  • Patent number: 6552110
    Abstract: The subject invention pertains to thermoplastic marking compositions comprising a binder, which in turn comprise at least one homogeneous polymer. Accordingly, the subject invention provides a thermoplastic marking composition comprising: (a) from 10 to 80 weight percent of a binder, which in turn comprises: (i) from 1 to 99 weight percent of at least one homogeneous polymer; (ii) from 5 to 70 weight percent of at least one tackifier; (iii) from 0 to 10 weight percent of a polyethylene which has pendant acid functionality moieties of a non-functionalized wax; and (iv) from 0 to 20 weight percent of a plasticizer; and (b) from 20 to 90 weight percent of an inorganic filler. The subject formulations are usefully applied via spray, screed, and extrusion techniques.

  • Patent number: 5175049
    Abstract: A wrap-packaging film having differential cling is provided by a film laminate, said film laminate comprising at least two layers,at least one of which layers is an outer reverse layer comprising a linear very low density ethylene copolymer (LVLDPE) having a critical density of less than about 0.915 g/cc which contains a tackifier in an amount sufficient to impart thereto an effective level of cling properties,at least one of which layers comprises an obverse layer of an olefin polymer or copolymer, such as a linear low density ethylene copolymer (LLDPE) which has a critical density of not less than 0.916 g/cc which has little or no cling,and wherein the difference in density between the reverse layer and the obverse layer is at least about 0.004 g/cc,the said differential cling properties being manifested in the higher level of cling of the LVLDPE reverse layer as compared to that of the obverse layer.
