Self-adhesive label paper is a composite material with paper, film or special material as the fabric, adhesive on the back, and silicon-coated protective paper as the background. Because of its advantages of no need to apply glue, no paste, no need to dip in water, no pollution, and save labeling time, it is widely used in various industries. At present, the most commonly used ones on the market are thermal paper labels and coated paper labels. But what is the difference between thermal paper labels and coated paper labels?

What is a thermal paper label?

Thermal paper is specially used on electronic scales and a kind of thermal printing paper in cash registers. The easiest way to test thermal paper: use your nails to scratch the paper hard, and a black scratch will be left. Thermal paper is suitable for shelf labels in cold storage and refrigerators, and its size is mostly fixed at the standard of 40mmX60mm.

Thermal paper is specially used for printing on thermal printers and thermal fax machines. Its quality directly affects the printing quality and storage time, and even affects the service life of printers and fax machines. The material characteristics of thermal label paper are not waterproof, not oil-proof, and can be torn.

What is a coated paper label?

Coated paper is a commonly used material for barcode printers, and its thickness is generally around 80g. Widely used in supermarkets, inventory management, clothing tags, industrial production lines and other places where coated paper labels are used more. Ordinary coated paper semi-glossy white coated paper, the basic weight is 80 grams per square meter, the thickness of the surface substrate is 72 fan, and the overall thickness of the label is 147 fans. The operating temperature range is -50 degrees +90 degrees, and the lowest labeling temperature is +7 degrees.

At present, copper plate label paper is widely used in supermarkets, inventory management, clothing tags, and industrial production lines, and is suitable for promotion and semi-high-gloss color printing in industry. Typical applications such as cosmetic labels, pharmaceutical labels and food industry labels. Can be applied to the flat and simple curved surfaces of most substrates, including cardboard and plastic film.

the difference between the thermal paper label and coated paper label?

1. The storage time of coated paper labels is longer than that of thermal paper labels

Generally, the storage time of coated paper labels is about 2 years, but due to the nature of thermal paper labels, the storage time of thermal paper labels is only about half a year. It is stored for about one year, so when buying labels, you need to decide according to the storage time of the products you posted. For example, the product you posted is the outer packaging of bread, and the storage time is only two or three days. At this time, you can use it Labels made of heat-sensitive paper, but if the product you are pasting is an outer box and requires a storage time of more than one year, then you need to choose a coated paper label, such as electronic products exported to foreign countries.

2. Coated paper labels are less affected by temperature, but thermal paper labels are greatly affected by temperature

Generally, when the temperature of the thermal paper label is higher than 30 degrees, the handwriting printed on the label is easy to disappear. What is the reason? The main reason is that when the temperature is too high, a chemical reaction occurs on the surface of the thermal paper label, causing the handwriting to disappear. . Because the surface of the thermal paper label contains a chemical layer, but the coated paper does not, the coated paper is less affected by the temperature. Generally, if the label attached to the surface of the product is greatly affected by temperature, it is generally recommended to choose coated paper.

3. The most obvious difference is that the coated paper label needs to be printed with a carbon ribbon, while the thermal paper label does not need a carbon ribbon to print. There is a certain difference in cost, and it may cost another sum to use a copper plate label The funds are on the purchase of carbon ribbons, and thermal paper is not used. It can be directly installed in a barcode printer for printing, provided that the barcode printer supports thermal printing.
