In an outer package material that is for electricity storage devices and has a structure in which at least a base material layer, a first adhesive layer, a metal foil layer, a second adhesive layer, and a sealant layer are stacked in sequence, a composition containing an isocyanato group and a (meth) acryloyl group and further containing an acid-modified polyolefin (component 1), an active energy ray polymerization initiator (component 3), and a solvent (component 4) is used as a composition for adhesives to form the second adhesive layer.

The present application provides a package structure for a chemical system, which comprises an inner glue frame and a first outer glue frame. The inner glue frame forms an accommodating space for accommodating a chemical system. The first outer glue frame is further disposed outside the inner glue frame and used for isolating the ambient environment and thus avoiding the influence of the ambient environment on the chemical system. A second outer glue frame is further disposed for avoiding damages such as side bumps and falls of the chemical system or contact with foreign metals. Thereby, the performance of the chemical system can be maintained.

The present invention provides an outer package material for all-solid-state batteries, said outer package material being composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer, a bonding layer and a thermally fusible resin layer in this order, while being suppressed in delamination in a high temperature environment (specifically, separation of the barrier layer and the thermally fusible resin layer from each other in a high temperature environment). An outer package material for all-solid-state batteries, said outer package material being composed of a multilayer body that is sequentially provided, from the outer side, with at least a base material layer, a barrier layer, a bonding layer and a thermally fusible resin layer in this order, wherein the thermally fusible resin layer is formed of a polybutylene terephthalate film, and the boding layer is formed of a cured product of a resin composition that contains at least one of a polyester and a polycarbonate, and at least one of an alicyclic isocyanate compound and an aromatic isocyanate compound.

The present disclosure relates to a cushioning article comprising a non-syntactic polymeric foam layer; and a plurality of spacer elements arranged within the polymeric foam layer, wherein each spacer element is at least partly embedded into the polymeric foam layer, and wherein each spacer element has a size greater than 200 micrometers.
