A recyclable packaging film includes an irradiated first film and a second film laminated to the first film. The first film includes a first polypropylene layer, a second polypropylene layer, and an ethylene vinyl alcohol (EVOH) layer between the first and second polypropylene layers.

Embodiments of the present disclosure are directed to a doped tin oxide. The doped tin oxide includes a tin oxide and at least one oxide of a doping element. The doping element includes at least one of vanadium and molybdenum. The doped tin oxide includes an amount of the tin oxide ranging from 90 mol % to 99 mol %, and an amount of the at least one oxide ranging from 1 mol % to 10 mol %.

Radiation pre-crosslinked polyolefin film and preparation method, and related encapsulation method and encapsulation assembly are provided. The radiation pre-crosslinked polyolefin film for encapsulation is prepared by preparing a film after mixing polyolefin raw materials together; using a radiation energy source to irradiate the film, wherein the radiation energy source directly stimulate a crosslinking reaction of the polyolefin raw materials; adjusting an irradiation dosage of the radiation energy source, such that a crosslinking degree of a pre-crosslinked portion of the film reaches about 3 % to about 95%; and adjusting the irradiation dosage of the radiation energy source, such that the pre-crosslinked portion of the film has a thickness of about 5% to about 100% by a total thickness of the film, wherein: that the pre-crosslinked portion has the thickness of about 100% by the total thickness of the film means the film is all pre-crosslinked.

Exemplary arrangements include articles and methods of producing plastic material objects. Such objects may be configured for use as an ocular implant, and intraocular lens, or a contact lens. Exemplary methods include ablating and polishing plastic material in a processing region of a plastic material object through operation of at least one laser such that some material in the region is de-crosslinked. Exemplary methods also include subsequently irradiating the processing region to at least partially re-cross-link the plastic material.

A physically crosslinked, closed cell continuous multilayer foam structure comprising at least one polypropylene/polyethylene coextruded foam layer is obtained. The multilayer foam structure is obtained by coextruding a multilayer structure comprising at least one foam composition layer, irradiating the coextruded structure with ionizing radiation, and continuously foaming the irradiated structure.

The present invention provides a three-dimensionally printed porous dosage composition and a method of producing the same.
