The ethylene-acrylate coating envelops the glass bottle like a protective skin providing better protection. Should the bottle break, the splintering hazards are reduced considerably. The maximum operating temperature for coated bottles is 80°C. To preserve the coating, do not clean at temperatures exceeding 60°C. Each bottle comes with a PP Screw Cap and LDPE Pouring Ring and is available as 250mL, 500mL, and 1000mL.
