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

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.
