Polystyrene Film

Features of Polystyrene Film

Polystyrene resin is generally used in housewares or home electronics such as refrigerator, food packaging and styrene foam. Ohishi Sangyo manufactures the polystyrene film named as Styrophane® and Clearphane®.
In addition to the basic function of polystyrene film, Our technical knowledge has driven Styrophane® and Clearphane® to be better suited for conversion such as printing and molding. Moreover we have strength and capabilities to achieve shorter lead time, smaller lot size in production and many grades to support your business.

Features of Polystyrene Film

Product Lineup

Styrophane®

Styrophane® has better conversion for molding, strength of film itself and better performance in cutting. We can supply wide range of texture from hard type to soft or flexible type with matt finishing. Moreover, Styrophane® has been complied to Food Sanitation Act in Japan. We would like to develop and propose special application or grade to support our customer's requirement.

Styrophane
Styrophane

Styrophane® is used as laminate film(heat/extrusion lamination) to decorate and reinforce food trays,rice bowls and cup noodle containers made of polystyrene resin and which are used in supermarkets and convenience stores,etc.
Styrophane® used for food containers can be processed for different purpose and function. In general first process will be reverse printing on styrophane by gravure printing, second process will be vacuum molding for food trays or food packaging after heat lamination.

Styrophane
Utilizing the superior cutting properties and transparency of polystyrene film, we apply antistatic coating on Styrophane® to enhance processability for window envelops (as see photo on left hand side),which is why the Styrophane® is widely used as the material for window envelopes.
Styrophane
Styrophane® can contribute so much to recycling process in application such as labeling and taping in terms of same raw material of polystyrene in case that the component or packaging material is made of Polystyrene. Therefore, our Styrophane® label for box made of styrene foam has been utilized in recycling process of 'reduction' as well as the one for home electronics. We can supply the film with easy-peeling at back surface for our end user to separate the different material easily.
Styrophane
Styrophane® TRF has proven results as synthetic rubber packaging film for resin modifiers for long years. Compared to normal plastic film, Styrophane® has shown higher impact resistance and better heat seal.

Typical specification

ItemRange of specification
Thickness(μm) 20~100
Width(mm) 500~1060
Winding length(meter) 1000~4000

Please inquire with us for different requirement other than the above.
◎Compared to other plastics, the surface of polystyrene film also has shown better peformance in wettability.Therefore, we normally will not apply corona treatment on surface of film. We also offer single-side corona treatment if you required.
◎Styrophane® is oriented film with better balancing in extension, which has better processability in molding and better strength.

Clearphane®

Through our further development of production in Styrophane® , Clearphane® has enhanced basic performance with balancing extension in machine direction (MD) and transverse direction (TD) in our polystyrene film.
Clearphane® is enhanced in terms of performance in cutting, stiffness and processability in molding which will be able to contribute to improve the suitability for machine, glossy surface in packaging and less chance in trouble for molding in packaging.
