What can I use Transpack Black Polybags for?

Our black bags are ideal for packaging your items securely and confidentially, as they are opaque. Ideal for light sensitive products, medical equipment and food applications. You can also use them to colour-code products. They are commonly used in factories, departments and warehouses, and are often used to wrap tools or other smaller items. Because they are made from food safe film, they can hold food products, as well as other objects.

How strong are Black Polythene bags heavy duty?

At 500 gauge, they are very strong, which makes them ideal for sharp-edged objects or awkwardly-shaped items.

How to measure a polythene bag ?

These bags are measured as follows: width first, then length. So this bag is 178mm wide by 406mm long.

Please note sizes can vary by a few mm due to manufacturing tolerances - Width +/- 3mm or 2%, Length +/- 6mm or 2%, Gauge +/- 10%. This means that the sizing could vary very slightly between batches.
