The material of the reflective film you usually ask refers to the material of the surface of the reflective film. The structure of the reflective film and the material of the reflective layer determine the reflective performance, while the surface material directly determines the weather resistance, the speed of fading, and that is, how long it can be used outdoors. The sealed capsule type glass bead reflective film generally consists of a surface layer, an air bag, a high refractive index glass bead (reflective prism), a bead aluminum plating layer, a hot melt adhesive layer, a support layer, a backing layer, and a release layer. Most advertising reflective films are glass bead embedded reflective films, which are composed of a surface layer+glass bead layer+adhesive backing+release paper structure.


Material classification and processing performance of advertising grade reflective film
The surface materials of advertising grade reflective film are usually PVC, PET, PC, and acrylic.
1. Generally speaking, the surface layer of the crystal color grid inkjet reflective film is made of PVC, because the PVC polymer material has strong ink absorption and can be directly used for inkjet printing. The PVC mesh clip fabric of the reflective inkjet fabric has tensile strength and strong tensile performance, and it can be used like ordinary mesh clip fabric.
There are two types of reflective film mesh cloth with crystal color grid spray painting and PVC self-adhesive type. The former does not contain back glue. If it is only used for spray painting, it can even be used without back glue and release paper.
2. The most common material for advertising grade reflective films is PET, because it has extremely strong flexibility, is not easy to tear, is easy to operate, and is easy to engrave. It can be screen printed with PET special ink. The common 3100 advertising reflective film on the market is made of PET.
3. The flexibility of the material acrylic is not as good as that of PET, but it has good weather resistance.
4. The same structure type can have different materials and colors on its surface. The 1920 flexible prismatic structural reflective film has PET, PC, and acrylic materials on its surface. Different materials and different processing properties correspond to different usage scenarios.
Advertising reflective film usually has no problems with photo and UV printing.
