A shrinkable-stretchable polymeric laminated structure is made up of a shrink-stretch film on the outside and a nonwoven on the inside, with or without an adhesive. Preferably the film, nonwoven and adhesive are made from the same polymer family, including copolymers, which renders the laminate 100% recyclable. The film, nonwoven, and adhesive are modified to provide different responses to heat in addition to controlled water vapor permeability. The structure allows for water vapor permeability in one direction (inside-to-outside) and not in the opposite direction to allow wrapped article to dry or to keep wrapped articles dry and prevent corrosion related damage.

A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part.

Polypropylene resin, polypropylene resin composition, and foam-injection-molded article

Номер: US20120264886A1
Автор: Ryoji Nakayama, Terumasa Abe, Tetsuo Okura
Принадлежит: Kaneka Corp

A polypropylene resin and a polypropylene resin composition are provided, which have excellent fluidity and foaming properties, and particularly in use for foam injection molding, allow molding with a narrow initial cavity clearance even if a large mold is used, and therefore can provide a thin, large-area foam-injection-molded article having good appearance. The invention relates to a polypropylene resin obtained by melt mixing a linear polypropylene resin, a radical polymerization initiator and a conjugated diene compound, wherein the polypropylene resin has a melt flow rate of more than 30 g/10 min and not more than 250 g/10 min as measured at 230° C. under a load of 2.16 kg; a melt tension at 200° C. of not less than 0.3 cN; and a loss tangent (tan δ) of not more than 6.0, the loss tangent being a ratio of loss modulus to storage modulus at an angular frequency of 1 rad/s in dynamic viscoelasticity measurement at 200° C., and also relates to a polypropylene resin composition for foam injection molding, containing the polypropylene resin.
