LS-975 automatic tray sealer

The LS-975 is an in-line automatic tray sealer: trays come in on a belt, are sealed with film —with or without modified atmosphere— and leave on the outfeed belt towards the next station. The work is continuous and there is no need for an operator loading and unloading moulds, which translates into more units per hour and uniform sealing tray after tray.

It should not be confused with the LS-1375. Both are in-line models with MAP, but they play different roles: the LS-1375 is the benchmark for sustained high output and the LS-975 is the sweet spot for medium output. It delivers consistent sealing without the need for a high-capacity line and changes format by fitting the mould for each tray, which makes it a good entry point for anyone packing several products.

Compared with the semi-automatic MAP tray sealer, the step up is one of organisation. The semi-automatic machine depends on the person loading the mould and suits short runs; the LS-975 sets its own pace and integrates with filling, checkweighing and labelling. It is the logical step when the semi-automatic machine has fallen short but volume does not yet justify the larger model.

Modified atmosphere replaces the air in the pack with a gas mixture that slows oxidation and microbial growth. It extends shelf life, reduces waste and returns, and widens the distribution and export radius. If your product turns over quickly and does not need it, the LS-975 also seals in normal atmosphere. In both cases, tray, film and mould are chosen together: the tray is defined according to the machine, not the other way round.
