Description:Ton bags must ensure the canvas strength and enhance the tensile strength of the film yarn. The film yarn strength should reach above 0.4N/tex, with elongation between 15% to 30%. During the practical processing, the amount of the masterbatch should be strictly controlled, usually around 2%. Over-addition of the masterbatch or the addition of recycled material will lead to a decrease in canvas strength. Therefore, a strict quality control should be maintained on the raw materials, and the film yarn should be selected from manufacturers that produce according to the national standards with the melt index.
Chemical ton bags material:
Tonnage bags are made primarily from polypropylene, mixed with a small amount of stabilizing additives, which is then melted and extruded into plastic film through an extruder. The film is cut into strips, stretched, and thermally set to form high-strength, low-elongation PP raw yarn. This yarn is then woven and coated to create the base fabric for plastic burlap, which is sewn together with straps and other accessories to form the tonnage bag. The weaving material thickness of the tonnage bag is 170-200 grams per square meter. Tonnage bags are medium-sized bulk containers and a type of container unit, which, when paired with cranes or forklifts, enable containerized unit transportation. They are convenient for transporting large quantities of loose powdered materials, featuring large volume, light weight, and ease of loading and unloading. They are one of the common packaging materials. Their characteristics include simple structure, light weight, foldability, minimal space when empty, and low cost.

High precision, large packaging capacity, sealed, environmentally friendly, high level of automation, large production capacity, wide application range, easy operation, and convenient handling. Features include automatic weight stripping, automatic zeroing, and high sensitivity, making it widely used in various enterprises.
Tonnage bags for chemical fine powder packaging offer advantages over manual packaging:
1. The chemical fine powder ton bag packaging scale features stable structure and smooth operation.
2. Various cutting methods are available, fundamentally eliminating production issues such as material jams and blockages caused by excessively large angles of repose.
3. Mechanical materials are available for selection to meet the chemical reaction requirements of certain materials.
4. Custom-grade equipment, available for customization to meet various customer requirements.
5. Fully enclosed equipment, preventing dust overflow and other pollution issues, and significantly reducing product hazards.
6. Fully automatic products, continuously saving labor costs.
7. Scientifically and reasonably designed, with options for various conveying equipment (pipe chain hoists, screw conveyors, belt conveyors).

Chemical ton bags usage precautions:
Do not stand underneath the bulk bags during lifting operations.
2. Please hang the hook on the designated area of the strap or rope, avoid slanting吊 or single-side吊 or diagonal tensioning of the container bag.
3. Do not rub, snag, or collide with other items while handling the container bags.
Do not pull the straps outward in a reverse direction.
5. When using a forklift with bulk bags, please do not let the forks come into contact or puncture the bag to prevent tearing.
6. During handling in the workshop, try to use pallets instead of lifting the woven bags with hooks, which can cause swinging and movement during transportation.
7. Keep the bags standing upright during loading, unloading, and stacking.
8. Do not stand the container bags upright.
9. Do not drag the container bags on the ground or concrete.
10. When storage outdoors is unavoidable, the container bags should be placed on shelves and must be securely covered with opaque tarpaulins.
11. After use, wrap the container bag with paper or opaque tarpaulin and store it in a well-ventilated area.
