<p>PURPOSE:To obtain a milk package which is excellent in automatic filling suitability for filling milk and heat-sealability, is recyclable, and is excellent in stability in a material cost, resistance against leakage and bag breakage by forming the container of a film having a low density polyethylene layer and a high density polyethylene layer under certain conditions with a specific thickness ratio. CONSTITUTION:A milk package is formed of a film having a low density polyethylene layer with a melt index of 0.1 to 10.0g/10min and density of at most 0.930g/cm<3> and a high density polyethylene layer with a melt index of 0.02 to 10.0g/10min and density of at least 0.940g/cm<3> wherein a ratio in thickness of the high density polyethylene layer to the low density polyethylene layer is 0.05 to 0.14. This package is light-weighted, its material cost is low, the package is excellent in automatic filling characteristics for filling milk, suitability for heat-sealing, resistance against leakage and resistance against bag breakage, further separation of paper at the time of recycling is not required, and the package is not bulky so that collection of the packages is easy, whereby further spread into a market is expected.</p> |
