As a common equipment in packaging machinery, sealing machine is used to seal the packaging container in order to seal the product, maintain the product quality and avoid product loss. This sealing form refers to the machinery for sealing the container after it is filled with products. There are many materials for making packaging containers, such as paper, plastic, glass, ceramics, metal, composite materials, etc., and the shape and physical properties of packaging containers are also different. Therefore, the sealing forms and sealing devices used are also different.
Generally according to the mechanical properties of packaging materials, it can be divided into the following two categories: flexible container sealing device. Flexible container is a bag container made of flexible materials, such as paper, plastic film and composite film. The sealing device of this kind of container is usually combined with bag making and filling, and rarely used independently. Due to different materials, the sealing devices are different. Rigid container sealing machine. The rigid container refers to the container whose shape is not easy to change after the container is formed. The sealing of the rigid container is usually with different forms of covers, which are commonly used as follows.
Generally speaking, there are two forms of sealing machine in sealing and packaging. Well known, screw cap. The inner thread of the cover is machined in advance, and the thread can be divided into single head or multiple head. For example, single head thread is used for medicine bottle and multi head thread is used for jar head bottle. The machine is to rotate the cover and press it on the mouth of the container. Second, rolling. This kind of cover is mostly made of aluminum, and there is no thread in advance. Instead, the aluminum cover is rolled by roller to make it appear the thread with the same shape as the screw thread at the bottle mouth, so as to seal the container. When the lid is unsealed, it will be broken off along the indentation around the skirt and cannot be restored, so it is also called "anti-theft cover". This machine is mainly used for sealing and packaging of liquor and beverage.
