1. Product Introduction

PVDC coated film (also known as K-film) typically refers to a thin film made from biaxially oriented polypropylene (BOPP), biaxially oriented polyester (BOPET), biaxially oriented polyamide (BOPA), and other films as the base material, coated with a polyvinylidene chloride (PVDC) emulsion. This product possesses excellent barrier properties against oxygen and water vapor, good printability and processability, and also offers a certain level of UV protection. It is widely used in flexible plastic packaging for baked goods, puffed foods, mooncakes, biscuits, cheese, jams, potato chips, meat products, dairy products, health supplements, and the tobacco industry. The company also produces coating film with EVOH coating, which also has good oxygen resistance.
