Abstract: The disclosure is directed to a laminate structure including an encapsulant layer and a thermoplastic polymer layer. The encapsulant layer has a major surface, wherein the major surface of the encapsulant is treated to increase adhesion. The thermoplastic polymer layer has a melting point temperature or glass transition temperature greater than about 165° C., wherein the thermoplastic layer has a major surface that is treated to increase adhesion and is disposed on the treated major surface of the encapsulant layer. The disclosure is further directed to a method of forming the aforementioned laminate structure.

Abstract: A multilayer polymer film includes first and second polymer layers. The first polymer layer includes a first ultraviolet radiation absorber. The second polymer layer overlies the first polymer layer and includes a second ultraviolet radiation absorber. The first ultraviolet radiation absorber has a peak absorbtivity wavelength less than 300 nm and the second ultraviolet radiation absorber has a peak absorbtivity wavelength greater than 300 nm.

Abstract: A prefilled syringe and syringe assembly having a syringe and a tip cap are produced from materials that do not interfere with the substance contained in the syringe and enable long term storage. The tip cap is made from a blend of a cyclic olefin polymer or copolymer and a thermoplastic elastomer. The thermoplastic elastomer is blended with the cyclic olefin copolymer in an amount so that the normally stiff and hard cyclic olefin copolymer is flexible and resilient to effectively seal and couple to the tip of a prefilled syringe.

Abstract: Aspects of the invention are found in a multilayer film comprising a first polymer layer and a second polymer layer. The first polymer layer comprises a blend of a first fluoropolymer having a first average molecular weight and a second fluoropolymer having a second average molecular weight. The first average molecular weight is greater than the second average molecular weight.

Abstract: The disclosure is directed to a polymer film including a first layer and a second layer. The first layer includes a first fluoropolymer and has a melting point less than 135° C. The second layer overlies the first layer and includes a second fluoropolymer. The second layer has a melting point greater than 135° C.

Abstract: The disclosure is directed to a multilayer film including a first layer and a second layer. The first layer has a fluorinated polymer. The second layer has a melt strain-hardening component and forms no more than about 30% by volume of the multilayer film.

Abstract: A method of removing refractive defects formed in the matrix of a clear cyclic olefin component of a medical device during steam sterilization, wherein the clear polycyclicolefin component has been heated to a temperature of between 120° C. to 130° C. in the presence of steam. The method includes maintaining the polycyclicolefin component at a second temperature in a relatively drier atmosphere without reducing the temperature of the polycyclicolefin component to ambient temperature. Where the cyclic olefin component is a prefilled medical storage or delivery device, the second temperature is between 80° C. and less than 100° C. The method of this invention is particularly suitable to remove refractive defects formed in the matrix of a polycyclicolefin barrel of a prefilled syringe or cartridge following terminal sterilization.

Abstract: The present invention relates to thin, elastomeric films made from low crystallinity propylene copolymers having a crystallinity of less than about 30%. The elastomeric films of the present invention have improved strength in the cross machine direction. The films may be incorporated into laminate materials used in the outer coverings of diapers, training pants, incontinence products and the like.

Abstract: The present invention relates to a microporous film including a flexible polyolefin, more particularly, a propylene-based polymer with atactic polypropylene units. The present invention is also directed to a method of making the microporous film.

Abstract: A small amount of polypropylene material is added to polyethylene in order to produce a composition which substantially eliminates telescoping during storage of rolls of film. The anti-telescoping composition can contain other additives such as liquid additives and/or tackifiers (whether or not liquid). When such additives are used, the anti-telescoping composition of the invention allows the use of greater quantities of these additives in polyethylene than would otherwise be possible without causing telescoping.
