Abstract: The present invention provides polymer blends that can be used in a multilayer structure and to multilayer structures comprising one or more layers formed from such blends. In one aspect, a polymer blend comprises a copolymer comprising ethylene and at least one of methyl acrylate and ethyl acrylate having an acrylate content of 5 to 40 weight percent based on the weight of the copolymer and having a melt index (I2) of 1 to 60 g/10 minutes, wherein the total amount of ethylene methyl acrylate copolymer and ethylene ethyl acrylate copolymer comprises 45 to 99 weight percent of the blend based on the total weight of the blend, and a polyolefin having a density of 0.870 g/cm3 or more and having a melt index (I2) of 20 g/10 minutes or less, wherein the polyolefin comprises 1 to 55 weight percent of the blend based on the total weight of the blend.

Abstract: A bag-in-box assembly includes a box and a flexible container filled with a flowable material. The flexible container includes a front panel, a rear panel, and gusseted side panels adjoining the front panel and the rear panel along peripheral seals. Each peripheral seal having an arcuate body seal inner edge (ABSIE) and a tapered seal inner edge extending from each end of a body seal. The ABSIE has a radius of curvature from 1.0 mm to 300.0 mm. The bag-in-box assembly includes a top perimeter, a center perimeter, and a bottom perimeter as well as an aggregate contact length (ACL) at each perimeter. A top ACL is from 50% to 90% of the top perimeter, a center ACL is from 5% to 50% of the center perimeter, and a bottom ACL is from 50% to 90% of the bottom perimeter.

Abstract: A flexible container (10) is disclosed. The flexible container (10) includes four panels (18, 20, 22, 24), each panel comprising a flexible multilayer film. Each flexible multilayer film is composed of a polymeric material. The four panels form (i) a body, (ii) a neck, and (iii) a handle. The handle (12) has an upper handle portion (12a) and a pair of spaced-apart legs (13, 15). The legs extend from the upper handle portion to the body on opposing sides of the neck. The flexible container includes a fitment (70) sealed to the neck. The flexible container includes a dispensing pump (100) attached to the fitment. The flexible container can provide a metered dose from a dispensing pump and the dispensing pump can also function as a handle to hand-carry the flexible container.
