Paper tube, plastic core, winding core

This is a paper tube that solves issues related to film winding, such as rolled wrinkles, rolled curls, and step marks!

The core of the Showa round tube provides solutions to issues related to film winding, such as winding wrinkles, winding tendencies, and step marks. The "G Core" and "M Core" have special surface treatments that enhance the surface hardness of the core and minimize surface waviness, addressing issues like winding wrinkles and tendencies during film winding. The "Clean Core," in addition to the features of the "G Core" and "M Core," minimizes dust generation from the core. It has a proven track record in clean rooms and is widely used as a core for films in pharmaceutical and food packaging. The "Plastic Core" is manufactured through injection molding and exhibits excellent roundness and straightness. It has minimal core wobble during winding, allowing for increased film winding speed, leading to improved work efficiency and cost reduction. The "Step Core" and "SS Core" have added cushioning on the surface and are processed with steps to match the film thickness. This reduces wrinkle transfer caused by film thickness near the core, allowing for the use of expensive film until the end and reducing service winding. *For more details, please refer to the PDF document or feel free to contact us.*
