Kraft paper bags include three-layer, four-layer, and multi-layer bags. These can be coated with a PP film for waterproofing and can be lined with an inner film. They can also be color-printed. They feature a seam-bottomed opening, ensuring environmental protection and hygiene. Multi-layer kraft paper bags are available with a perfect composite of imported and domestic kraft paper, or kraft paper and PP woven fabric. PE plastic bags can be added to the bag, ensuring full food-grade compliance. Choose the packaging that suits you best.
Styles include seam-bottomed opening and glued-bottomed opening. These are the most popular packaging methods for export companies. They are primarily used for packaging chemicals, food additives, feed additives, pigments, milk powder, dry mortar, and other building materials.
Paper-Plastic Composite Bags: Made with refined white or yellow kraft paper on the outside and a woven plastic cloth on the inside, these bags are laminated together using high temperature and high pressure to melt the plastic particles. They can be lined with PE or aluminum foil, and food-grade linings are available. The lining can also be customized in black or blue to protect the product from light. We have a national industrial product production license for food packaging. These paper-plastic composite bags are equivalent to open-bottom sacks and offer excellent strength, water resistance, and moisture resistance. They are suitable for packaging 5-40 kg of hazardous chemicals, fine chemicals, pharmaceutical chemicals, rubber additives, engineering plastics, chemical raw materials, fine minerals, dyes, pigments, food additives, frozen fruits and vegetables, milk powder, soy protein, and other powdered, granular, flake, and bulk products.
PE, the full name of which is Polyethylene, is the simplest macromolecular organic compound and the most widely used macromolecular material in the world today. It is made by polymerizing ethylene and is divided into high-density polyethylene, medium-density polyethylene, and low-density polyethylene according to different densities. Low-density polyethylene is softer and is mostly polymerized by high pressure; high-density polyethylene has the characteristics of rigidity, hardness, and high mechanical strength and is mostly polymerized by low pressure. High-density polyethylene can be used to make containers and pipes, as well as high-frequency electrical insulation materials for radar and television. Low-density (high-pressure) polyethylene is often used in large quantities. Polyethylene is waxy and has a waxy, smooth feel. When not dyed, low-density polyethylene is transparent, while high-density polyethylene is opaque.
Ton Bags
International Standard Ton Bag Design. Ton bags (also known as bulk bags, flexible containers, ton bags, ton bags, and mother-and-child bags) are flexible transport packaging containers. They are moisture-proof, dust-proof, radiation-resistant, durable, secure, and possess sufficient structural strength. Due to their ease of loading, unloading, and handling, they significantly improve loading and unloading efficiency and have seen rapid growth in recent years. FIBCs are generally made from polyester fibers such as polypropylene and polyethylene. They are widely used for packaging various powdered, granular, and bulk materials, including chemicals, building materials, plastics, and minerals, making them ideal for warehousing and transportation.
Ton bags, also known as flexible freight bags, bulk bags, and ton bags, are medium-sized bulk containers and a type of containerized unit. They can be transported in bulk using a crane or forklift.
They are convenient for transporting large quantities of bulk powdery materials, offering a large capacity, light weight, and ease of loading and unloading. They are a common packaging material. Its characteristics are simple structure, light weight, foldability, small space occupied when empty, and low price.
