Editor’s Note: Caps and closures provide the all important finish to a packaging operation, and serve crucial functions in the supply chain. When they are designed and applied correctly, they preserve the integrity of the product, and can also add visual appeal and help identify product type on the store shelf. But when design or execution are poor, caps can become an Achilles heal, resulting in leakers, weak product protection in the cooler, and poor functionality on the kitchen table.
For many years, cap suppliers and the companies that used them have worked together to improve all functions and in particular, tamper evidence. For milk jugs tamper evidence has become even more important in the last two years as FDA inspectors have put a new emphasis on secure closures. Even the commodity milk cap product lines are now being revamped with products that provide truer closure. The resulting products not only provide more security but they also reduce loss from leakage.
H.S. Crocker Co. has developed several new non-foil lidding structures to seal various size containers and polymers. For years, customers have asked for a pre die-cut lid other than foil. Metal detection, microwaveable, tear- and puncture-resistance are just a few of the advantages associated with these new materials. The company also produces paper and poly labels with and without over laminates and adhesives in roll-to-roll and single cut, heat-seal blister packs, in-mold labels, shrink film and various specialty printed projects for a range of applications. Printing is done on 9-color Flexographic presses from 13” – 32” with front and back print capabilities. The company can also offer portion cups (thermoformed and injection molded) in a variety of sizes and designs.

The whistle closure does not require any modification of the capping line, but cannot be used on aseptic lines, unless after irradiation.
