The invention relates to an article based on a mixture of polyamide and polyolefin, which article includes at least one weld line due to multi-port injection molding, said article characterized in that the ratio of the viscosities of the polyolefin to the polyamide, measured at a shear rate higher than 100 s,, is greater than 0.70, and that the quantity of polyamide is sufficient for the elongation at break to be greater than 10%. A typical application is the production of an injection molded automobile fender.

The present invention relates to a film (A) consisting of a mixture comprising at least one polyamide and at least one polyolefin, the said film being placed on agricultural land into which a fumigant is injected. According to a first variant, the invention also relates to a film comprising the above layer (A) and a layer (B) consisting essentially of a polyolefin. According to a second variant, the invention also relates to a film comprising the above layer (A) placed between two layers (B). A coextrusion binder may optionally be placed between the layers (A) and (B) in the two variants. The invention also relates to a process for the treatment of soils by fumigation.
