Shatter-resistant and lighter than glass, narrow-neck polyethylene terephthalate bottles for hot-filled beverages have enjoyed steady growth lately. But only now is a wide-mouth PET jar for hot-filled food being commercialized as Tree Top Inc.
The 48-mm Plasti-Twist® Plus closure from White Cap (Downers Grove, IL) offers tamper evidence through a patented drop-down band. The closure is available with the E-Z Torque liner, a non-PVC thermoplastic elastomer liner that is molded into the cap.
Plastipak Packaging (Plymouth, MI) has introduced a new TE neck finish on its range of injection stretch/blow-molded hot-fillable PET bottles. When the plastic closure is twisted off and the TE band breaks away from it, the dimensions of the bottle finish permit the band to drop down significantly lower (left) than on industry-standard bottles (right).
This is the story of the in-line capper that almost got away. When the Nutrilite Div. of Amway Corp. wanted to double the speed of its vitamin packaging line, management was leaning toward a rotary capper.
A two-layer lid for single-serve food, dairy or cosmetics products is available from Label Makers (Pleasant Prairie, WI). The bottom layer is designed to be heat-sealed to the container, which can be constructed of PS or PP.
Several unorthodoxies on the filling line make it possible for this soft, squeezable, straight-walled polypropylene container to resist paneling after hot-filling. Also new is a first-of-its-kind on-line shrink label application in a bottling plant.
