In heat shrink packaging, there are many single packagings and many combined packagings. When encountering combined packaging, we must pay attention to several things:
1. Whether the combination is combined manually or by shrink wrap machine. Many products are automatically arranged during the previous stage of blanking, and can be combined automatically;
2. The size of the combined package needs to conform to the packaging principle after the combination. What does this specifically mean? It is the product of the combination package, the length, width, and height should be long in the length direction, not long to the width direction, and should conform to the principle of the product’s trajectory;
3. After the combination package is covered by the film, when it enters the shrink wrapping machine, whether it needs to be sorted out once. Some customers have higher packaging requirements, so they will need to wrap the film and arrange it, so that it will be neat when shrinking;
4. Choose a shrinking furnace for combined packaging. At this point, we recommend using a tandem-shaft conveying furnace, because the tandem-shaft furnace has a self-rotation function, which has a great impact on the shrinkage effect of the bottom. If the product is small , There will be a risk of getting stuck in the serial axis, then encrypt the serial axis and make a close connection type to solve this problem.
To sum up: Combination packaging needs to pay attention to understanding the shape of the product, the speed of the product, whether the integration is automated, whether the packaging process will run away, and whether the shape will change during the shrinkage of the product. After paying attention to the above points, everything can be done.
