PACKAGING RESOURCE CENTER: The Latest in Bottles and Closures

 

 

Laser Marking Additive

An additive for laser marking can be safely used on caps and closures. The Micabs additive laser-marks closures to apply anticounterfeiting technology for the pharmaceutical packaging industry. Micabs’ high definition accommodates micromarkings and 2-D Data Matrix or bar codes. The additive can mark closures in complex recesses that are difficult to reach with conventional printing technology. Its high-speed laser technology can apply larger marks on closures, such as opening instructions on child-resistant packaging, without a reduction in line speed. Micabs’ additive in PP and HDPE formulations suits use with a fully automated laser marking system. This allows high-speed marking of text and logos with production speeds of up to 90,000 caps per hour. DSM Micabs, Evansville, IN; 800/333-4237; www.micabs.com.


Cap Liner System

A liner’s design seats it within a closure prior to capping and ensures that in­duction sealing bonds effectively. The Lockliner improves on traditional paperboard-backed foil liners, which are prone to curling when subjected to humid conditions during shipping or warehousing. This curling causes the liners to fall out prior to capping or wrinkle during capping, which affects efficiency and can produce downtime. Alternative tri-tab liners’ large, square tabs can distort eddy currents during induction sealing, which could compromise seal integrity. The Lockliner’s five protruding extensions prevent the liner from warping, bending, or falling out of place. The design minimizes eddy-current disruptions by protruding one-third of the distance of tri-tab extensions while being twice as wide, covering a larger area of the round perimeter.

Count Verification System

A high-speed tablet-scanning system scans, evaluates, and counts the product before it enters the bottle and ensures count accuracy. TruCount provides a fully integrated count verification and reject system that eliminates the need for operators. The unit features a stand-alone control module with 15-in. touch screen monitor. TruCount is mounted on casters for mobility. IMA Nova, Leominster, MA; 978/537-8534; www.imanova.com.


Blowmold Material Monitor

A noncontact device is designed to monitor the material distribution of monolayer PET containers after they are formed in a blowmold and provide detailed feedback for manual or automated process management. The PETWall Profiler system expands measurement capabilities beyond just a few critical locations on a bottle to a comprehensive profile of the bottle sidewall. The system monitors containers for deviations in material distribution, material shifts, process problems, and random distribution-related events on any part of the bottle. Its miniaturized head design can be configured with up to 32 measurement locations (spaced at ½-in. intervals), and can accommodate container sizes up to 16 in. tall. The PETWall Profiler monitors thickness distribution on bottles at blowmold speeds exceeding 100,000 bottles per hour. Agr International Inc., Butler, PA; 724/482-2163; www.agrintl.com.
