"Shrink wrap" is a common term that you would
definitely come across when it comes to packaging. It is an effective method to
store and transport the items easily at an affordable cost. The shrink wrap
film is usually made of PVC or polyolefin.
The general wrapping method is the same, irrespective of the
size of the item that needs to be wrapped. You can simply measure the shrink
wrap film, spread it over the item that is to be packed and apply the heat to
the film surface. This causes the film to shrink and stick to the item that
ensures a secure packaging.
DIY procedure
You can follow the same procedure for a DIY procedure of
shrink wrap packaging with the help of any hair dryer and the film bought from
a nearby shop. This is good for casual two or three wrappings but to wrap more
items, it is advisable to invest in some good shrink wrap machines.
Traditionally, shrink wrap equipments were used to pack
DVDs, CDs, tapes, software boxes and many other things. Besides this, now one
can also pack gift baskets, food items, invoices, soaps and documents in the
shrink wrap film.
Shrink wrap machines
Earlier, shrink wrapping machineries were usually found in
industrial warehouse or factories. They were cumbersome machines are required a
lot of people who can operate it. But this is not the case anymore! Small
shrink wrap machines are now available for use by individuals and small
businesses. These are quite inexpensive and shrink film is also easily
accessible at cheaper prices nowadays.
Two kinds of shrink wrap sealers
At present, there are two kinds of machines that are
available for shrink wrap: L-bar and I-bar shrink wrap machines. It isn't very
difficult to set up these machines.
From low until medium volume of shrink wrapping, I-bar
machines are most suitable. This kind of sealer machine utilizes a single bar
for sealing. The bar is taken down so as to cut down the required area of the
film. Heat gun is then employed to make the film shrink and stick to the item,
thereby sealing it.
On the other hand, L-bar sealers or shrink wrappers are
effective for middle to high volume of wrapping by the shrink film. Hence, they
are more suitable for large business companies. As the name suggests, this kind
of sealers make use of a sealer bar that resembles in shape to the English
alphabet "L". This bar can easily cut the film for packaging, in a
single pass.
Further, the film is made to shrink onto the item with the
help of a heat gun or heat tunnel. Heat tunnel makes the process of shrinking
faster as compared to the heat gun. Hence, you can find several L-bar sealers
that have an in-built tunnel for heat. So, bring a shrink wrap sealer today and
say goodbye to the hassles of packaging at once.
