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.
