摘要： Disclosed is a resin laminate comprising: an outer layer formed from a linear polyethylene having a specific density; an inner layer formed from a linear polyethylene having a specific density; and an intermediate layer(s) provided between the outer layer and the inner layer, wherein at least one intermediate layer comprises a linear polyethylene having a specific density different from those of the linear polyethylenes for forming the outer layer and the inner layer; and at least one layer of the outer, inner and intermediate layers is formed from a linear polyethylene composition containing a high-density polyethylene having a specific density. Also disclosed in a container formed from the resin laminate. The resin laminate is excellent in hygienic qualities, transparency, flexibility and heat resistance. The container is hardly distorted even when subjected to a sterilization process under severe conditions, and is excellent in heat resistance, sealing strength, drop strength, transparency and flexibility.
