发明名称 MULTILAYER CONTAINERS WITH IMPROVED STRESS CRACK PROPERTIES
摘要 <p>The present invention provides a container for use in the packaging of solid and liquid products which comprises a container whose bottom and side walls are fabricated from a multilayer polymeric material. It also provides a container which comprises a threaded container finish portion, a shoulder portion, a main body portion, and a bottom portion, in which at least the shoulder portion, the main body portion, and the bottom portion of the container are fabricated from a multilayer polymeric material. In the multilayer polymeric material, (a) the inner layer of the multilayer material is relatively thin and constitutes not more than about 40% of the thickness of the multilayer material and is a linear low density ethylene polymer having a density of less than about 0.94 gm/ml and having polymerized therein about 2 to 8 mol % of an alpha-monoolefin containing about 3 to 12 carbons and the balance ethylene; and (b) the principal layer of the multilayer material is relatively thick and constitutes at least about 60% of the thickness of said multilayer material and is a linear high density ethylene polymer having a density of at least about 0.94 gm/ml, a melt index of less than about 5.0 gm/10 min. and having polymerized therein at least about 98 mol % ethylene with any comonomer polymerized therein being an alpha-monoolefin containing about 3 to 12 carbon atoms.</p>
