Packaging Terms Explained



Wrapping Machines

Packaging machines which wrap a flexible packaging material e.g. paper, aluminium, plastic film, around a product or groups of products.

Wrapping Machines Which Partially Wrap Products

Banding Machine: A wrapping machine which wraps a band of material around a product or group of products and secures it with adhesive or by the application of heat.

Sleeve Wrapping Machine: A wrapping machine which wraps a band of thermoplastic material loosely around a product or group of products, before the pack is passed through a shrink tunnel to form a shrink-wrap pack. The band may be formed from one or two reels of film.

Stretch banding machine: A wrapping machine which wraps a band of thermoplastic film tightly around a product or group of products.

Stretch film bundling machine: A wrapping machine which wraps a web of thermoplastic tightly around a product or group of products, in a series of turns while the product is conveyed through the machine.

Wrapping Machines Which Form a Complete Wrap Without Sealing

Fold wrapping machine: A wrapping machine which wraps a product in a deformable material e.g. aluminium foil or paper, in a series of folding operations.

Edible fat/butter wrapping machine: A fold wrapping machine in which butter or edible fat is extruded, cut to size and then wrapped in a deformable material.

Twist wrapping machine: A wrapping machine which seals the open ends of the wrap by twisting.

Wrapping machines which form a complete wrap with sealing

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.

Foil and Band Wrapping Machine: A wrapping machine which wraps a product in aluminium foil, before applying a paper band to complete the pack.

Pleat wrapping machine: A wrapping machine which gathers and folds flexible material around a product and seals it at one point by applying a label.

Stretch film wrapping machine: A wrapping machine which pulls a web of stretch film around a product, before gathering and heat sealing the film edges below the product.

L-sealing machine: A wrapping machine which uses thermoplastic film folded in half along its length. Products or groups of products are placed between the two halves of film, before the film is sealed around the product with an L shaped sealing bar, to produce a fully enclosed pack, sealed on three sides.

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.

Skin Packing Machines:

Wrapping machine which seal products placed on carton board blanks, with a web of thermoplastic film which is heated and then sealed around the product.

Shrinking Equipment:

Shrink tunnel: A machine which shrinks thermoplastic film around a product or group of products, as they pass through a heated tunnel. The heating medium may be hot air, radiant heat, hot water or steam.

Shrink Oven: A machine which shrinks thermoplastic film around a product or group of products, in a heated chamber.

Shrink frame: A machine which shrinks thermoplastic film around a product or group of products, as it is moved over the surface of the product.

Dip tank: A packaging machine which uses a tank of hot water to shrink thermoplastic packages by dipping them in the water.
