Q. What is the use of Uncoated polyvinyl chloride?

Uncoated polyvinyl chloride (PVC) and polyvinylidene chloride (PVDC): PVC and PVDC are closely related plastics that are a part of the group of polymers more commonly known as "vinyl", first developed in the 1930s. Its uses include "film" wrap for meats and water and cooking oil bottles. As a packaging material, PVC is most commonly formed into very thin plastic "film" (such as that used to wrap meat) and as thicker plastic "sheet," which is molded into some type of rigid container shaped like a "clam shell.". PVDC films are fat resistant and do not melt in contact with hot fats, making it suitable for 'freezer-to-oven' foods. It is also used as a coating for films and bottles to improve the barrier properties. Other common food packaging applications include clear blow-molded bottles and as "coatings" on other types of plastic packaging materials.
