Abstract
The present invention describes an improved side-sealing machine for use with heat sealable films. Briefly, a cutting and sealing element is located between a set of cooperating guide and alignment members. The downstream guide and alignment member also includes a compression mechanism. This compression mechanism serves to compress the seal created upstream, and to draw the heat away from the film. In some embodiments, the downstream guide and alignment member also serves to separate the film into a surplus portion and a remaining portion, where only the remaining portion is subjected to compression.
