Is there a difference between Poly glitter and Craft Glitter?
Poly (PET) glitter is more durable and lasts longer. Made from polyester fabric film (which has a plastic base within the fiber), Poly glitter can be used on all kinds of things, both indoors and outdoors. Poly glitter can be subjected to continuous UV light and very high temperatures (350°F), without losing its shine, melting or degrading over time. Poly glitter is generally speaking, more expensive due to its long lasting viability.
Craft glitter is primarily used for indoor crafting or providing short lasting sparkle (i.e. birthday party, wedding, etc). Craft glitter is made of cellophane film with a thin PVC base. Craft glitter cannot be exposed to UV and high temps and after about a year, craft glitter will lose it’s shine and become a “matted” version of the original creation. Craft glitter is typically less expensive but lower quality. If you are looking for long-lasting, durable glitter, craft glitter would not be recommended.
