<p>A packaging material for photosensitive materials comprising a combination of a linear very low density polyethylene resin and a high density polyethylene resin as the resin components. The linear very low density polyethylene resin improves flexibility, low temperature resistance, heat sealing properties and physical strength such as impact puncture strength and tear strength. The polyethylene resin exhibits anitblocking property. The packaging material of the invention is excellent in flexibility, low temperature resistance and impact puncture strength, and blocking does no occur. Since the dispersibility of carbon black is excellent, lump generation trouble and fish eye trouble are rare. Moreover, low temperature heat sealability is excellent.</p> |
