A film for packaging a product that has a pharmaceutical active agent includes a product-contacting sealing layer. The product contacting layer includes at least 90 wt. % of an ethylene norbornene copolymer having a glass transition temperature in a range from 50° C. to 110° C. The pharmaceutical active agent comprises a Hansen Solubility Parameter for the product-contacting sealing layer of 0.5 or greater.

Embodiments herein relates to a Bisphenol A-free multi-layer biaxially oriented polyester (BOPET) film, for lamination on metal sheets, which could be used for food containers. The BOPET film has at least one outer release layer, which aids in the release of food, such as a high protein food source, when food is cooked and sterilized in direct contact with the outer release layer. The BOPET film can be laminated to metals used in the manufacture of food containers with the outer release layer being exposed to allow a direct food contact between the surface of the outer release layer and food. More particularly, the invention relates to a novel outer release layer resin composition comprising an ultra high molecular weight siloxane polymer and a polyethylene trephthalate resin; and an alkali-metal phosphate and a phosphoric acid compound added, during polymerization of the outer release layer resin composition, as a catalyst/additive package to the ingredients forming the outer release layer resin composition. A wax component can be added in the outer release layer, for more robust release performance.

The present invention provides a color migration blocking composition, comprising: 15 parts to 45 parts by weight of a phenoxy resin; 5 parts to 40 parts by weight of an elastomer-modified epoxy resin; 1.5 parts to 7.0 parts by weight of a curing agent; and 30 parts to 65 parts by weight of a solvent, based on the total weight of the color migration blocking composition. The color migration blocking film formed by the color migration blocking composition has a good effect on blocking color migration and a good adhesion strength; therefore, when a color migration blocking laminate comprising the color migration blocking film is applied to a fabric, not only the unnecessary discoloration can be avoided and the softness of the fabric can be maintained, but also the processing cost is reduced, thereby promoting the value of the product.

A method of preparing an elastomer membrane with high water pressure resistance includes the following steps: preparing a dry material by subjecting first thermoplastic polyurethane (TPU) powder/particles to a drying treatment; preparing a first mixture by mixing the dry material thoroughly with one or a mixture of at least two of diethylenetriamine, diethylaminopropylamine, and diaminodiphenylmethane; preparing a second mixture by mixing an initiator thoroughly with the first mixture; preparing a first membrane layer from the second mixture; and preparing a second membrane layer and a third membrane layer through the above steps such that the second membrane layer and the third membrane layer are sequentially formed on the first membrane layer.

A metallic lustrous member with radio wave transmissibility is provided, which is capable of being easily produced, while ensuring a structure in which not only chromium or indium but also any of some other metals such as aluminum is formed as a metal layer on a continuous surface of any of various materials, and also an article using the member is provided. A production method for a metallic lustrous member with radio wave transmissibility, which is capable of easily forming, as a metal layer, not only chromium or indium but also any of some other metals such as aluminum, on a continuous surface of any of various materials. The metallic lustrous member comprises a substrate having radio wave transmissibility, and an aluminum layer formed directly on a continuous surface of the substrate. The aluminum layer has a discontinuous region including a plurality of separated segments which are mutually discontinuous.

A rubber hose with a fixing bracket includes an inner rubber layer defining a hollow portion, first and second braided layers formed on the inner rubber layer, and an outer rubber layer formed on an outer periphery of the second braided layer.

A three-layer composite paper straw and a method for producing the same are revealed. Basically the paper straw is made from composite paper with three layers of composite paper spirally wound and adhered in a staggered and overlapping manner. A first layer of paper, a second layer of paper and a third layer of paper of the three layers of composite paper form the outermost layer, the intermediate layer and the inner layer of the paper straw respectively. The first and the third layers of paper are stone paper while the second layer of paper is long fiber pulp paper. The three layers of paper are stacked on top of one another in turn with the long side thereof overlapping like tiles and then adhered to one another. The paper straw is eco-friendly, recyclable, with good structure strength and easy to produce.
