Woven bags are generally white or off-white, non-toxic, odorless, and generally pose little harm to human health. Although made from various chemical plastics, they are relatively environmentally friendly and have a high recycling rate. Woven bags have a wide range of uses, mainly for packaging various goods, and are widely used in industry. Plastic woven bags are made primarily from polypropylene resin, which is extruded, stretched into flat filaments, and then woven and made into bags.
Composite plastic woven bags are made from plastic woven fabric as the base material, laminated using a casting method.
They are used for packaging powdery or granular solid materials and flexible items. Composite plastic woven bags are classified into two-in-one bags and three-in-one bags according to their main material composition.
According to sewing methods, they are classified into sewn-bottom bags, sewn-side-bottom bags, slip-in bags, and glued-sewn bags.
According to the effective width of the bag, they are available in 450, 500, 550, 600, 650, and 700 mm. Special specifications are agreed upon by the supplier and the buyer.
