This product is manufactured using a composite process of kraft paper and PP plastic woven fabric. The outer layer of paper is responsible for printing, and the inner layer of PP material is responsible for bearing the load. The composite layer is made of a mixture of various modified plastics. The bag body has good sealing performance and features high strength, water resistance, and moisture resistance. It is suitable for transporting small quantities of loose powder, granular, and flake-like materials and can be used for long-distance transportation or internal transfer and recycling. It is currently one of the most popular and practical general packaging materials.

Sewn bottom bag

Sewn-bottom bags, also known as open-mouth sewn bags, have their bottoms sealed with special thread by a sewing machine. They are easy to operate when unpacking, and the overall production process is simple, making them suitable for manufacturing enterprises with large production volumes.

Open-top bag with a square bottom

A square bottom bag, also known as an open square bottom bag or single-head glued bottom bag, has a bottom that is folded and glued together. After filling, it is rectangular. A strong bottom patch increases its strength. The flat bottom allows it to stand steadily during filling, preventing spillage. It is environmentally friendly, strong, stable when stacked, and easy to identify. It is mainly used for powdery, granular, and flake-like products in the food raw materials and additives, chemical powders, feed, and plastics industries, and is widely used in the packaging industry.

Block bottom valve bag

Valve bags, also known as spout pouches, are filled from the top or bottom spout using specialized filling equipment. After filling, they automatically form a rectangular shape, offering efficient filling, neat stacking, and convenient transportation. They are widely used for packaging powdery or granular solid materials and flexible items in industries such as powders, chemicals, synthetic materials, pharmaceuticals, and minerals. Extra-large valve bags are widely used in the packaging of meteorological silica and ultra-fine nano-powders. They are currently the mainstream environmentally friendly packaging bags for powders internationally.

Laminated paper-plastic composite bag

Laminated paper-plastic composite bags enhance water and moisture resistance by applying a film to kraft paper, preventing moisture damage and reducing the risk of breakage. The film is made of materials such as PP/PE/OPP, increasing the overall strength of the paper-plastic bag.
