Vacuum packaging technology originated in the 1940s. 1950's polyester and polyethylene plastic films were successfully used in vacuum packaging, and since then vacuum packaging has developed rapidly. With the promotion of small packaging and the development of supermarkets, the application range of vacuum packaging machines is becoming more and more extensive, and some will gradually replace hard packaging, and the prospects are very promising.
What are the areas of application of vacuum packaging machines?
What should be considered after using the vacuum packaging machine?
What is the selection principle of vacuum packaging machine?
The vacuum packaging machine uses plastic or plastic aluminum foil as packaging material, vacuum liquid, solid, powdered and pasty food, cereals, fruit, cucumbers, canned fruit, chemicals, medical materials, electronic components, precision instruments, rare metals, etc. Packaging, vacuum packed items can prevent oxidation, mold, moth eating, rot, moisture, and extend shelf life. It is especially suitable for tea, food, medicine, shops, research institutions and other industries. It has the advantages of beautiful appearance, compact structure, high efficiency, easy operation and convenient to move seat wheel at the bottom.
1. When the vacuum packing machine is exhausted or inflated, the indicator lamp will go out and the heat seal indicator lamp will light up, that is, the sealing process is entered. On the plate there are adjustment knobs for heat sealing time and temperature to adjust them to different material thicknesses. If the rotation is small, the rotation range should be small to prevent the heat seal temperature from suddenly rising and the heat seal parts from burning out.
2. When the vacuum packing machine reaches the set heat sealing time, the heat sealing indicator goes out and the heat sealing is finished, that is, the vacuum chamber enters the atmosphere through the solenoid valve until the lid is automatically lifted. and the vacuum inflatable packaging process is over. Proceed to the next winding cycle.
There are many types of vacuum packaging machines, and the following factors should be considered when choosing.
(a) packaging speed. To improve the production efficiency, double chamber or multi-chamber vacuum packaging machine can be selected to improve the overall production efficiency.
Progress of production.
(b) whether the packages need to be filled with other protective gases. Optional multifunctional vacuum packaging machine with inflating device.
(c) requirements for the degree of vacuum of the packaged goods. If the packaged items need to be well preserved under the condition of high vacuum degree, you need to choose a cavity vacuum packaging machine.
d) The requirements of the vacuum packaging machine of the condition of the packaged items.
The vacuum packaging machine has been used in many fields ZHEJIANG HONGZHAN PACKING MACHINERY CO., LTD maintains close relationships with customers in the vacuum packaging machine industry, and is committed to strengthening production and operation, as well as improving quality and safety.
