There are many types of stretch wrap film. Each
has qualities that are particularly suitable
in addressing the specific needs of your stretch
wrapping operation, such as load size and type,
performance requirements as well as budget.
The following lists some of the most important
types of stretch film, their attributes and
applications. Click on a stretch wrap film below
for details.
 Cast
Stretch Film
Cast stretch film also called cast film or cast
wrap, is manufactured using the cast extrusion
process. Typical characteristics of cast stretch
films are: excellent optics, clear, glossy,
superior tear resistance, quiet unwind, consistent
cling and consistent film thickness.
Blown Stretch Film
Manufactured using the blown film extrusion
process and also referred to as blown film.
Typical blown stretch film characteristics are:
poor optics, hazy, dull, excellent puncture
resistance, very noisy unwind and high force
on load.
Hand Stretch Film
Stretch film designed specifically to be applied
manually is referred to as hand stretch film.
It is also referred to as hand film, hand stretch
wrap, hand wrap or manual pallet wrap. It is
typically utilized in lower capacity packaging
operations. However the efficiency of manual
stretch wrap packaging should be regularly re-evaluated
against potential benefits of upgrading to a
machine wrapper. Choosing the right stretch
applicator will result in more efficient and
cost effective packaging operations.
Machine Stretch Film
Stretch film designed to be applied with a stretch
wrap machine is referred as machine stretch
film. It provides many advantages over hand
film including: faster and more efficient packaging,
reduced packaging material costs, safer application,
more secure loads and more. Common machine stretch
film types: cast machine stretch film, blown
machine film and converted films.
 Converted
Films
Converted film is film that is stretched
before wrapping a load. Converted film benefits
include:
Reduced amount of film used, so film costs
are greatly reduced
Requires fewer revolutions to wrap a load,
saving time, more efficient
Less packaging film means less waste to clear
and dispose
Converted films are recyclable
Converted film is strong, consistent
Specialty Stretch Film
Specialty stretch films are designed to answer
very specific packaging needs that more general - purpose
stretch packaging solutions cannot accommodate.
A small sample of some specialty stretch packaging
films is listed below.
