Why Can't Vacuum Sealers Seal Vacuum Storage Bags Tightly?
Featuring the excellent performance of vacuum pumping, small size, simple structure and being easy to use, vacuum sealers have gained great popularity in many families, with the preservation of food sealed in vacuum bags being prolonged at normal temperatures. However, many people are full of thoughts about the seal problem of vacuum sealers which has brought losses to people. So, is it the problem of machines or bags indeed? The following is to share some reasons why can't vacuum seals seal vacuum storage bags tightly with you.
First, the top of the bag left for sealing is too short. In general, a vacuum bag with food needs to be left at least 3-5cm for sealing. If the distance is too short, it is possible for the top to occur folds or be uneven in length when the rubber strip presses down so that the bag can not be sealed properly.
Second, the time for vacuum pumping is insufficient. In order to improve work efficiency, many people may set a brief time for sealing. However, lack of time will go against the operation of the airbag in the vacuum chamber, influencing the effect of sealing and leading to the possibility of air leaks.
Third, the heat-resistant cloth is not installed well. Thermal insulation cloth is an easy-damaged part of vacuum sealers, which need to be replaced after a long time of use. Some people may not pay too much attention while changing the cloth so that some folds will occur on vacuum bags when the rubber strip presses down due to the loose heat-resistant cloth, affecting the effect of sealing bags.
Fourth, the problems of vacuum bags. Sometimes the problems of bags may become the bottom of sealing loosely. For example, we use common plastic bags instead of vacuum bags. The bags are soft which is lack of solidity. Or the top of bags is full of oil and water. At this time, we ought to spend time choosing suitable and durable vacuum bags.
To sum up, under the circumstances of the normal operation of vacuum sealers, the problem of sealing will rarely happen. Once vacuum storage bags are sealed well, air leaks will not occur.
