The manual sealing machine is mainly used for the aluminum foil sealing operation of non-metallic packaging containers such as beverages, medicines, and lubricants. The small eddy current generated instantaneously promotes the high-speed melting of the aluminum foil and achieves the purpose of sealing and bonding. Some of the emerging manual sealing machines are an indispensable and important part of the aluminum foil sealing operation. Now, a brief summary of which sealing materials are more suitable for manual sealing machines to be used together:
1. Polypropylene (PP)
The hot-melt sealing principle of the manual sealing machine mainly adopts the principle of electromagnetic induction heating, which uses high-frequency current to generate the corresponding magnetic field through the inductor coil. When the generated magnetic force passes through the sealing aluminum foil material, a large number of small eddy currents are instantly generated. These small eddy currents can quickly cause the polypropylene (PP) material to melt on the seal of the sealing material, so that the polypropylene (PP) can be quickly sealed.
2. Polyester (PET)
The manual sealing machine adopts the microcomputer control mode and the power is adjustable. Polyester (PET) is a linear thermoplastic resin and an engineering plastic with a high application rate. Some seasonings, cosmetics and medicines are all sealed with this material, as long as the manual sealing machine is used to melt and compound In polyester (PET) sol, then the purpose of fast sealing can be achieved.
3. Polystyrene (PS)
There are many types of materials suitable for melting and sealing by manual sealing machines, and polystyrene (PS) is also one of the more commonly used materials. Disposable foam lunch boxes, disposable containers, and daily decorations are all made of this material. At this time, only the efficient sealing function of the manual sealing machine can be used to achieve the purpose of fast sealing.
The innovation and development of manual sealing machines have promoted the rapid development of beverage, pharmaceutical and lubricant industries. This has also prompted the increase in the number of people who have paid attention to and inquired about the manual sealer. According to a large number of market statistics, manual sealers are suitable for use with polypropylene (PP), polyester (PET) and polystyrene (PS) materials. It is also suitable for use with other materials such as ABS and glass.
