The TroFilms TroWOOD THERMAL is a partially acrylic coated, leather structured, biaxially oriented polypropylene foil; the backside is coated with EVA Hotmelt.
The EVA needs some time for optimal curing.
The time for curing depends on the used base material and should be tested before further processing. The thickness of the film is 38 µm (± 5 %); the foil can be used for materials of various kinds. The optimum processing temperature of the laminating roll is between 100 °C and 115 °C.
Properties of the film
- good tear resistance
- better separability
- better planarity
- gluability, printability and hot stamping applications possible in principle, but the structure may make conditions more difficult
Each master roll is tested and logged for gloss, surface energy, bonding and coating homogeneity before, during and after the coating process.
The reels have maximum winding and cutting quality.
At the beginning of each production process (change of varnish or film batch), a few meters get laminated and will be reviewed by our quality department.
Size and packaging
The films are available in widths from 160 mm to 1,270 mm. Each roll is wound on a 3" (76.2 mm) core and has at least 2,000 running meters on it. For each splice, we deliver 50 extra service meters. The coating is on the outside of the roll; EVA is on the inside.
