(54) Handles for wrapped packages


(57) An article (2) is wrapped in three plastics films (1, 4, 5) which are secured together at or near the bottom of the article by heat sealing using heat sealing jaws (9 and 13). The films (1, 4, 5) are then conformed to the shape of the article (2) by e.g. heat shrinking using hot air blower (16). One of the films (5) has different properties from the others and conforms differently so that it forms a handle for the wrapping. Strength of attachment of the handle is achieved by the combined effect of the heat seal (3) and the "tack" of the plastics films (4, 5) along the sides of the article.
