This disclosure relates to a laminate film that includes an oriented, polymeric film and a polyolefinic substrate. The oriented, polymeric film includes about 60.0 to about 95.0 wt % of a first polymer and about 5.0 to about 40.0 wt % of a propylene-based elastomer. The polyolefinic substrate is laminated to the first surface of the first surface layer.

Imageable multilayer films are provided which include at least a core layer comprising a pigment or other colorant, a clear sealant layer, and an image-side tie layer intermediate the core layer and the sealant layer, where the tie layer comprises a cavitating agent. The sealant layer may include a first polymer component having a heat of fusion of less than 75 J/g and a second polymer component. The multilayer film may have a seal strength greater than about 200 g/2.54 cm for a seal formed on a crimp sealer at a temperature of at least 93.3° C. The multilayer film may be biaxially oriented, an image may be effected on the film without the use of inks, and the film may be useful in packaging applications.
摘要:
Provided are polymeric films that include a polyolefin and at least one cavitating agent including a poly(alkylene terephthalate) of formula (I); wherein n, representing the number of methylene segments in the repeating unit, is 3 or an integer greater than or equal to 5; p, representing the degree of polymerization, is an integer greater than 1. The polymeric film may be an opaque polymeric film. A preferred cavitating agent is poly(trimethylene terephthalate). Also provided are methods for making such polymeric films.

Provided is a squeezable oriented polypropylene adhesive film that can be formed into a label comprising at least one core layer sandwiched between at least two skin layers, the layers comprising: a core layer comprising a polypropylene and within the range of from 20 wt % to 50 wt %, by weight of the materials in the core layer, of a propylene-α-olefin elastomer having within the range of from 5 wt % to 25 wt % α-olefin derived units, by weight of the elastomer; a printable skin layer comprising within the range of from 60 wt % to 100 wt %, by weight of the materials in the printable skin layer, or an α-olefin copolymer comprising at least 30 wt % ethylene; and an adhesive-accepting skin layer comprising within the range of from 60 wt % to 100 wt %, by weight of the materials in the adhesive-accepting skin layer, of a polypropylene.
摘要:
Novel coated substrates are disclosed wherein a substrate is coated with a coating composition that forms good hermetic seals at very low temperatures and exhibits good blocking and slip characteristics. Such coating composition is comprised of an aqueous dispersion of a substantially non-polar copolymer of ethylene and an alpha-olefin having less than 20 carbon atoms, and an additive selected from the group consisting of an anti-blocking and slip agent, a coalescent and wetting agent, and mixtures thereof.
摘要:
Thermoplastic films particularly suited for use in bags including at least a core layer comprising an ethylene copolymer, wherein the films are subjected to post-quench biaxial orientation are provided. Optionally, the films may have a first skin layer and/or a second skin layer located on each side of the core layer. Embodiments may have the desirable combination of improved puncture toughness and ultimate tensile strength, low manufacturing cost and desirable optical and tactile properties.
