The most common stretch wrap material is linear low-density
polyethylene or LLDPE, which is produced
by copolymerization of ethylene with
alpha-olefins, the most common of which
are butene, hexene and octene. The use of
higher alpha-olefins (hexene or octene) gives rise to enhanced
stretch film characteristics, particularly in respect of elongation
at break and puncture resistance. Other types
of polyethylene and PVC can also be used. Many
films have about **0% stretch at break but are only stretched to
about **0 – **0% in use. Once stretched, the elastic recovery is
used to keep the load tight.These machines offers safety for the
products. There are two methods of producing stretch wrap. 1)
Blown: the resin is melted and blown out, it is air-cooled. This is
a slower process but provides for higher quality in all the areas
listed below. The cost of production is also higher due to the
quantity that can be produced per hour. 2) Cast: the film is passed
over cooling rollers. This makes the cooling process quick. The
quality is not as good as blown but more can be produced in an hour
lower costs.
Â
Manual (or Hand) Wrappers:
Extended Core:Â An extension of the film's core serves
as a handle for wrapping; this type of wrapper offers little
stretch control and is hard on hands. Mechanical
Brake:Â A simple structure supports a film roll and a
mechanical brake system provides resistance creating stretch of the
film. Pole Wrappers: Similar to the Mechanical
Brake system, but the roll and brake are at the end of an
extended pole, creating an ergonomic design which eliminates the
need to bend to wrap the bottoms of loads and strain to reach the
tops of loads. Semi-Automatic Wrappers: Turntable
Wrappers:Â The load to be wrapped sits on a turntable which
spins the load relative to the film roll, which is housed in a
carriage which can move up and down a fixed "mast". Stretch is
achieved by rotating the load at a faster rate than the film is
fed. Orbital Wrappers:Â The film is housed in a carriage
on a vertical ring, the load is fed horizontally through the eye of
the rotating ring, applying film to the load. A variation of an
orbital stretch wrapper is a horizontal ring system, in which the
load remains still while a horizontal ring is rotated around the
load and moves up and down vertically relative to the load, similar
to a rotary arm stretch wrapper. Rotary Arm
Wrappers:Â In this system, the load remains still while a
rotating arm turns around it wrapping the load. This system is used
for light loads or for speeds which would otherwise cause the load
to topple due to high rotation speeds.
