The 3 side sealing packaging machine has two methods: upper paper feeding and down paper feeding, so how to choose these two methods?
Upper feeding paper is to place the packaged product under the packaging film with the packaging film on the top. It is more suitable for some fixed-size products, which is not easy to be damaged, good for transportation, and has regular product packaging.
Down paper feeding is to place the packaged product on the packaging film, which is suitable for the packaging of products that are not easy to transport and have stickiness, and some irregular products can also be packaged.
