发明名称 Method of applying tear strip to pack
摘要 The method involves packaging a product in an envelope of a heat shrinkable film, and then applying shrinking heat to the envelop. The heat shrunk pack (3) is advanced (along a belt conveyor 5), passing an adhesive applicator (9) which applies a strip (21) of hot melt adhesive to the top of the pack. Then the pack with its adhesive strip is advanced (by a belt conveyor 11) passing a tear strip application station (13) where a tear strip or label (23) is applied over the adhesive, with a free end (24) of the tear strip or label non-adhered and forming a pull-tag to be grasped and removed for ripping open the pack. The adhesive extends along and close to a seal (34) of the pack, and has bond strengths to both the tear strips and the pack greater than the tear strength of the pack.
