Multi-layer laminated structures are disclosed. Such structures include a multi-layer polymeric film having a Layer A that includes at least one polymer and a polymeric sealant layer adjacent to Layer A. The sealant layer has a surface roughness, Ra&#x3e;5.0 and a Peak Count Value, Pc&#x3e;50.0. The multi-layer laminated structures also include a substrate in surface contact with the multi-layer polymeric film, typically opposite the sealant layer. Such structures have a top seal and/or side seal of the polymeric sealant layer to itself has a seal strength of &#x3e;5.00&#xd7;10grams/inch at 177&#xb0; C. The multi-layer films may be transparent, contain a cavitating agent, or are pigmented to form an opaque film. Also, the multi-layer film may be metallized or coated with a barrier coating.

Multi-layer films having improved sealing properties

A multilayer film structure including (a) a core layer having a first side and a second side, the core layer including at least one core polymer; (b) a first tie layer having a first side and a second side, the second side of the first tie layer on the first side of the core layer; (c) a second tie layer having a first side and a second side, the first side of the second tie layer on the second side of the core layer; (d) a sealant skin layer having a side on the first side of the first tie layer; and (e) a second skin layer having a side on the second side of the second tie layer, is provided.

Medium density polyethylene film layer and multilayer film comprising same

This disclosure relates to a film comprising a metal receiving layer, the first layer comprising a blend of a first polymer and 5-25 wt. % of a second polymer, the second polymer is a metallocene-catalyzed elastomeric ethylene-propylene copolymer having an ethylene content of less than or equal to 10 wt. %, the first polymer is different from the second polymer.

Film composition and method of making the same

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.

Laminate film and method of making the same

Disclosed herein is an improved, metallized polymer film and method for preparing the same. Such films comprise a) at least one treated polymeric skin layer comprising butylene, and b) a metal layer deposited onto at least one surface of this polymeric skin layer. The polymeric skin layer can comprise a propylene-butylene copolymer or an ethylene-propylene-butylene terpolymer, with this copolymer or terpolymer containing from about 4 wt % to about 12 wt % of butylene. The polymeric skin layer is preferably preconditioned by subjecting an outermost surface thereof to plasma treatment which facilitates the deposition thereon of a strongly adhering metal layer which is preferably aluminum. The resulting multi-layer films exhibit metal adhesion bond strength of at least about 100 grams/25 mm. These films will preferably also exhibit a Water Vapor Transmission Rate of from about 0.05 to about 0.2 g/m/24 hour, and an Oxygen Transmission Rate of from about 5.0 to about 20 cm/m/24 hour.

Metallized polymeric films

A heat sealable, multi-layer film structure for multi-color printing or lamination processes and method for making the same are provided. The multi-layer film structure may include a core layer comprising a thermoplastic polymer and essentially no migratory slip agents; a functional layer on a first side of the core layer, wherein the functional layer is a printable layer or a laminatable layer; and a heat sealable skin layer on a second side of the core layer, the heat sealable skin layer comprising a thermoplastic polymer and a slip system. The multi-layer film structure is prepared without any migratory slip additives. Without migratory slip additives, the multi-layer film structure exhibits excellent machinability on typical packaging equipment.

Multi-layer slip film for printing and lamination processes

Heat-sealable, multi-layer composite packaging structures that are suitable for packaging and having improved sealing properties and simplified construction as compared to prior art composite film constructions are disclosed. The inventive film structure includes a first substrate, such as paper, bonded such as by extrusion lamination, to a sealable, high-barrier film. This inventive 'paper-adhesive-polymer' lamination may replace prior art 'paper-adhesive-foil-adhesive' foil-based tandem laminations. An improved or comparable polymer film substrate may replace the &#x201c;foil-adhesive&#x201d; layer components of the popular incumbent prior art structure.

Sealable packaging structures and applications related thereto

An oriented multilayer film containing a core layer and a first skin layer, wherein the first skin layer includes a metallocene-catalyzed propylene homopolymer or copolymer, and the first skin layer is metallized. The film may also contain additional layers, such as a second skin layer for heat-sealing, and one or more tie layers. The film may be laminated to other films or non-films. The film exhibits excellent water vapor transmission rates (WVTR) and oxygen transmission rates (OTR).

Multilayer polymeric film

The present invention relates to a matte surface film comprising: a base layer comprising a polyolefin; and a matte surface layer comprising a blend of high molecular weight high density polyethylene (HMWHD PE) with at least one incompatible polyolefin. The incompatible polyolefin may be ethylene propylene (EP) copolymers, ethylene butylene propylene (EBP) terpolymers or polypropylene (PP) homopolymers, such as metallocene catalyzed isotactic polypropylene (m-iPP) or metallocene catalyzed syndiotatic polypropylene (m-sPP).
