Matters needing attention for cosmetic packaging glass materials:
1. Hand-processed glass bottles: If the cosmetic packaging glass material is made by hand-molding, there will be a little deviation in capacity. When selecting it, it should be tested and marked with the correct capacity. For example, the automatic production line is relatively uniform, but the shipment volume is relatively high. Large, the cycle is relatively long, and the capacity is relatively stable.
2. The thickness of the glass bottle: The uneven thickness of the glass material for cosmetic packaging will easily lead to damage, or it will be easily crushed by the contents under severe cold conditions. A reasonable capacity should be tested during filling, and paper bags should be used for transportation. Separated, the product should be equipped with a color box, and the inner support and middle box can play a more shockproof role.
3. Sealing of glass bottles: Cosmetic packaging glass material bottle cap technology can be used for anodized aluminum lettering, bronzing edges, etched lines, and there are matte and bright colors. Gaskets and inner caps are required. It is recommended to use pressure-sensitive sheets to strengthen the seal. Effect.
