Abstract
An automatic vacuum packaging apparatus which is defined by a closable frame having upper and lower sections, the lower section including a heatable platen configured with one of several patterns of transversing channels through which air can be evacuated through two separate conduits drawn into one vacuum chamber located beneath the lower platen. The upper section is closable over the lower section and has a separate variable heating element and separate peripheral attachment to the vacuum. Plastic sheets may be placed on the upper and lower frames, and an object placed between them. Then, through the electronically controlled interaction of the vacuum, heating elements, channels and closure of the frames the object may be vacuum sealed between the plastic sheets. The patterns of channels allow for the improved removal of air as the channels vary in length thus increasing the ability of the vacuum to efficiently remove over 97% of the air by concentrating the pull of the vacuum in smaller areas.
