Why Choose Polyester Film?

Polyester (PET) film is a kind of plastic film with complete performance and a wide range of uses. Polyester films have good transparency and luster. Good air tightness and moisture resistance. Excellent mechanical properties. Its strength and toughness are the best among all thermoplastics. The tensile strength and impact strength are much higher than in ordinary films.

The dimensional stability allows it to be used in a variety of applications. Such as masks, laminates, film circuits, electronic insulation, carrier films, printing, and packaging. The polyester film is non-toxic and can be approved by the FDA. It can be used in areas where food packaging, disinfection, and cleaning are critical. The thickness of PET film can range from 4.5 micron to 350 micron. Single-sided, double-sided corona treatment. The color can be from transparent, super transparent, matt, opaque, white, milky white to red, yellow, black, blue, etc.

Corona treated pet film is very common products in pet film product. Corona treatment is a high frequency charge would provide both a more efficient end controllable method of increasing the adhesion and wettability (surface tension) of a plastic surface.

The result is an improvement of the chemical connection (dyn/cm) between the molecules in the plastic and the applied media/liquid. This surface treatment will not reduce or change the strength. Neither will it change the appearance of the material.

The surface tension of pet films is not sufficiently high to permit good adhesion of print ink with pet film . In case of lamination , it prevents better bonding between two or more materials. Hence, for better quality of printing, lamination and coating processes , surface tension of the plastic films should be increased. The Corona Treatment method is widely used nowadays to increase the surface tension of the pet film.

Corona Treated PET films offer polyester film products that provide excellent performance characteristics suitable for use in packaging and industrial applications.

Corona treatment can be done in one side or both sides on the pet films.One side Corona treated pet film ,both sides Corona treated pet film
