Application:
Square bottom bag: Square bottom bag is often used to package various chemical products, such as powder, granules, liquids, etc. Its sealing performance and load-bearing capacity can effectively prevent product leakage and damage.
Three papers and one film: Used to package chemical products, such as fertilizers, mineral products, etc., it is favored for its convenient filling, neat stacking, convenient transportation, and beautiful appearance. Used to package building materials, such as tile plastic bags, etc., to ensure the quality of products during transportation and storage.
Valve bag: Valve bag is often used to store and transport powdered chemicals, plastic granules and other materials, meeting the strict requirements of chemical companies for material packaging. It is widely used in the packaging and transportation of building materials such as cement, mortar, gypsum, etc., to ensure product quality and safety.
Kraft paper bag: In the industrial field, kraft paper bags can be used to package heavy objects such as cement, chemical raw materials, and building materials because of its excellent strength and durability.
Features:
Square bottom bag: The bottom of the square bottom bag is designed to be flat, and it can stand firmly like a paper box, which is convenient for storage and beautiful in appearance. . The printing is exquisite, providing ample space for manufacturers and designers to describe products and design patterns. In addition, square bottom bags can also be personalized according to customer needs. Functional design, such as pressure resistance, waterproof, light blocking and other characteristics.
Three papers and one film: Due to the thick film layer, the bag body has high strength and impact resistance, which can effectively prevent the packaging bag from being damaged. The bag body adopts ultra-micro air permeability design, less floating dust, and good moisture-proof performance.
Valve bag: The valve bag is made of multi-layer paper base or plastic woven material, with excellent moisture-proof performance and strong load-bearing capacity, and a low breakage rate. It is suitable for packaging various powdered or granular materials. The unique design makes the filling process fast and efficient, which can significantly improve packaging efficiency. Its self-sealing ability enables the filling equipment to complete the sealing quickly, reducing manual operation and improving production efficiency. The top valve design of the valve bag enables the material to be automatically sealed after filling, avoiding material leakage, and facilitating transportation and storage.
Kraft paper bags: Kraft paper bags have high strength and toughness, can withstand large weight and pressure, and are not easy to break or tear. Its fibers are long and tightly interwoven, with high tensile strength and tear strength, and are suitable for loading heavy objects. In addition, kraft paper bags also have good stiffness, can maintain a stable bag shape, and are easy to carry.
Advantages:
Square bottom bag: The design of the square bottom bag makes it take up less space during storage and transportation, which can save transportation costs compared to bags of other shapes.
Three papers and one film: In the three-paper and one film structure, the interlayer polyethylene film (PE film) has extremely low moisture permeability, which can effectively block the contact between water vapor and materials and extend the storage time of materials. The outer layer is made of kraft paper, and the inner layer is made of paper bag paper, which provides good load-bearing and tensile strength, and can well protect the packaging from falling or damage.
Valve bag: The valve bag has excellent sealing performance, which can effectively prevent the leakage of items or the intrusion of external impurities, and ensure the integrity and safety of the items. In addition, valve bags reduce dust generation and reduce air and water pollution by sealing the bag.
Kraft paper bag: Kraft paper has high strength and toughness. This structure gives the kraft paper bag high tensile strength and tear strength, capable of withstanding heavy weight and pressure, and is suitable for packaging and transporting various heavy objects.
