Laminated tube container

摘要

A laminated tube container has the body comprising a sheet material comprising a substrate, a silicon oxide deposited layer, a heat buffer layer and an extruded coating layer of a thermoadhesive resin which are successively formed in a laminate. The heat buffer layer prevents cracks from being produced in the silicon oxide deposited layer by the heat coming when the extruded coating layer of a thermoadhesive resin is laminated. The heat buffer layer is preferably formed by dry lamination or non-solvent lamination which requires no heating. An anchor coat layer may optionally be provided between the heat buffer layer and the extruded coating layer of a thermoadhesive resin so that the adhesion strength between these layers can be improved.
