Shrink wrap is commonly used as an overwrap on many types of packaging, including cartons, boxes, beverage cans and pallet loads. A variety of products may be enclosed in shrink wrap to stabilize the products, unitize them, keep them clean or add tamper resistance. It can be the primary covering for some foods such as cheese, meats,vegetables and plants. Heat-shrink tubing is used to seal electric wiring. Invention relates to packaging for heavy coils of strip material, and in particular to a packaging system that includes a skid supporting a heavy coil of strip material and stretch wrap plastic roped around the base of the coil and the corners of the skid.
The package includes means for increasing the friction between the coil and the skid and preferably includes means for reducing damage to the stretch wrap material and the coil during transport.The wrapping can be further strengthened by glueing the outer layers together, either with cold or hot glue.Since the cost of hot glue is steadily falling, it is increasingly replacing the cold glue formerly used, which is difficult to handle and not very popular among the personnel operating and servicing the wrapping machine.
Applications Of Shrink Wrap
Scaffold wrap containment of buildings/bridges
Marine shrink wrapping of boats and other vehicles
Industrial shrink wrap containment of large plant equipment/components
Building temporary shrink wrap structures for storage or other business operational uses
Functions Of Stretch Wrap
Protects from frigid conditions
Efficient storage after handling of goods per unit load
Degree of resistance & tampering to the package pilferage
Improved stability of packages & products, forming the unit load
