  • Publication number: 20140134370
    Abstract: The present disclosure relates to a multilayered film comprising: an outer polyethylene layer; a core layer comprising 40% to 49% (w/w) of polypropylene homopolymer, 51% to 55% (w/w) of LLDPE, and 0% to 5% (w/w) of at least one additive; and an inner polyethylene layer. The multilayered film of the present disclosure exhibits good mechanical strength with lower thickness. The present disclosure also relates to a laminate comprising: an outer printing layer; a middle barrier layer; and an inner sealant layer; wherein at least one of the outer printing layer or the inner sealant layer is made up of a multilayered film comprising: an outer polyethylene layer; a core layer comprising 40% to 49% (w/w) of polypropylene homopolymer, 51% to 55% (w/w) of LLDPE, and 0% to 5% (w/w) of at least one additive; and an inner polyethylene layer. The present disclosure further relates to a laminated tube.

  • Publication number: 20130136908
    Abstract: The present invention in provides a multilayer sheet comprising a poly vinyl alcohol (PVOH) layer only as an oxygen barrier layer. The multilayer sheet comprises an outer layer and an inner layer wherein the poly vinyl alcohol (PVOH) layer is sandwiched. The present invention also provides an environmental friendly method for manufacturing a multilayer sheet comprising preparing aqueous emulsion of the polyvinyl alcohol and applying over the outer sheet and drying the same at about 100-120° C. This multilayer sheet can be recycled very efficiently as the percentage of polyethylene is more than 90%.
