摘要
A multilayer coextruded thermoplastic sheet consisting of a first layer (121) including at least one band (126) of a first thermoplastic polymer composition alternating with at least one band (127) of a second thermoplastic polymer composition, and a second layer (128) consisting of the first thermoplastic polymer composition, the second layer adjoining the first layer. Such sheets, which can be formed by coextrusion of the various polymer layers, are for example for viewing the contents of the tubes. If the sheet includes more than one of each of the bands (126, 127), it can be cut in various ways to form tubes with a variety of arrangements of stripes. IMAGE
