How to foil seal laminated soft tube?
1,Before starting to apply the foil seal on the soft tube mouth, the first important thing we need to do is to clean the mouth. The tube mouth must be dry and clean, so that the foil seal will be strongly stuck to the mouth. If the tube mouth is dirty and full of dust, it will affect the sealing effect.
2, Peel off the tube foil seal from the paper sheet, apply it to the surface of the tube mouth and smooth it by your finger. At this moment, the foil seal looks smoothly from the appearance.
3, Screw on the plastic lid to the tube mouth. It will tighten the foil seal strongly. If you reopen the plastic lid, you will find the foil seal perfectly sticking to the mouth surface, which means everything are done.
