Light weight polythene mailing bags are mailing bags which we consider to be below 50mu or 200gauge in their thickness. The thickness of a polythene mailing bag is measured in micron ( a linear measurement, 1/1000 of 1mm (0.001mm)) or gauge ( imperial equivalent of micron, 1/1000th of an inch (0.001"), thus 1 micron = 4 gauge etc (approx.)
Sharp objects such as metal or rigid plastics which have sharp edges or corners will puncture polythene! However the thicker the polythene the better the puncture resistance will be
We consider the average trade industry standard thickness of a polythene mailing bag to be 60mu or 240 gauge. We recommend you try a free sample for suitability!
MANUFACTURING TRADE TOLERANCES ON MAILING BAGS
Specification: All sizes and thicknesses are approximate. Standard tolerances are in line with industry standards. However, note in particular that bag width may vary by +/-3mm or +/-3% and bag depth by +/-3mm or +/-3% which ever is the greater. Where size is critical, a sample of the product to be packed must be submitted to us in order to agree size tolerances before the acceptance of your order.
