Polywrapping - What is it?
Polywrapping is an automated process of wrapping an item in a clear or printed polythene film. Polythene wrap is fed from reels under and around a product. The two edge are then brought together and heat sealed together and crop sealed at the top and bottom to create a "pack".
Items that can be polywrapped include: direct mail, books, brochures, catalogues, CDs, guides, magazines, periodicals etc.
The size of items which can be polywrapped will vary from machine to machine but as a general rule items as small as 2pp A6 card or up to 60 mm A3 items are within tolerances. A number of items of similar of smaller size to the original can be machine fed onto the polywrapping line. Because these items are placed on top of the product they are called onserts.
Polythene can be recycled at a few accepting centres and used to make such items as garbage bags, fertilizer sacks, chairs, benches, tables, pallets etc.
The use of polythene has several advantages over envelopes:
Polythene is lighter and significantly cheaper than a C4 paper envelope. A reduction in weight could mean the addition of an additional leaflet or promotional item at no extra postage cost.
Clear polythene allows recipients to view the contents (such as a magazine cover) prompting them to open immediately if the item is of interest or expected (i.e. subscription magazine)
A pre-designed opaque film with an address window, the use of spot or full colour can create a more immediate and professional impact.
