A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

A linerless thermal label web includes layers in the following order: a release layer, a thermal paper comprising a heat sensitive part, and an adhesive layer, wherein the adhesive layer includes an adhesive deadening varnish at longitudinal edge areas of the linerless thermal web so as to reduce the tackiness of the adhesive layer in the longitudinal edge areas. A thermal label can be produced from the label web and the label web can be used for variable information printing applications.

There is provided a vinyl alcohol-based polymer having an ethylenic double bond with a saponification degree of 70 mol % or more, wherein the vinyl alcohol-based polymer is water-soluble; a molar ratio of the ethylenic double bond to the total of vinyl alcohol units and vinyl acetate units is 0.05/100 to 2/100; and a limiting viscosity [η] and a weight-average molecular weight Mw of a vinyl ester-based polymer which is produced by esterifying the vinyl alcohol-based polymer satisfy the following formulas (1) and (2).

4.7≦log Mw 6.3   (1)

0.60<(log [η]+3.75)/log Mw<0.69   (2)

A multilayer laminate comprising in order, a polymeric film layer capable of withstanding a temperature of at least 200 C for at least 10 min, an adhesive layer having an areal weight of from 2 to 40 gsm capable of activation at a temperature of from 75 to 200 degrees C. and an inorganic refractory layer wherein the refractory layer comprises platelets in an amount at least 85% by weight with a dry areal weight of 15 to 50 gsm and has a residual moisture content of no greater than 10 percent by weight.

A wall covering comprising a planar substrate having a front and a back facing opposite the front and an adhesive layer that covers the back of the substrate. The adhesive layer includes a separate polymer layer, formed by a polyvinyl alcohol polymer. Wall covering for example in the form of a pre-pasted paper is readily reactivated when wet, and exhibits no blocking, while having properties of sliding, adhesion, and stripability.

Absorbent articles, such as diapers or sanitary napkins, comprising a hydrophilic hot melt adhesive with water wetting properties. The hydrophilic hot melt adhesive comprises an ethylene copolymer selected from the group consisting of ethylene vinyl acetate, ethylene n-butyl acrylate, ethylene octene, ethylene propylene, ethylene butene propylene, and mixtures thereof and a nonionic, fatty alcohol ethoxylate surfactant. The hot melt adhesive is particularly suitable for bonding a nonwoven to another component of the article.

Compositions comprising complexes of 1-methylcyclopropene and α-cyclodextrin, and articles including the composition, are provided. Methods for using the compositions and articles in delaying the maturation of fruits, vegetables, and plants are also provided.

An adhesive formulation such as a hot melt adhesive or a pressure sensitive adhesive is provided comprising 5 to 98% (by weight) biodegradable substantially non-crystalline mcl-PHA. The mcl-PHA may be cured with a peroxide curing agent. The adhesive formulation may include an additional biodegradable polymer, or a non-biodegradable thermoplastic elastomer. Hot melt adhesives comprising significant amounts of biodegradable mcl-PHA, waxes, and tackifiers are also provided.

According to an example aspect of the present invention, there is provided a method of joining objects of hydrophilic polymeric biomaterials. In the method, an ionic liquid is applied onto the surfaces of the objects; the surfaces are pressed together; and the ionic liquid is removed. The method produces a product that can consist to 100% of biomaterial, with no synthetic polymer or chemicals remaining in the product.

A sealant layer assembly which allows a sealant layer to be applied on a tire outside of tire production plants. The assembly comprises a sealant layer to be applied on the surface of an inner liner layer facing the inner cavity of a tire, a net layer arranged on a first surface of the sealant layer, and at least one non-stick protective layer arranged either on a second surface of the sealant layer opposite the first surface or on the net layer.
