US PATENT No. 8,088,239
A method of manufacturing a laminate of polymeric tapes is provided. Polymeric tapes of the core-cladding type are used, in which the core material has a higher melting temperature than the cladding material. The method includes pretensioning the polymeric tapes, and positioning the polymeric tapes and consolidating the polymeric tapes to obtain the laminate. (Tm PE) resulting in a block of disentangled polyethylene, skiving a film or tape off the block of disentangled polyethylene.

US PATENT No. 20090139642
Method and device for manufacturing a moulding from plastic material. The invention relates to a method for manufacturing a moulding from a plastic material, preferably a fiber-reinforced plastic, which method comprises at least the steps of stacking at least one plastic layer to form a laminate; arranging the laminate between at least two membranes, at least one of which comprises heating elements; bringing the thus formed assembly to a first temperature by heating the heating elements of at least one membrane; forming the assembly by making use of a shaping tool brought to a second temperature. The invention also relates to a device for performing the method and a heatable membrane to be applied in the method.

US PATENT No. 8,168,022
Process for producing a laminate being built of at least two monolayers of polymeric tapes, the polymeric tapes having a tensile strength of at least 200 MPa, said process comprises the steps of forming a first monolayer of polymeric tapes by pre-tensioning the polymeric tapes and subsequently positioning the polymeric tapes under tension in a unidirectional, parallel manner.
US PATENT No. 2011/0183,103
Polymeric fibers coated with an olefin block copolymer containing resin and laminates comprising polymeric fibers in a resin of olefin block copolymers. The invention pertains to polymeric fibers coated with an olefin block copolymer resin and laminates comprising polymeric fibers embedded in a resin of olefin block copolymers. The tapes and the laminates are especially suitable for antiballistic applications as well as composite applications.

EU PATENT No. P 2493383 B1/ US 20130125309 A1
Patient table for X-ray or MRI device and method for the production thereof, made from polyolefin fibers or tapes. A patient table for diagnostic equipment includes at least one self-reinforced plastic. The present invention provides a possibility for supporting patients stably in one position for all common medical diagnostic methods equally during the examination period. Self-reinforced plastics, particularly self-reinforced poly-olefins and most especially self-reinforced polyethylene are used as material for producing a patient table. Ribbon-shaped, highly stretched monofilaments in particular have an array of properties which have very advantageous results for the production of patient tables for diagnostic equipment.

US PATENT No. 7,964,261
An antiballistic material comprising a stack comprising at least one layer of tapes exhibiting a strength between 50 cN/tex and 500 cN/tex and at least one layer of multifilament yarns having a strength above 60 cN/tex in one direction, the multifilament yarns comprising a plurality of individual filaments, wherein the at least one layer of tapes is present in its uni-directional with an angle of 0° form, the stack exhibits an adhesive content between 2% and 30% of the weight of the total stack leaving most of the individual filament.
US PATENT No. 2011/0028,671
Process for producing high strength polyethylene films or tapes comprising the steps of providing a quantity of disentangled polyethylene, applying a pressure of at least 20 bar to the quantity of disentangled polyethylene and a temperature between an α-relaxation temperature and a melting temperature of the disentangled polyethylene (Tm parallel manner).
