Moreover, are acrylic plastic sheets flexible?
How flexible is acrylic? Acrylic is relatively flexible compared to glass – it does bend. Thin acrylic sheets will bend more easily than thicker acrylic sheets. If you over-flex acrylic it can crack or break.
Subsequently, can PVC be used for food packaging?
Polyvinyl chloride, known as PVC, is one of the world’s leading synthetic polymers. It has many uses, ranging from long-term construction applications, such as pipes used in the transportation of potable water, to short-term uses, such as food packaging.
Can Schedule 40 PVC be used for potable water?
