A multilayered structure that includes an olefin resin layer and a gas-barrier layer. An adhesive layer is provided adjoining the olefin resin layer and the gas-barrier layer, the adhesive layer consisting of an acid-modified olefin resin. The acid-modified olefin resin has methyl branches in a number of 10 to 200 per 1000 carbon atoms on a main chain thereof, and has not more than 50 branches that are larger than the methyl groups.

Adhesive for polyolefin and multilayered structure

A packing material for surfactant-containing products includes a solid surface layer () that contains a non-aromatic silicone type polymer and a silicone oil layer () held on the solid surface layer (), wherein the non-aromatic silicone type polymer is at least the one kind of polymer selected from a silicone resin, a silicone-modified olefin resin, silicone-modified polysaccharides and a silicone-modified acrylic resin.

Packing material for surfactant-containing products

A packaging material having a contact surface formed of a thermoplastic resin that is adapted for contacting a viscous content. The contact surface is a mirror surface having a roughness Sa of not more than 100 nm and a water contact angle of not less than 60&#xb0; C. at 20&#xb0; C.

Packaging material

An adhesive for polyolefin used for an extrusion-formed multilayered structure that includes, at least, a propylene type resin layer and an ethylene type resin layer, the adhesive for polyolefin comprising an olefin resin that has methyl branches at a ratio of 10 to 200 per 1000 carbon atoms on a main chain thereof.

A package including a container body () containing a fluid content () with leaving a head space (), wherein the container body () has an inner surface () on which ruggedness is formed entirely, the inner surface () with the ruggedness of the container body () is coated with a lubricating liquid () immiscible with the fluid content (), and the lubricating liquid () is present as a coating layer interposed between the inner surface () and the fluid content (), and the lubricating liquid () for forming the coating layer forms a liquid pool () at a periphery of an upper end face of the fluid content () contained in the container body () in a state of being held upright.
