POSITIONING OF THE BAG IN THE CHAMBER
The bags normally used for vacuum packaging are as a rule made from two layers of nylon externally and
food grade polyethylene internally with thickness from 90 to 140 microns, depending on the type of product
to be packaged.
For the positioning of the bag inside the equipment see fig. 3.
The product C must be perfectly in line with the sealing bar A, this is achieved by regulating the trenchers D
(these trenchers allow in fact the lining up of the product and the filling up of the chamber for a quicker
vacuum effect).
The bag B must be carefully placed on the sealing bar A in order to avoid folds which could affect the
sealing.
The bag must never be bent at the back of the sealing bar.
The bag B must have a surplus of at least 2 cm beyond the sealing bar A.
