Therefore, it is used for various goods such as yogurt containers, plastic cutlery, salad bowls, refrigerator lining, medical industry trays, and electrical insulation. Furthermore, HIPS sheets are relatively inexpensive and suit application requirements such as cheap cost, machinability, ease of thermoforming and printing, and are entirely recyclable.
