Introducción completa a las botellas de vidrio para cosméticos

In addition to the effectiveness of its products, whether a cosmetic product can sell well also depends crucially on whether its design can immediately catch consumers' attention. However, many cosmetics brands lack knowledge of packaging materials when choosing cosmetic packaging. To ensure that their brand captures customers' attention immediately, it is undoubtedly essential to select appropriate packaging materials and perfect designs.

Non-toxic and Impermeable: Cosmetic glass bottles are recognized in the cosmetics packaging market for their notable characteristics. This is primarily because using cosmetic glass bottles has several advantages:

 1. Glass material is lead-free and non-toxic, with excellent barrier properties. It effectively prevents oxidation and the penetration of various gases into the contents of the bottle. Simultaneously, it can efficiently inhibit the volatilization of volatile components from the contents.

   2. Glass bottles can be recycled repeatedly, reducing packaging costs for businesses and benefiting environmental protection.

   3. Glass is transparent, allowing the contents to be clearly visible. The combination of aesthetics and functionality conveys a sense of luxury to consumers.   

   4. Glass bottles are safe and hygienic, non-toxic and harmless, with good corrosion resistance and acid resistance capabilities, providing special packaging advantages for the cosmetics industry.

Glass bottles are widely used in cosmetics for various purposes, including creams, serums, toners, and essential oils. They are categorized based on their application and design, such as:

1. Cream Jars: Used for solid or semi-solid skincare products like creams and masks. They typically feature wide mouths and can be paired with aluminum or plastic caps. The caps can be customized with color spraying effects.

2. Serum Bottles: These narrow-necked bottles are suitable for emulsions or liquid formulations. They often come with pumps for dispensing, or if fitted with caps, they include inner seals to prevent leakage. For watery products, they may have small hole inner seals, while thicker emulsions use larger hole inner seals.

3. Essential Oil Bottles: Usually amber-colored or frosted to protect contents from light degradation. They are equipped with caps featuring safety rings and can be paired with inner seals or droppers for controlled dispensing.

4. Perfume Bottles: These bottles are typically designed with elegant spray pumps or plastic caps for easy application.

Glass bottles are rarely used for cosmetics in capacities exceeding 200ml. They are further categorized into wide-mouth and narrow-neck types to suit different product viscosities and dispensing methods, ensuring both functionality and aesthetic appeal in cosmetic packaging.

Here are the combinations for different types of glass bottles used in cosmetics:

1. Cream Jar Series: Glass bottle body with a double-layer plastic outer cap. Typically used for capacities ranging from 10g to 50g.

2. Serum Bottle Series: Glass bottle body with a plastic pump head or anodized aluminum pump head. Usually used for capacities ranging from 20ml to 100ml.

3. Toner Bottle Series: Glass bottle body with a plastic inner seal and outer cap. Suitable for capacities over 100ml, sometimes also available with a pump head.

4. Essential Oil Bottle Series: Glass bottle body with an inner seal, a bulb dropper or pipette, and an anodized aluminum cap or a plastic cap with a large head.

The processing techniques for coloring glass bottles used in cosmetics:

1. Anodized Aluminum: Aluminum-based appearance with a film wrapped on the inner layer of plastic. This method provides a metallic look.

2. Electroplating (UV): Produces bright colors compared to spray coating.

3. Spray Coating: Produces matte colors compared to electroplating. There are two methods of spray coating:

   - Inner Bottle Outer Spray: Spray coating on the outer surface of the inner bottle. There is a noticeable gap between the inner and outer bottles when viewed from the outside, with a smaller spray area visible from the side.

   - Outer Bottle Inner Spray: Spray coating on the inner surface of the outer bottle. This method appears larger in area when viewed from the outside, with no gap visible between the inner and outer bottles.

4. Brushing Gold or Silver: Involves applying a film that can be observed with careful inspection on the bottle body where there are visible seams.

5. Secondary Oxidation: Applies a secondary oxidation layer on top of the existing oxide layer to achieve a glossy cover with matte patterns or matte cover with glossy patterns. This method is commonly used for creating logos.

6. Injection Molding Color: Adds color powders into the raw material during injection molding. This process is relatively inexpensive and can include additives like pearl powder or talcum powder, which can change the transparency of PET from clear to opaque.

Here are the printing techniques commonly used for decorating glass bottles in cosmetics:

1. Screen Printing:

   - High-temperature ink screen printing: Features ink that is resistant to fading, but colors may appear muted. Achieving a purple hue can be challenging.

   - Low-temperature ink screen printing: Offers vibrant colors but requires high-quality ink to prevent easy peeling. Considerations for bottle sterilization are important.

2. Hot Stamping:

   - Thin foil is stamped onto the surface, lacking the raised texture of screen printing. It's advisable not to directly hot stamp on PE and PP materials; instead, perform heat transfer printing first or use suitable hot stamping foils.

3. Water Transfer Printing:

   - Involves irregular printing done in water, resulting in inconsistent patterns. This method tends to be more expensive.

4. Heat Transfer Printing:

   - Used for large quantities or complex print designs, involving applying a film onto the surface. This method is relatively costly.

5. Offset Printing:

   - Commonly used for aluminum-plastic and all-plastic collapsible tubes. When printing white on colored squeeze tubes, screen printing is preferred to avoid the underlying color showing through. Sometimes, a glossy or matte film is applied to the squeeze tube surface.

These printing techniques offer various aesthetic and functional benefits, catering to different requirements in cosmetic packaging design.

Ordering and Transporting Cosmetic Glass Bottles: 

Cosmetic glass bottles have a longer production cycle, ranging from 20 days at the quickest to up to 45 days for some supply periods. Typically, orders range from 5,000 to 10,000 units, with smaller bottle sizes requiring larger minimum quantities. Production lead times and minimum order quantities are affected by peak and off-peak seasons. For transportation, it is advisable to use paper or foam packaging, individually separated, and supplemented with inner trays and outer cartons to enhance shock resistance.
