Wrapping and Sealing a Product
- Overwrapping Machine
- A wrapping machine which wraps a product or group of products in flexible packaging material with a series of folding, heat sealing or gluing operations.
- Roll Wrapping Machine
- A wrapping machine which wraps a cylindrical product or group of products, in a series of folding, heat sealing or gluing operations, to form a roll shaped pack. Common applications are packing biscuits or some types of confectionery.
- Foil and Band Wrapping Machine
- A wrapping machine which wraps a product in aluminium foil before applying a paper band to complete the pack. A common application is in some styles of chocolate confectionery.
- Pleat Wrapping Machine
- A machine which gathers and folds flexible material around a product and then seals at one point using a label. A common application is soap wrapping.
- Stretch Film Wrapping Machine
- A wrapping machine which pulls a web of stretch film around a product or group of products before gathering and heat sealing the film edges below the product. Usually used for fruit.
- L-Sealing Machine
- A wrapping machine which uses a thermoplastic film folded in half along its length. Products or a group of products are placed between the two halves of the film before it is sealed with an L-shaped sealing bar to produce a fully enclosed pack sealed on three sides. Very common in manual or low volume applications where products may vary in size, shape and quantity, such a stationery or greeting cards. It is often used in conjunction with a shrink tunnel.
- Fold Over Wrapping Machine
- A wrapping machine which folds a web of thermoplastic material around a rigid pack, overlapping but not sealing the edges of the film under the pack while the pack is being transported horizontally. Transverse seals are then made in front and behind the pack before the pack is passed to a shrink tunnel where the material shrinks and the overlapped material under the pack forms a seal. This is an unusual machine most commonly used for bundles of wood.
- Skin Packer
- A machine which seals products placed on a cartonboard blank by placing a thermoplastic film over the entire surface, which is heated so that the film forms a skin tight seal around the product and adheres to the surface of the cartonboard blank. Common in DIY and small building and electric products. It should not be confused with a form of Blister Packing which uses preformed rigid plastic components to attach the product to the cartonboard.
