Polykay

Polykay is a special type of plastic material. It's used to make products like water bottles, storage containers, and kitchen items. Polykay is strong and lightweight, so it's perfect for making things that need to be both lightweight and tough. Polykay is also resistant to heat, so it's safe to put hot liquids in containers made of this material. It's also dishwasher safe, so it's easy to clean.
