Abstract
Abstract The invention relates to synthetic plastic sheeting which is in the form of a flexible synthetic plastic film of material which has a biocide incorporated therein. The biocide can serve to inhibit the growth of different micro-organisms that cause bio-deterioration and, as such, the film can be used for packaging of or the covering, or protection of, products and objects that are exposed to bio-deterioration. The sheeting can also be provided in a sleeve form (12) permitting fitting on timber poles, for covering regions of poles to be disposed underground, in use, thereby protecting these regions against bio-deterioration.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
43 words
Flexible synthetic plastic sheeting suitable for packaging of subject matter, covering of subject matter and protection of subject matter, which comprises a flexible synthetic plastic film of material which has a biocide for inhibiting the growth of micro-organisms that cause bio-deterioration incorporated therein.
Claim 2
Dependent Claim
44 words
Flexible synthetic plastic sheeting as claimed in Claim 1, characterized in that the synthetic plastic film having a biocide incorporated therein is an extruded film having the biocide incorporated into the plastic material of which the film is formed, prior to the extrusion thereof.
Claim 3
Dependent Claim
45 words
Flexible synthetic plastic sheeting as claimed in Claim 2, characterized in that the synthetic plastic material of which the film is formed is provided in granular form and the biocide is incorporated therein in a powder form prior to extrusion of the synthetic plastic film.
Claim 4
Dependent Claim
44 words
Flexible synthetic plastic sheeting as claimed in Claim 2, characterized in that the synthetic plastic material of which the film is formed is provided in granular form and the biocide is incorporated therein in liquid form prior to extrusion of the synthetic plastic film.
Claim 5
Dependent Claim
41 words
Flexible synthetic plastic sheeting as claimed in any one of the preceding claims, characterized in that the synthetic plastic material of which the film is formed is one of low density polyethylene, linear low density polyethylene, polyvinyl chloride and cross-linked polyethylene.
Claim 6
Dependent Claim
31 words
Flexible synthetic plastic sheeting as claimed in any one of the preceding claims, characterized in that the biocide incorporated in the material of the synthetic plastic film is a dry-film biocide.
Claim 7
Dependent Claim
33 words
Flexible synthetic plastic sheeting as claimed in any one of the preceding claims, characterized in that the biocide incorporated in the material of the synthetic plastic film includes urea derivatives, isothiazolinone and glycols.
Claim 8
Dependent Claim
29 words
Flexible synthetic plastic sheeting as claimed in any one of the preceding claims, characterized in that the synthetic plastic film is specifically adapted for use in different predetermined applications.
Claim 9
Dependent Claim
31 words
Flexible synthetic plastic sheeting as claimed in Claim 8, characterized in that the flexible synthetic plastic film is formed into the configuration of a bag for packaging foodstuffs, or the like.
Claim 10
Dependent Claim
67 words
Flexible synthetic plastic sheeting as claimed in Claim 8, characterized in that the flexible synthetic plastic film is provided in the form of a liquid impervious non-bio-degradable elongated sleeve that can be fitted onto a timber pole to be supported in the ground for covering an area thereof that is exposed to sub-soil decay caused by a range of common and widespread fungi which inhabit the ground.
Claim 11
Dependent Claim
52 words
Flexible synthetic plastic sheeting as claimed in Claim 10, characterized in that the elongated sleeve formed of the film has predetermined dimensions and shrinkage properties, permitting the sleeve to be fitted onto a pole having a predetermined diameter and to securely locate the sleeve by being shrunk onto the pole by heating.
Claim 12
Dependent Claim
77 words
A synthetic plastic sleeve formed of synthetic plastic sheeting which comprises a liquid impervious, non-bio-degradable flexible synthetic plastic film of material which has a biocide for inhibiting the growth of micro-organisms that cause bio-deterioration, incorporated therein, the sleeve being dimensioned to fit onto a predetermined diameter timber pole for covering a desired area thereof and having shrinkage properties to permit secure location of the sleeve on the timber pole by being shrunk onto the pole through heating.
Claim 13
Dependent Claim
44 words
A synthetic plastic sleeve as claimed in Claim 12, characterized in that the synthetic plastic film having the biocide incorporated therein is an extruded film having the biocide incorporated into the plastic material of which the film is formed, prior to the extrusion thereof.
Claim 14
Dependent Claim
46 words
A synthetic plastic sleeve as claimed in Claim 13, characterized in that the synthetic plastic material of which the film is formed is provided in granular form and the biocide is incorporated therein in a powder form prior to the extrusion of the synthetic plastic film.
Claim 15
Dependent Claim
45 words
A synthetic plastic sleeve as claimed in Claim 13, characterized in that the synthetic plastic material of which the film is formed is provided in granular form and the biocide is incorporated therein in liquid form prior to the extrusion of the synthetic plastic film.
Claim 16
Dependent Claim
47 words
A synthetic plastic sleeve as claimed in any one of Claims 12 to 15, characterized in that the synthetic plastic material of which the film forming the sleeve is formed is of one of low density polyethylene, linear low density polyethylene, polyvinyl chloride and cross- linked polyethylene.
Claim 17
Dependent Claim
35 words
A synthetic plastic sleeve as claimed in any one of Claims 12 to 16, characterized in that the biocide incorporated in the material of the synthetic plastic film forming the sleeve is a dry-film biocide.
Claim 18
Dependent Claim
37 words
A synthetic plastic sleeve as claimed in any one of Claims 12 to 17, characterized in that the biocide incorporated in the material of the synthetic plastic film forming the sleeve includes urea derivatives, isothiazolinone and glycols.
