What is the reason why the vacuum packaging machine is not tight

the reason why the vacuum packaging machine is not tight and the solution:

first, the vacuum packaging machine is not completely vacuumized, resulting in air residue in the bag, which can not form an effective negative pressure and looks not tight

Second, there is a problem in the sealing process of the vacuum packaging machine, resulting in air leakage at that time or later, resulting in small vacuum and loose bag

solution: repair the machine and check it to ensure the tightness of the bag and the integrity of the machine operation

Vacuum refers to the gas state below an atmospheric pressure in a given space. Vacuum packaging means that all the air in the packaging container is extracted and sealed to maintain the bag in a highly decompressed state. The scarcity of air is equivalent to the effect of low oxygen, so that microorganisms have no living conditions, so as to achieve the purpose of fresh fruits and no disease and rot

behind vacuum packaging

vacuum packaging can ensure that products are not polluted by the environment and prolong the shelf life of food. It is particularly common and practical in daily life. The key point of vacuum packaging is to discharge oxygen. Draw out the oxygen in the package, so that microorganisms have no living space, so as to keep the food fresh

like our usual independent packaging, it is directly sealed without going through the step of “deaeration”, which is not a real vacuum packaging. Vacuum packaging is very useful in daily life, but it can’t be used to store white tea

if it is not tight, there are two possibilities.
first, the vacuum packaging machine is not completely vacuumized, resulting in air residue in the bag, which can not form an effective negative pressure and looks not tight
Second, there is a problem in the sealing process of the vacuum packaging machine, resulting in air leakage at that time or later, resulting in low vacuum and loose bag

Qingdao Aixun vacuum packaging machine uses high-quality accessories with good sealing effect. The use of high-quality brand vacuum pump ensures the effectiveness of the vacuum pumping process.

Answer

 Hello, I'm glad to serve you 

 please wait patiently. We are answering the questions for you
 Hello, about your problem, the automatic vacuum packaging machine can't seal tightly. Why? After some analysis, I'll give you the following explanation

1. It is the incomplete vacuum pumping of the vacuum packaging machine, resulting in the residual air in the bag, which can not form an effective negative pressure and looks not tight

2. There is a problem in the sealing process of the vacuum packaging machine, resulting in air leakage at that time or later, resulting in small vacuum and loose bag

Ask questions

 How do you do it 

Answer

 it is recommended that you use cartons for bundling. If the same is true after bundling, it means that the tightening force is adjusted too little or the unwinding time is not enough. Just adjust it on the control panel of the machine. If the full-automatic packaging machine can bind the cartons well, it means that it is not the problem of the equipment, but the inelasticity of the items you bind

Ask

 How do you repair it
Answer
 the main reason is that this kind of products do not have resilience. When the equipment needs to be bonded, the packaging rebound is too large, resulting in the loosening of the packaging belt. In this case, users and customers place some paper shell items at the binding position for cushioning, or make the equipment cover thinner to make the hot head close to the product, and the effect will be better
