Abstract
Produce packages are stacked onto a pallet having an underlying gasproof plastic sheeting. The loaded pallet is placed on a rotatable table and a plastic bag is lowered over the produce which has its lower edges located partway down over the upturned portions of the plastic sheeting and onto the rim of the pallet. Two rolls of tape mounted at different heights on vertical spindles closely adjacent the table provide two tape strips with an edge portion overlapping. An idler roller joins the two strips of tape together in a single composite tape strip. The composite tape strip is applied by a pressure roller along the lower edge of the plastic bag and the pallet. After a full revolution of the table is completed, the tape is cut and the bag is completely sealed to the pallet. A lever arm on the pressure roller is spring-loaded to maintain the tape compressingly contacting the plastic bag and pallet throughout the full range of table rotation. Artificial gaseous environment is then provided to sealed container.
