Definitions
- This invention relates to reinforced plastic film which is useful (inter alia) for wrapping pelletised loads.
- elongated plastic film is provided with at least one reinforcing strip of plastic film integral therewith and extending along the length of the film and spaced from its opposite side edges.
- the or each reinforcing strip may be incorporated in the film during manufacture thereof or may be applied thereto after manufacture.
- a particular advantage of the invention is that, if the film is punctured during use, a resultant tear will be stopped from excessive lateral travel by any reinforcing strip which it encounters.
- the plastic film may for example have a thickness in the range of from about 10 to about 100 microns, and each reinforcing strip may have a thickness in the range of from about 10 to about 100 microns.
- Each reinforcing strip may have a width in the range of from about 0.25 to about 2.5 inches.
- the plastic film and each reinforcing strip may be single or multilayer stretch plastic film of any suitable material and may be of the same or different material. Typically, for pelletising loads, the plastic film may be single layer linear low density polyethylene.
- Fig. 1 is a perspective view of a roll of reinforced plastic film in accordance with one embodiment of the invention
- Fig. 2 is a similar view to Fig. 1 but showing an initial portion of the film unwound from the roll,
- Fig. 2 A is a sectional view of the film taken along the line 2A - 2 A of Fig. 2,
- Fig. 3 is a diagrammatic view showing one method of making a reinforced plastic film in accordance with the invention
- Fig. 4 is a similar view to Fig. 3 but showing another method for making a reinforced plastic film in accordance with the invention.
- a roll 12 of reinforced plastic film comprises a length of plastic film 14 wound on a cylindrical core 16 which is conventionally made of laminated paperboard. It will be noted that opposite end portions 18, 20 of the core 16 project a short distance beyond the edges of the plastic film 14.
- the plastic film 14 has three laterally spaced longitudinally extending integral reinforcing strips 22 spaced from the opposite side edges of the film 14. In this embodiment, the reinforcing strips 22 are of the same plastic material and the same thickness as the plastic film 14.
- the reinforced plastic film 14 is especially suitable for wrapping around pelletised loads, and the projecting end portions 18, 20 at the core 16 provide convenient handles for manually holding the roll while the film 14 is being wrapped around a load.
- the integral reinforcing strips 22 not only reinforce the film 14 but also provide stops for any tears which may occur in the film when in use.
- the film 14 may be provided with reinforcing strips 22 during manufacture or after manufacture in a separate operation.
- Fig. 3 shows the film 14 and integral reinforcing strips 22 being extruded from a flat die 24 and passing between rollers 26, 28 before being wound on the core 16.
- Fig. 4 shows the reinforcing strips 22 being extruded from a die
- the core 16 may be omitted so that the roll 12 is coreless, for example as described in U.S. Patent 6,102,213 (Salzsauler et al) issued August 15, 2000, the contents of which are also hereby incorporated herein by reference.
