Are all kinds of bottle caps really suitable for packaging Chinese liquor?-Part 4

In the current liquor, metal screw caps, plastic screw caps, polymer plugs, plastic jacket plugs, etc. are commonly used. For these plastic-related caps and plugs, presumably after the "plasticizer" incident, the industry and liquor companies There will be strict requirements on the plastic material. For the plastic inner packaging material in the liquor field, the use of "plasticizers" is not allowed.

Polymer stoppers are popular among many wine companies at present. They have good airtightness and are environmentally friendly. However, this kind of stopper has not been popular in the liquor field for a long time, and it will take time to test it.

Generally speaking, for liquor packaging, beer caps, wooden stoppers and rubber stoppers are not suitable for packaging with liquor. It is uncertain whether the long-term storage of liquor sealed by beer caps and corks is sealed; It is easily corroded by liquor, and it is uncertain whether it will dissolve other substances into the liquor body. In contrast, gold screw caps, plastic screw caps, polymer plugs and plastic overcoat plugs are all ideal packaging methods for liquor, but for plastic screw caps and plastic plugs, the plastic products must not contain "plasticizers" Yes, it must meet the requirements for liquor packaging. We have different sealing measures for different bottle caps and corks. For old wine with beer caps, I don’t recommend doing too many sealing measures at the bottle mouth. For old wine with plastic film, I don’t recommend too much sealing at the bottle mouth. Many packaging measures, after all, these measures are easy to damage the appearance of the film, for collection, the appearance is the most important.
