Rollprint’s Allegro® T Sealant Offers Cost-effective, Clean-peel Solution for Pouches Which Use Uncoated Tyvek®
For Immediate Release
Addison, IL—(May 14, 2007)—Proprietary Allegro® T sealant, from Rollprint Packaging Products, Inc. offers a high performance, cost-effective way to seal to uncoated Tyvek® yet retain the features of a coated product. Allegro® T technology provides an ideal solution for pharmaceutical and medical device manufacturers looking to achieve fiber-free peels, consistent seal strength and minimize costs for chevron pouches.
Allegro® T, which relies on proprietary, polyethylene-based sealant chemistry, not only offers a wider operating window (approximately 35 degrees Fahrenheit), but also offers a consistent seal strength regardless of where in the temperature range the seal is activated. Because the strength of the seal is controlled by the Allegro® T chemistry, seal strength is independent of Tyvek® thickness.
The fiber-free peels provided by Allegro® T to Tyvek® are further enhanced by the same creamy white adhesive transfer that is achieved when pricier coated Tyvek® is used. In addition to the positive visual aesthetic, Allegro® T has excellent thermal and dimensional stability, and it is also suitable for ethylene oxide or gamma sterilization. As a result, users are able to maximize performance, while minimizing packaging costs. Allegro® T can be extrusion-coated, adhesive laminated or can be extruded into the film depending on the application and performance requirements.
Suitable applications include a broad variety of sterile medical and pharmaceutical products which use chevron pouches. Because the seal strength is so consistent over a broad range of temperature, pressure, and dwell settings, validating the process and statistically demonstrating a one pound/inch seal strength is easily achievable.
