Self-corrugating laminates useful in the manufacture of thermoelectric devices are disclosed. The laminates include an upper and a lower shrinkable film layer and a non-shrinkable core with a thermoelectric pattern formed thereon bonded between said upper and lower shrinkable film along bond lines arranged parallel, substantially parallel, radially, or annularly. The bond lines that bond the upper shrinkable film layer to top surface of the nonshrinkable core are staggered relative to the bond lines that bond the lower shrinkable film layer to the bottom surface of the non-shrinkable core such that upon shrinkage of the shrinkable film layers, structural corrugations are formed in the non-shrinkable core. Thermoelectric modules or devices and methods for forming them from the self-corrugating laminates are also described.

Disclosed are hot-melt adhesives prepared from aromatic-aliphatic polyesters containing terephthalic acid in combination with adipic acid, glutaric acid, or a mixture thereof, as diacid components and a diol component containing 1,4-butanediol, 1,6-hexanediol, or a combination thereof. These adhesives set up rapidly within a well-defined temperature window. The hot-melt adhesives can be used in a variety of applications, but are especially suited as seaming adhesives for roll-applied labels. These adhesives have melting temperatures and crystallization properties that allow their application at temperatures cool enough to prevent curling and premature shrinkage of the shrink label during seaming, and yet produce strong label seams that can withstand the elevated temperatures of a shrink tunnel without sacrificing line speed. Also disclosed are labeled containers and a process for applying a roll-on, shrink label to a container using the hot-melt adhesives of the invention.

Disclosed are hot-melt adhesives prepared from polyesters containing 1,4-cyclohexane-dicarboxylic acid as a diacid component and a diol component containing at least two diols chosen from 1,4-cyclohexanedimethanol, triethylene glycol, and diethylene glycol. These adhesives set up rapidly within a well-defined temperature window. The hot-melt adhesives can be used in a variety of applications, but are especially suited as seaming adhesives for roll-applied labels. These adhesives have melting temperatures and crystallization properties that allow their application at temperatures cool enough to prevent curling and premature shrinkage of the shrink label during seaming, and yet produce strong label seams that can withstand the elevated temperatures of a shrink tunnel without sacrificing line speed. Also disclosed are labeled containers and a process for applying a roll-on, shrink label to a container using the hot-melt adhesives of the invention.

The present invention is a non-woven web or composite structure comprising (a) from about 50 to about 90 weight percent of a natural cellulose fiber; (b) from about 10 to about 50 weight percent of a binder fiber component; (c) from 0 to about 20 weight percent of a filler; and (d) from 0 to about 8 weight percent of a dye or pigment.

Composite structures

A high pressure laminate is made of several layers of paper, including from bottom to top core sheets, a decor sheet and an overlay sheet. The core sheets are either composed of cellulose fibers or composed of 30 to 90 weight percent cellulose acetate fibers and 70 to 10 weight percent cellulose fibers. The core sheets are respectively coated with either a lamination polymer or a plasticizer. The decor sheet is composed of a mixture and a conventional amount of paper making dye. The mixture comprises 30 to about 90 weight percent cellulose acetate fibers, 10 to 70 weight percent cellulose fibers and 0 to 20 weight percent fillers. The decor sheet is coated with a plasticizer. The overlay sheet is composed of cellulose fibers and is coated with a lamination polymer. Upon application of heat and pressure to the several layers a laminate is formed having thermoplastic properties, improved postformability and a significant reduction in the release of volatile organics during formation.

High pressure laminates made with paper containing cellulose acetate

A decorative paper sheet for use in preparing a decorative laminate is made up of a matrix containing from about 15 to about 60 weight percent of cellulose and from about 40 to about 85 weight percent of cellulose acetate. The sheet also contains a plasticizer for the cellulose acetate in an amount ranging from about 40 to about 90 weight percent based on the weight of the cellulose acetate in said matrix. A filler material may be present in the sheet in an amount ranging from about 1 to about 18 weight percent based on the weight of the matrix. A low pressure laminate may be made from sheet and a structural substrate therefor by application of heat and pressure. The plasticized cellulose acetate fuses and resolidifies to bond the sheet to the structural substrate.
