The present invention is directed to synthetic attachment discs made from adhesive nanofibers and/or microfibers that are capable of attaching long fibers to a wide variety of surfaces, and related methods for forming and using them. The synthetic attachment discs of the present invention use very little material relative to prior art systems, while producing a very strong attachment force. Experimental and theoretical evidence are provided to confirm the advantages of thousands of micron-size ‘staple-pins’ and their low peeling angles to enhance the adhesive forces required to peel the synthetic attachment discs. The present invention provides a unique strategy for designing new adhesives that use very little material for various biomedical and material science applications.

The present disclosure is concerned with chub packaging webs with improved puncture resistance suitable for use in chub packaging. The webs have a double waii partially laminated structure. The structure is conveniently formed by adhesively laminating two component films in a face to face configuration using a pattern of adhesive which leaves a substantial portion of the two facing surfaces unlaminated. Preferably, each of the component films comprise at least one layer of nylon and has a moisture content of greater than 1% by weight such that the double wall partially laminated web has a total energy impact absorption value of greater 0.59 foot-pound at −20° C. measured in accordance with ASTM D-7192 test method.

A method of manufacturing a packaging sheet, the method being capable of not only greatly improving a heat insulation property of the packaging sheet, but also minimizing the volume of cells of the packaging sheet without opening the cells by cutting or needle-punching the cells, thereby facilitating storage and transportation of the packaging sheets while significantly reducing logistics costs.

A compostable laminate for food wrap and method for making same. The wrap can include a first layer of paper material, a second layer of paper material, and a series of coatings between the paper materials. The coatings include a first flood coating having water and/or barrier properties, a second flood coating having water and/or oil barrier properties, and a third coating that only partially covers the second flood coating. None of the first, second and third coatings comprise a thermoplastic or polyolefin, and are made substantially from one or more biodegradable and/or compostable materials.

The present invention provides a wood-based composite panel that is not susceptible to top surface edge swell, and methods of making the panel.

An article comprises a substrate, a first functional polymeric phase change material, and a plurality of containment structures that contain the first functional polymeric phase change material. The article may further comprise a second phase change material chemically bound to at least one of the plurality of containment structures or the substrate. In certain embodiments, the article further comprises a second phase change material and a binder that contains at least one of the first polymeric phase change material and the second phase change material. The containment structure may be a microcapsule or a particulate confinement material

A multilayer nonwoven structure is described where the nonwoven structure comprises at least two spun bond layers and at least one easily meltable layer. The easily meltable layer is located between the at least two spunbond layers. The easily meltable layer is comprised of a polymer having a melting point at least 20° C. less than the melting point of the polymer which comprises the surface of the fibers which comprise the spun bond layer, or is made from a polymer which is readily absorbs some form of radiation. Under bonding conditions, the fibers which make up the easily meltable layer can be melted to form a film, thereby improving bather properties of the nonwoven structure.

A residual stress in a PZT type ferroelectric film 12 formed on a substrate body 11 by a sol-gel process is −14 MPa to −31 MPa, and the ferroelectric film 12 is crystal oriented in a (100) plane.
