The holographic film generally uses computer dot lithography, 3D true color holography, multiple and dynamic imaging techniques. The holographic image with rainbow dynamic and three-dimensional effect is transferred to PET, BOPP, PVC or coated substrate by molding, and then a certain laser laser effect is obtained by using composite, hot stamping, transfer and the like.
BOPP holographic laser film: high tensile strength, good barrier properties and high transparency. The thinnest 18mic.
Disadvantages: The elongation is lower than that of PP, and the heat sealing performance is poor. It is not easy to seal when used independently, and is generally combined with a film having good heat sealing properties such as PE.
PET holographic film: polyester, its main features: good weather resistance, can withstand high temperatures of 100-150 degrees, good hardness and smooth. The thinnest 12mic.
Disadvantages: Cannot be used on products with angles or corners.
PVC holographic film: Polyvinyl chloride, which is characterized by good flexibility and good weather resistance (SPVC). The factory only makes 4 wires, which is generally used for self-adhesive products.
Disadvantages: Not environmentally friendly, so many of the major international brands rarely use this material. This product is mainly used for anti-static protection, as well as wooden speaker surface.
PE holographic laser film: polyethylene, widely used in the protective film industry, its main features are: low price, soft, good extension, environmental protection and pollution-free, generally such products have passed the EU ROHS environmental pollution test.
Disadvantages: poor weather resistance, this material is not suitable for use at high temperatures, generally within 60 Celsius degrees.
