Vacuum packaging technology for food vacuum packaging machines was applied in the early 1990s. With the promotion of small packaging and the development of supermarkets, its application range is getting wider and wider. Some of them will gradually replace hard packaging, and the prospects are very bright.
So, when we buy a food vacuum packaging machine, how should we choose? As there are many types of vacuum packaging machines, on this basis, the selection and purchasing points of food vacuum packaging machines are introduced.
1. Consider packaging speed. In order to improve production efficiency, you can choose a double-chamber or multi-chamber food vacuum packaging machine to improve the progress of the entire production.
2. Considering whether the packaging items need to be filled with other protective gases, a multifunctional food vacuum packaging machine with an inflatable device can be selected.
3. Taking into account the vacuum requirements of the packaged items, if the packaged items need to maintain a good condition under high vacuum conditions, a cavity vacuum packaging machine should be selected.
4. Consider the requirements of the vacuum packaging machine on the composition of the packaged items. When selecting and purchasing a food vacuum packaging machine, the packaging solids and granules are dry and non-corrosive materials. Aluminum alloy materials can be selected, and the packaging with soup, salt, and acidic materials can be stainless steel or aluminum alloy materials.
In addition, the key points of the food vacuum packaging machine include checking whether its sealing ring is made of high-quality silicone rubber such as black rubber and foamed rubber, because high-quality silicone rubber seals have the characteristics of high temperature resistance, corrosion resistance, good sealability, and long service life , And foam rubber has poor sealing, easy to fall off, and short service life.
