The pressurized vessel has been designed with a dispenser in the base that is blow-molded from polyethylene naphthalate (PEN), a strong polymer material capable of withstanding high internal pressure and maintaining integrity throughout a long shelf life.
This means that the design will hold up to extremes of temperature and pressure, problems that can lead to packaging mal-functioning if temperature or pressure exceeds certain limits.
"The new clear, pressurized vessel is capable of withstanding pressures in excess of 150 pounds per square inch and of maintaining package integrity at temperatures of 130 degrees Fahrenheit and higher," said Tom Coyle, director of new business development for Graham Packaging.
One of the particular problems the design tackles is that bought about from increased air travel, which, due to varying cabin pressures can often compromise personal care products packaged in pressurized containers.
The two companies believe that the product could have applications for a variety of personal care products, giving them reason to believe that the market reach for the dispensing system will be extensive.
"We anticipate expanding this business into new markets and products to meet new customer applications. Our partnership with SeaquistPerfect Dispensing has been an excellent experience in bringing joint value and innovation to the marketplace."
The design has also been recognized by the industry, having won the top prize in its category, 'Personal Care - Mass Distribution Leader' at the Sixth Annual Health & Beauty America International Packaging Design Awards.
"Creating a product line for pressurized vessels opens an entirely new category and is a logical extension for Graham Packaging," said Dave Andrulonis, vice president and general manager for personal care and specialty products.
Speaking about increasingly tough global packaging standards, SeaquistPerfect's Carleen Kreider explained how this has led to the development of this technology with Graham Packaging.
"Our concept was for a pressurized plastic vessel using a compressed gas (CO2) to dispense foam," Kredier said. "Because the usual plastic packaging materials were inappropriate, we needed a partner with a development team in place that would help us create an innovative, viable commercial product."
The first use of the container is for the Beyond Fresh Intimates brand of feminine products marketed by Lake Consumer Products and filled by Wisconsin Pharmacal. The product uses a non-flammable, non-hazardous, non-toxic propellant to dispense the product.
The product is expected to suit a range of other personal care products that require high pressure packaging, including foams and spray products used for shaving and hair care applications.
