Thermoforming
Thermoforming is a common manufacturing process where plastic sheets are heated until they become flexible, then shaped into specific forms using molds. It's widely used in making packaging products like food containers, blister packs for retail items, and disposable cups. Think of it like making shapes with warm plastic - similar to how a vacuum cleaner can make a plastic bag conform to its surface, but in an industrial setting. This process is popular in packaging because it's cost-effective for making large quantities of items and can create very precise, consistent products. Related terms you might see include vacuum forming, pressure forming, or plastic forming.
