We all appreciate the beauty of Glitter Powder, but what are the raw materials used to make it? The main raw material for Glitter Powder is rainbow film.
Introduction to Rainbow Film
The rainbow film is a plastic composite film made by melting and extruding two or more different refractive index resins. The film is created by layering these resins up to 100 times, with each layer being a few hundred nanometers thick. When visible light passes through the interface between each layer, it produces a weak reflection and interference. If the film has more than 100 layers, the thickness of each layer is roughly the same and the wavelength of light reflected from each layer is also the same, resulting in superposition and positive interference. This creates a colorful rainbow effect.
Rainbow film is also known as colorful film, dazzling film, illusionary film, and laser rainbow film. It can be stretched using a biaxial stretching machine, and the resulting product is more uniform and stronger.
Rainbow film is available in thicknesses ranging from 16u to 36u, and the main color systems include red background green, blue background gold, and blue background violet.
Applications of Rainbow Film
Rainbow film has a wide range of applications, including:
- Glitter powder and gold and silver wire industries: Rainbow film can be laminated with PET film and then coated and printed to create a new colorful illusion effect. It can be processed into gold and silver wire or glitter powder and is mainly used in the cosmetic industry, clothing printing industry, and ribbon industry.
- Paper products industry: Rainbow film can be composite coated with paper or white cardboard and used alone for gift box packaging. It can also be deep-processed after being compounded with rainbow film for use in anti-counterfeit packaging, cosmetics packaging, or gift outer packaging.
- Food packaging industry: Rainbow film is mainly used in fruit candy twist packaging and decorative packaging for craft candies. Its rainbow film effect and transparent characteristics make the packaged candy and the rainbow film appear as one, creating an excellent visual effect.
- Plastic industry: Rainbow film can be compounded with a variety of rigid panels for furniture decoration, wall corners, or glass curtain wall decoration, adding color to architecture and homes.
- Fabric industry: Rainbow film can be compounded with a variety of fabrics to create a colorful and dazzling effect.
Advantages of Rainbow Film
Rainbow film has several advantages, including:
- High brightness: Rainbow film reflects light in multiple directions, creating a bright and colorful effect.
- Easy to process: Rainbow film can be easily compounded with a variety of materials and processed using conventional equipment.
- Durability: Rainbow film has good weather resistance and aging resistance.
- Environmental protection: Rainbow film is non-toxic and can be recycled.
Conclusion
In conclusion, the main raw material used to make Glitter Powder is rainbow film, a plastic composite film created by layering resins. Rainbow film has a wide range of applications and several advantages, including high brightness, ease of processing, durability, and environmental protection.
