Polybags tolerances
The polythene film extrusion process involves blowing up a molten
bubble of film and then cooling and cutting it to shape. This is
a technically difficult process and is affected by external
conditions (such as heat and humidity) and by the flexibility and
stretchiness of the film. Whilst we strive to obtain exact
dimensions, a degree of manufacturing tolerance is therefore
always required on every product.
Please do not hesitate to contact us to discuss any specific tolerance
required on your job.
-
Width
Plus or minus 3mm (0.125") or 2%, whichever is greater. If you
need a minimum width, please discuss with
us.
-
Length
Plus or minus 6mm (0.25") or 2%, whichever is greater. Please
note that all measurements are cut to cut and will therefore
include a bottom skirt of about 8mm on end weld bags (apart
from grip seal bags where length is measured from the grip seal
to the bottom of the bag).
-
Gauge
Plus or minus 10%.
-
Quantity
For manufactured goods only, Plus or minus 10%.
Please note: our bags are normally manufactured end weld
although we reserve the right to manufacture in side weld unless
a specific request is made for a particular type.
