1. What is Mylar mean? / What is Mylar film?

  Mylar is a brand name that has come to be commonly used when talking about biaxially oriented polyethylene terephthalate (BOPET) polyester film, much like people commonly say Kleenex when referring to tissues.


2. Is Mylar the same product as polyester film or even just plastic film?

A:The word “Mylar” is often used to generically refer to plastic film. But:Mylar is a registered trademark owned by Dupont Tejjin Films for a specific family of products made from the resin Polyethylene Terephthalate (PET).

5.Mylar Properties

Several properties of BoPET, including Mylar, make it desirable for commercial applications:

  • Electric insulator
  • Transparent
  • High tensile strength
  • Chemical stability
  • Reflective
  • Gas barrier
  • Odor barrier

6.What is Mylar Made of

To make Mylar, super-heated polyethylene terephthalate (PET) film is put on a roll and stretched. One side is smooth, but the other is not so that it can be applied more easily as a coating to various products, such as paper.

Molten polyethylene terephthalate (PET) is extruded as a thin film onto a chilled surface, such as a roller.

The film is drawn biaxially. Special machinery may be used to draw the film in both directions at once. More commonly, the film is drawn first in one direction and then in the transverse (orthogonal) direction. Heated rollers are effective for achieving this.

Finally, the film is heat set by holding it under tension above 200 °C (392 °F).

A pure film is so smooth it sticks to itself when rolled, so inorganic particles may be embedded in the surface. Vapor deposition may be used to evaporate gold, aluminum or another metal onto the plastic.

7. Mylar uses

Mylar and other BoPET films are used to make flexible packaging and lids for the food industry, such as yogurt lids, roasting bags, and coffee foil pouches.Mylar tape,mylar coating adhesive film,silver mylar sheet.

BoPET is used to package comic books and for archival storage of documents. It’s used as a covering over paper and cloth to provide a shiny surface and protective coating. Mylar is used as an electrical and thermal insulator, reflective material, and decoration. It’s found in musical instruments, transparency film,printable mylar sheets,mylar paper rolls and kites, among other items.

Eehui Film offers a wide variety of different types, mylar mirror roll,grades, finishes and thicknesses of Mylar film.
