A resin-coated metal sheet for a container includes: a metal sheet; a first resin coating layer provided on an inner face of the metal sheet after forming; and a second resin coating layer provided on an outer face of the metal sheet after forming, wherein a polar component of surface free energy of the second resin coating layer is 3.5 mN/m or more, after the second resin coating layer is subjected to heat treatment at a melting point of the second resin coating layer plus 8 C. for 2 minutes, and a static friction coefficient of the second resin coating layer, at 145 C., is 0.16 or less.

The surface roughness of a polymer film laminated to a metal substrate can be improved through the use of sufficient heating after application of a wax layer to the polymer film. In some cases, a thin liquid film or layer of a waterborne wax dispersion can be applied to the surface of a metal substrate laminated with a polymer film. After heating the polymer film and wax layer to a point at which the polymer film and wax layer begin to become molten, the surface roughness of the polymer film can become improved due to the presence of the wax.

The article further optionally includes two optional layers each independently including a polychlorotrifluoroethylene and/or copolymer of polychlorotrifluoroethylene and vinylidene fluoride, or an ethylene acrylate resin, or a polyester, polycarbonate, polypropylene, polyethylene, or combinations thereof. The article has a clarity of at least about 90% as determined using ASTM D1003-13.

A resin-coated metal sheet for a container includes: a metal sheet; a first resin coating layer provided on an inner face of the metal sheet after forming; and a second resin coating layer provided on an outer face of the metal sheet after forming, the second resin coating layer containing: polyester resin having a melting point of 230 C. to 254 C. as a main component; and a lubricant component, a melting point of the lubricant component being 80 C. to 230 C., an average particle diameter of the lubricant component present on a surface of the second resin coating layer being 17.0 nm or less.

The invention describes the use of magnetic platelet particles as a multifunctional additive to various formulations of polyolefin plastic films usable to fabricate packaging and to provide said packaging with similar barrier properties as aluminium metallizations or other gas barriers, with the added benefit of allowing separation and recovery of the packaging by magnetic means. Such novel additives, films and packaging are environmentally friendly and food-safe, so that after use they can be either recovered for reuse, composted, or dumped in the environment to biodegrade. The invention comprises various types of films comprising the additive and methods to improve the properties of said films.

At least some example embodiments relate to a container including a body and a lid. The body includes a base, a side wall, and an interior region at least partially defined by the base and the side wall. The lid includes a lid wall and a skirt that extends from a periphery of the lid wall. The skirt engages the body to retain the lid on the body. The skirt cooperates with the lid wall to define a cavity. The lid is formed from a laminate including a metal layer and a polymer layer coupled to the metal layer. The polymer layer is disposed inside of the metal layer with respect to the cavity. A portion of the body is disposed inside the cavity when the container is in a closed configuration. At least some example embodiments relate to a forming of manufacturing the lid.

A method for determining a reference value of a wine for feasibility of filling an aluminum can, the method comprising: acquiring a pH, an alcohol concentration, and a free sulfite concentration for multiple kinds of wines; calculating a molecular SO.sub.2 concentration of each of the multiple kinds of wines from acquired values of the pH, the alcohol concentration, and the free sulfite concentration; enclosing the multiple kinds of wines into aluminum cans of an identical type, respectively, thereby obtaining multiple kinds of canned wines; putting the multiple kinds of canned wines in storage and evaluating quality of the canned wines after the storage; and determining an upper limit value of the molecular SO.sub.2 concentration based on an evaluation result obtained from the evaluating.

Provided are a polyester film that is usable for protecting a surface of a metal plate of a construction material, a decorative material, an interior material, an electronic product, etc., and a manufacturing method therefor, and a polyester mold product using the same and a manufacturing method therefor, wherein the polyester film has low orientation and low modulus to have excellent moldability.
