Flex Banner PVC material
Flex Banner PVC material
We know that the main quality indicators of measuring flex banner (PVC material) are: tear resistance, UV resistance.permeability, ink absorption, light transmittance. whiteness.here are two ways to produce light box banner: laminating type (calendering method) and coated type
1. laminating production method is to produce two layer molding PYC film, by heating, under the pressure of the hot roller and themiddle of the light guide fiber together, cooling molding. The biggest characteristic of this kind of technology is good printingperformance. general ink absorption performance. but the cost is low. the maximum width of up fo 4 2 meters. and itsdisadvantages are also obvious, because the equipment and the production process 1s simple, anti stripping, poor resistance to Uyand in the high or low temperature condition has the phenomenon of thermal expansion and contraction.
2. Coated type production is the liquid PVC slury coated on the fabric of the positive and negative sides, and then through thedrying process to make it fully integrated into a whole.because the coated type product is up and down as a whole, the separationphenomenon can be eradicated, the anti UY performance can be improved, and the temperature 1s not affected. and the stitchingproperty is goodthe adsorption degree of the ink is greatly improved in the same kind of ink. the same natural environment, the use of coated banner resistance about 4 months longer then laminatedtype banner, mainly because the coated banner ink absorption is good. and after coating. it become whole with banner. Inkadsorption in coating. add a layer of protection. and the coaing itself has anti UV ability, and scour coating on rainwater haveobvious cushioning effect which will greatly extend the outdoor weathering timeFor the laminated type without coating, ink can only be adsorbed on the surface of the material, but can not penetrate the banner. Ifthe ink does not have the ability of anti ultraviolet. anti scratch and rain washing the outdoor weather resistance will become very short.
