Definitions of Industrial Shrink Films
This article will guide new or existing users of industrial shrink film in respect
of the definitions of industrial shrink film so that they may have a ready classification
for industrial shrink films.
Transit Shrink Films
Polythene (PE) Industrial Shrink Films
The most widespread industrial shrink film is low density polyethylene, more commonly
referred to as polythene or PE.
The principal use to which PE is put is as a transit medium. It allows packs to
be wrapped individually or collated and offers the best combination of protection
and unit cost when compared with the alternatives.
PE industrial shrink film is used on a vast range of products, from radiators and
work surfaces to collation of cans and jars and the individual shrink packaging
of cartons and products themselves, such as pizza.
Industrial shrink film applications do have overlap between transit and display
industrial shrink film where there is a requirement for the enhanced presentation
offered by display, and equally, where the advantages of display are not required.
The industrial shrink wrap ranges do not overlap totally as a fundamental transit
requirement in the normal way can be satisfied only by PE industrial shrink film.
Display Shrink Films
Polyolefin (PO) & Polyvinylchloride (PVC) Industrial Shrink Films
Display industrial shrink films are categorised into Polyolefin PO and polyvinylchloride
PVC industrial shrink films.
Polyolefin Industrial Shrink Films
Polyolefin industrial shrink films have multiple layers of PE and polypropylene
PP and may be irradiated for extra strength, and treated for hot slip or anti-fog
properties.
Polyolefin industrial shrink films are formulated to offer a wide sealing
and shrinking window so that they can be readily used on manual, semi and fully
automatic machinery.
Polyolefin industrial shrink films are so versatile so that they are the
first choice when using display industrial shrink films; PO industrial shrink films
will generally offer an excellent solution to an industrial shrink film requirement.
In addition to these industrial Polyolefin shrink films ,
Kempner also offer other technically advanced Polyolefin shrink films .
PVC Industrial Shrink Films
PVC
industrial shrink films have been largely superceded by Polyolefin (PO) industrial
shrink films.
PVC industrial shrink films have particularly easy sealing and shrinking
features but they are inferior to PO industrial shrink films in the areas of strength,
low temperature flexibility and equipment maintenance requirement. PVC industrial shrink films
continue to be used on very flexible packs, particularly heat sensitive products
and, generally, on older equipment.
PVC
shrink film is also used with less plasticiser in the form of semi-rigid
industrial shrink film where its shrink properties give its application, substituting
BOPP overwrap film, the advantage of a shrink finish.
In addition to theses industrial PVC shrink films , Kempner also offer designer
presentation
PVC shrink films .
