Fresh-keeping Box Sealing Machine Tells You What To Do If The Seal Is Not Tight

For Modified Atmosphere Packaging Equipment, it is a common problem that the seal is not tight or the mouth is not sealed. This is also a very troublesome problem for users. It affects production and has certain damage to the product. It cannot guarantee the quality of the product, thus affecting the purchase of consumers. Let's get down to business. Why is the sealer not tight or the seal is not tight? What should I do if the sealer cannot seal? Let's take everyone to understand it today.

What should I do if the sealer cannot seal? The sealer manufacturer will tell you: the sealing part of the sealer has not reached the appropriate temperature; under the pressure of the sealing knife, the bag mouth is sealed, but if you press or peel it with a little force, the seal will break again; when the sealer performs a peel test on the sealing part, half of the seal is firm and half of the seal is separated. The sealing quality of such packaging bags is still unqualified because their contents are prone to leakage after being squeezed during storage and transportation.

The failure of the sealing mouth is also related to the speed of the sealer. If the speed is too fast, the seal will be transported to the cold pressing part by the traction roller for cooling before heating, and naturally cannot meet the quality requirements of heat sealing. The sealing failure of the sealing machine is also related to the quality of the heat-sealed film. If the corona treatment of the composite lining is uneven, the effect is not good, and it happens to appear at the sealing point, it is impossible to seal.

The above is the reason why the sealing machine cannot seal summarized by the sealing machine manufacturer. Only by finding the cause and handling it reasonably can we improve efficiency and effect without delaying production.
