Twist-off caps are made primarily from tinplate, which is a thin sheet of tin-coated steel.
In addition, they use “sealing elements” in the closure made from polyvinyl chloride (PVC) resins to ensure an airtight seal and maintain the freshness and quality of the packaged contents.
These lids are common in glass or plastic jars used for food packaging such as jams, mayonnaise, sauces, among other products.
