Oriented polypropylene film with improved blocking resistance
The present disclosure is directed to a film formulation that resulted in a substantially non-migratory cold seal release film with improved blocking resistance. Specifically, the multilayered biaxially oriented polypropylene film can include a core layer of polypropylene homopolymer; a first outer layer on one side of the core layer that can be suitable for sealing, printing, or coating; and a second outer layer on the opposite side of the core layer that is a blocking resistant layer comprising thermoplastic polymers which reduce blocking tendency.
STRETCH FILM COMPRISING A SLIP SKIN LAYER
Methods and means for producing a stretch film comprising a slip skin layer are provided. In one example embodiment, a stretch film having a slip skin layer is provided having a variable and scalable coefficient of friction. A stretch film comprising a cling layer and a slip skin layer is also provided, in which the cling layer further with includes a polyethylene-based elastomer blended into a low density polyethylene, and the slip skin layer includes an ultra-high molecular weight polysiloxane polymer. Consequently, the slip skin layer has a very low coefficient of friction while the cling layer retains a relatively high co-efficient of friction.
WEATHERPROOF RAMP DOOR
An RV ramp door is hingedly connected near the vehicle floor for selective opening and closing by a user. A weather-resistant construction of a ramp door includes an inner foam body having an inner face and an outer face, a ramp door inner surface, a ramp door outer surface, a first layer of thermoplastic composite material disposed between the inner face of the foam body and the ramp door inner surface, and a second layer of thermoplastic composite material disposed between the outer face of the foam body and the ramp door outer surface. The ramp door inner surface may be a slip-resistant material, and the ramp door outer surface may be a fiberglass panel. The ramp door may include one or more weep holes for releasing any trapped liquid.
Curative
A curative for epoxidized plant-based oils and epoxidized natural rubber is created from the reaction between a naturally occurring polyfunctional acid and an epoxidized plant-based oil is disclosed. The curative may be used to produce at least one of six different materials, wherein each type of material may be configured as a thermosetting elastomer that is crosslinked with β-hydroxyester linkages. The materials may be configured as a leather-like material, a foam material, a molded elastomer, a coating, an adhesive, and/or a rigid or semi-rigid material. Illustrative articles made from any combination of the six materials may be recycled using a mechano-chemical process to de-crosslink the thermosetting elastomer.
THERMOPLASTIC PAVEMENT MARKING TAPES
The present disclosure generally relates to non-conformable thermoplastic pavement marking tapes comprising a backing and an adhesive layer adjacent to the backing. In some embodiments, the backing includes an ionic copolymer. In other embodiments, the non-conformable backing has an inelastic deformation of less than 10% at 25° C. In some embodiments, the pavement marking tape is heat-moldable.
Foot Pillow
A foot pillow that is a flat cushion for the feet, an apparatus that consists of one or more layers that are combined into one unit that a person can put their feet on. To distinguish from prior art, this foot pillow has multiple strategic layers to elevate the feet from the floor or ground surface. This foot pillow is one to four inches in thickness. A reflective insulated layer is added to reflect the cold from the floor and the warmth of the feet. The top layer may be attached or can be removed for washing.
Weight room lifting platform
Disclosed is a method of adhering a translucent material on top of a central wooden platform of a weight lifting station to make a unitary structure, where the wooden platform or a design positioned between the wooden platform and the translucent material is visible through the translucent material after the translucent material and the wooden platform are adhered together.
Porous sheet, and porous composite
An object of the present invention is to provide a porous sheet capable of satisfy both the properties of fitting, preventing tightening, and providing comfort immediately after wearing or at a standstill/at rest and the properties of tightening, fixation stability, and providing comfort during exercise such as sports at the same time, as well as a porous composite comprising the porous sheet, or particularly, a porous sheet and a porous composite for clothing, health products, medical supplies, and sporting goods. The present invention relates to a porous sheet made of a thermoplastic elastomer composition (A), having a plurality of slits and/or pores, and having a porosity of 5 to 50%, an anisotropy of 10% or more, and a stretching stress relaxation rate of 40% or less after being stretched by 500% and held for 60 seconds.
Multilayer films and laminates containing slip agents
Provided is a coextruded multilayer film. The coextruded multilayer film has at least two layers, including a sealant layer and a second layer in contact with the sealant layer. The sealant layer contains (A) a first ethylene-based polymer having a density from 0.865 g/cc to 0.930 g/cc and a melt index from 0.5 g/10 min to 25 g/10 min; (B) an unsaturated primary fatty acid amide having a melting point of 100° C. or less; and (C) a diprotic fatty acid having a melting point greater than 100° C. and a decomposition temperature greater than 200° C. The second layer contains a second ethylene-based polymer. Also provided is a laminate containing said sealant layer.
