Widely used and relatively cheap sacks but also includes sacks that have an insecticide treatment within their fabric. There are 3 common types of open weave sacks:
| Jute sacks: |
Polypropylene sacks:
Made from woven polypropylene strands. Relatively cheap and may be coated so that they have a non-slip surface, so taller stacks can be built. The polypropylene may include a UV stabiliser, this promotes a long life. |
| Insecticide treated polypropylene sacks:
An open weave polypropylene sack, with non-slip surface and UV stabilisation, that includes an insecticide treatment within the weave. This treatment kills insects that make contact with the sack surface. |
