Press Release Summary:
Torayfan® TreaTear(TM) DR02 polypropylene sealant films suit pouches that require 100% ink coverage, while DR22 films are for applications requiring high clarity. Both provide directional tear for retort pouches and work as sealant layer in any type of pouch lamination. Laser scoring or perforations are not necessary, and films are available in clear and white in thicknesses of 30-100 microns. They offer high heat seal strength and tolerate manufacturing processes.
Original Press Release:
Toray Plastics (America), Inc., Launches the Treatear(TM) Family of Advanced Directional-Tear Sealant Films for Pouches
New Torayfan® TreaTear(TM) polypropylene directional-tear sealant films for retort applications commercialized
Laser scoring and perforations eliminated; sustainability benefits gained
North Kingstown, Rhode Island - Toray Plastics (America), Inc., the only United States manufacturer of precision-performance polyester and polypropylene films, introduces to converters and CPG's new Torayfan® TreaTear(TM) polypropylene sealant films that provide effortless precise directional tear for retort pouches. New TreaTear films, made with Toray's proprietary patent-pending film design, work as the sealant layer in any type of pouch lamination and do not require laser scoring or perforations to make a clean, exact straight tear wherever it is needed on a pouch. Toray's first commercialized TreaTear films for retort applications are new DR02 and DR22 films. TreaTear DR02 film is for pouches that require 100% ink coverage. TreaTear DR22 film is for applications that require high clarity, for example, for a window to view pouch contents, and high strength. Applications for the new sealant films include seafood, chicken, prepared entrees, rice, military MRE's (Meal Ready-to-Eat), and pet food pouches.
Available as thin as 30 microns (1.2 mil.) TreaTear films offer yield advantages over the traditional 60 or 70 micron sealant web films, as well as flexibility with overall lamination design. Laminations that use additional webs for directional tear, such as oriented nylon, may now find that web to be unnecessary. Additionally, these thin films offer important sustainability benefits. New TreaTear films are exceptionally strong, standing up to the rigors of manufacturing and offering the rigidity required for attractive, protective barrier pouches. TreaTear films' unique properties also offer high heat seal strength when tested pre-and post-retort. TreaTear DR02 and DR22 sealant films are available in clear and white in 30 - 100 microns.
"Combining precise straight directional tear with seal strength for retort applications is a significant development in the evolution of flexible packaging," says Matt Brown, Operations Manager, Toray Plastics (America), Inc. "Pouches made with TreaTear film bring value to the consumer by enhancing ease-of-use and reducing spillage. Converters benefit from improved pouch performance, greater production efficiencies, potentially better yields, and sustainability advantages. In the near future, we will make an announcement about directional-tear advancements for non-retort pouches. The increasing acceptance by the U.S. consumer of retort and non-retort pouches makes the market potential here extraordinary."
Converters can now forgo laser scoring and the registration requirements associated with it. A simple slit is all that is needed to establish a tear. Common "V" notches are unnecessary and loose "chads" from those notches are no longer a concern. In addition, TreaTear films are more rigid than common CPP films often used in retort applications and therefore may facilitate down-gauging of the overall lamination structure without sacrificing feel.
