With the rapid development of the modern logistics industry, logistics packaging has received more and more attention. As a plastic bag for loading bulk materials, ton bags are widely used in logistics transportation in industries such as minerals, fertilizers, and grain. Ton bags have a simple and practical structure, and also have many different advantages. This article will introduce the structure and characteristics of ton bags in detail. Structure and characteristics of ton bags
1. Bag body
The main part of the ton bag is generally made of high-strength materials such as polypropylene and is used to load materials. The shape of the bag body can be square, rectangular or cylindrical, etc., and can also be customized according to needs. The bag body of the ton bag is generally made of a seamless one-time molding process, which has a high load-bearing capacity and wear resistance.
2. Top
The top of the ton bag usually adopts a hanging ear design for easy lifting and hanging. The hanging ear is generally made of folded bag material, and some ton bags are reinforced with materials such as wire rope or plastic rope.
3. Top
The top of the ton bag is usually a circular opening, through which the material can be loaded into the bag. After filling with materials, the upper mouth will be sewn or sealed to ensure that the materials will not overflow from the bag mouth.
4.the lower mouth
The lower mouth of the ton bag is usually also a circular opening, which is used to pour the materials out of the bag. The design of the lower mouth can be adopted in different ways, such as heat sealing, manual sewing or automatic sewing.
5.the bottom
The bottom of the ton bag is generally designed with a flat bottom or a round bottom. The flat bottom is usually cut by cutting the four corners of the bag body and then sewing it to form a flat bottom; the round bottom is to add a round pad in the center of the bag body to make the bag stand upright. Moisture-proof pads or anti-slip pads can also be added to the bottom to enhance the stability and moisture-proof performance of the bag.
6.The valve mouth
The valve mouth of the ton bag is usually located at the bottom or side of the bag body, and can be filled or unloaded through the valve mouth. The valve mouth is generally designed with a plug or zipper to ensure that the material will not overflow or be contaminated.
7. Corner bands
To enhance the bag's load-bearing capacity and wear resistance, ton bags are usually equipped with corner bands at the corners. Corner bands can be made of a variety of different materials, such as plastic, canvas or cowhide, to increase the bag's strength and durability.
8. Liner
A liner can be added to the inside of the ton bag to improve the bag's sealing and moisture-proof properties. The liner is generally made of materials such as polyethylene or polyester, and can be fixed inside the bag by heat sealing or stitching.
9. Reinforcement
The reinforcement of the ton bag can increase the strength and stability of the bag to prevent the bag from breaking or deforming during transportation. The reinforcement is generally made of materials such as polypropylene tape or wire rope, and can be fixed at the four corners or sides of the bag.
10. Anti-static
For some flammable, explosive or static-sensitive materials, ton bags can also adopt anti-static design to prevent fire or explosion caused by static electricity. Anti-static ton bags are generally made of materials such as conductive polypropylene or conductive polyimide.
In summary, the structure and design of ton bags can be adjusted and optimized according to different materials, transportation methods and usage requirements to ensure the safety and convenience of material transportation and storage. Its wide application has promoted the improvement of efficiency and quality of packaging and transportation of bulk materials. It has contributed to the efficient, convenient and environmentally friendly development of the logistics industry.
