Heavy duty 100 micron polythene bags are ideal for warehouse, office & industrial applications. Due to the increased thickness in micron these bags are tough & hardworking. They are a great way to protect your products from dust & dirt & can offer protection from moisture. Approved for food use & manufactured from low density 100 micron / 400 gauge virgin polythene; due to the thickness of the bag it has a slight cloud to the transparency. With heat sealed seams preventing the polythene bag from splitting, our polythene bags can be heat sealed closed or secured with bag ties. Supplied in a dispenser box which prevents wastage & helps to keep your packaging area tidy (refs SP15E & P5740 supplied in a dispenser pouch instead of a box).
