Holographic Film
The laser film ( The seamless holographic film)is a high-tech product produced by combining laser holographic molding technology with optical, mechanical and vacuum coating technology on PET, BOPP and other packaging materials.
Our main products : 1.Holographic metallized film: It is a laser film formed by vacuum aluminum plating; it has a smooth aluminized layer, the aluminum layer has good adhesion, and the film has strong adhesion to the ink, and is suitable for various flat, concave and flexo printings. Widely used for flexible packaging, handbags, wrapping paper, gift boxes, composites, decoration, laser holographic anti-counterfeiting, laser imprinting laser and other fields.
2.Dielectric holographic film: refers to vacuum plating a layer of dielectric on the basis of holographic transparent film.
The dielectric layer can brighten the holographic pattern, resist acid and alkali and protect the pattern in the holographic film.Its holographic brightness is several times stronger than ordinary transparent film. It is mainly used in decorative materials; anti-counterfeiting labels and other fields.
3.Transparent holographic film: Transparent holographic film is mainly used in food, medicine, daily chemicals and other flexible packaging compound, paper products packaging, audio and video products and clothing transparent packaging bags, anti-counterfeiting labels and other fields.
