The name "shrink film" came about because the plastic shrinks tightly to whatever it's covering when heated. Therefore, use shrink film for "shrink wrapping".
POF shrink film is made of POF which represents polyolefin. In the past, PVC (polyvinyl chloride) film was widely used for shrink wrapping, but it is slowly being replaced by POF shrink film.
What is POF?
Polyolefins are actually a group of hydrocarbons, i.e. compounds containing hydrogen [H] and carbon [C] atoms. It is usually derived from the low molecular weight components of natural gas or petroleum.
As a thermoplastic, polyolefin is popular because it is so easy to form that it can be reshaped again and again simply by repeating the heating, forming and cooling process. POF also has several other advantages that make it more secure than PVC.
There are two main types of POF - polyethylene and polypropylene. These are further subdivided into several grades for different applications.
Polyolefin shrink films are used in almost all types of applications. Essentially, it is used to protect and package a single product, or to bundle multiple products together.
It is especially suitable for packaging less rigid items such as food, stationery, cards and electronics.
Quality of POF Shrink Film
Anti-fog
durable
versatile
Seal strength
quite cheap
tear resistance
Because POF shrink film bends easily at low temperatures, it will not deform, bend or collapse thin, brittle or fragile products. This quality also provides excellent protection for irregularly shaped items.
