Abstract: According to one or more embodiments of the present disclosure, a coated film may be made by a process that may include applying an uncured polyurethane precursor between a polyolefin film and a release liner such that a first surface of the release liner is in contact with the uncured polyurethane precursor, curing the uncured polyurethane precursor to form a cured polyurethane layer positioned between the polyolefin film and the release liner, and removing the release liner to form the coated film comprising the polyolefin film and the cured polyurethane layer. The first surface of the release liner may have an optical finish. The curing may impart an optical finish to the cured polyurethane layer substantially similar to the optical finish of the first surface of the release liner.

Abstract: A composition of matter that exhibits two phases at lower temperatures (for example, less than about 50° C.) but only one-phase at higher temperatures (for example, above about 90° C.) is disclosed. The compositions comprise a low viscosity base oil which is a hydrocarbon oil and the high viscosity base oil which is a triblock polyalkylene glycol derived from a copolymer of 1, 2-propylene oxide and 1, 2-butylene oxide in which the PO/BO ratio is from 25/75 to 90/10 percent by weight and has a polymerization sequence of PO-BO-PO.

Abstract: Polymer blends, films, and coated substrates that include the polymer blends. The polymer blends include at least 90% by weight low density polyethylene polymer and from 1 to 10% by weight ionomer. The LDPE polymer has a melt index (I2)from 2 g/10 mins to 6 g/10 mins, and a molecular weight distribution from 5 to 11 as determined by a conventional gel permeation chromatography method. The ionomer includes an ethylene acid copolymer, in which from 15% to 70% of acid groups are neutralized by sodium cation based on the total number of acid groups in the acid copolymer. The ethylene acid copolymer is the polymerized reaction product of: at least 50% by wt. ethylene, from 2 wt. % to 40 wt. % of monocarboxylic acid monomer, and from 0 to 20 wt. % of alkyl acrylate, based on the total wt. % of the monomers present in the ethylene acid copolymer.
