Polypropylene Film TORAYFAN*Packaging materials

Toray's Torayfan* BO is a polypropylene film produced by biaxial extension process, first commercialized in Japan by Toray. It is the lightest among all plastic films, and it excels in transparency, strength, and scent barrier properties. Torayfan* is widely used in industrial applications, capacitors, and as packaging material.

Features

Strength

Torayfan* film has a very high tensile strength in both longitudinal and lateraldirections due to the biaxial extension process used in its manufacturing. It is most suitable as a component material for packaging where strength is crucial.

Transparency

Torayfan* has excellent transparency and yet is scratch-resistant. It gives high gloss, thus produces excellent printed finish, and helps to enhance the presentation of the packaged contents.

Anti-moisture property

Its water vapor transmission rate is extremely low, and is hygroscopic. Thus it is suitable for use in packaging where water content retention needs to be assured.

Temperature range for use

This film maintains its full properties across a wide range of temperature, from -50 to +130°C. It allows sterilizing by boiling after food has been filled into the container, as well as deep freeze storage.

Food hygiene

For food applications, users are requested to select types in compliance with applicable regulations including Article 10, Clause 1, of the Food Hygiene Act, and FDA regulations. Contact Toray for recommended types.

Processability

Printing

Torayfan* is compatible with roto gravure ink and flexography ink for polypropylene. When selecting the ink, be sure to consider the surface to be printed (treated or non-treated side), further post-processing applied including lamination, and packaging methods.

Laminating

This film is compatible with dry lamination and extrusion lamination. Adhesives which can be used are: urethane base adhesive for dry lamination and urethane, imine, or titanate base adhesive for extrusion lamination. Be sure to consider the application when selecting the adhesive.

Coating

Heat sealable types such as M114 and R128 can be used for heat sealing with no further processing. Other types can be used for heat sealing when laminated with PE, EVA, CPP or other materials. Excessive sealing temperature can impair the appearance due to thermal shrinkage. Hence, users are requested to select the appropnate temperature setting. In addition, hot wire sealing and ultrasonic sealing can be made.
