Mizkan Americas Meets Hot Fill Needs With Amcor's Long Neck Powerflex™ PET Bottle

Mizkan Americas, Mt. Prospect, Ill., a leading condiment manufacturer, has started using 16oz long neck Powerflex™ polyethylene terephthalate (PET) hot fill bottles from Amcor Rigid Plastics, a leading producer of PET packaging, for its Buccaneer Blends barbecue sauces. Mizkan recently moved from ambient fill bottles to hot fill containers for the Buccaneer Blends line - a product acquired by Mizkan during the purchase of World Harbor Sauces & Marinades, Auburn, Maine, earlier this year.

"To ensure product quality, we decided to switch from the ambient fill to the hot fill process," said Dave Rotunno, Director of Marketing for Mizkan. "Amcor's Powerflex bottle handles the hot fill process and offered the best solution to meet our manufacturing needs." The long neck PET bottle is finding increased use as a hot fill option in this food category, according to Amcor. The rest of the former World Harbors' line of sauces and marinades are bottled in ambient fill PET containers.

Amcor's Powerflex bottle features a patented panel-less design which takes hot fill (185°F) bottle options to a new level. Amcor's structural design eliminates the panels, and unlike competitive containers, provides a large, completely smooth rib-less label area. Amcor used design and manufacturing techniques to create a patented bottle that absorbs vacuum via a specially designed base. A unique diaphragm within the base draws upward as the liquid cools. It has the geometric characteristics to enable the inverted cone-shaped diaphragm to deflect upward as the vacuum is created.

Unlike conventional hot fill PET alternatives, PowerFlex bottles are easier to label since they don't have sidewall vacuum panels. Packers don't have to worry about mislabeling, that is; missing the vertical bars in applying labels. Nor do they have to deal with the ripple effect that occurs when labeling over panels.

The stock Powerflex bottle has a 38-mm finish and features a screw-top closure and a tamper-evident, plastic heat-shrink neck band. The long neck bottles deliver significant performance and cost advantages including portability (no breakage), light weight, recyclability, and reduced transportation costs. Consumers are drawn to the attractive, lightweight, and unbreakable features of the PET bottle compared to traditional glass containers.

Hot water tank for ovens made from PPS

In collaboration with Ticona and K.D. Fedderson, the German kitchen appliance manufacturer Miele Inc. has developed a new oven function for its high-performance ovens range available under the trade name H5000: these new Miele ovens are equipped with a special hot water tank that automatically takes in the right amount of water and dispenses it as jets of steam into the oven cavity. This new function, namely “moisture plus” is said to provide improved results in baking and roasting. This newly-developed hot water tank that has to withstand high temperature of up to 220°C has been made from a 15% glass fiber reinforced poly(phenylene sulphide) material i.e. Fortron™ MT9115L0 DW from Ticona by using an extrusion blow molding process. This PPS grade has been chosen because it complies with the FDA requirement and with the European 2002/72/EC directive for food contact application. Furthermore it exhibits high dimensional stability and minimal water absorption even under high thermal stresses. As for the extrusion blow molding process, it allows to eliminate the need for the subsequent welding of component that is necessary with injection molding.
