ABSTRACT:
Apparatus for packing commodities such as meat or bacon into bags of flexible thermoplastics film material comprises a vacuum chamber and sealing means arranged to hold closely together without application of pressure a band of bag material extending across the neck of the bag and applying heat to fuse the band of bag material and form a fluid tight seal. The vacuum chamber may include heating means so that after sealing the bag may be inflated off the commodity and thereby heated prior to collapse into close engagement with the commodity.
