| PVC SHRINK FILM |
Among the basic characteristic that define the PVC shrink film are:
MEAN PRODUCTION CONTROLLED PARAMETERS
| PARAMETER | PRODUCTION RANGE | TOLERANCE |
| Weight (Kg.) | - | +-1%. |
| Width (cm) | 5
to 120 (Folded or Flat) 20
to 120 (Tubular)
|
(Folded).
+1 cm for 5 to 20 cm nominal widths +2 cm for 21 to 60 cm nominal widths +3 cm for more of 60 cm nominal widths (Flat or Tubular). +0.5 cm for 5 to 20 cm nominal widths +1.0 cm for 21 to 60 cm nominal widths +1.5 cm for more of 60 cm nominal widths |
| Gauge (0.00001") |
100 to 250 (for 12 to 20 cm widths) 50 to 250 (for 21 to 120 cm widths) |
+-10% of nominal gauge. |
| Shrink (%) | 10 to 50% (D/M ó D/T) | +-5% add to nominal. |
