How to use PET release film to improve the product quality of pressure-sensitive labels and tapes?
Publish Time: 2025-06-17
In the modern packaging and labeling industry, pet solvent-free release film is widely used as a key material in the production of pressure-sensitive labels, tapes and various adhesive products. This film not only provides excellent physical properties, but also has environmental characteristics, making it the preferred backing material for many manufacturers.
Pet solvent-free release film is known for its excellent transparency, strength and chemical resistance. It is often used in applications that require high transparency and good mechanical properties, such as electronic device screen protectors, food packaging labels, and labels for pharmaceutical products. It is particularly worth mentioning that PET release film manufactured using solvent-free production processes not only meets high performance requirements, but also meets increasingly stringent environmental standards.
Solvent-free process is a green manufacturing technology developed in recent years. Its main advantage is that it reduces the emission of volatile organic compounds (VOCs) and reduces the risk of environmental pollution. The organic solvents used in the production process of traditional solvent-based release films are not only harmful to the environment, but also pose safety risks. In contrast, solvent-free release films avoid these problems by using hot melt or UV curing technology to form the release layer. This not only helps companies reduce waste gas treatment costs, but also enhances their social responsibility image.
When pet solvent-free release film is used as a backing material, its surface is coated with a special release agent, which allows the film to be easily peeled off from the adhesive layer without leaving any residue. This feature is essential to ensure that labels and tapes maintain good adhesion before use. At the same time, due to the high tensile strength and dimensional stability of the PET substrate, it can maintain its original shape and function even in high temperature or high humidity environments, which is very critical to ensure product quality.
In addition, pet solvent-free release film can also be customized according to specific needs, including adjusting thickness, transparency, and surface treatment methods. For example, in some high-end electronic products, ultra-thin and anti-static PET release film may be used to prevent static electricity accumulation from damaging sensitive components; while in the field of food packaging, more attention may be paid to the safety and barrier properties of the material to extend the shelf life and keep the food fresh.
With the continuous changes in market demand and technological progress, the application scope of PET release film is also expanding. In addition to the traditional label and tape industry, it is also used in solar panels, automotive interiors, medical equipment and other fields. Especially in the new energy industry, PET release film has become one of the ideal choices for photovoltaic module encapsulation due to its excellent electrical insulation and weather resistance.
With its excellent physical properties, environmental protection characteristics and wide applicability, pet solvent-free release film has become an indispensable part of modern industry. Manufacturers pursuing efficient production and enterprises concerned with environmental protection and social responsibility can benefit from this innovative material. In the future, with the development of new material science and changes in market demand, PET release film is expected to continue to evolve and provide better solutions for more fields.
