Classification of cosmetic packaging glass materials:
Cosmetic packaging glass materials are classified into wide-mouth bottles and narrow-mouth bottles. Solid pastes are generally used in wide-mouth bottles, which are suitable for aluminum or plastic caps. The caps can be used for color spraying and other effects; emulsion or water A narrow-mouth bottle is generally used for the agent type paste, and a pump head should be used. Pay attention to prevent the spring and ball from rusting. Now most pump heads are equipped with glass beads, which are usually used for material testing and applicable tests. If the cover is equipped, an inner plug is required , Liquid with small holes is the same as inner plug, thicker emulsion is matched with large hole inner plug.
Common bottle types of cosmetic packaging glass materials:
Cylindrical, oval, flat, prismatic, cone, etc., manufacturers often develop series of bottle shapes. The bottle body process includes spraying, transparent, frosted, translucent toning, silk screen, bronzing, and silver bronzing. There are usually two types of screen printing for cosmetic packaging glass materials. One is high-temperature ink screen printing, which is not easy to decolorize, the color is dull, and it is difficult to produce purple color toning. The other is low-temperature ink screen printing, which is brighter in color. The requirements are high, otherwise it is easy to fall off, and attention should be paid to the bottle disinfection.
Matters needing attention in cosmetic packaging glass materials:
1. Hand-processed glass bottles: If the cosmetic packaging glass material is made by hand-molded, there will be a slight deviation in the capacity. It should be tested and marked correctly when selecting it. For example, the automatic production line is more uniform, but the shipment volume is more demanding. Large, relatively long cycle, relatively stable capacity.
2. The thickness of the glass bottle: the uneven thickness of the glass material for cosmetic packaging can easily cause damage, or it can be easily broken by the content under severe cold conditions. A reasonable capacity should be tested during filling, and a paper package should be used for transportation. Separate, the product should be equipped with a color box, the inner support and the middle box can play a more anti-vibration effect.
3. Glass bottle sealing: The process of cosmetic packaging glass material bottle caps can be anodized aluminum lettering, bronzing, etched lines, there are matt bright colors, gaskets and inner caps are required, and it is recommended to use pressure-sensitive films to strengthen the seal effect.
