China - After the product entered into the packaging container, the sealing process is necessary for maintain product quality and avoid product loss. This operating process should be accomplished by the special sealing machine. In fact, there are many different materials which could be sued for producing the packaging container such as paper, plastics, glass, ceramics, metal, composites and others. Furthermore, the morphology and the physical properties of the packaging container are also not the same. In that case, the sealing methods and related equipments also have some difference.
Today, the engineer from famous sealing equipment www.china-sealer.com manufacturer WENZHOU CHUNLAI PACKING MACHINERY will teach people mainly category of their excellent products.
Generally, the sealing equipment could be divided into following two categories based on the mechanical properties of packaging materials.
The first kind of sealing machine could be used for the sealing process of the flexible container made of the flexible materials such as paper, plastic films, laminated films and others. The sealing device for these materials packages should be the joint machine with the bag making and filling machine, which is rarely used independently. Due to the different materials, the sealing device in this category is also not the same.
Paper Bag packing machine
For paper-like material, it will be commonly brushed the adhesive and then subjected by the pressure from the mechanical parts.
Composite Film Bags and Plastic Film Bag Sealing Devices
Many plastic materials have good heating sealing properties. For the bags and packages sealing machine which made of these materials, it could be directly subjected to heat and mechanical pressure on the seal parts.
The second main category of the sealing machine from china-sealer.com should be the so called rigid container sealing device. The rigid containers could not be easy to be changed the shape after the molding process. The sealing objects for these containers are normally the metal caps
Cap Sealing Machine
For the caps, employers should firstly pre-process the internally screw thread which could be divided into single or multiple types. For example, the medicine bottle always use the single thread and the commonly cans bottles usually apply the multi-threaded caps. The sealing process of this cap is always through the rotating process and then the caps would be pressed to the container mouth.
After here, the main information about the categories about the commonly used sealing machine in the packaging industry has already been shown. However, with the development of the related market demand and technology, it will be created many new type of sealing devices in every year.
