Abstract:
Die vorliegende Erfindung bezieht sich auf ein Verfahren zum Verschweißen von einem Polyolefin-Kunststoff mit einem Kunststoff aus einem Polymer mit mindestens einer aromatischen Einheit im Polymergrundgerüst unter Verwendung eines Primers, wobei der Primer mindestens ein Polymer, welches aus mindestens einem Monomer mit mindestens einer Doppelbindung aufgebaut wurde, enthält. Darüber hinaus betrifft die vorliegende Erfindung entsprechend verschweißte Produkte.
Abstract:
A die (12, 12', 112) for coextruding a plurality of fluid layers includes one or more distribution plates (32, 132), for forming relatively thick layers, and a microlayer assembly (34, 134) for forming a plurality of microlayers. The die (12, 12', 112) includes internal fluid passages (42, 62, 142, 162) and/or forming surfaces (172) to allow the microlayers to assemble into a microlayered fluid mass prior to merging with the relatively thick layers from the distribution plates (32, 132).
Abstract:
Methods for producing packages comprising an aesthetic design embossed in the package weld are disclosed. The method comprises providing a weldable packaging material and welding overlapped portions of that material to form a package, the welding being accomplished by a thermoforming device comprising forming plates etched or molded with the aesthetic design. Packages comprising an aesthetic design embossed in the package weld are also disclosed.
Abstract:
The present invention relates to blow molded multilayer hollow articles and a coextrusion blow molding process for the production of said multilayer hollow articles, made of thermoplastic polymers and characterized by a specific visual effect. More in particular, the present invention relates to multilayer hollow articles and a coextrusion blow molding process for the production of said multilayer hollow articles, wherein at least one layer is a continuous layer with a uniform degree of thickness and at least one layer is a discontinuous or a non-uniform continuous layer with varying degree of thickness, which results in a specific surface pattern and/or visual color effect.
Abstract:
Angular extrusion (AE) methods for creating monolithic polymers with high entanglement density, but small crystallite size, are disclosed. The methods involve consolidating granular polymer in an extrusion channel having at least one strain-imposing feature.
