CAPS & CLOSURES 36 PETplanet Insider Vol. 21 No. 12/20 www.petpla.net Technologies Tethered closure designs vary according to the individual applications and beverage container speci fi cations. PackSys Global has developed two new slitting technologies to create solutions matching the EU directive require- ments and considering consumers’ convenience. All technologies deliver solutions with all the traditional bene fi ts of slit TE Band closures plus tethering. smarTether This technology can be imple- mented without machine modi fi ca- tions into all machines in PackSys portfolio. A choice and combina- tion of multiple horizontal, together with several vertical knives, allows slitting with either a randomly positioned hinge or a lasso styled tether. Conversion of existing pro- duction machines allows quick and cost-effective product conversion. smarTether is applicable on all major PET bottle closure applications. smarTether purposely leaves a thin and controllable skin in the sepa- ration area (to not completely cut through the plastic closure side wall). This provides a high-performance tethered closure suitable for high speed capping processes. smarTether technology experTether experTether, like smarTether, is designed for multiple slitting lines on both the horizontal and vertical axes. The spindles are fully and accurately synchronised to the slit- ting knives, located at the outside of the rotating slitting turret. The syn- chronised tooling ensures unique accuracy on slit lines and is the only method able to create customised slitting pattern on plastic closures as known from standard TE band slitting. Regardless of the required speed, experTether can handle it. experTether CapCompass technology When it is important the closure stays in a consumer-friendly posi- tion after opening (e.g. carton bricks, gable top, etc.), CapCompass is the right solution. After opening, the closure will fl ip away to a non- disturbing position. Simultaneous spindle movements allow accurate positioning of the plastic closure before slitting process starts. Opti- mised machine kinematics, paired with sequential knife penetration, provide gentle closure handling and make it therefore also suitable for thin wall and light weight closures. CapCompass orientation technology can be used with both smarTether and experTether to achieve the cus- tomer’s desired tethering style. PackSys Global has applied for patents on a number of the newly developed technologies related to tethered solutions. CapCompass
