Produire des bouteilles PET à poignée intégrée
KHS agrémente l’InnoPET Blomax Série V, sa machine d’embouteillage par étirage-soufflage, de nouveaux moules actifs, capable ainsi de produire des bouteilles PET de grande contenance (jusqu’à 2,5 litres), dotées d’une poignée intégrée clipsée. Elles trouvent leurs applications dans le conditionnement de jus, d’huiles, de lait, et de produits d’entretien ménager ou encore de produits cosmétiques. Equipés de deux éléments mobiles supplémentaires, les «moules de soufflage actifs» se distinguent des traditionnels : ils peuvent être activés avec des pneumatiques pour former des points de montage, pour une prise stable sur le conteneur pendant le processus d’étirage-soufflage, la poignée étant fixée plus tard dans le process. Enfin, grâce au choix du matériau PET, le produit final offre un effet barrière satisfaisant et une bonne résistance pour le même poids qu’un matériau type PEHD ou PP.

 

PET containers with a hanging handle
KHS describes its new technology for producing PET containers with a hanging handle. Intended for bottlers, this new solution is integrated into the manufacturer's recently proven stretch blow-moulding machine: InnoPET Blomax V Series. By developing what KHS calls "active molds", it is now possible to produce large PET containers with a snap-on handle that can hold up to 2.5 litres. The main applications are the packaging of juices, oils, milk, household and personal care products. “Active blowing molds" differ from traditional blowing molds in that they are equipped with two additional moving parts. These can be activated with tires to form mounting points, and thus have a stable grip on the container during the stretch blow-moulding process, the handle being fixed later in the process. Finally, thanks to the choice of PET material, the finished product will have satisfactory barrier properties, and good strength for the same weight as a different material (such as HDPE or PP).

 

 

 

A new high-speed closure slitting machine. MMC Packaging, a Tekni-Plex business, highlighted its new high-speed closure slitting and band folding machine at K 2019, Dusseldorf, Germany. With a production up to 2,400 parts per minute, this new solution is ideal for plastic beverage closure manufacturers who perform a post-molding process of slitting and folding tamper-evident bands for closures ranging in size from 24 to 38mm. The system also features a six-camera vision inspection, to help meet quality objectives. The vision checks include closure integrity, closure contamination, bore seal gaging and cavity number recognition. The machine offers superior tracking capabilities and a patended spark inspection unit for pinhole detection at the injection point. A cap counting accumulation and boxing system are designed to avoid upstream process interruption.
