An object is to provide a base paper for paper tubes that has lower environmental impact and is used for manufacturing of paper tubes offering excellent water resistance. As a solution, a base paper for paper tubes is provided, wherein: it has two or more but no more than five paper layers; the paper layers are bonded by a water-soluble or water-dispersible adhesive; and its elution rate is 2.0 percent or lower.

A laminate, containing two or more polyolefin resin layers, wherein at least one polyolefin resin layer (A) contains a cellulose fiber including a cellulose fiber having a fiber length of 0.3 mm or more dispersed in the layer; a content of the cellulose fiber in the polyolefin resin layer (A) is 1% by mass or more and less than 60% by mass; and wherein a polyolefin resin layer (B) different from the polyolefin resin layer (A) is laminated in contact with the polyolefin resin layer (A).

Disclosed are compositions and methods for multilayer films, which, in one embodiment may comprise a core layer comprising at least 50 wt. % of high-density polyethylene. Further, the multilayer film may include a first skin layer consisting essentially of one or more ethylene-propylene copolymers. Further still, the multilayer film may include a second skin layer consisting essentially of one or more ethylene-propylene-butylene terpolymers. And yet further, the multilayer film may be oriented in at least one direction, and at least two layers of the multilayer film are coextruded.

A breathable thermoplastic polymer film may be produced and adapted for use as a breathable diaper backsheet. The film may include a blend of LLDPE, mLLDPE and calcium carbonate, and may have improved tear strength and melt strength such that instances of tears or break offs during the machine direction orientation portion of the production process are significantly reduced or eliminated. In addition, the film may have sufficient tear strength to permit omission of CDI processing needed to strengthen weaker prior art films. In this regard, undesired streaking of colors or printed aspects of the film may be reduced or avoided completely.

A thermoplastic film which exhibits elastic-like behavior along at least one axis when stretched or elongated and then released. The thermoplastic film comprises a plurality of raised rib-like elements extending in a direction perpendicular to a main surface of the thermoplastic film. The thermoplastic film further includes a plurality of web areas positioned about the plurality of raised rib-like elements. The plurality of raised rib-like elements and plurality of web areas are arranged in a complex pattern. The complex pattern provides visual and tactile cues as the films are stretched or elongated. The complex pattern can cause the thermoplastic film to have a complex stretch profile.

A multilayer film comprises first, second, and third layers. The first layer comprises at least one aromatic polyester, and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is thermoplastic and has a loss modulus at 1 hertz and 25° C. of less than or equal to 60 megapascals and comprises a thermoplastic elastomer and a polyamide. The third layer contacts the second layer opposite the first layer and has a loss modulus at 1 hertz and 25° C. of at least 70 megapascals. The second layer is sandwiched between the first and third layers. A method of making the multilayer film by coextrusion is also disclosed.

Golf balls having covers made of thermoplastic polyurethane compositions are provided. Multi-piece golf balls can be made. Polyurethane primer coatings and polyurethane top-coatings are applied to the thermoplastic polyurethane cover. Different coating methods can be used. Isocyanate-rich and polyol-rich polyurethane coatings can be applied. In one embodiment, the golf ball can be treated with a multi-functional isocyanate prior to applying the coatings. The polyurethane cover composition and surface coatings can further include catalysts, ultraviolet (UV)—light stabilizers, and other additives. Heat is used to cure the coatings. The coating methods have many benefits and the finished balls have good physical properties.
