Selection principle of double-sided stretching vacuum packaging machine
The stretching vacuum packaging machine is divided into single-sided stretching vacuum packaging machine and continuous double-sided stretching vacuum packaging machine. Its working principle is to use the forming die to heat the film, then use the forming die to punch it into the shape of a container, and put the package into the formed lower film cavity. When it reaches the sealing area, the upper film also forms the shape of a container through a mold, and then vacuum packs. This equipment is called continuous double-sided stretching vacuum packaging machine; However, the molding area does not use molding molds, but only covers. The equipment for vacuum packaging is single-sided stretching machine and vacuum packaging machine; It can be concluded from the working principle that the products packaged by the continuous double-sided stretching vacuum packaging machine have a stronger three-dimensional sense than those packaged by the single-sided stretching vacuum packaging machine, and are more popular with consumers in terms of aesthetics, thus increasing consumers' desire to buy.
For the production enterprises, if they want to put the continuous stretching vacuum packaging machine into production, they need to know what the requirements of the continuous double-sided stretching vacuum packaging machine on the equipment configuration. In other words, what kind of equipment configuration is cost-effective and can create more value for the enterprise?
1. Control system and electrical components: no matter what kind of equipment, the control system is equivalent to the human brain, so the stable and durable configuration should be selected for the control system and electrical components.
2. Vacuum pump: if the performance and stability of the vacuum pump are poor, problems will occur frequently, which will not only affect the shelf life, but also affect the beauty of the product. If maintenance is required, it will definitely affect the manufacturer's ability to work.
3. Whether the equipment has fault alarm device and protective device: since the continuous double-sided stretching vacuum packaging machine does not need to order bags and is divided into single products, whether the equipment is equipped with protective device and fault alarm device is also a factor for enterprises to choose equipment.
4. Equipment appearance: For double-sided tensile vacuum packaging machine, the equipment frame adopts the appearance of 20mm thick aluminum alloy and 304 stainless steel plate. The first reason is that the equipment is sturdy and durable, and the second is to improve the accuracy of the equipment, reduce the deviation probability of the upper and lower membranes of the equipment, and improve the product qualification rate.
In the scorching sun, Shandong Bofa Packaging Machinery Co., Ltd. delivers stretch film vacuum packaging machine for leisure food.
With the arrival of the automation era, many enterprises have begun to transform. The original manual operation has been gradually replaced by machines. Automated equipment can not only improve the work productivity, but also free the labor from the heavy work.
For a long time, food packaging is mainly based on traditional technology. Such trivial and heavy repetitive manual labor is difficult to complete large-scale production. The working environment is poor, the labor intensity of workers is high, the yield of good products is low, and the stability of product quality is poor.
How much do you know about the types of automatic stretch film packaging machines? Let's have a look. Automatic stretch film packaging machine is a universal packaging machine, and different types are also calculated according to the working capacity of the product.
The stretching vacuum packaging machine is divided into single-sided stretching vacuum packaging machine and continuous double-sided stretching vacuum packaging machine. Its working principle is to use the forming die to heat the film, then use the forming die to punch it into the shape of a container, and put the package into the formed lower film cavity.
