ABSTRACT:
An apparatus which produces consistent transverse seals in a continuous shrink film packaging operation to package trays is disclosed. The seals are consistent as a result of constant sealing dwell-time, and are also consistently positioned with respect to the trays. Neat, leak-free packages are produced after shrinking. The apparatus is particularly useful for packaging trays of moisture-containing food products such as chicken parts.
