Double blister thermoforming packaging machine high-frequency heat sealing machine PVC double blister high-frequency packaging machine

Double blister thermoforming packaging machines and high-frequency heat sealing machines, or PVC double blister high-frequency packaging machines, are commonly used equipment in the plastic packaging industry. They share certain similarities in function and application but also have some differences. The following is a detailed introduction to these two types of equipment:

I. Double Blister Thermoforming Packaging Machine and High-Frequency Heat Sealing Machine (PVC Double Blister High-Frequency Packaging Machine)

Working Principle: Primarily utilizes a high-frequency electromagnetic field to generate frictional heat between the molecules of plastic materials (such as PVC, PET, etc.), enabling fast and efficient welding.

During the sealing process, the equipment uses high-frequency heating and mechanical pressure to tightly seal pre-made plastic blisters with materials like paper cards.

Features:

High Efficiency and Speed: Rapid heating and short sealing time significantly improve packaging efficiency.

Easy Operation: High automation level, simple and easy-to-learn operation, reducing labor costs.

Aesthetically Pleasing Seal: Smooth and attractive sealing, free of burrs and bubbles, enhancing product quality.

Environmentally Friendly and Energy-Saving: No need for adhesives or other auxiliary materials, reducing pollution and meeting environmental requirements.

Applications: Widely used in industries such as toys, electronics, hardware, food, cosmetics, and pharmaceuticals, meeting the packaging needs of various products.

II. Double Blister Thermoforming Packaging Machine and High-Frequency Heat Sealing Machine (PVC Double Blister High-Frequency Packaging Machine)

Working Principle: The blister high-frequency welding and edge sealing machine also uses a high-frequency electromagnetic field for heating but focuses more on welding and sealing the edges of blisters (i.e., plastic packaging shells).

During the welding process, the equipment precisely controls the intensity and distribution of the high-frequency electromagnetic field to rapidly heat and weld the edge materials of the blister, forming a strong seal.

Features:

Precise Welding: Capable of accurately controlling welding position and strength, ensuring a secure and aesthetically pleasing seal.

High Adaptability: Suitable for welding blisters made of various plastic materials, including PVC, PET, etc.

High Automation Level: Typically equipped with a PLC control system for fully automated operation, reducing manual intervention.

Easy Maintenance: Compact structure and rational design facilitate daily maintenance and upkeep.

Applications:

The blister high-frequency welding and edge sealing machine is primarily used for blister packaging products in the plastic packaging industry, such as pharmaceuticals, health products, and cosmetics. By welding and sealing the edges, it ensures the integrity and sealing of blister packaging, improving product safety and shelf life.
