Title
(EN) METHOD FOR FORMING BIODEGRADABLE BAGS
(FR) PROCÉDÉ DE FORMATION DE SACS BIODÉGRADABLES
Abstract
(EN)
A method is disclosed for forming a package of a non-weldable material on a vertical form- fill-seal (VFFS) machine or a horizontal form-fill-seal (HFFS) machine. The method comprises providing a continuous web of the non-weldable material having exposed areas of adhesive. In an embodiment the method is implemented on a VFFS machine that has a fill tube designed and configured to avoid interaction with the adhesive exposing areas of the web. In a preferred embodiment the adhesive exposing areas are formed by providing a repeating pattern of sets of apertures in the web, and fully covering each set with a label that is coated with adhesive.
(FR)
L'invention concerne un procédé de formation d'un emballage d'un matériau non soudable sur une machine à forme verticale de remplissage-scellage (VFFS) ou une machine à forme horizontale de emplissage-scellage (HFFS). Le procédé consiste à fournir une bande continue du matériau non soudable ayant des zones découvertes d'adhésif. Selon un mode de réalisation, le procédé est mis en œuvre sur une machine VFFS qui comporte un tube de remplissage conçu et configuré pour éviter une interaction avec les zones d'exposition adhésive de la bande. Selon un mode de réalisation préféré, les zones d'exposition adhésives sont formées en fournissant un motif répétitif d'ensembles d'ouvertures dans la bande, et en recouvrant complètement chaque ensemble d'une étiquette qui est revêtue d'adhésif.
