Abstract: The invention provides a heat-shrinkable thermoplastics packaging film comprising a laminate of two or more individual heat-shrinkable thermoplastics packaging films, where each of the individual films is substantially identical in composition and layer construction. The films are preferably prepared from double wound film, especially biaxially oriented film comprising LLDPE. The invention also provides a process of preparing such a film, comprising: a) providing two layers of heat-shrinkable thermoplastics packaging film, namely a first layer and a second layer, each of the first and second layers having inner and outer surfaces, the inner surfaces being adjacent to each other; b) treating the outer surface of the first layer to enable the first layer to adhere to the second layer; and c) winding the two layers together into a roll, such that the treated outer surface of the first layer adheres to the outer surface of the second layer to form a laminate.
