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.
| Thickness | 12 microns | 20 to 30 microns | 40 to 60 microns | 100 microns | 150 microns |
|---|---|---|---|---|---|
| Uses | ECONOMICAL Protects very light products or bundled products. Approved for food contact. |
ECONOMICAL AND DURABLE Suitable for protecting lightweight, non-fragile products. |
RESISTANT Suitable for moderate-weight products. |
VERY RESISTANT Protects heavy products. |
ULTRA-RESISTANT Perfectly protects very heavy products. |

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.
| Thickness | 33 to 45 g/m² | 60 g/m² | 70 to 90 g/m² | 90 to 180 g/m² |
|---|---|---|---|---|
| Uses | ECONOMICAL For flat or small products. |
