Our company also has a Foil Seal. If you are sealing, then we will separate the lid and the tube for you. We will also include a foil seal for you. If you want to lock the lid and not seal it, we will help you at the head. Adhering to the foil seal has the advantage that, in case you fill your product with your paste, the paste flows out of the head and the customer experience does not feel very good.
