Here's a more detailed breakdown:
* Plastic Film (PET): This is the base material. It's a strong, thin, and flexible plastic.
* Metallic Coating: A thin layer of metal (like aluminum) is often applied to give the glitter its reflective and sparkling properties.
* Colorant: Pigments or dyes are added to give the glitter its color.
* Other Coatings (Optional): Sometimes, other coatings are applied to improve the glitter's durability, UV resistance, or to create special effects.
Important Note: Traditional plastic glitter is a significant source of microplastic pollution, as it doesn't biodegrade and can persist in the environment for a very long time. Because of these pollution concerns, there's an increasing move towards biodegradable glitter alternatives. These are made from materials like cellulose (from plants), mica, or other natural materials. Always check the product label to determine the source of the glitter particles!
