What is Polyolefin (POF) Shrink Film?
Polyolefin shrink film is a thermoplastic polymer made primarily from polyethylene (PE) and polypropylene (PP). It is a clear, thin, and flexible plastic film that shrinks tightly around an object when heat is applied. POF is available in single-layer and multi-layer forms. You must choose the best one under the expert guidance of the Bagla Group according to your product requirements.
How Does POF Shrink Film Work?
The process of using POF shrink film in food packaging involves 4 major steps:
Wrapping – The product is wrapped in the film using a different machine, such as L-bar sealers, manual sleeve wrappers, or high-speed flow wrappers.
Sealing – The film is heated to form a complete wrap around the product as per the product’s shape.
Shrinking – It is passed through a heat tunnel (or subjected to a heat gun) where the film contracts, forming a tight, protective layer.
Cooling – Once it cooled, the film gained its new shape, creating a tamper-evident, appealing package.
This simplest integration of automation and film behavior is one of the biggest reasons POF is widely used in the food production industry.
