PACKAGING APPARATUS AND METHOD OF EXPELLING GAS

摘要

A packaging apparatus comprises a pressure chamber; an actuator configured to move the pressure chamber between a second position, in which the pressure chamber houses a package, and a first position, in which the package is unconstrained by the pressure chamber; and a pressuriser configured to increase the pressure within the pressure chamber to greater than the pressure outside of the pressure chamber. Gas is expelled from the package. The package may then be sealed and shrunk in a heat tunnel.
