The paper sack making machines are designed to efficiently produce large quantities of paper bags

These machines consist of a series of interconnected components that work together to transform flat kraft paper into finished valve bags. The process begins with feeding the paper into various processing units, followed by printing, tubing, bottom pasting, and other processes to shape the bags to the desired size and form.

Our equipment is widely used in industries requiring the packaging of powdered or granular materials, including food powders, chemicals, fertilizers, synthetic materials, pharmaceuticals, and minerals. Additionally, oversized valve bags are commonly used in industries like carbon black and ultra-fine nano-powder packaging.
