A co-extruded polyester film makes it easier to make stand-up food
pouches, the manufacturer claims.

Toray Plastics (America) said it is targeting the film at the food market, especially the snack and confections segments.

The demand for pouches is one of the big growth areas in the flexible packaging market. Demand for the packaging format is forecast to rise in the US by 6.6 per cent per year to reach $5.8 billion in 2009, Freedonia said in a study.

Toray Plastics said its Lumirror PA30 is a tack-sealable polyester that uses symmetrical transparent film technology.

The transparent film is modified on both sides for better adhesion properties both during laminating and printing.

This means either side of the film offers two different performance capabilities. Lumirror PA30 can also be used to tack seal to itself, or can be used to lap seal the inside surface of a lamination to the outside surface.

Tack sealing is done by making a lamination with another heat-sealable polyester film on the inside surface, and Lumirror PA30 is on the outside. The double lamination provides a permanent lamination and strong seal to help ensure brand integrity, Toray Plastics stated.

The film's good adhesion with printing inks supports water and solvent-based ink systems, as well as and aqueous coatings, including aqueous-based silicone release coatings.

Lumirror PA30 can be laminated, printed, or vacuum metalised. It handles well on high-speed equipment for improved processing and better production yield, and is easy to convert and print on, Toray Plastics claimed.

"In addition, it offers excellent thermal stability and superior mechanical properties, including high strength, dimensional stability and optical clarity,"​ the company stated.
