The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.

The invention relates to use of polylactide (PLA) as an extruded polymer coating on paper or board intended for the production of containers and packages, which are heated in a stove or microwave oven. According to the invention a polyfunctional cross-linking agent, such as trialkyl isocyanurate (TAIC), is blended with PLA, and the extruded coating layer is subjected to cross-linking electron beam (EB) radiation. PLA may be used as such or blended with another biodegradable polyester such as polybutylene succinate (PBS). EB radiation has been found to improve adhesion of the coating to the paper or board substrate, heat-scalability of the coating, and heat-resistance of the finished containers and packages.

Methods of marking plastic-based products and marked plastic-based products are provided. Some methods include irradiating the product to alter the functionalization of the plastic. In general, the present disclosure features methods of marking substrates, e.g., substrates including plastics, such as plastic-based products, such as polymer banknotes. Such plastics can be rigid or flexible, e.g., elastomeric. Such plastics can be thermoplastic or thermosets. In some cases, the products are marked by irradiating plastic-based materials, e.g., sheet materials, under conditions that alter characteristics of the irradiated plastic.

An antibiotic-eluting article for implantation into a mammalian subject, produced by an additive manufacturing process wherein a polymeric material is concurrently deposited with a selected antibiotic. The additive manufacturing process may be a selective laser sintering process or a selective laser melting process or a selective heat sintering process or an electron beam melting process. The antibiotic-eluting article may be temporary or permanent orthopedic skeletal component, an orthopedic articulating joint replacement component, and/or an external hard-shell casing for an implantable device. One or more bone-growth-promoting compositions may be concurrently deposited with the polymeric material. The implantable device may be a cardiac pacemaker, a spinal cord stimulator, a neurostimulation system, an intrathecal drug pump for delivery of medicants into the spinal fluid, and infusion pump for delivery of chemotherapeutics and/or anti-spasmodics, an insulin pump, an osmotic pump, and a heparin pump.

Three-dimensional polymeric article (100) having first (101) and second (102) opposed major surfaces, a base body (103) having a first dimension, a second dimension perpendicular to the first dimension, and a thickness, wherein the thickness is orthogonal to the first and second dimensions, wherein the base body (103) comprises a plurality of alternating, adjacent first (107) and second (108) polymeric regions along the first dimension, wherein the second dimensions of the first (107) and second (108) regions extend at least partially across the second dimensions, wherein the first regions (107) have a first crosslink density, wherein the second regions (108) have a second crosslink density, wherein the second crosslink density of the second regions (108) are less than the first crosslink density of the first regions (107), wherein the first and second regions extend perpendicularly in two directions from a central plane (115) in the base body (103) parallel to the first and second dimensions of the polymeric article (100), and wherein the second regions (108) extend in each of said two directions further than does the first regions (107). Embodiments of the three-dimensional polymeric article described herein are useful for providing a dual sided, textured wrapping film such that greater grip is realized both on an item wrapped by the film and the wrapped item itself.

Methods of making oxidation and wear resistant polymeric materials using peroxide cross-linking and high temperature melting process are disclosed. A multiple step procedure for enabling the manufacturing of such material without size limitations is also disclosed.

The invention provides a process for producing a modified molded article capable of providing a diaphragm that is less likely to generate particles. The process for producing a modified molded article includes: molding modified polytetrafluoroethylene containing a tetrafluoroethylene unit and a modifying monomer unit based on a modifying monomer copolymerizable with tetrafluoroethylene to provide a molded article; and irradiating the molded article with not lower than 30 kGy but lower than 70 kGy of radiation at 270 C. to 310 C. to provide a modified molded article.

The present invention relates to a curable composition comprising an ethylenically unsaturated compound and a specific photoinitiator having dual initiation mechanisms. The invention also relates to a process for the preparation of a cured product, in particular a 3D-printed article, with this composition and to the use of this composition for obtaining an ink, a coating, a sealant, an adhesive, a molded article or a 3D-printed article. The invention further pertains to the use of a specific phosphine oxide photoinitiator in a 3D printing composition or 3D printing process.

A multi-component synthetic closure and/or a rod-shaped intermediate product which incorporate printed indicia comprising ink that is invisible under normal lighting and/or temperature conditions and a continuous, in-line manufacturing process therefor are described. In the preferred embodiment of the present disclosure, the core member of the synthetic closure and/or the rod-shaped intermediate product can be formed by a continuous extrusion process which enables the core to be manufactured as an elongated, continuous length of material. As the continuous elongated length of extruded material forming the central core is advanced from the extruder towards an outer skin forming station, the central core passes through a printing station for forming any desired indicia among which can be a registration mark that can be invisible under normal lighting and/or temperature conditions on the outer surface of the central core prior to the application of the outer skin layer.

The present invention provides a decorative sheet that excels in moldability and a decorative resin-molded article that uses the decorative sheet and that excels in chemical resistance. In the decorative sheet, at least a substrate layer and a surface protection layer formed of an ionizing radiation curable resin composition are stacked. The surface protection layer includes blocked isocyanate.
