Apply stickpacks with two equal bag sides - the double-front stick. The longitudinal seal is arranged at the bag edge. Your standard vertical bag forming, filling and sealing machine will be capable of forming these bags with our forming shoulders for double-front sticks.
Aseptic packaging requires the application of hygienic designed forming shoulders. There must not be any inaccessible gap. Each part of the forming shoulder has to be accessible all over. We apply particular design patterns to achieve all of those requirements.
Forming shoulders could be applied to the production of plastic tubes if functional layers like an insulation layer should be wrapped around the plastic tube and bonded together. cross-section: round, oval or rectangular position of seal: typically lap of fin seal that are centred to the centre of the bag.
Forming shoulders are applied to the production of concrete tubes to protect the machine from contacting the concrete tube. Forming shoulders for a film width up to 1.500 mm have been realized yet.
Form of the seal: lap seal or fin seal centered to the center of the tube
Forming shoulders are used to produce longitudinal corrugated profiles. We realized a device that produced longitudinal corrugated cardboard. It turned out that the technology is applicable to different materials like plastic, woven and non-woven fabric or tin foils.
