Frontlit
A frontlit is a polyester or polyvinyl chloride fabric ( PVC ) coated with UV, solvent or water-based inks for digital printing .
Areas of application
Frontlit is mostly used in printed form for a wide variety of forms of advertising indoors or outdoors, for example as advertising tarpaulins or large posters. The material is only slightly translucent. There are also completely opaque qualities. The opacity is created by an incorporated, opaque intermediate layer, often a thin aluminum foil. Frontlit is partially also flame retardant (B1 certification according to DIN 4102) available. The normal quality corresponds to the fire resistance class DIN 4102-B2. Due to the comparatively low production costs, Frontlit banners are often used as an advertising medium or as privacy screens. Frontlit is a windproof full tarpaulin, in strong winds the banners can tear and cause accidents. To prevent this, the wind load should be calculated in advance .
production method
Basically there are two different types: cast and laminated Frontlit. Frontlit is also available in a wide variety of grammages from approx. 300 g / m² up to approx. 900 g / m² (truck tarpaulin). As a rule, the material is used with a grammage between 450 and 550 g / m². When used indoors, you should make sure that the material is B1 fire protection certified .
The material can be welded thermally or by high frequency. This process is used to manufacture large tarpaulins that go beyond the production dimensions of approx. 5000 mm web width. Folding over and welding creates a stable hem that can be provided with eyelets.
