Bottom sealing
SUNTEC S FILM™ securely heat-seals the films together at the back of the tray, preventing peeling due to moisture and peeling during transportation. Also, the bottom of the tray is finished flat, which improves work efficiency during packaging and display.
Comparison of heat seal and self-adhesive seal
SUNTEC S FILM™
The films are heat fused together at the bottom of the tray.
The films cannot be peeled off by moisture, thus protecting the contents.
Stretch film
Self-adhesive seal at the bottom of the tray.
Moisture may get around the bottom of the tray, causing the film to peel off.
The image below shows the results of a transportation test conducted over a distance of approximately 400 km, in which the contents were packaged with SUNTEC S FILM™ and PO stretch film.
