Metallized boPET film, 32 layers of ~14 μm thickness each. BoPET (biaxially oriented polyethylene terephthalate) is a polyester film made from stretched polyethylene terephthalate (PET) and is used for its high tensile strength, [1] chemical stability, [1] dimensional stability, [2] transparency [1] reflectivity, and electrical insulation.

Plastic films are usually thermoplastics and are formed by melting for forming the film. [2] Cast – Plastics extrusion can cast film which is cooled or quenched then wound up on a roll. Extruded film can be stretched, thinned, or oriented in one or two directions. Blown or tubular process forces air into an extruded ring to expand the film ...
The most common and highest volume produced polyester is Polyethylene terephthalate (PET), which is an example of a saturated polyester and finds utilization in such applications as fibers for clothing and carpet, food and liquid containers (such as a water/soda bottles), as well as films. [11] In unsaturated polyester (UPR) chemistry ...
Acetate can also be spliced with film cement, while polyester can only be spliced with tape or an ultrasonic splicer, so polyester is hard to edit. Acetate film does not burn under intense heat, but rather melts, causing a bubbling burn-out effect — this can be seen simulated in films such as Persona (1966), Two-Lane Blacktop (1971) , The ...
