Vacuum packaging machines can be divided into desktop vacuum packaging machines, single -room vacuum packaging machines, dual -room vacuum packaging machines, vertical vacuum packaging machines, home vacuum packaging machines, outer pump vacuum packaging machines and other vacuum packaging machines.Lets introduce it below!
Vacuum packaging machine workflow
After the packaging bag is pumped into a low vacuum, it is automatically sealed immediately. Due to the high vacuum in the bag, there are very few residual air. Inhibit the reproduction of microorganisms such as bacteria, avoiding oxidation, mold and corruption of items, and at the same time, for some soft itemsAfter the fully automatic vacuum packaging machine is packaged, the packaging volume can be reduced, which is convenient for transportation and storage.The principle of desktop vacuum packaging is based on plastic composite film or plastic aluminum foil composite film as the packaging material.Rare metals and other vacuum packaging or vacuum inflatable packaging.
Principles of the selection of vacuum packaging machines
There are many varieties of vacuum packaging machines, and the following factors should be focused on when choosing.Packaging speed.Due to the consideration of improving production efficiency, a double -room or multi -room vacuum packaging machine can be selected to improve the progress of the entire production.Whether the packaging items need to be filled with other protective gases.You can choose a multifunctional vacuum packaging machine with an inflatable device.Requirements for vacuum of packaging items.If the packaging items need to be preserved under the condition of high vacuum, you need to choose an internal pump vacuum packaging machine.The component status of the packaging items on the vacuum packaging machine.When buying, if the packaging solid, particles, etc. are relatively dry and non -corrosive materials, the aluminum alloy material can be used, and the packaging with soup, the material with high salt and acid components, can be selected from stainless steel or aluminum -magnesium alloy material material material.EssenceThe sealing ring is generally used in silicon rubber, black rubber, and a few low -grade products use foam rubber. Silicon rubber is resistant to high temperature, corrosion resistance, good sealing, long service life, poor sealing rubber sealing, easy loss, and short service life.
How to buy a vacuum plastic sealing machine
1. Vacuum plastic sealing materials are used. Generally, the machines produced by regular manufacturers are made of stainless steel (generally stainless steel must be used in packaging foods).Considering the cost of saving costs, iron can be considered.In the comparison of iron and stainless steel, the use time for stainless steel is much longer than iron and safer.Vacuum packaging plastic machine is best for 304 stainless steel.Please consult what material the machine is when buying a machine.
2. The quality of various electronics and various accessories in the machine. Generally, regular manufacturers generally use relatively stable accessories. When you buy the machine, you must pay attention.Regular vacuum packaging plastic machine manufacturers generally send a set of free or multi -sets of damaged accessories for free.
3. The power and quality of the vacuum pump of the vacuum plastic machine are also very important. Generally, when you buy a machine, you will also consult the manufacturer of the manufacturer to maintain the vacuum pump in many machine parts.Need to maintain regularly.
4. While you buy a machine, you must figure out your packaging requirements (such as size, weight) and the packaging speed of the machine. The time of the general machine sealing gas is adjustable.You must consult the staff when you buy a machine.
5. Vacuum plastic sealing machines are divided into two types: extraction and internal pumping type. Both models are used in effect.The external vacuum packaging machine is generally suitable for items (such as electronic parts, etc.) that are not highly required by the vacuum.The internal vacuum packaging machine is generally suitable for items (such as food, etc.) with higher vacuum requirements (such as food, etc.).
