Dynamic news：

China's production of sealing machine equipment is growing rapidly. With the change of the market, domestic sealing machinery is also growing. Although few domestic sealing machinery manufacturers can carry out professional research and development, sealing machinery has also made good achievements under continuous efforts, especially beer and beverage filling equipment with high speed, complete sets and automation. With the development of science and technology, developed countries have integrated nuclear energy technology, microelectronics technology, branch technology, biotechnology and system engineering into traditional machines. Machinery manufacturing technology. New materials such as alloy materials, polymer materials, composite materials and inorganic non-metallic materials have also been popularized and applied. The integration, intelligence, networking and mulberry nature of food sealing and packaging machinery will become the mainstream of future development.

 

Faced with the market demand and how to catch up with or even surpass the developed food sealing machinery, and how to increase the pace of independent innovation, and strive to develop a number of products with independent intellectual property rights and level in a short time, it is an urgent task for China's food sealing machinery enterprises that the sealing machine refers to the machinery that seals containers after the packaging containers are filled with products. There are many materials to make packaging containers, such as paper, plastic, glass-ceramics, metal, composite materials, etc. The shape and physical properties of packaging containers are also different, so the sealing forms and sealing devices used are different.

 

(1) Flexible container sealing device

 

Flexible container is a bag container made of flexible materials, such as paper, plastic film, composite film, etc. The sealing of such containers is often combined with bag making and filling.

 

Machine, seldom used independently, because of different materials, its sealing device is also different.

 

(1) Paper bag sealing device. For paper materials, the general use is to brush adhesives at the seals, and then apply mechanical pressure seals.

 

(2) Plastic film bag and compound film bag sealing device. Many expectation materials have good heat sealing property. The expectation bags or composite bags made of this kind of plastics are usually used in

 

The sealing part is heated directly and applied mechanical pressure to make it fuse and seal.

 

(2) Rigid Vessel Sealer

 

Rigid container refers to the container whose shape is not easy to change after the container is formed. Its sealing mostly uses different forms of caps. There are several kinds of sealing machines commonly used.

 

(1) Cap sealing machine. The cap is pre-processed with internal threads, which can be divided into single or multiple threads. If the medicine bottle uses single thread, the canned bottle uses multi-thread, which is sealed by rotating the cap and pressed tightly at the mouth of the container.

 

(2) Rolling sealing machine. This kind of cap is made of aluminium with no threads in advance. It is rolled by rollers to make the cap appear exactly the same thread shape as the cap thread and seal the container. This kind of cover will be broken along the indentation around the skirt when it is unsealed, and can not be restored, so it is also called "anti-theft cover". This machine is mostly used for liquor and beverage.Seal packing.
