Bioflavonoid coated materials
Polymeric materials are described which have a bioflavonoid coating, the bioflavonoid content of the coating comprising at least naringin and neohesperidin. The use of such coated polymeric materials is also described as well as the process for making the coated polymeric materials.
Multilayer films
There is provided a multilayer film comprising a starch layer and at least one other layer. The multilayer film has excellent barrier properties. The starch layer comprises a modified starch having a degree of substitution less than 1.5. Suitable other layers include polyolefins. The multilayer film finds use in packaging, particularly in packaging foodstuffs.
Absorbent article with tackifier-free adhesive
A method of assembling an absorbent article having the steps of: a) providing a hot melt adhesive composition, wherein the adhesive has an amorphous polyolefin composition with more than 40% 1-butene and from about 10 wt. % to about 50 wt. % of a second amorphous polymer, and wherein the hot melt adhesive composition comprises less than 5% of a tackifier; b) providing a plurality of absorbent article components; and c) joining at least one of the absorbent article components to another of the absorbent article components using the adhesive so as to assemble the absorbent article.
STRESS-RESISTANT EXTRUDATES
Compositions and articles comprising a stress and crack resistant component comprising a thermoplastic component and an elongation component. In some examples, the invention is directed to a stress and crack resistant component comprising a thermoplastic component, an elongation modifier component and an elongation temperer; in preferred examples the thermoplastic component comprises a polyethylene terephthalate glycol-modified (PETG) copolyester, the elongation modifier component comprises a halogenated polyolefin having a heat of fusion of 1 J/g or less, and the elongation temperer comprises a poly(styrene acrylonitrile) (SAN).
In preferred examples the stress-resistant component is comprised as an coating component covering at least one surface of a substrate, such as one comprising a medium density fiberboard (MDF), a particle board, an oriented strand board, fiberglass, a natural wood, a composite wood product, and a synthetic substrate. The stress-resistant component is preferably, though not invariably, produced by extrusion. The invention is also directed to articles, such as extrusion profiles, comprising the stress-resistant component, and methods of making such articles.
PACKAGING SHEET FOR PACKAGING OF CHEESE, AND ASSOCIATED PACKAGING AND MANUFACTURING METHODS
Disclosed is a packaging sheet for packaging of cheese, in particular white moulded soft cheese. The packaging sheet comprises: an inner surface and an outer surface of the packaging sheet, said inner surface being configured for facing the cheese in a packaged use position of the packaging sheet; a paper layer with a first surface and a second surface; a coloured layer provided on a first surface of the paper layer, an outer surface of the coloured layer establishing said outer surface of the packaging sheet; and a polymer layer with a water vapour transmission rate of at least 300 g/m.sup.2/24 hours at 38° C. and 90% atmospheric humidity. The polymer layer being coated on the second surface of the paper layer with a first surface of the polymer layer facing the paper layer and a second surface of the polymer layer establishing said inner surface of the packaging sheet.
PROCESS FOR MANUFACTURING MULTI-LAYER SUBSTRATES COMPRISING SANDWICH LAYERS AND POLYETHYLENE
Methods for forming multi-layer substrates including top and bottom surface layers and a melt softened thermoplastic material layer between the exterior surface layers, where the thermoplastic material includes polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F.-350° F. The 3 (or more) layers are assembled, and heated, melt softening the thermoplastic material, causing bonding of the thermoplastic layer to the exterior surface layers. A cleaning composition may be loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel between the surface layers. Adhesion between the surface layers and the thermoplastic layer is provided by the thermoplastic material itself, which bonds to groups of fibers in the surface layers. The process does not require chemical adhesives, any processing water, drying, or the like, so as to be possible with low capital investment.
ABSORBENT ARTICLE WITH TACKIFIER-FREE ADHESIVE
Disposable absorbent articles assembled from a collection of components using an adhesive composition is disclosed. The adhesive composition comprises at least 90 wt. % of a copolymer, wherein the copolymer comprises from about 30 mole % to about 70 mole % of propene monomer units and from about 30 mole % to about 75 mole % of 1-butene monomer units. The adhesive composition is free of a heterophase copolymer.
Hot melt adhesive
An absorbent article having a liquid permeable interior layer, a liquid impervious exterior layer, an absorbent layer therebetween, and a hot melt adhesive composition having an amorphous polyolefin composition and a heterophase polyolefin copolymer composition with a first set of comonomer units and a second set of comonomer units, wherein the first set of comonomer units are propene.
Multi-layer substrates comprising sandwich layers and polyethylene
Multi-layer substrates comprising a top surface layer of pulp fibers, a bottom surface layer of pulp fibers, and a melted thermoplastic material layer between the pulp fiber layers, where the thermoplastic material comprises polyethylene or has a tan delta value of 0.2 to 0.4 within the temperature range of 100° F. to 350° F. The multi-layer substrate can include a cleaning composition loaded onto the multi-layer substrate, where a fluid pathway through the melted thermoplastic material allows the cleaning composition to travel from the top surface layer to the bottom surface layer. The multi-layer substrate may be void of chemical adhesives, where adhesion between the top surface layer and the thermoplastic layer, and between the bottom surface layer and the thermoplastic layer is instead provided by the thermoplastic material itself, which bonds to groups of fibers in the pulp fibers top and bottom surface layers that are in contact with the thermoplastic material as it melts.
HOT MELT ADHESIVE
An absorbent article having a liquid permeable interior layer, a liquid impervious exterior layer, an absorbent layer therebetween, and a hot melt adhesive composition having an amorphous polyolefin composition and a heterophase polyolefin copolymer composition with a first set of comonomer units and a second set of comonomer units, wherein the first set of comonomer units are propene.
