The Film paper tube can be used in BOPP, PET, TPU,EVA packaging film, winding film, aluminum plating film.
The Common Specification: inner diameter 76-254mm,wall thickness5-18.5mm.
The straightness of the paper tube is the most important factor for quality and efficiency. The straightness can reach 0.2mm/m, with high strength and rigidity.
For the thickness which less than 20μm,such as Lithium battery, isolation film, capacitor film, optical film, through polishing on the paper tube surface, the paper tube has a series of excellent surface characteristics such as seamless, smooth and high flat, which can reduce the pitting and wrinkle loss of the coil.
