With the development of the times and the advancement of technology, packaging machinery is playing an increasingly important role in the packaging field. vacuum packaging machines is to extract all the air in the packaging container and seal it to maintain the height of the bag. In a compressed state, scarce air is equivalent to low oxygen effect, so that microorganisms have no living conditions to achieve the purpose of fresh fruit and no disease. The current applications include vacuum packaging in plastic bags, aluminum foil packaging, glassware, plastics and their composite materials. For packaging, etc., packaging materials can be selected according to the types of items. Since the fruits are fresh and live food, they are still undergoing respiration, and high levels of hypoxia can cause physiological diseases. Therefore, the use of vacuum packaging for fruits is less.
1. Food vacuum packaging machines: At present, most of these packaging machines in China are driven by servo motors. The more advanced ones are equipped with color screen touches for easy operation. At the same time, because these products have higher requirements for preservation, they should be used before vacuum packaging. The temperature should be controlled, and the equipment has its own cooling system; sometimes it is equipped with a gas filling system on the basis of vacuuming, which can be filled with inert gas such as nitrogen to achieve a better quality assurance effect.
2. Medical vacuum packaging machines: This is an exquisite aseptic packaging machine. It adopts a special vacuum system and exhaust device, which is especially suitable for purification in electronics, food, medicine and other industries. It is used in high places; at the same time, the form of vacuuming is also more conducive to the storage of such products for a longer time, without contact with the air, completely eliminating secondary pollution; at the same time, this type of equipment can also be applied to food packaging with aseptic requirements to achieve Good results.
3. Electronic product vacuum packaging machines: This is a typical electronic product packaging machine, suitable for electronic products, such as semiconductors, crystals, PCBs, and can prevent moisture, oxidation and discoloration of internal metal processing parts. Vacuum packaging reduces the packaging volume and saves logistics costs. At the same time, it can also vacuumize large and fluffy objects such as fabrics and woolen textiles. In addition, this type of machine can usually make the finished product have impact resistance characteristics. So as to protect the precision instruments.
