The basic material used to manufacture plastic woven bags is polypropylene (PP), a thermoplastic synthetic polymer of propylene that has relatively high strength. Pure polypropylene is white while the base color of the bags can be easily changed by adding color to raw PP material. The circular loom is adjusted to weave a plastic cloth tube with a required diameter. Cutting and sewing operations form the final product.

Basic woven PP bags can be used to hold granular material but they are not waterproof. To keep the moisture from getting into the packages, a thin sprayed-on film can be applied on the woven cloth. Bags can also come with custom prints. Multicolor printers can directly print lettering and simple images on the woven bag. However, to make the beautiful full-color packages such as required by consumer-oriented products, the image has to be preprinted on a thin film employing full-color plastic printer. The thin film is then laminated on the woven PP bags.

Polypropylene woven packaging has been used widely in many industries due to its strength and versatility. Most often they can been seen in the packaging of fertilizer, grain, flour, cement, pet food, sand, chemical, etc.
