Abstract

Method for forming a skin-shaped vacuum pack characterized in that it includes the steps consisting of: Placing an article to be packed between a top sheet and a bottom sheet of plastic film, the bottom of the article resting on the bottom sheet; Pushing, by means of a sheet positioning device, the upper sheet to the first packaging forming position in which said upper sheet is in contact with the upper part of the article, it is situated very close to all the lateral parts of the article and it is separated although very close to the lower leaf; Extracting the air from the space formed between the upper and lower sheets while the upper sheet is in said first packing forming position; Displacing, by means of the sheet positioning device, the upper and lower sheets relative to one another and to a second packaging forming position in which separate portions of the upper sheet are in welding contact with opposite parts of the lower sheet, leaving however not welded other opposite parts separated from the upper and lower sheets; y Pushing by means of an air pressure exerted on the outer surface of the upper sheet the upper sheet to a third packing forming position in which said other opposite and separated parts of the upper and lower sheets are in welding contact and other parts of the upper sheet are in skin contact with the upper and lateral parts of the article thus forming a hermetic vacuum package in the manner of a skin.
