Coated woven bags are widely used in industries such as chemicals, agriculture, food, and cement. They inherit the high tensile strength of woven bags while also offering the good airtightness and moisture resistance of film bags, making them a typical composite packaging material. Particularly, inner coated woven bags made with cylindrical woven fabric as the base material have strong tensile resistance, excellent airtightness, moisture resistance, and the coated film is less likely to peel off. They can withstand internal pressure well, have an improved appearance without the original荷叶edge of the outer coated woven bags, and maintain their strength without damage. Moreover, they fundamentally solve the primitive process of manual bag flipping in the past. In current technology, the inner film material used to produce inner coated woven bags often employs a 2-layer or 3-layer structure, with the aim of providing a smooth inner surface for the film material while ensuring it is firmly attached to the woven base fabric.

Film-coated woven bags, due to the composite film's effect, offer excellent moisture resistance and also feature high temperature resistance, anti-mold properties, ease of stacking, and non-slip characteristics. For these reasons, they are widely used in numerous industries and fields.
