Abstract
The invention discloses a pearl wool film roll core. The pearl wool film roll core comprises an inner roll core body made of hard materials. The inner roll core body is externally provided with a layer of outer roll core body made of pearl wool. According to the pearl wool film roll core, the layer of outer roll core body made of the pearl wool is arranged outside the inner roll core body, and therefore in the stress releasing process of a film, the soft pearl wool can deform properly to prevent the film from deforming, and the quality of the film can be effectively improved.
