Welding of medicine bags: A core link that cannot be ignored in the field of pharmaceutical packaging

Welding of medicine bags is a core link that cannot be ignored in the field of pharmaceutical packaging. Through technologies such as high-frequency welding and ultrasonic welding, it ensures the sealing, safety and production efficiency of medicine bags, playing a key role in protecting the quality of drugs, meeting regulatory requirements, improving production efficiency and adapting to diverse demands. The following is a detailed analysis: First, the significance of welding medicine bags in pharmaceutical packaging

1. Protecting the quality of medicines: The medicine bag welding technology effectively prevents medicines from being contaminated or leaked by the outside during storage and transportation by forming a strong weld seam, ensuring the safety and efficacy of the medicines.

2. Meet regulatory requirements: Pharmaceutical packaging must comply with strict regulatory standards, such as sealing and sterility. The welding technology for medicine bags can meet these requirements and ensure the compliance of medicine packaging.

3. Enhance production efficiency: High-frequency welding, ultrasonic welding and other technologies are characterized by high efficiency and precision, which can significantly increase the production efficiency of medicine bags and reduce production costs.

4. Adapt to diverse demands: With the continuous development of the pharmaceutical industry, the forms of drug packaging are becoming increasingly diverse. The welding technology for medicine bags can adapt to the welding requirements of medicine bags of different shapes, sizes and materials, meeting the diverse demands of the market.

Ii. Specific Applications of Medicine Bag Welding Technology

High-frequency welding technology

High-frequency welding technology is widely used in the production of medical packaging such as large-volume infusion bags and emergency medicine bags. The heat generated by high-frequency vibration causes the molecular polarization and friction of plastic materials to generate heat and fuse, forming a strong weld seam.
Advantages: High-frequency welding technology features high efficiency, precision and strong sealing performance.

2. Ultrasonic welding technology

Application scenario: Ultrasonic welding technology is suitable for the production of pharmaceutical packaging such as four-sided sealed bags (small bags). The heat generated by ultrasonic vibration melts and bonds plastic materials, forming seamless connections.
Advantages: Ultrasonic welding technology has almost no thermal effect on fillers and can perfectly protect the original properties and quality of medical supplies. Meanwhile, this technology can also significantly reduce the problem of bag leakage and improve the product qualification rate.
