The structural design points of container lining bags mainly include the following aspects:
1. Material selection
- Main material: PE/PP woven fabric is usually used; its strength and durability can meet the needs of container transportation. Depending on the characteristics of the goods and transportation requirements, woven fabrics of different thicknesses and specifications can also be selected.
- Sealing materials: For goods that need to be moisture-proof and leak-proof, PE film or coating materials with good sealing properties should be selected. These materials can effectively prevent moisture and air from entering the lining bag, thus protecting the quality of the goods.
2. Structural layout
- Feeding port design: Depending on the loading and unloading method of the goods, you can choose a cylindrical or rectangular feeding port. The cylindrical feed opening is suitable for loading with a blower, while the rectangular feed opening is suitable for loading with a conveyor belt. The feed opening should be designed to be wide enough to facilitate quick and smooth loading of goods.
- Design of discharge openings: The location and number of discharge openings should be determined according to the characteristics of the goods and transportation needs. Usually, the discharge port should be designed at the bottom or side of the container to facilitate the unloading of goods. At the same time, the discharge port should be installed firmly and tightly to prevent the goods from leaking during transportation.
- Baffles and support structures: In order to maintain the stability and shape of the lining bag in the container, baffles or support structures can be designed. These structures can effectively prevent the lining bag from being deformed or damaged due to the movement of goods during transportation.
3. Functional design
- Inflatable pipeline design: For some goods with poor fluidity and high viscosity, an inflation pipeline can be designed at the bottom of the lining bag. By inflating the pipe, airflow can be generated to act on the material, thereby assisting in unloading. This design can greatly improve unloading efficiency and reduce manual labor intensity.
- Suspension and fixation design: In order to ensure the stability and safety of the lining bag in the container, the suspension and fixation structure can be designed. These structures can securely fix the lining bags to iron rings or hooks inside the container, preventing them from being displaced or damaged due to bumps or collisions during transportation.
4. Other considerations
- Environmental adaptability: The lining bag should be able to adapt to transportation needs under different environmental conditions. For example, in high or low temperature environments, the material of the lining bag should be able to maintain stable performance and not deform or crack due to temperature changes.
- Environmental protection: With the increasing awareness of environmental protection, the environmental protection of lining bags has also become an important consideration. Recyclable or degradable materials should be chosen to make lining bags to reduce environmental impact.
