ABSTRACT:
The meat packaging machine of the present invention is designed to vacuum pack meat products between two webs of heat sealable thermo-plastic material. One web of each package is formed with at least two pockets connected by and bounded by a sealing flange extending outwardly therefrom. The second web which closes the pockets also extends over the sealing flange and the entire interface between the two webs is heat sealed to prevent migration of meat juices. The machine includes a sealing head and a sealing die mounted one on either side of the sealing plane. Heated sealing members are located in the sealing head and in the sealing die which, when the head and die are in the closed position, are disposed to engage the first and second webs therebetween to effect a heat seal over the entire sealing interface of the webs.
