Sheet packaging material, of the type used for packaging objects on automatic packaging machines where the material is supplied in very long lengths on reels, where said material may be a single or multi layer material, where means are provided for determining where cut-off lines shall be placed, where cut-off lines indicate sections where the material will be cut when separating the packages from each other after the material has been formed into a package, and where one or more substantially parallel longitudinal slits are provided across said cut-off lines.
B65B 61/02 - Auxiliary devices, not otherwise provided for, for operating on sheets, blanks, webs, binding material, containers or packages for perforating, scoring, or applying code or date marks on material prior to packaging
Method of manufacturing a package of the type formed from a single-layer or multilayer material sheet, where said package has an easy to open feature, where the sheet is shaped into the finished package having an inner side suitable to be in contact with the matter to be packaged and an outer side, comprising the following method steps: forming the film into a tube, by connecting the two side edges of the sheet longitudinally; where the connection creates a side flap (10) on the outside of the tube or where the tube is passed over a former having a projecting fin, whereby a side flap is formed on the outside of the tube; where cross seals (3, 4) are provided across the tube, thereby delimiting each package between two cross seals; that perforation lines (25) are established in said cross seals, for detaching/ separating two adjacent packages; that a perforation (7) of one material layer is established, parallel to and adjacent the side flap, extending from the perforation line towards or into the cross seal.
B65B 61/04 - Auxiliary devices, not otherwise provided for, for operating on sheets, blanks, webs, binding material, containers or packages for severing webs, or for separating joined packages
B65B 61/12 - Auxiliary devices, not otherwise provided for, for operating on sheets, blanks, webs, binding material, containers or packages for severing webs, or for separating joined packages by tearing along perforations or lines of weakness
B65D 75/44 - Individual packages cut from webs or tubes
B65B 9/20 - Enclosing successive articles or quantities of material, in preformed tubular webs, or in webs formed into tubes around filling nozzles, e.g. extruded tubular webs the webs being formed into tubes in situ around the filling nozzles
