Industrial Garbage Bags undertake the important task of waste collection and transportation in various industrial scenarios. Their sealing design plays a key role in preventing odor and harmful substances from leaking.
First of all, there are many common ways to seal Industrial Garbage Bags. Drawstring sealing is a common one. By setting a drawstring at the bag mouth, the bag mouth can be shrunk and closed after tightening. This method is relatively easy to operate, but the sealing degree is limited, and the barrier effect for odor and fine particles is general. Heat-sealing sealing uses high temperature to melt and bond the plastic at the bag mouth, which can form a relatively tight seal and effectively prevent odor and harmful substances from escaping. However, special heat-sealing equipment is required. It is suitable for large-scale industrial production and garbage bags with high sealing requirements. There is also a self-sealing strip seal, which is similar to the design of food preservation bags. The self-sealing strip at the bag mouth can be pressed and bonded to provide a certain sealing guarantee, which is convenient to use and low cost.
Secondly, the principle of sealing design for odor and harmful substance leakage prevention and control is to reduce the diffusion channel of gas and substance. When the garbage bag is well sealed, odor molecules and harmful particles are confined in the bag. For example, taking the waste garbage bags containing volatile organic compounds (VOCs) produced by the chemical industry as an example, good sealing can prevent VOCs from spreading to the surrounding environment, avoiding air pollution and harm to human health. For industrial waste containing harmful substances such as heavy metal dust, sealed garbage bags can prevent dust leakage and avoid secondary pollution during transportation and storage.
Furthermore, in order to enhance the sealing effect and prevention and control capabilities, Industrial Garbage Bags also have corresponding designs in materials and structures. In terms of materials, plastic materials with low air permeability can be selected, such as composite materials of high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) to reduce odor and harmful gas penetration. In terms of structure, the number of folding layers of the bag mouth can be increased or a special sealing lip can be designed to improve the tightness of the seal. In addition, some garbage bags will also add an adsorption layer, such as an activated carbon adsorption layer, which can adsorb some odor molecules and further reduce the risk of odor leakage.
Finally, in actual use, correct operation and maintenance should not be ignored. After filling industrial garbage, users should carefully follow the sealing design requirements to ensure a tight seal. For drawstring seals, tighten the drawstrings, ensure the heat seal quality for heat seals, and fully bond the self-sealing strips for self-sealing strips. At the same time, avoid sharp objects puncturing or excessive squeezing of garbage bags during transportation and storage to avoid damaging the sealing structure and causing leakage. Regularly check the sealing status of garbage bags and replace garbage bags that are at risk of damage in a timely manner to fully guarantee the effectiveness of Industrial Garbage Bags in preventing and controlling odor and harmful substance leaks, and maintain the safety and hygiene of the industrial production environment and the surrounding ecological environment.
