20080213563 | Polypropylene Film for Electron-Beam Hardening Applications - The invention relates to a Co-extruded, multilayer and biaxially-oriented polypropylene film, which comprises of at least one first sealable covering layer and at least one vacuolate layer, having a thickness of at least 5 μm, is further treated by laminating, pasting, printing, varnishing and/or coating; the result registered as follows: after drying or hardening during further treatments using electron-beam irradiation, the vacuolate layer has a thickness of at least 5 μm. Hot tack is not damaged by electron-beam processing. | 09-04-2008 |
20090011183 | Biaxially Oriented Polypropylene Film for Labels - The invention relates to a multi-layered biaxially oriented polypropylene film consisting of a base layer, a covering layer (I) which is applied to a first side of the film and contains at least between 80 and 100 wt. % of a propylene-ethylene copolymer, and another layer (II) which is applied to the opposing second side and contains between 40 and 100 wt. % of a propylene-ethylene copolymer. The propylene-ethylene copolymer of the two layers contains a maximum of 2.5 wt. % of ethylene and has a melting point between 145 and 160° C. The curl of the film can be controlled very well. | 01-08-2009 |
20090041965 | Label Film for a Blow Moulding Method - The invention relates to a biaxial oriented film with a microporous layer, comprising a propylene polymer and at least one β-nucleating agent the microporosity of which is generated by conversion of β-crystalline polypropylene on drawing the film and the use thereof for the labelling of containers in blow moulding. The Gurley value for the film is 10,000 to 300,000 Gurley. | 02-12-2009 |
20100255287 | LABEL FILM FOR DEEP DRAWING METHODS - The invention relates to the use of a bixailly oriented film having a porous layer, which contains propylene polymer and at least one β-nucleating agent and whose microporosity is generated by converting β-crystalline polypropylene during stretching of the film, for labeling containers during a drawing process. | 10-07-2010 |
20100326590 | LABEL FILM FOR DEEP-DRAW PROCESSES - The invention relates to the use of a multilayered, opaque, biaxially oriented polyolefin film of a vacuole-containing base layer and at least one inner cover layer comprising at least 30-95% by weight of a copolymer and/or terpolymer I having a seal initiation temperature I of 70-105° C. and 5 to 70% by weight of an incompatible polyethylene, each of the specifications in percent by weight being based on the weight of the inner cover layer and the inner cover layer having a seal initiation temperature II of 80 to 110° C. | 12-30-2010 |
20110268934 | LABEL FILM FOR DEEP-DRAWING PROCESSES - The invention relates to the use of a multilayer, biaxially oriented polyolefin film comprising at least five layers as the label in deep drawing, which film is constructed from the following layers

20130037983 | LABEL FILM FOR BLOW-MOULDING METHOD - The invention relates to a biaxial oriented film with a microporous layer, comprising a propylene polymer and at least one β-nucleating agent the microporosity of which is generated by conversion of β-crystalline polypropylene on drawing the film and the use thereof for the labelling of containers in blow moulding. The Gurley value for the film is 10,000 to 300,000 Gurley. | 02-14-2013 |
20130134625 | LABEL FILM FOR DEEP DRAWING METHODS - The invention relates to a method for producing a labeled container which uses deep drawing, in which a label which is cut to size is laid in a mold and a deep-drawable thick film is heated using heating elements to a temperature at which the polymer is thermoplastically deformable and subsequently the film is drawn into a mold using a molding tool or pneumatically, so that the film is tailored to the mold and a container is molded and simultaneously the inserted label is applied, wherein the label comprises a biaxially oriented film having a microporous layer, which has an open-pored, net-like structure, which was generated during the production of the film by converting β-crystalline polypropylene into alpha-crystalline polypropylene during the stretching, the microporous layer facing toward the container. | 05-30-2013 |
