TL;DR: In this article, a sealant layer composition consisting of polyethylene homopolymer, polypropylene, polyvinyl acetate copolymer, and carboxyl modified polyethylenes, when sealed to another outer film layer comprising at least one member selected from the group consisting of ionomer, acid copolymers, and ethylene/acrylate copolym, has been discovered to provide a seal strength comparable to an ionomer to ionomer seal.
Abstract: Films containing a sealant layer composition comprising: (1) polyethylene homopolymer, and ethylene/alpha-olefin copolymer, ethylene vinyl acetate copolymer, and ethylene/acrylate copolymer; and (2) elastomer, plastomer, ionomer, and carboxyl-modified polyethylene; when sealed to another outer film layer comprising at least one member selected from the group consisting of ionomer, ethylene/acid copolymer, ethylene/vinyl acetate copolymer and ethylene/acrylate copolymer, have been discovered to provide a seal strength comparable to an ionomer to ionomer seal.

TL;DR: In this article, a self-adhering film material made from a blend of metallocene polymers was proposed for sealing and wrapping applications, which are useful for sealing applications.
Abstract: Compositions comprising a blend of a MPEP (metallocene catalyzed polyethylene plastomer) and a MPEE (metallocene catalyzed olefin copolymer elastomer); self-adhering film materials made from a blend of these metallocene polymers; and methods of making these self-adhering film materials which are useful for sealing and wrapping applications.

TL;DR: In this article, a sealant layer composition comprising polyethylene homopolymer, ethylene/α-olefin copolymer, polyylene vinyl acetate copolymers, and/or ethylene or acrylate copolymics was proposed.
Abstract: Films containing a sealant layer composition comprising: (1) polyethylene homopolymer, ethylene/α-olefin copolymer, ethylene vinyl acetate copolymer, and/or ethylene/acrylate copolymer; and (2) elastomer, plastomer, ionomer, and/or carboxyl-modified polyethylene; when sealed to another outer film layer comprising ionomer, ethylene/acid copolymer, ethylene/vinyl acetate copolymer and/or ethylene/acrylate copolymer provide a seal having enhanced seal strength.

TL;DR: A thermoplastic polymer composition incorporating at least 50 wt.% polypropylene, at least 20 wt% of an elastomer such as EP rubber and at least 4 wt%.% plastomer is particularly useful in producing large components such as bumpers and exterior trim fascia for automobiles as discussed by the authors.
Abstract: A thermoplastic polymer composition incorporating at least about 50 wt.% polypropylene, at least about 20 wt.% of an elastomer such as EP rubber and at least about 4 wt.% plastomer. The plastomer is preferably a single site catalyzed ethylene based copolymer having a density less than about .915 g/cm3. By adjusting the amount of the plastomer in the composition, considerable control is secured over post-mold shrinkage of components produced through injection molding operations utilizing the composition. The composition can be prepared as a reactor blend or a melt blend. The composition is particularly useful in producing large components such as bumpers and exterior trim fascia for automobiles.

TL;DR: A sheet with a fibrillar structure has a rough surface, close to the natural conjunctive structure, and is so formed of a bio-compatible polymer, and may be impregnated with a very small amt. of a medical elastomer or plastomer as mentioned in this paper.
