ABSTRACT:
The invention provides a method of vacuum packing by defining a "dummy product" 17 alongside a product article 14 on a support sheet so that any "webbing" 18 is to the side of that projection 17 which faces away from the adjacent product article 14. That projection 17 can subsequently be trimmed to leave a webbing-free pack. Cutting down webbing reduces the risk of leakage of the pack. Preferably the height of the projection 17 is adjusted in response to the height of a product article 14 so that the extent of such webbing 18 is at a minimum.
