Plastic Technologies Inc. believes its new breakthrough grip-handle technology for containers can help consumer-goods companies reduce packaging weight by as much as 25 percent and explore new design aesthetics, particularly where high clarity is desired.
The new Deep Grip technology, unveiled at Pack Expo in Chicago, was developed jointly with Procter & Gamble in Cincinnati over the past year. It creates a grip deep enough for the average-sized hand to close around it completely and still not have the fingers of the person holding the bottle touch the container wall.
It is a new PET bottle that provides better market-shelf impact for the brand owner, said Ron Puvak, PTI director of business development and marketing, in a Nov. 1 interview at Pack Expo. Our objective was to create a more consumer-friendly package. It has a great grip-and-pour feature compared to mixed-materials packages.
The company just introduced samples of a number of containers.
Holland, Ohio-based PTI said the process used to make the Deep Grip bottles injection stretch blow molding offers several benefits compared to the extrusion blow molding process typically used to produce handled bottles.
Among the benefits from the injection stretch process, according to PTI, are potential weight reductions of 20-25 percent, higher output of 1,200 bottles per cavity per hour, a smaller equipment footprint and better drop and creep resistance.
Deep Grip technology is an ideal option for brand owners looking to drive weight and cost out of their containers, improve their environmental profile and create ways to differentiate their product, added Vincent Le Guen, managing director of PTI-Europe in Yverdon-les-Bains, Switzerland.
PTI-Europe will initially market Deep Grip containers in partnership with Sidel Group in Le Havre, France one of three industry divisions of privately owned, Pully, Switzerland-based Tetra Laval International SA.
Initial target uses for Deep Grip containers include detergents, household cleaners, milk, edible oils, motor oils and non-carbonated beverages such as juices, ready-to-drink teas and water.
We worked very closely on this with Procter & Gamble, said Puvak. They are very attuned to the consumers and wanted to develop an easier way for consumers to grip and pour liquids out of containers.
The molding process creates a handle that provides a grip depth of more than 1 inch on either side, as well as an extremely thin grip web thickness of less than 0.012 inch, with the grip web located where the hole would be in traditional handled bottles.
The bottles and their built-in handles are made from the same raw material, on Sidel equipment in a two-step process. The bottles are made via conventional stretch blow molding, and then a built-in secondary process in the same machine forms the handle. In addition, injection stretch blow molding allows the container to be blown and conveyed in-line to the filling operation, eliminating a manufacturing step.
Critically, the technology provides flexibility to the brand owner on handle location, shape and diameter, and can be used on containers as large as 1.5 gallons and bottles with diameters of 8.66 inches, the firm said.
