Hot pressing:
Hot press bonding technology mainly uses electric heating devices to heat products through external heating plates, such as PE, PET or PVC materials. The technique, similar to how an electric oven works, uses heat to soften the material and then sticks two or more pieces together with the help of pressure. Hot pressing is often used to make some packaging products that require high strength and stability, such as battery packaging and lip balm packaging. Its material selection is wide, PET material environmental protection and high transparency, but high quality requirements for color cards; PVC material is flame retardant and cold resistant, but some countries may consider it not environmentally friendly.
High frequency fit:
The high frequency laminating technology uses the principle of high frequency electromagnetic field to achieve fast, efficient and environmentally friendly laminating of plastic materials through high frequency heating and precision pressing technology. The technology is similar to how microwave ovens work, but much more precise and efficient. The high frequency signal acts on the surface of the plastic material, causing the internal molecules to move violently and generate heat, quickly reaching a molten state, and then forming a tight packaging structure through mold pressing. High frequency laminating is widely used in stationery, food, medicine, electronics and other industries, especially suitable for PVC and other plastic materials packaging. The heating speed is fast, the production efficiency is high, and there is no need to use harmful substances such as chemical solvents, which meets the requirements of environmental protection.
In SUMMARY:
In general, hot press bonding and high frequency bonding have their advantages and disadvantages in blister packaging. Hot pressing technology material selection is wide, suitable for a variety of materials. The high frequency laminating technology has fast heating speed, high production efficiency and is more in line with environmental requirements. In the selection, it is necessary to comprehensively consider the specific needs of the product, material characteristics and production efficiency.
