What is a heavy duty polybag?

This is a clear, polythene bag made of heavy weight or strong film designed to protect your heavier products from moisture and dust, while resisting puncturing. They are open at the top, with the other three sides sealed and the top can be closed by heat-sealing using one of our Impulse sealers, a rubber band, neck tie or tape. These bags are very versatile and are very well made from safe, inert film which they can be used for many applications including food storage. 

What can these bags be used for?

These high quality heavy duty bags are tough, so they’re perfect for protecting your products. In fact, they are the same as the type used by builders to carry sand, so you know they’re strong enough for your heavy items. For example, they are suitable for protecting and packaging mechanical spare parts, gravel, salt and grit.

As these bags are made from food safe polythene, they can also be used to store food items.

How strong are these bags?

These bags are excellent quality, they are designed to hold heavy weight products and protect against puncturing.

How to measure these bags?

These bags are measured as follows: width first, then length. So this bag is 375mm wide by 500mm 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.
