What are the common types of sealing machine

Sealing machine is widely used in modern packaging to ensure the long-term quality of the product, the main outlet of the packaging materials are plastic packaging, paper packaging, metal packaging. Because of the different shapes of packaging containers, different materials, and the variety of foods inside the packaging, there are many types of sealing machines. What are the common types of capping machines?
Paper bag packaging sealing machine, paper bag packaging is relatively easy to fold, sealing is relatively simple, people in daily life often glue, tape and other adhesive material slaughtered to seal the place, hand pressed tightly after drying. The principle of the sealing machine for paper bags is the same as above, except that the place where the external force of the machine presses the glue is used instead of manual pressing.
Soft plastic sealing machine, which mainly uses the principle of resolidification after melting the packaging material, heating slightly at the place where the sealing is needed, softening the thin plastic packaging material, and then pressing it to cool Coagulate together. This method is also widely used in the packaging of beverage bags such as packaging of composite film bags, tea cups, soya milk cups, and fruit juice cups.
Screw cap sealing machine, this sealing machine is often used to package the complex sealing of bottles and cans, such as the common medicine bottle, fruit canned bottle, his principle is slightly more complex than the above two, need to be processed in the cap in advance Threads, the machine rotates tightly when closing. A more sophisticated can of food can also be packaged using a can lid and a bottle body crimped together after crimping.
Rolling sealer, the appearance of the screw thread is similar to the sealing method and the biggest difference between screw cap sealing machine is whether the thread is pressed in advance, rolling seal in the packaging according to the thread of the bottle, this After the pressure is released, it cannot be restored.
Other common types of capping machines include roller sealing machines that roll caps inwards, starters, electromagnetic induction cappers, and convenient hand-held cappers.

Thick Film Electric Heating Circuit is made on stainless steel plate and insulated by insulation layers. It can heat stainless steel plate evenly and temperature ramp up above 80℃/S. Compared with other Electric Heating Element, Thick Film Heating Plate is advanced in larger heating area (Heating Circuit uniform covered Heating Plate), higher power density, faster Temperature Response (above 80℃/S), Longer Life Span (above 10,000 hours), Lower Thermal Inertia and better Heat Transfer Efficiency(≥98%). Any size and power can be customized.
