Shrink Wrapping Equipment
PPMA information about shrink wrapping and the machinery and equipment used in the process of overwrapping.
- Shrink Tunnel
- A machine which shrinks a 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. Used where the thermoplastic needs more heating time than a tunnel provides and a more constant heat to complete the shrinking process. Usually used for low cost and low speed operations.
- Shrink Gun
- A manually operated device in the shape of a gun which uses a flame or hot air stream to shrink thermoplastic film around large or difficult shaped products or where it is not convenient to use a machine for example on a building site or open area of a warehouse.
- Shrink Frame
- A machine which shrinks thermoplastic film around a product or group of products as it moves over the surface of the product. This is used for regular shaped larger items e.g. doors, radiators, double glazed windows or where long products such as timber or plastic pipes need to be grouped together for transportation.
- Dip Tank
- A machine which uses a tank of hot water to shrink a thermoplastic film around a product by dipping it in hot water. This is used for cheese because it limits the temperature rise of the product.
