L sealer working theory

Automatic L type shrink wrap sealer is designed to make loose non-rigid bags over the product by sealing the film edges (seal only) with a 90°L  type right angle sealing knives. This  to make packs with the film clinging to the product by sealing the heat shrink film over the product and then applying heated air around the pack to shrink the film (seal and shrink).

The machine can be used with a variety of shrink films with thickness of 15 microns to 75 microns. The film used must be centre-folded and can be pre-perforated. In case of non-perforated film, the machine is provided with perforator pin-wheels to make the air evacuation holes on the film during the packing process. The machine is capable of production speeds of up to 2000 packages per hour depending on the product size and type of film used but mostly it will use POF shrink film to meet the applications of packaging.
