Packaging Automation: Vacuum skin pack option for tray sealers

Designed for meat, poultry and fish packaging, Packaging Automation’s vacuum skin pack option for its eclipse range of tray sealers creates high-visibility vacuum packs on pre-formed shallow trays to improve convenience, protection, and freshness, as well as provide less waste, reduced pack weight, and increased productivity, at a sealing rate of 75 packs/min.

The unique, fully electrical eclipse SL4 tray sealer can reduce the user’s running costs by 90%, unlike the pneumatic/electric hybrids, according to the company. It requires zero air for full operation. The machine has many capabilities including the option for skin packing, gas flushing and vacuum gas flushing. Ultra lightweight and quick release tooling is offered as standard on all eclipse machinery.

The eclipse range also offers the inside cut option and the capability to run sealing film as thin as 17 micron, which is said to reduce film usage by 20% when compared to existing tray sealers.
The SL4 includes an inbuilt tool loading system which, when combined with the ultralight tools, allows manual tool changes and accurate docking of electrical and gas connectors, removing the need for a mobile loading jig.

The top tool comprises single impression removable cartridges that enable continued operation during repairs and maintenance. Spare cartridges can be supplied to allow full capacity operation at all times; a complete tool changeover can be achieved within two minutes.

Simplified operation is provided by a Minimal Operator Interface that helps eliminate operator errors and improves efficiency by pre-setting all machine parameters, including tool recipe settings and pack handling, at the touch of a button.

Other features of the eclipse range include tooling heater mats with an integrated thermocouple. Manufactured from a waterproof material, these mats heat up 30% faster and have a significantly longer life than materials previously used. To save on downtime, a Pack Crush Protection system prevents smashed packs when incoming trays are not orientated properly, and quick release cutting blades allow for replacement in seconds.

The eclipse range also offers modified atmosphere with either gas flushing or vacuum gassing for longer shelf life; energy saving features, such as automatically switching to stand-by when not in use; and, for the fresh produce sector, clip-on lids can be replaced by pre-punched film allowing pack contents to breathe.
