<p>PROBLEM TO BE SOLVED: To provide a packaging film which is good in packaging machine aptitude, clouding-proof properties, and optical properties and excellent in sealing properties and packaging finish by a high speed continuous packaging machine in shrink packaging which can obtain a packaging finish of a good appearance by heat shrinkage. SOLUTION: The packaging film is crosslinked specifically and made of a polyethylene resin and has specified heat-shrinking properties, heat-shrinking stress, cloudiness, glossiness, a dynamic friction coefficient, and hot tack seal strength. A specified amount of a fatty acid glycerin ester surfactant is distributed in a layer on the surface of the film.</p> |
