PROBLEM TO BE SOLVED: To provide a low temperature with little odor, elution and migration of additives and deteriorated materials, and less thickness spots, which are suitably used in fields requiring clean packaging materials, containers, etc. for food, medicine, electronic materials, etc. A linear low density polyethylene film excellent in heat sealability and a method for producing the same. SOLUTION: A heat-sealable film comprising a linear low-density polyethylene composed of a copolymer of ethylene and an α-olefin having 3 to 12 carbon atoms, which does not contain an additive that migrates to an object to be contacted. A heat-sealable linear low-density polyethylene film characterized in that the thickness variation in the width direction of the film is within 10%. In addition, the heat-sealable linear low-density polyethylene film production method described above, wherein a T-slot die is used in T-die extrusion film formation. [Selection figure] None |
