ABSTRACT:
A method of installing a continous moisture proof essentially disposable film liner within a convertional cargo trailer to protect moisture sensitive cargo during shipment. A polyolefin bag is inflated directly into an empty tractor trailer by attaching the bag opening to the outlet of a blower and blowing a gentle stream of air into the bag as suction is applied to the interior of the cargo trailer between the sidewalls of the trailer and the expanding polyolefin bag. In this manner, the bag inflates from the rear of the trailer forward, while the air trapped between the bag and the inside walls of the trailer is removed by suction, thus sealing the bag to the interior of the trailer. Once the bag is properly inflated and in contact with the inside of the trailer, it has been found that it tends to remain in place for sufficient time to load the cargo, even without continued use of the blower.
