Six Solutions Of Shrink Wrapping Machine with Poor Effect.

 Shrink wrapping machine is very popular packaging solution in the market, suitable for a variety of box, bottle, container, books, and irregular shape items. At the same time, it adopts advanced film constant temperature heat sealing and shrinking technology, which has high sealing strength, transparency and firmness, and prevents the products from being scattered due to transportation and instability. Moreover, the machine equipment is equipped with an induction switch to control the film feeding system.

After it has been used for a period of time, it will more or less wrinkle, so that it can not achieve the actual effect of the expected packaging, which will affect the normal production and processing. Please do not worry, and refer to the following solution, or contact SNCPACK after-sales customer service, we will provide customers with a solution

Six Solutions Of Shrink Wrapping Machine with Poor Effect

1. The shrink temperature is insufficient.

Solution: increase the temperature (if there is more at the top, increase the heating temperature, and on the contrary, lower the heating temperature). If the temperature is high enough, try to slow down the speed of the conveying belt and make it take longer to shrink the tunnel, which will improve the actual effect of shrinkage.

2. The wrapped surface is wrinkled after heat shrinking.

Solution: Adjust the sealing size for wrapped bag. Most shrink packaging machines are made of a combination of a sealing and cutting machine and a shrinking furnace, which first completes the bag sealing and then shrinks. If the front bag size is too large, the film will be wrinkled after shrinkage. At this time, the sealing size can be adjusted to make the bag smaller. Usually, the margin of the film is about 1/2 of the product height.

3. Large cracks or imperfect shrinkage on the exterior surface.

Solution: adjust the perforation on the surface of the film. The film used in fully enclosed shrink wrapping needs to be perforated in order to exhaust air close to the surface of the product, or the front sealing and cutting machine will also be equipped with a punching device, which will cause wrinkling on the surface if it is drilled too much and exhaust too fast. and if the holes are too less that will cause the exhaust not smooth to cause the breach. So adjust the perforation on film is important.

4. There is opening mouth at the sealing position.

Solution: improving the sealing result of sealer; sometimes because the sealing of the sealer is not good, it will cause a break in the sealing line after shrinkage. If the knife edge is dirty, the sealing temperature is not suitable, and the sealing pressure is not suitable, both of those reasons will cause bad sealing effect. then improve the sealing and cutting effect according to the operation knowledge of the sealing machine.

5. The shrink film is not good.

Solution: change good quality of shrink film. In the case that the problem cannot be solved by the above 4 solutions, is the quality of the heat shrinkable film poor? If the proportion of contraction is small and the flexibility is not enough, we can only change shrink film with good quality.

6. The shrinkage effect still not improved after tried all the solutions.

Solution: Do fully comprehensive maintenance or replace with new machine. If the equipment is deformed after long-term use, resulting in blockage of the drying channel, uneven blowing and unstable temperature in the heating zone, it is necessary to comprehensively go to the machine for maintenance, replace spare parts, or directly replace the machine.
