Follow each mother reel from blown film through gravure print and solventless lamination to the finished stand-up pouch.

A stand-up pouch is built in layers. Film is blown, reverse printed, laminated to a cast polypropylene sealant web and slit to width before a bag machine sees it. Every step leaves a narrower reel.

Management software for plastic packaging makers follows the reel through extruder, press, laminator and slitter, and records artwork, structure and waste beside it. Describe the route your own reels take, from extruder to pouch machine, and each stage along it gets its own entry in the reel history.

A brand owner sends artwork, a pouch size and a film structure, such as printed PET laminated to a polyethylene sealant layer with a press-to-close zipper. You quote from micron, width and colours. Artwork goes through a proof, then anilox rolls, photopolymer plates or gravure cylinders are made, and the customer signs a colour match on press before the run starts.

Reels move through the plant in stages. The extruder makes the base film, and a dyne pen checks corona treatment so ink will anchor. The press prints it, the laminator bonds it to the sealant with a two-part adhesive, and the slitter cuts the web to width on 76 mm cores. Edge trim is wound and weighed. Pouch machines then form side-seal, three-side-seal or stand-up bags. Operators weigh each reel, count pouches into cartons and note start-up film at every machine.
