Abstract: The present invention provides a resin composition used for peelable coating and compounding process thereof. The composition includes the following components: (a) 100 parts by weight of film-forming resin containing at least one acrylic resin; (b) 0.1-40 parts by weight of at least one separating agent, which is polypropylene glycol or glycerin fatty acid ester or their mixtures; and (c) 40-60 parts by weight of at least one solvent. The peelable coating formed from the resin composition has excellent water resistance and excellent peeling performance even under the condition of prolonging storage period.

Abstract: Disclosed is a method for improving the barrier properties of polyethylene films. The method comprises mixing a substantially linear, high density polyethylene with a nucleating agent and converting the mixture into a film. The film made by the method of the invention has at least a 15% improvement on the water vapor barrier property and/or in the oxygen barrier property compared with the control film made from the same substantially linear, high density polyethylene but does not contain the nucleating agent.

Abstract: A cellulose acylate film includes a cellulose acylate; and a polyester diol having a hydroxyl group at each of the both terminals in an amount of 5 mass % or more based on the amount of the cellulose acylate.
Abstract: To provide hard coat films having high hardness, and uniform durability against scratching and high flatness even with a small thickness and a large width, and to provide a method producing the same. The hard coat films are provided with an actinic ray curable resin on a cellulose ester film thereof, the cellulose ester film containing a UV absorber and 2 or more plasticizers. One of the plasticizers is a polyalcohol ester type and the other one is a non-phosphate ester type. The cellulose ester film is produced by biaxially stretching of a cellulose ester film with a total acyl substitution degree ranging from 2.6 to 2.9, a number average molecular weight ranging from 80,000 to 200,000, and a ratio of a weight-average molecular weight to a number average molecular weight ranging from 1.4 to 3.0.
