Polyester film brands: Mylar, Hostaphan, Melinex, Garware, Lumirror

polyester film ( PET films) is a material widely used in industry. There are a large number of manufacturers producing a wide range of products. Transparent foils are widespread, but also milky-white to white foils. Both matt and opaque polyester films are available. Black polyester films are also produced. With certain quantities it is possible to produce other colors. For this purpose, primary materials colored in the raw material are used. Polyester films colored in this way are mainly used in the food industry. Sealable polyester films are also used in the food industry.

Other special types are UV-stabilized and flame-retardant films. Polyester films are manufactured in the thickness range from 8 µm to 500 µm. The material can be supplied in widths of up to 8 m, strips can be produced from 1,2 mm depending on the thickness.

the dr Dietrich Müller GmbH trades in the following polyester film brands:

Mylar polyester film

Mylar is a transparent, flexible polyester film based on polyethylene terephthalate. This film appears milky and cloudy as the material thickness increases. DuPont Teijin Films produces these films in Luxembourg, among other places. Mylar's properties include excellent resistance to moisture and common solvents. It can be used at temperatures from -70 °C to 150 °C. Since it contains no plasticizers, it does not become brittle with aging under normal conditions.

We supply the following Mylar PET films:

Mylar A : Standard version of Mylar: PET films with balanced mechanical, electrical and chemical properties
Mylar ADS : low-shrink version of Mylar A films. Greater dimensional accuracy up to 150 °C temperature application.
Mylar C : Mechanically stable design with excellent electrical properties for capacitor manufacturers.
Mylar D : good compatibility and metallization with a slightly matt surface for optimal rolling behavior.
Mylar HS : Shrinkable polyester film for insulation and packaging purposes (FDA approval available). Use for insulating caps.
Mylar OL : Mylar films with additional equipment (heat-activated PET layer)

Alternative to mylar

As an alternative to Mylar A, the following polyester films are used.

Hostaphan Polyester Films

Hostaphan is a polyester film manufactured by Mitsubishi in Germany. The films of interest in our region are the Hostaphan RN and Hostaphan WN types. Hostaphan polyester films have extremely good properties in terms of mechanical stability, electrical strength, abrasion and temperature resistance. Excellent mechanical strength and high dimensional stability are further positive properties. These polyester films are equipped with an adhesion promoter for water-soluble printing and coatings on one or both sides.

The following Hostaphan types are available:

Hostaphan WN : white, translucent film with balanced mechanical, electrical and chemical properties
Hostaphan RN : Standard Mitsubishi polyester film
Hostaphan WO : white, opaque foil especially for the printing industry
Hostaphan BHO : black, opaque film for optical applications
Hostaphan RF : a flame-retardant 50 µm PET film (UL94 or B1)
Hostaphan CALL : a flame retardant and UV resistant film (19 µm)
Hostaphane RUV : particularly UV-stable film

Melinex polyester films

Melinex is a flexible, white polyester film with matte finishes offered by DuPont Teijin Films. The properties are a relative temperature index of 140 °C and a mechanical RTI of 130 °C. In addition, it shows better aging behavior compared to standard polyester films with a higher oligomer content. In addition, Melinex attaches great importance to high dielectric strength, low changes in dielectric values, special mechanical properties and very good resistance to hydrolysis.

We process these Melinex polyester films:

Melinex 516 : a very clear polyester film , which is pre-treated on both sides to combine good handling properties with high clarity and brilliance.
Melinex ST506 : crystal clear, high gloss, heat stabilized polyester film. The film is pre-treated on both sides for better adhesion. It can be printed with a variety of solvent based graphic inks and varnishes, silver conductive and dielectric inks.
Melinex 1311 : is a clear polyester film with anti-static properties on both surfaces for improved handling and safety.
Melinex WCW : is a translucent white polyester film with rough surface for excellent handling properties.

Garware polyester films

Garware is an Indian Polyester Film Manufacturer who also manufactures a wide range of Polyester Films:

Garware EM6 milky-white: Standard polyester film for a wide range of applications, especially in the electrical and electronics industry.
Garware EM6 LO : Milky -white, low oligomer polyester film used in the manufacture of refrigeration compressors.
Garware EM : clear polyester film for various applications

Lumirror polyester films

Lumirror is a high-performance, multifunctional film developed using Toray's advanced technologies. It is used for numerous applications in the IT field as an industrial material (for applications such as flat panel displays, as a material for liquid crystals and as a process barrier) and as a magnetic material (for products such as computer data storage, DVC cassettes, etc.). Lumirror is also often used as a packaging material.

Lumirror 40.01 : clear polyester film, available in the following thicknesses: 23, 36, 50, 71, 96, 125, 175 µm
Lumirror 45.11 : Crystal-clear polyester film with antistatic finish on both sides, available in the following thicknesses: 96, 125, 165 µm
Lumirror 60.01 : colourless, transparent polyester film, available in the following thicknesses: 125, 190, 250, 300 µm
Lumirror 60.61 : Milky white polyester film available in thicknesses: 50, 75, 125, 190, 250, 300 µm

Stamped parts made of polyester film

These polyester films and other materials are available from Dr. Dietrich Müller GmbH to cover the variety of applications for stamped parts. An extensive machine park with lifting and rotary punches forms the basis for realizing orders from small quantities to large series with several million copies.

How should the punched goods be delivered? There are various options for this: The die-cut parts made of polyester film can be supplied on a roll with self-adhesive finish or optionally non-adhesive on a roll. The options of self-adhesive individual parts or non-adhesive individual parts are also possible, as are loosely cast stamped parts or individual magazine parts.

Are you looking for a competent partner when it comes to punching? The company Dr. Dietrich Müller GmbH will not only help you with the product selection, but will also work with you to find solutions for your own combination of coating and film if a special material is not yet available. From material procurement and coating to cutting and punching, Dr. Dietrich Müller GmbH handles the entire production depth of stamping. In terms of logistics, the company will also find optimal solutions for you when it comes to delivering the stamped parts.

Both in the Automotive Industry , the cable industry, as well as the Medical Technology and the electronics industry Can be found stampings made of polyester film with regular and versatile use.

Alternatives to polyester films

If the temperature resistance of the polyester films is not sufficient, use the Teonex Q51 – PEN film, our PEI films and the polyimide films are available as technical foils covering a wide spectrum.
