Functional tie-layer formulations in biaxially oriented films containing HDPE
Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer consisting essentially of one or more ethylene-propylene copolymers. Further still, the multilayer film may include a second skin layer consisting essentially of one or more ethylene-propylene-butylene terpolymers. And yet further, the multilayer film may be oriented in at least one direction, and at least two layers of the multilayer film are coextruded.
1,2-PHENYLENE BRIDGED 1-INDENYL-2-INDENYL METALLOCENE COMPLEXES FOR OLEFIN POLYMERISATION
The invention relates to a metallocene complex according to formula (I), (I) wherein R.sub.1 and R.sub.2 are independently selected from H, an alkyl or an aryl group, wherein R.sub.3 is a C1-C10 alkyl group, wherein R′ is selected from H, an alkyl group, an aryl group and wherein different R′ substituents can be connected to form a ring structure and wherein B is a 1,2 phenylene bridging moiety, which can be optionally substituted, wherein Mt is selected from Ti, Zr and Hf, X is an anionic ligand, z is the number of X groups and equals the valence of Mt minus 2. The invention also relates to a catalyst comprising the reaction product of the metallocene complex and a cocatalyst. Further the invention relates to a (co)polymerisation process of olefinic monomers.

MULTILAYER FILM AND METHOD OF MAKING THE SAME
A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25° C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.
A MULTILAYER LIDDING FILM BASED ON POLYETHYLENE
A lidding film comprising oriented polyethylene bonded to non-oriented polyethylene is disclosed. The oriented polyethylene may comprise a plurality of layers and the non-oriented polyethylene may comprise a plurality of layers, wherein the oriented polyethylene is bonded to the non-oriented polyethylene by extrusion coating or by a laminating adhesive. The oriented polyethylene comprises machine direction oriented polyethylene (MDO PE) or biaxially oriented polyethylene (BOPE). The lidding film may comprise from 1 to 15 wt. % of a polymer other than polyethylene, preferably the lidding film comprises no more than 5 wt. % of a polymer other than polyethylene. Also disclosed is a sealed container comprising a lidding film according to the invention and a polymer tray wherein the lidding film is heat sealed to the top edge of the polymer tray via the non-oriented polyethylene, thereby enclosing a product within a recess defined by the polymer tray. Also disclosed is a method of producing a lidding film.
PACKAGING BODY
A packaging body configured with a packaging film, in which the outermost layer is a polyethylene-based resin layer and the polyethylene-based resin layer is uniaxially or biaxially stretched.
METHOD FOR PRODUCING DECORATIVE MATERIAL
Provided is a method for producing a decorative material, including: a preparation step of preparing sheet printed matters each including a substrate and a picture layer on one surface of the substrate and a roll of a transparent resin film having a first surface and a second surface opposing to each other, the first surface having a pattern of protrusions and depressions, the second surface having a pattern of protrusions and depressions that is shallower than the pattern of protrusions and depressions on the first surface; an application step of winding off the transparent resin film from the roll of a transparent resin film and applying an adhesive to the second surface of the transparent resin film; and a bonding step of bonding the second surface of the transparent resin film and the picture layer of each of the sheet printed matters with the adhesive.
POLYETHYLENE BASED LAMINATED FILM STRUCTURE WITH BARRIER PROPERTIES
Laminated film structure comprising at least one first film having a thin ceramic or metal coating, being laminated to a second film and whereby the laminated film structure is based on polyethylene only, i.e. polymers other than polyethylene are substantially absent and whereby the laminated film structure has good barrier properties
Process For Preventing Organoleptic Degradation In Flexibly-Packaged Sensitive Foods And Packaged Products Thereof
This invention relates to a process for reducing or eliminating organoleptic degradation in organoleptically sensitive foods packaged in flexible packaging, and packaged products thereof. This invention also relates to organoleptic flexible packaging made from polymeric films comprising oxidation-stable and non-migratory polysiloxane as slip additive. The oxidative-stability and non-migratory nature of the polysiloxane slip additive provides an organoleptic flexible packaging that is non-interactive with and inert to the organoleptically sensitive food packaged within, specifically: (1) coffee; (2) beer; (3) water; and (4) wine.
METHOD OF PRODUCING A LAMINATED METAL SHEET FOR PACKAGING APPLICATIONS AND LAMINATED METAL SHEET FOR PACKAGING APPLICATIONS PRODUCED THEREBY
