Thanks to continuous motion; for both the side and transverse sealing,
the time of contact
between the sealing bar or point and product on the “RVP” is longer than
on the conventional intermittent motion machine. This allows a higher
quality seal, even at high speeds and at a low temperature of 125C
resulting in a) perfect sealing without risk of shrink zones of the
product, b) low energy consumption and c) low heat development.
the transverse and side sealing are carried out in continuous motion,
allowing additional time and better sealing quality. The transverse
sealing can be carried out on the lower side of the product or also on
upper lug chain unit can be lifted, ensuring easy access to the
machine. The upper lug chain unit ensures perfect positioning of the
product on the machine during the transport cycle.
