The core form is rolled material, with the core mostly made of paper or plastic. The specifications are uniform (commonly 3-inch and 6-inch cores), the roll is tight and not loose, and the outer layer is wrapped with a protective film to prevent dirt and scratches.
The width is flexible and adjustable (commonly 20mm-1000mm), and the length can be customized as needed (from hundreds of meters to thousands of meters). The film is flat, wrinkle-free, bubble-free, and scratch-free, and the edges are neatly cut without burrs, ensuring that the film does not jam or deviate when it is loaded onto the machine.
The thickness is uniform (commonly 15μm-100μm), and the firmness is suitable for different packaging scenarios (such as thin versions suitable for small snacks, and thick versions suitable for heavy packaging). There is no obvious stretching or deformation after unfolding.
