All the necessary information related with Bopet Film

The full form of Bopet is Biaxially oriented polyethylene terephthalate and it can be defined as a polyester film which is made out of polyethylene terephthalate or PET in a stretched manner. This Bopet Film is known for some of its positive features like high tensile strength, dimensional stability, chemical stability, aroma and gas barrier properties, reflectivity, transparency and also the notable electrical insulation. There are a large number of companies who are manufacturing such bopet and various other polyester films using different brand names. In both the U.S and UK, these films are known as Melinex, Mylar and also Hostaphan.

A little history related with such polyester film namely Bopet:

These films were developed in the middle of the year 1950s and this was done by three eminent companies namely Hoechst, DuPont and ICI or Imperial Chemical Industries. In the year 1964, the scientists from NASA first launched Echo II which was the second part of the Project Echo mission. This was mainly a 131 feet diameter balloon which was entirely constructed from a 0.35 mil Mylar film which was thick and was sandwiched between two layers of aluminum foils which are bonded together.

Some important notes related with manufacturing procedures and properties:

The manufacturing procedure of Bopet Film starts with a film of PET which is molten in nature and is extruded from a chill roll in the beginning. It previously remains in an amorphous state and then it is oriented biaxially by using the drawing process. The easiest and common way of doing these is through the sequential process when the film is first drawn inside the machine in a direct manner by using the help of rollers which are heated and then the film is rolled in the transverse direction. The opposite rolling procedure takes place inside a heated oven. It is also possible to roll the film in both directions simultaneously.

After the heating procedure is over, then the film is crystallized at a temperature above 200^oC. In order to make the handling procedure even smoother, there are some inert inorganic products which are mainly embedded inside the PET films to roughen the surface. Metalized Polyester Film can be easily metalized with the help of vapor deposition of a metal thin film like gold, evaporated aluminum and more.

Application of these films:

There are various uses of these polyester films and some of those are mentioned below:

1. For food contact applications and also for flexible packaging
2. For covering the upper layers of papers
3. For insulating material
4. For different other applications like marine, solar and also aviation purposes
5. Various fields of science
6. For different acoustic and electronic applications
7. Graphic arts
8. Other applications like in balloons, materials in kites, covering glass, theatrical effects, work as an adhesive tapes, used as valves or wind savers and more.
