Hot-Fill Bottles feature low propensity to denting.
November 6, 2003 - Reboundâ„¢ structural attributes are scalable, enabling bottle production ranging from small, single-serve sizes to larger, multi-serve containers. Three of six standard vacuum panels are eliminated, increasing flat-area by 100% to support label application. Reboundâ„¢ bottles feature flex points, which help absorb pressure. Top load compresses container, Reboundâ„¢ panel deflects outward, and after weight is removed, container rebounds to original shape.

New PET Hot-Fill Standards Set With Launch Of Amcor's Reboundâ„¢ Line
Manchester, MI - (October 27, 2003) -Amcor PET Packaging establishes new hot-fill standards for polyethylene terephthalate (PET) bottles with the introduction of its Reboundâ„¢ line.
Amcor's new line offers substantial improvements to aesthetic and functional issues that have challenged hot-fill bottle design - Reboundâ„¢ provides a significantly lower propensity to denting, increased label support area for less label crinkling,
improved top load performance and the option to reduce PET material usage by up to 20%. Further, Rebound'sâ„¢ structural attributes and design elements are scalable enabling bottle production ranging from small, single-serve sizes all the way up to larger, multi-serve containers.
As an industry leader in heat-set bottle performance and quality, Amcor has adopted Reboundâ„¢ as its standard hot-fill design for all new product designs and launches. Existing products can easily be converted to take advantage of most of the Reboundâ„¢ benefits.
Amcor's focus on leading the PET bottle technology challenge has resulted in bottles with 50% less vacuum retention than conventional, hot-fill PET versions. The decrease in vacuum retention means that filled containers are less prone to denting,
helping to insure that the bottles will retain their intended shape all the way through the distribution cycle.
"Our new Reboundâ„¢ technology is yet another example of an Amcor's initiative which addresses both customer and consumer needs. Listening to our customers needs and delivering on those requirements is a key component of our partnership philosophy," says Russ Hubbard, vice president of product development.
Reboundâ„¢ technology also increases the label "flat-area" by 100%. This is accomplished by eliminating the need for three of the standard six vacuum panels seen on hot-fill bottles today. Since Reboundâ„¢ panel technology absorbs considerably more
vacuum than standard panels, Amcor has been able to eliminate every other panel on a round container - each eliminated panel is replaced with a flat area to support label application.
Reboundâ„¢ technology enables molded bottle panels to become a major design element rather than an engineering requirement. Packagers can now depart from traditional rectangles and into other label panel shapes-such as triangles, freeform shapes, etc.-to create additional branding opportunities.
Additional resilience is also realized under top load pressure - providing virtually infinite top load performance as measured on conventional QC equipment. Far from conventional, Reboundâ„¢ is designed with "flex points" which help absorb pressure. The
top load compresses the container, the Reboundâ„¢ panel deflects outward and after the weight is removed, the container "rebounds" to its original shape.
Further, Rebound'sâ„¢ features and benefits have been achieved while lightweighting the bottle-approximately 20%-compared to traditional hot-fill containers. This is attributed to Amcor's state-of-the-art injection molding expertise as well as advanced container design and processing capabilities. The result is a lightweight container that performs with a high degree of consistency on the packaging line.
The introduction of Reboundâ„¢ follows on the heels of two other successfiil heat-set bottle design programs within the past year. Single-serve, hot-fill designs were debuted under the "panel-less" banner and multiserve offerings were unveiled under the Ultimate brand.
Amcor PET Packaging is the leading manufacturer of PET (polyethylene terephthalate) plastic packaging for the global food and beverage industries, operating 48 plants in 18 countries. Its parent company, Amcor Ltd., offers a broad range of packaging solutions and ranks as one of the top five global packaging companies. Amcor's sales for the 2003 fiscal year that ended June 30, 2003, were US $7 billion.
