SHRINK FILM Shrink film is a material made up of polymer plastic film. When heat is applied to this material, either through use of a heat shrink machine, heat tunnel or gas gun, it shrinks around whatever it is covering to create a tight, sealed package. It is primarily used as a protective wrapping for merchandise or food items, and can also be used to wrap and secure pallet loads.
available with specific mechanical and barrier properties for shrink wrapping food.
The most commonly used shrink film is polyolefin. It is available in a variety of thicknesses, clarities, strengths and shrink ratios. The two primary films are either cross-linked, or non cross-linked, and come in two basic varieties – single-wound (flat) and centrefold. Polyolefin can be easily identified by its stretchy properties. It produces little odour and can be used with most shrink wrap systems. It is also ideal for bundling multiple products together. Other shrink films include PVC used for non-perishable goods, and several other compositions. Co-extrusions and laminations are
• Versatile - can conform to almost any shape or size. • Inexpensive. • Has high clarity to allow items to be viewed and enhances shelf presentation. • Protects products from dirt and dust. • Provides impact and abrasion protection. • Provides leakage resistance and containment. • Tamper-evident. • Material savings versus using boxes, as less film is needed to create a package. • Can be printed on.
BENEFITS Shrink film has a few key advantages:
B & A FILM Building and Agricultural (B & A) film is a general purpose polythene film on rolls in varying lengths, widths, thicknesses and is available in black or natural. It is used mainly as a moisture barrier for concrete flooring on building sites, in horticultural and agricultural industries as a weed control, and as a greenhouse or growing tunnel film. Snell stock three types of B & A film, as follows:
Single Wound Sheet The width of the film is the same as the width of the roll. Centre Folded Sheet The width of the film is twice the width of the roll once opened out. Fold edge
Gusset Centre Sheet
Open edges
The width of the film is four times the width of the roll once opened out.
THE SHRINK FILM MARKET IS PROJECTED TO REACH 2.53 BILLION US DOLLARS BY 2020. *http://www.marketsandmarkets.com/PressReleases/shrink-film-beverage-multipacks.asp
