  • Patent number: 5834077
    Abstract: A heat-shrinkable, biaxially-oriented, multilayer film has a first layer comprising an ethylene/alpha-olefin copolymer having a major DSC peak of less than 105.degree. C. The multilayer film has a free shrink, at 185.degree. F., of at least 80 percent, and all layers of the multilayer film are shrink-compatible with respect to one another. Preferably, the multilayer film has a second layer which is an oxygen barrier layer, and preferably both of the outer film layers are grease-resistant. Furthermore, the invention includes a bag comprising the multilayer film, as well as a packaged product having a package comprising the multilayer film.

  • Patent number: 4994458
    Abstract: A riboflavin granulate containing from 75 to 99.5 weight percent riboflavin is produced by:A. placing a desired quantity of riboflavin powder in the bowl of a rotary fluid bed granulator;B. fluidizing the powder with fluidizing air while rotating the rotor disc, whereby a fluidized cloud of riboflavin powder is produced; andC. spraying a binder solution into the fluidized cloud;so that at least 90 weight percent of the riboflavin powder combines to form granules.

  • Patent number: 4674271
    Abstract: The present invention pertains to a process and product thereof, and an apparatus, for converting a twisted, continuous filament, multifilament yarn into a staple-like yarn. The process is carried out by needling the yarn with a barbed needle in order to break yarn filaments. The broken yarn filaments protrude from the yarn after the needling process. The protruding filament ends give the resulting yarn the appearance of a spun yarn.
