Surface treatment for tape adhesion and ultraviolet stability
A surface-treated polymer film is disclosed. The film has a polymer substrate having a first surface and an opposing second surface and a primer applied to the first surface of the substrate. The primer is a cross-linked acrylic polymer or other suitable polymer. A method of insulating a surface with an insulation material constructed from the surface-treated polymer is also disclosed.
Bisphenol A and aromatic glycidyl ether-free coatings
Disclosed are Bisphenol A (BPA), Bisphenol F, Bisphenol A diglycidyl ether (BADGE), and Bisphenol F diglycidyl ether (BFDGE)-free coating compositions for metal substrates including an under-coat composition containing a polyester (co)polymer, and an under-coat cross-linker; and an over-coat composition containing a poly(vinyl chloride) (co)polymer dispersed in a substantially nonaqueous carrier liquid, an over-coat cross-linker, and a functional (meth)acrylic (co)polymer. Also provided is a method of coating a metal substrate using the BPA, BPF, BADGE and BFDGE-free coating system to produce a hardened protective coating useful in fabricating metal storage containers. The coated substrate is particularly useful in fabricating multi-part foodstuffs storage containers with easy-open end closures.
Composition for coating polymer films, coating process and composite materials obtained
The invention relates to a composition intended for coating polymer films, making it possible to improve the adhesion between the film and a final coating, and to confer good barrier properties on the coated film. The coating composition comprises at least one acrylic and/or methacrylic polymer which has a gel content of at least 50% by weight, relative to the total weight of acrylic and/or methacryclic polymer, at least one crosslinking agent and at least one polyester comprising sulphonyloxy groups, which is water-soluble or water-dispersible.
Optical reflection films
Films useful as optical reflectors are prepared by coating a sheet of polyethylene terephthalate or other thermoplastic with acrylic polymer, white pigment, and optionally other additives such as impact modifiers, matting agents and UV stabilizers.
Antimicrobial, molded laminate shopping cart part and method of manufacturing same
An antimicrobial, molded laminate shopping cart part and method of manufacturing same are provided. The part, such as a small child seat, includes a structural carrier made from a thermoplastic resin and having an outer surface. The part further includes a formed plastic film sheet having upper and lower surfaces. The lower surface is bonded to the outer surface of the carrier. The film sheet includes an outer clear plastic layer including at least one antimicrobial agent disbursed throughout the plastic layer. The antimicrobial agent exhibits controlled migration through the clear plastic to the outer surface of the clear plastic layer.
Shrink film for label
A shrink film comprising a core layer comprising a glycol modified polyester, the core having an upper and lower surface; an upper skin layer disposed on the upper surface of the core layer and a lower skin layer disposed on the lower surface of the core layer, the skin layers each individually comprising (a) a resin material; and (b) an antiblocking agent.
Multilayer structures containing biopolymers
The invention relates to a multi-layer structure having at least one inner layer containing an alloy of a biopolymer and an acrylic polymer and at least one outer layer containing a thermoplastic or thermoset polar polymer matrix. The combination of outer polar layer and an inner biopolymer/acrylic layer provides improved properties, such as improved adhesion, and improved mechanical properties. The multi-layer structure may be in the form of a sheet, a film, a tube or pipe, or a profile, and could be used by itself or as a cap-layer over a substrate.
Co-Extruded Multi-Layer Tube for Use in Forming Flexible Bags
A multilayer film including a barrier layer, a sealing layer, and an alcohol barrier layer. The alcohol barrier layer includes cyclic olefin copolymer and is positioned between the barrier layer and the sealing layer. The multilayer film can be used to form a pouch for containing an alcohol-based hand sanitizer.
Composite Thermoplastic Laminate
A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.
Heat-shrinkable multilayer film and heat-shrinkable label
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.
