There are a wide variety of goods on the market now, and the packaging is also different. However, the competitiveness of packaging has also begun to strengthen year by year, becoming one of the means to attract customers. Among them, flexible packaging occupies a huge market in the packaging industry, and has become the mainstream because of its diverse forms of expression and rich color functions. So, what kinds of soft packaging materials are there? Let's take a look with Bian Xiao.

What kinds of flexible packaging materials are there?

1, thermal paper

Thermal paper is a kind of paper with high thermal sensitivity and thermal coating. High-sensitivity surface materials can be used for low-pressure print heads, so the wear of the print heads is very small. Thermal paper is a kind of thermal paper specially used for electronic scales and cash registers. The easiest way to test thermal paper is to scrape it with your nails, which will leave black scratches. Thermal paper is suitable for shelf labels such as cold storage and freezer, and its size is mostly fixed at 40mmX60mm standard.

2.PVC advanced label paper

PVC is the abbreviation of vinyl, and it is also a polymer material. Common colors are sub-white and pearl white. The performance of PVC is close to that of PET. Compared with PET, it has better flexibility and softer feel, and is often used in some high-end occasions such as jewelry, watches, electronics and metal industries. However, PVC has poor biodegradability, which has a negative impact on environmental protection. Some developed countries abroad have begun to develop alternative products in this field.

3.PET advanced label paper

PET is the abbreviation of polyester film. It's actually a polymer material. PET is hard and brittle, and the common colors are silver, white and bright white. According to the thickness, there are 25 times (1 times = 1um), 50 times, 75 times and other specifications, which are related to the actual requirements of manufacturers. Because of its excellent dielectric properties, PET is widely used in many special occasions, such as mobile phone batteries, computer monitors, air-conditioning compressors and so on. In addition, PET paper has good natural biodegradability, which is paid more and more attention by manufacturers.

4, coated paper label

It is a common material for bar code printers, and its thickness is generally around 80g. Widely used in supermarkets, inventory management, clothing tags, industrial production lines and other places where the amount of coated paper labels is more. According to the sales of Sky barcode labels for many years, the users of American Avery paper and Japanese Prince paper have the best response among domestic and foreign brands, especially American Avery copper plate label paper, whose white super-smooth uncoated paper is an excellent basic material for thermal transfer printing.

Application of soft packaging materials

Nowadays, soft packaging products can be seen everywhere, and soft packaging materials are mainly used for hard box packaging, because it is a material that can be closely attached to goods without affecting the printing effect, and has high identifiability. In the era when the product is difficult to distinguish between true and false, its anti-counterfeiting logo is clearly visible and firm. In addition, it has good heat resistance and smoothness, and can be used not only by packaging machine but also by hand. Soft packaging materials are used for hard box packaging, such as food, medicine or cigarettes. It can be seen that although flexible packaging is competitive in the market, it also has enough room for development. I hope that the continuous progress of packaging technology can bring more convenience to everyone's life!
