Plastic film is a thin continuous polymeric material. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces.
It is used in a wide variety of applications. These include: packaging, plastic bags, labels, etc.
Plastic films are typically formed into rolls by roll slitting. Often additional coating or printing operations are also used. Films can be modified by physical vapor deposition to make metallised films. Films can be subjected to corona treatment or Plasma processing; films can have release agents applied as needed.
Typical converting processes are coating, laminating and printing. Coating technologies can include hot melt coating, gravure coating, curtain coating and slot-die coating. The most common printing techniques are flexo printing and rotogravure (gravure) printing. Both print processes are suited to high speed roll-to-roll processing.
We as a converting company will process large diameter, wide rolls of material as this increases the converting efficiency by minimising changes. On completion of the converting process the rolls may be cut into smaller rolls on a slitting machine. These rolls are then a convenient size for handling on packaging and other machines. Alternatively, the rolls may be sheeted-cut into sheets — as happens in newspaper and book printing. Further processes such as collation may occur after sheeting.
There is a huge universe of plastic film materials, ranging from film made of a simple single plastic material to film comprised of a complex structure of different materials and coatings. Plastic film can be manufactured out of various plastic resins, each with its own unique physical properties which are differently suited to different applications. Besides all the different materials it can be made out of, plastic film can be clear, colored, smooth, rough, functionally embossed, opaque or semi-transparent. So when you’re looking for plastic film for your application, our goal is to help you get to the specifics, so we can best fulfil your needs.
