A method (400) for producing packages (112) holding liquid food products from a web (102) of packaging material, wherein the web (102) comprises a number of blanks (300) placed after one another, wherein each blank corresponds to one package, the method comprising receiving (402) a reel (204) holding the web (102) of packaging material, capturing (402) reel data (210) from a tag (206) attached to the reel (204), transferring (404) the reel data (210) to a printing information database (218), receiving (406) printing information data (PID) (220) related to the reel data (210) from the printing information database (218), printing (408) décors on each of the blanks (300) of the web (102) of packaging material based on information provided via the PID (220) such that a décor provided web (246) is formed, transferring (410) the reel data (210) to a packaging machine information database (224), receiving (412) packaging machine information data (PMID) (226) related to the reel data (210) from the packaging machine information database (224), and forming (414) the packages (112) from the decor provided web (246) in a packaging machine (100) based on information provided via the PMID (226).

A winder includes a winding mechanism, a chamber, a vacuum pump, a conveying route and a product case. The winding mechanism winds a belt-shaped raw film around a winding core, the belt-shaped raw film being composed of a plurality of electrodes and a plurality of separating films. The chamber houses the winding mechanism. The vacuum pump sucks air into the chamber. The conveying route has a sealed outer space outside the chamber, an inner space of the chamber leading to the outer space in the conveyance route. The product case is disposed in the conveying route to house a plurality of winding products each formed by winding the raw film with use of the winding mechanism.

The present invention relates to a roll construction of laminated material that inhibits delamination of the polymer layer from a backer film upon unwinding of the roll construction. Particularly, aspects of the present invention are directed to a roll construction of laminated material prepared by a process that includes providing the laminated material having an ion-exchange resin layer, a release film, and a base layer, and feeding the laminated material to a roller to generate the roll of the laminated material. The laminated material is fed to the roller such that a first layer of the laminated material wound around the core includes the inner surface of the base layer of the first layer contacting an outer surface of the core.

The invention uses a new system which cuts and unlocks a wrapping material (PE film) for cotton in a continuous manner in cotton harvesting, and a new method in production of such film. The film consists of many segments that make many bales of cotton. The film is separated with perforation by laser or other methods. A double sided adhesive is used to glue the bale at the end of it, which is covered by a folded bridge. The bridge connects the both ends of the segments of the film. When perforated film is torn at a signal by the harvest machine, the bridge is unfolded as a leading edge for the next segment after a brief bridge linkage of both segments. The way of folding the bridge is key part of the invention, which accurately uncovers the end adhesive for the new bale and reduces the problem of tangling of the film at the time of separation.
