A multilayer laminate (100) comprises an oriented polyethylene film (102), a biaxially oriented film (104) adhered to the oriented polyethylene film (102), a barrier film (106) adhered to the biaxially oriented film (104), and a multilayer polyethylene (PE) film (108) adhered to the barrier film (106). The biaxially oriented film (104) comprises one or more components selected from biaxially oriented polyamide (BOPA), biaxially oriented polyethylene terephthalate (BOPET), and biaxially oriented polypropylene (BOPP).

A package comprises: a sterile barrier packaging film; self-sterilizing components comprising: a plurality of chlorite ions and water, wherein the self-sterilizing components are substantially free of an energy-activated catalyst and of an acid-releasing compound; a package interior formed by hermetically sealing the sterile barrier packaging film; and a headspace within the package interior comprising carbon dioxide present in an amount of greater than or equal to 5% by volume of the headspace. When the package is exposed to ultraviolet (UV) light having a wavelength of 254 nm, the chlorite ions react with the water to generate chlorine dioxide (ClO.sub.2), which is released into the headspace. In the absence of any UV light, there is not chlorine dioxide (ClO.sub.2) generation.

The invention relates to an adhesive dual-component composition based on polyurethane, comprising an —NCO component and an —OH component such that: the —NCO component is a composition comprising: A) at least one polyurethane prepolymer comprising at least two NCO terminal groups obtained by the polyaddition reaction of at least one dissymmetric diisocyanate monomer and at least one diol, and B) at least one triisocyanate selected from isocyanurates, biurets, diisocyanate and triol adducts, and the mixtures thereof; the —OH component is a composition comprising at least one polyol; at least one of the polyols or diols is selected from polyether polyols (or polyether diols); at least one of the polyols or diols is selected from polyester polyols (or polyester diols); and the weight ratio of the quantity of polyether polyol(s) to the quantity of polyester polyol(s), defined as r.sub.4, ranges from 0.6 to 2.2.

The present invention relates to an MDO heat-shrinkable film of a copolymer polyester having excellent thermal resistance. In particular, the present invention provides a copolymer polyester MDO (machine direction orientation) thermoresistant heat-shrinkable film that consists of a copolymer polyester resin including isosorbide and 1,4-cyclohexanedimethanol at an optimized content ratio as a diol component copolymerized with an acid component including terephthalic acid, and having a number average molecular weight of 18,000 g/mol or more, and can be used for labels, cap seals, direct packaging, etc. of various containers due to the high shrink initiation temperature.

Provided are a composite material and a preparation method therefor. The composite material comprises: a base layer; a first plant fibre fabric located on the upper surface of the base layer; optionally, a second plant fibre fabric located on the lower surface of the base layer; and resins present in each layer. The composite material has a decorative performance and an improved mechanical performance.

A polyester film laminated with other polymers to form a sheet. A laminated tube for liquid and paste products such as toothpastes, and the like can be manufactured from said sheet. The laminate comprises an outer polyethylene film, adhesive agent layers, a polyester film, and a composite polyethylene film comprising at least one co-extruded polyethylene layer sandwiched by at least one polyethylene film and an inner polyethylene film.

Provided herein are films comprising a core layer sandwiched between an outer layer and a scaling layer. The film has a seal initiation temperature at 5 N/15 mm between about 82° C. and about 88° C., a 1% secant modulus m MD between about 300 MPa and about 400 MPa, and plateau seal strength at between about 16 and about 17 N/15 mm. While the outer layer and core layers comprise polyethylene compositions, the sealing layer comprises a polyethylene blend.
