Ionomeric, puncture resistant, thermoplastic bag

Abstract

A bag combination of: (A) a heat shrinkable film bag having a layer comprising: (a) 45-85 wt. % of a C copolymer (55-98° C. m.p.) of C or C ; (b) 5-35 wt. % of a second C &agr;-olefin copolymer (115-128° C. m.p.); and (c) 10-50 wt. % of a third polymer (60-110° C. m.p.) of an unmodified or anhydride-modified, EVA, EAA or copolymer of C and methacrylic acid or an alkyl acrylate; where a+b≧50 wt. % based on a+b+c; and the bag film has a total energy absorption≧0.70 Joule and a 90° C. shrink≧50%; and (B) a bag laminate which covers≧25% of the bag's surface; the laminate film comprising: 5-20 wt. % of (i) an ionomer; and 5-95 wt. % of (ii) a copolymer (55 to 95° C. m.p. and {overscore (M)} /{overscore (M)} of 1.5 to 3.5) of C and a C -C &agr;-olefin; 0 to 90 wt. % each of (iii) a copolymer of C and a C -C &agr;-olefin (100-125° C. m.p.); (iv) a copolymer (105 to 145° C. m.p.) of propylene and C or C ; and (v) a copolymer (125 to 135° C. m.p.) of C and C , C or C ; and (ii)+(iii)+(iv)+(v)≧80 wt. % based (i)+(ii)+(iii)+(iv)+(v); and the film and bag laminate has a total energy absorption of≧1.2 Joule.
