An antifouling method for polysilicon includes using a tube-shaped resin sheet having an inner surface and an outer surface to prevent the fouling of polysilicon, in which the tube-shaped resin sheet or a resin sheet cut out of the tube-shaped resin sheet is held, with the inner surface being kept in an unexposed state, and the inner surface is exposed just before use and brought into contact with the polysilicon.

Antifouling method for polysilicon

A package in which a bag formed from a polyethylene-based resin film having a small thickness, more specifically a thickness of 300 &#x3bc;m or less is filled with crushed polysilicon (Si chunks) and damage to the bag by the Si chunks is effectively prevented. In a polysilicon package in which the bagformed from a polyethylene-based resin having an average thickness of 300 &#x3bc;m or less is filled with the Si chunks, the baghas a heat-sealed bonded partat the bottom and is filled with the Si chunksto ensure that the maximum expansion of the bagbecomes 5% or less when the bagis held in an upright state with the bottom as a ground contact surface.
