PET material film substrate label

The film substrate label of PET material, full name Polyethylene Terephthalate film label, is a polymer material label with excellent physical and chemical properties. The following is a detailed introduction to the PET material film substrate label:

First, material characteristics

Hard brittleness: PET labels have good hard brittleness, so that the label can maintain good shape stability in the application.

High temperature resistance: PET labels can withstand certain high temperatures (usually below 200 degrees), and can withstand higher temperatures in short-term use, which makes it suitable for label applications that need to be used in high temperature environments.

Chemical resistance: PET labels can resist the corrosion of chemicals such as acid and alkali, and are suitable for harsh environments or occasions where chemical substances need to be resisted.

Mechanical strength: Although the PET material is thin but high strength, the impact strength is 3 to 5 times that of other films, and has good folding resistance, making the label not easy to damage during use.

Waterproof and oil resistant: PET labels have excellent water and oil resistant properties, suitable for use in wet or oily environments.

Gas barrier: The gas and water vapor permeability of PET film is low, with excellent gas resistance, suitable for applications that need to block gas or water vapor.

2. Appearance and type

Color: PET label color variety is rich, common dumb silver, dumb white, bright silver, bright white and transparent several.

Thickness: According to thickness, PET labels have 25 times (1 time =1um), 50 times, 75 times and other specifications, and the specific thickness is determined according to the actual requirements of the manufacturer.

3. Application fields

Given the many excellent properties of PET labels, it is widely used in various industries, including but not limited to:

Electronics: Used for identification of electronic products such as mobile phone batteries and computer monitors.

Household appliances: Labels for household appliances such as air conditioning compressors and refrigerators.

Automotive: Used for identification of automotive parts, interiors, etc.

Chemical: Used for chemical packaging, storage container label.

Others: It is also suitable for bathroom supplies, cosmetics, jewelry, all kinds of electrical appliances, mechanical products and other applications that require high-quality labels.

4. Printing and processing

Printing process: The printing process of PET film is diverse, including flexographic printing, offset printing and digital printing. During the printing process, PET films require appropriate pre-press treatment to improve surface energy or wetting capacity and ensure the firmness of the ink.

Drying and curing: The PET film after printing requires proper drying and curing treatment to ensure printing quality. This can be achieved by means of gas drying, hot air curing or UV curing.

Post-treatment: According to needs, you can also carry out post-treatment steps such as coating film, hot stamping, polishing, etc., to enhance the texture and durability of the print.

5. Environmental Protection and Sustainability

With the increasing attention to environmental issues, the film substrate label of PET material also meets the environmental requirements. PET materials can be recycled and non-toxic, tasteless, hygienic and safe can be directly used in food packaging to further reflect its environmental protection and sustainability.

In summary, the film substrate label of PET material occupies an important position in the label market because of its excellent physical and chemical properties and a wide range of application fields. With the continuous progress of technology and the improvement of environmental protection requirements, the performance and application range of PET labels will continue to expand and improve.
