11458713 · 2022-10-04 · ·

Film laminates containing a layer of a lower melting polyaryletherketone and a layer of a higher melting polyaryletherketone adhered to each other are resistant to heat, wear, moisture, weathering and chemicals and are useful for producing articles such as laminated electronic circuits, flexible heaters, insulated wire and cable, radio frequency identification tags and labeled articles.

Structure for secure containment of information

A structure for secure containment of information (SSCI) that is in the form of a laminate which includes at least two layers. The laminate is constructed to contain information such as a code, serial number, informational feature, encryption key or personal identification number (PIN). The information is located between the layer of the laminate such that the code, serial number, informational feature, encryption key, or PIN is not detectable from outside the laminate. The SSCI is configured to provide access and expose the code, serial number, informational feature, encryption key, or PIN by delaminating at least one layer, thereby indicating that tampering has occurred to the laminate. The SSCI can also function as a public key or private key for a blockchain, to provide access to a physical lock or to provide account access to claim financial value.

Heat-shrinkable label

A heat-shrinkable label made from or containing a terpolymer film containing propylene, ethylene and 1-hexene, wherein the terpolymer has: (i) a content of ethylene derived units ranging from 0.5 wt % to 5.0 wt %, (ii) a content of 1-hexene derived units ranging from 1.0 wt % to 6.0 wt %, (iii) a melt flow rate (MFR) (ISO 1133 230° C., 2.16 kg) ranging from 0.5 to 20 g/10 min, and (iv) a polydispersity index (P.I.) ranging from 2.0 to 7.0.

Clear hot melt adhesives
20220204819 · 2022-06-30 ·

Hot melt adhesives comprising (i) styrene butadiene copolymer, (ii) olefin block copolymer (OBC), and (iii) water white hydrogenated hydrocarbon resin are described. The adhesives exhibit high optical clarity and are relatively clear over a wide range of temperatures. The adhesives also exhibit good adhesion at cold temperatures. Also described are laminates of the adhesive with polymeric films, such as adhesive labels that can be used in labeling containers. In addition, various goods such as containers labeled using the adhesives are described.

ACTIVATABLE WARMING INDICATOR WITHOUT DYE

A temperature exposure indicator includes a reservoir of meltable material having a melting point at an activation threshold of the temperature exposure indicator. The temperature exposure indicator also includes a light scattering material having voids and an indicia overlayed by the light scattering material such that the indicia is initially obscured by the light scattering material prior to the meltable material being exposed to a temperature above the activation threshold. The reservoir is in fluid communication with the light scattering material, such that the meltable material, when exposed to a temperature at or above the activation threshold, is configured to melt and flow into the voids of the light scattering material thereby causing the light scattering material to transition from an obscuring form to a non-obscuring form so that the indicia is viewable through the light scattering material.

HEAT-SHRINKABLE MULTILAYER FILM AND HEAT-SHRINKABLE LABEL
20220258458 · 2022-08-18 ·

The present invention provides a heat shrinkable multilayer film that makes it possible to produce a heat shrinkable label having high seal strength regardless of interlaminar strength, and that also has excellent transparency. The present invention also provides a heat shrinkable label including the heat shrinkable multilayer film. Provided is a heat shrinkable multilayer film including: front and back layers each containing a polyester resin; an interlayer containing a polystyrene resin; and adhesive layers, wherein the front and back layers and the interlayer are stacked with the adhesive layers interposed therebetween, and the adhesive layers each contain a polyester resin having a glass transition temperature of 77° C. or lower.

Method for making a biofabricated material containing collagen fibrils

Described herein is a method for producing a biofabricated material from collagen or collagen-like proteins. The collagen or collagen-like proteins are isolated from animal sources or produced by recombinant DNA techniques or by chemical synthesis. The collagen or collagen-like proteins are fibrillated, crosslinked, dehydrated and lubricated thus forming the biofabricated material having a substantially uniform network of collagen fibrils.

LAMINATE PRODUCTION METHOD

A laminate production method is provided which can sufficiently prevent the occurrence of blocking without causing deterioration in the outstanding characteristics of acrylic block copolymers such as adhesive performance, and can also ensure excellent processability during extrusion. The laminate production method includes a step (1) of bringing raw pellets of an acrylic block copolymer (A) into contact with an aqueous dispersion (C) containing acrylic resin particles (B) and no surfactants, the acrylic block copolymer (A) including at least one polymer block (a1) including acrylic acid alkyl ester units and at least one polymer block (a2) including methacrylic acid alkyl ester units, a step (2) of removing water attached to the pellets and thereby obtaining pellets (D), and a step (3) of preparing an adhesive composition using an adhesive feedstock including the pellets (D) from the step (2), and extruding the adhesive composition to form an adhesive layer and thereby producing a laminate including the adhesive layer and a substrate layer.

Cutting of adhesive materials with water-soluble protective layer

A pre-assembled kit of cut shapes disposed upon a peelable or repositionable adhesive by means of an affixing adhesive protected by a water-soluble coating which is solubilised either prior to and/or on application of the kit to a surface which may be moistened prior to application. When the water-soluble coating is solubilised, in whole or in part, by placing in contact with the moistened surface, it will expose and/or activate, in whole or in part, the pressure-sensitive adhesive beneath the water-soluble coating to the surface to which it is to be applied and the pre-assembled kit will become affixed to the surface. Alternatively, solubilisation of the water-soluble coating may be provided by applying water, preferably warm water, to the water-soluble coating prior to applying the pre-assembled kit to the surface. A method of producing the pre-assembled kit of cut shapes is provided. In preferred embodiments the protective water-soluble coating is substantially a formulation of poly-vinyl alcohol or polyurethane polymers.
