As a type of commonly used equipment in a vacuum packaging machine, the sealing machine is a machine that must seal the packaging container after the product has been loaded into the packaging container to seal and preserve the product, maintain product quality, and avoid product loss , This form of sealing refers to the packaging container with products, the container for the sealing of machines. The material that makes up the packaging container is very much like paper, plastic, glass, ceramic and porcelain, metal, composite, and the configuration of the packaging container, and the physical performance also varies according to the shape in which USES and sealing device differ ,
Depending on the mechanical properties of the plastic injection molding machine, it can be divided into the following two categories: flexible container sealing device. The flexible container is a type of bag container made of flexible materials such as paper, plastic film and laminated film. The sealing device of this type of container is often combined with a bag making and filling machine that is seldom used independently. Due to the different materials, the sealing device is also different. Ridiger container sealer. Rider container refers to the container whose shape is not easy to change after molding the container, its seal is versatile and the cover of different shape that is commonly used , the following have a few types.
In general, the sealing machine has two performance forms in the manual sealing machine and in the package. Well-known screw cap. This type of lid is pre-processed into a female thread that can be divided into single-head or multi-head. For example, a single-head thread is more commonly used in medicine bottles, and multiple threads are more commonly used in cans. The machine turns the lid and pushes it against the mouth of the container. Second, roller marks. The cap is made of aluminum and has no thread before. The cap is rolled by a roller so that it has the same thread form as the bottle cap to close the container. This type of cover is broken along the depression around the edge if it is not closed and can not be restored. Therefore, it is also called "theft protection". This machine is mainly used for sealing and packaging high quality alcoholic beverages.
