An easily recyclable container is obtained by subjecting a sheet which is a laminate of a plurality of layers, to vacuum forming and/or pressure forming. The sheet has two adjacent layers (11,12) which are chosen to give the minimum peeling strength and to be manually separable into two portions at the interface of the two adjacent layers. A film portion (F) of the sheet present from the interface of said two adjacent layers (11,12) to the inner surface of the container (1) and the sheet portion (S) of the sheet present from said interface to the outer surface of the container (1), and the peeling strength required for peeling of the film portion F from the sheet portion S is set at 2 to 45 g/15 mm (width). This container (1) is easily recyclable because, after use, the thin film (F) constituting the inside surface of the container (1) can be easily peeled by manual action, e.g. by pulling a tongue-shaped part (5) associated of the film (F), and left-overs in the container can be discarded by being wrapped by the separated film. After stripping the film (F) there is no need of washing the container, and so the main portion of the container is recoverable with the minimum of trouble on the part of the consumer or the recycler. <IMAGE> <IMAGE> |
