US based Toray Plastics has launched the new TreaTear LT series of linear-tear, polyproypylene sealant films, which can be used for developing non-retort pouches.
The new product is equipped with features such as low seal initiation temperature (SIT) and high heat-seal strength, which make it ideal to be used for lamination of the pouches.
Toray Plastics Torayfan division sales senior director Chris Voght said: "The demand for pouches, especially stand-up varieties, grows daily.
"A versatile, thin film with excellent sealant properties and precise tear is an important development for pouch manufacturing, usability, and consumer satisfaction."
These films are manufactured according to Toray’s proprietary design, which adds the advantage of a precise machine-direction linear tear.
According to Toray Plastics, this feature ensures easy usage, since it does not require laser scoring, perforations, or registration.
Coming in a thickness of around 30 microns, the new product is also better than conventionally used 60 or 70 micron sealant films, since it can deliver flexibility to the manufacturers for the overall lamination design.
Besides being compliant with FDA and CONEG standards, the film comes in clear, white and customised colour options, and is compatible with most zipper stocks.
The firm introduced a metallised Biaxially Oriented Polypropylene (BOPP) film, PWX5, in March, which enables usage as a high-performance, inner moisture and oxygen-barrier web in gas-flushed applications.
