What are the precautions when using plastic bag packaging

Material selection and applicability
In the field of plastic bag packaging, the choice of materials is crucial. Common plastic materials include low-density polyethylene (LDPE), high-density polyethylene (HDPE) and polypropylene (PP). These materials have different physical and chemical properties, so in practical applications, they need to be scientifically selected according to specific usage scenarios and needs. For example, plastic bags for food packaging must meet the standards of non-toxicity and odorlessness and meet relevant food safety regulations; while the packaging of medical supplies requires sterility and anti-leakage performance. The plastic bag packaging provided by Zhongya Electric uses high-quality raw materials to ensure that the products meet industry standards and regulatory requirements and ensure the safety of customers.

Size and shape design
The size and shape design of plastic bag packaging should be accurately planned according to the characteristics of the packaged items. Oversized packaging may cause the items to shift during transportation and storage, while undersized packaging may not effectively protect the items and increase the risk of damage. Therefore, reasonable size and shape design not only improves the stability of the packaging, but also enhances its aesthetics. Zhongya Electric has a professional design team that can provide customized size and shape design services according to the specific needs of customers, ensuring that each plastic bag packaging can perfectly fit the packaged items and maximize the use effect.

Sealing and moisture-proof performance
Sealing and moisture-proof performance are key indicators of the effectiveness of plastic bag packaging. During the packaging process, it is crucial to ensure that the sealing width at the seal is sufficient and the seal is tight and leak-free. Especially for items that need to be moisture-proof, it is particularly important to choose plastic bag packaging with good moisture-proof performance. Zhongya Electric uses advanced sealing technology to ensure that the seal of each plastic bag has excellent sealing and moisture-proof performance. In addition, the company also provides auxiliary materials such as moisture-proof agents and desiccants to meet customers' special requirements for moisture-proof performance and ensure the stability and safety of products in various environments.

Printing and labeling
Printing and labeling of plastic bag packaging are crucial for product identification, promotion and compliance. During the printing process, Zhongya Electric strictly follows environmental protection requirements, selects harmless inks and advanced printing processes to avoid potential harm to the environment and human body. The design of the label content must ensure clarity, accuracy and easy identification, including product name, production date, shelf life and manufacturer information. With advanced printing equipment and technology, Zhongya Electric can provide customers with high-quality printing and labeling services to help customers enhance their brand image.
