HEAT SEALERS

Heat Sealers are a vital pieces of equipment when packing products in foil pouches and foil rolls, as they help form a robust air-tight seal.

They work by heating-up the foil/polymer laminate, to a point where the plastic layer on the inside of the foil (normally a LDPE or HDPE polymer*) begins to melt. The heat sealer then compress both of these two melting surfaces together, in a pair of ribbed jaws (or via a pair of guide wheels and a long heated groove).

The ‘ribbed jaw’ format of Heat Sealers are also known as ‘Heat Sealing Tongs’. The other format (with the pair of wheels) is referred to as a ‘Heat Sealing Machine’.

Heat Sealing Tongs are normally recommended for low-volume or lower-speed packing lines, where operators are individually sealing the 4th (open) side of pre-made foil pouches.

Heat Sealing Machines are normally used with large/long foil rolls. Here, the foil (from the roll) is cut to size, and sealed on all four sides, to make a pouch (or sack).

Heat Sealers must be used in all industries and applications that use aluminium foil packaging. This includes the Healthcare, Pharmaceutical, and Nutraceutical sectors… plus the Food, Defence, and Aerospace industries. In essence, it’s any application that requires an item to be securely sealed, for the guarantee of the product’s shelf-life.

Some applications require specialist heat-sealing equipment that can also record, time, temperature and a unique number; to guarantee that this specific sealed foil bag can be traced and can be validated. Heat Sealers can be GMP (Good Manufacturing Process) compliant, and they can operate in a clean room environments.
