A shrink wrapping apparatus, and associated process, includes a housing (turbine) having a wall forming a passage dimensioned to receive the associated container assembly and associated sleeve. The passage has an inlet and an outlet spaced therefrom, and the inlet is located vertically above the outlet such that the associated container assembly and associated sleeve move from the inlet toward the outlet. A steam path communicates with the passage to provide steam from an associated steam source to at least a portion of the passage in order to shrink wrap the associated sleeve on the associated container assembly as the container assembly and sleeve move downwardly through the passage and the steam naturally rises upwardly through the passage.

Bag-sealing apparatus is provided for heat-sealing a bag. The apparatus has a heater arrangement operable to apply heat to heat-seal an open end of the bag. A bag detector detects the location of the bag relative to the heater arrangement. The heater arrangement is formed of plural heater portions. The heater arrangement is operable such that only the or each heater portion that overlies the bag as detected by the bag detector is caused to operate to apply heat to the bag.
