PEF paper cans are made of 100% renewable biomaterials. The product adopts an exclusive patented combination structure design, with the inner liner made of PEF material to solve the container barrier problem, and multiple components combined externally to provide pressure resistance. Each component is made of a single material, resulting in the shortest carbon footprint and lowest cost for the material to be reused after container consumption and recycling, truly achieving circular use. This product can widely replace aluminum alloy cans and tin cans. Meanwhile, the strong barrier properties of PEF material greatly enhance the shelf life of packaged food.
