Which bag thickness is best for your needs?

Polyethylene (PE) and Polypropylene (PP)

For a plastic bag (PE or PP), the thickness is measured in microns (µm). One micron corresponds to one-thousandth of a millimetre (0.001 mm). The thickness of a plastic film is calculated by measuring a single layer of the film. The higher the number of microns, the stronger and more resistant the bag will be. A thin bag is suitable for lightweight products, while a thicker bag is required for heavier or bulkier items.

PAPER

For paper bags, the term used is grammage (g/m²). This measures the weight of the paper per square metre. It’s calculated by weighing a sheet of paper that’s one square metre in size; the higher the grammage, the denser and stiffer the paper will be. A lighter paper is ideal for small or flat items, while a heavier paper offers better protection for heavier or more fragile products.
