TroPROTECT® MATT THERMAL
The TroFilms Protect® Matt ThermAL is an acrylic coated, biaxially oriented polypropylene foil; the backside is coated with EVA hot melt.
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 30 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
- matt surface
- good tear resistance
- suitable for hot stamping (test required)
- suitable for spot coatings with radical UV-curing systems (test required)
- glueable (test required / tests made on a folder gluing machine with different water-based glues brought a good result).
Properties of the coating
The coating has a declaration of conformity in accordance with Article 16 of EU Regulation 1935/2004. The low migration coating is suitable for the outside of food and other sensitive packaging. But we expressly point out that this is not a substitute for the declaration of conformity, needed to be issued by the manufacturer for his finished products.
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 1,440 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.
