There are usually several reasons for bubbles appearing on cosmetic glass bottles:
1. Production process issues:
-During the glass blowing process, improper temperature control or inadequate blowing techniques may lead to the formation of bubbles.
2. Quality issues with raw materials:
-If there are impurities or gases in glass raw materials that cannot be completely released during high-temperature melting, bubbles will form in glass products.
3. Introduce air during the packaging filling process:
-If air is mixed in due to improper operation during cosmetic filling, bubbles will eventually form inside the glass bottle.
4. Thermal expansion and contraction effects:
-Glass bottles undergo thermal expansion and contraction when the temperature changes, which may cause pressure changes inside the bottle and form bubbles.
5. Cosmetics ingredients react with glass:
-Some ingredients in cosmetic formulas may react chemically with glass materials, producing gases and forming bubbles.
In general, the bubbles is often caused by various factors such as production processes, raw material quality, and cosmetic filling processes. Cosmetics production enterprises need to strictly control each link to ensure the quality of glass packaging.
