Proseal has further extended its
range of vacuum tray sealers with the
launch of a model specifically
designed for skin packs.

The Proseal GT1VS features a
servo-driven infeed conveyor and
high accuracy tray positioning
system and accepts randomly spaced
trays in all types of materials at
sealing speeds of up to 24 packs per
minute depending on the product.

Skin packs feature a special film
that seals to all surfaces of a tray –
rim, sidewalls and base – to tightly
cover the contents. The packs have
been used predominantly for fish
products in the past but are now
being used for other foods such as
ready to cook meals, game, meat and
sausage products, and mini joints.

Wrapping the seal around the
contents means products can be
vacuumed packed for extended shelf
life without the need for gas flushing.

As there is no gas headspace needed,
tray heights can be reduced, thus
saving on packaging materials. The
sealing system also means product
can extend over the height of the
tray. Benefits are said to include
lower weight and reduced handling
and storage costs for the packs, and
the minimising of food waste.

Skin packs are said to offer
enhanced on-shelf presentation,
enabling products to be clearly seen;
packs can be placed upright to
maximise shelf space. Tight
seals also eliminate leakage for
products containing sauces.

The GT1VS incorporates a special
auto connect tool docking facility,
with lead-less and hose-less
connection of both gas and
electrical supply, to enable tool
changes to be carried out in minutes.
