摘要： The present invention relates to a film structure comprising an outer layer, a core and an inner layer (or sealant layer). The outer layer comprises a polyolefinic material having a Vicat softening temperature of 85° C. or greater, and a total crystallinity in the range of 25 to 45%. The core comprises a linear low density polyethylene having a density of 0.925 g/cm3 or less, and a melt index of 4.0 g/10 min or less. The inner layer comprises linear low density polyethylene having a density of from 0.865 to 0.926 g/cm3 and a melt index of less than 4.0 g/10 minutes. The films of the present invention have less than 25% of polyethylenes having a density of 0.930 g/cm3 or greater. Further, the films of the present invention can be characterized by the substantial absence of polyamide, polyester, ethylene vinyl acetate, ionomers, polyvinyl chloride, and/or cyclic olefin polymers.

摘要： The present invention is an ethylene-based polymer comprising reacting a polyethylene resin with an alkoxy amine derivative corresponding to the formula: (R1)(R2)N—O—R3 where R1 and R2 are each independently of one another, hydrogen, C4-C42 alkyl or C4-C42 aryl or substituted hydrocarbon groups comprising O and/or N, and where R1 and R2 may form a ring structure together; and where R3 is hydrogen, a hydrocarbon or a substituted hydrocarbon group comprising O and/or N. Preferred groups for R3 include —C1-C19alkyl; —C6-C10aryl; —C2-C19akenyl; —O—C1-C19alkyl; —O—C6-C10aryl; —NH—C1-C19alkyl; —NH—C6-C10aryl; —N—(C1-C19alkyl)2. R3 most preferably contains an acyl group. The resulting resin has increased melt strength with higher ratio of elongational viscosities at 0.1 to 100 rad/s when compared to substantially similar polyethylene resins which have not been reacted with an alkoxy amine derivative.
