  1. What are Woven Polypropylene bags
    1. Woven means that the bags is made through a weaving process e.g. by joining multiple threads in two directions (horizontally and veritically) – also known technically as warp and weft. These joined/woven threads form a fabric similar to that used in your clothes (but of course in this case the tapes/threads are wider).
    2. In the plastic woven industry the film is first extruded by an extrusion machine and then it is slit/cut into rows of threads or filaments. These are then made into bobbins for the purpose of weaving into the fabric/sheets or cloth and made into so many common products e.g. tarppaulins, geotextiles, ground covers, woven bags etc…
    3. Polypropylene, which is also known as PP for short name is a kind of thermoplastic resin material that is produced by the polymerization of propylene.
    4. Polypropylene has multiple properties that allow it to work well for the woven sack – it can be melted, cooled and also mixed with other additives to allow for a strong elastic filament tape to be produced.
