发明名称 METODO ED APPARATO PER PRODURRE UNA CONFEZIONE CON IMBALLAGGIO PIU' VOLTE RICHIUDIBILE
摘要 A method and apparatus for making a reclosable package from a forming web, a covering web and a closure strip. The closure strip is indented at desired intervals and sealed at its lower surface to the forming web. A cavity is formed in the forming web after which a product is placed therein and covered with the covering web. After evacuating the space therebetween the covering and forming webs are sealed together with longitudinal and transverse seals which enclose the product and the closure strip. The upper surface of the closure strip is sealed to the covering web so that when the package is severed between the closure strip and an adjacent longitudinal seal, the closure strip may be opened for access to the product.
