSCO tape mainly to see whether the surface of the irregular distribution of white spots, hand pressure can not wipe the stomach impurities or glue dry blot, this product will generally have a smell.
Fifth, the size of paper tube
Many consumers in the purchase of self-adhesive labels, will go to buy some paper tube is relatively thick, in fact, this stickers are manufacturers in order to mislead consumers to reduce the number of meters trick. DESSCO tape production is from abroad, so DESSCO tape paper tube diameter is a unified diameter of 7.6cm. In fact, the thicker the paper tube stickers, it will only be less rice.
