1. Material of vacuum laminator
Generally speaking, regular manufacturers use stainless steel to produce vacuum laminators. If the vacuum laminator is used in the food industry, the vacuum laminator must also be made of stainless steel, but when it is used to package metal and some special items, or when the environment is relatively dry, it can be made of iron (considering the cost The situation can also use iron as appropriate). Comparing the vacuum packaging machines of the two materials, the performance of the stainless steel vacuum packaging machine must be better and relatively safer. 304 stainless steel is the best choice for the production of vacuum laminators. So before you buy, you must figure out the material of the vacuum laminator.
Second, the quality of the original parts and accessories in the machine
Conscience merchants generally use better quality accessories when making production. Therefore, when you have the intention to buy a vacuum laminator, you should not blindly choose a machine of poor quality in order to save money, and conscientious manufacturers basically There will be more sets of parts for vulnerable objects.
Third, the quality of the vacuum pump in the machine
The power and quality of the vacuum pump are very important points that determine the quality of the vacuum machine. Before you buy the machine, you should consult the manufacturer of the vacuum pump. Pay attention to the maintenance of the vacuum pump. No matter how good the quality is, the vacuum pump will have problems sooner or later if it is not maintained.
Fourth, the operating speed of the machine
Before buying, you must also figure out the packaging requirements (such as size, weight) of the vacuum laminator and the packaging speed of the machine. Generally, the time of air extraction for the machine seal is adjustable.
Five, understand the classification of vacuum laminator
There are two types of vacuum laminators: external type and internal pumping type. Both models have the same effect. External vacuum packaging machines are generally suitable for items that do not require a high degree of vacuum (such as electronic parts, etc.). The internal pumping vacuum packaging machine is generally suitable for items with relatively high vacuum requirements (such as food, etc.).
