  • Patent number: 8541077
    Abstract: The present invention relates to a multi-layer oriented shrink film comprising at least one skin layer comprising a polystyrene material and at least one core layer comprising a polyolefin layer. The films are preferably primarily oriented in either the machine or the cross direction. These films are ideally suited for use as a shrink label which can be applied either as a CD shrink sleeve or applied using a continuous roll process. The films ideally have an overall density of less than 1.0 g/cm3, to facilitate recycling efforts.

  • Publication number: 20110003524
    Abstract: A bicomponent fiber is obtainable from or comprises an ethylene/?-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481?1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven or non-woven fabrics, such as spunbond, melt blown and spun-laced fabrics or webs can be made from such fibers.

  • Patent number: 4780264
    Abstract: The draw resonance problems encountered when extrusion casting or extrusion coating linear low density polyethylene, LLDPE, are substantially alleviated by a polymer designed to have an I.sub.2 value in the range of about 0.1 to about 25, and an I.sub.10 /I.sub.2 ratio of not more than 8.3, preferably lower than 8.3. Line speeds approaching and even surpassing those attained with LDPE are made possible. This invention can even be used in conjunction with known prior methods for alleviating draw resonance problems with LLDPE and obtain the benefits of the combination. The I.sub.2 is measured in accordance with ASTM D-1238-190/2.16 and the I.sub.10 is measured in accordance with ASTM D-1238-190/10.

  • Patent number: 4486552
    Abstract: An ethylene polymer, especially a linear low density ethylene polymer, is mixed with certain antifog agents to provide a film-forming composition for making packaging films which resist fogging. The antifog agents are (1) an alkoxylated alkyl phenol along with a mixed mono-, di-, and/or triglyceride, (2) a polyoxyalkylene fatty acid ester, and (3) a combination of (2) and any part of (1). Optionally, a tackifier is added.
