Cosmetic glass bottle packaging introduction

With high transparency and corrosion resistance as the core advantages, cosmetic glass bottles are adapted to the needs of the whole category from portable samples to high-end formalwear through the differentiated design of capacity, sealing and surface technology.

I. Core Materials and Characteristics

• Material Composition

Glass type: high borosilicate glass (high temperature resistance, corrosion resistance) or soda-lime glass (low cost, high transparency), suitable for serums, perfumes and other high-value liquid products.

Surface treatment: frosted, sprayed (to enhance texture) or transparent and polished (to display contents).

• Sealing design

Airtight structure: Silicone gasket or screw cap design to prevent liquid evaporation or leakage.

Matching tools: some need to be used with dropper or pump head (e.g. serum bottle).

II. Common specifications

• Parameter item Typical range Example products

Volume 3ml-50ml (sample to full size) 3ml bottle (vacuum design, suitable for eyeliner)

Bottle diameter 5mm-20mm (suitable for different pump heads) 0.35ml liquid eyeliner (Φ9.6mm bottle)

Bottle height 50mm-150mm

Cap material Plastic, metal or bamboo (eco-friendly option) Bamboo cap liquid eyeliner bottle (PET empty tube)

III. Design highlights and adaptable scenes

• Functionality

Vacuum bottle: to avoid oxidization of the content (such as high active serum), need to be pressed to dispense liquid.

Dropper bottle: precise control of dosage, commonly used for essential oils or high-concentration original liquid.

• Environmental Trends

Recyclability: Glass bottles are recyclable and meet EU REACH environmental standards.

Lightweight design: thin-walled glass process (reduce material consumption and cost).

IV. Production process and standards

Temperature resistance: high borosilicate glass can withstand temperature difference from -20℃ to 300℃ (suitable for autoclavable products).

Printing process: silkscreen, hot stamping or laser engraving (to ensure the durability of the label).

Safety certification: FDA (U.S.) or GB (China) food-grade packaging certification is required.

V. Comparison of popular product parameters

Vacuum Dispenser Bottle 3ml Screw Cap + Silicone Seal Eyeliner, Nail Polish

Dropper Essence Bottle 30ml Dropper + Frosted Glass Serum, Essential Oil

Perfume Spray Bottle 50ml Metal Pump Head + High Transparency Glass Perfume, Styling Spray

VI. The environmental protection of cosmetics glass bottle packaging

• Recyclable and recycling

Glass bottles can be recycled indefinitely, reducing resource waste and in line with the concept of sustainable development.

Recycled glass bottles can be converted into new packaging through melt regeneration, reducing the consumption of raw materials.

• Production Process and Energy Consumption Controversy

Glass production requires a large amount of raw materials such as quartz sand and soda ash, and the high-temperature melting process consumes high amounts of energy, which may have a negative impact on the environment.

Lightweight design (thin-wall process) is gradually gaining popularity, reducing material use and lowering transportation carbon emissions.

• Expanded reuse scenarios

Empty bottles can be transformed into decorations or storage containers (e.g. flower vases, jewelry boxes) to extend the life cycle.

VII. Safety

• Chemical Stability and Ingredient Protection

Glass is an inert material that does not react with cosmetic ingredients, avoiding the risk of migration of harmful substances (e.g. plasticizers in plastics).

High sealing prevents external factors such as oxygen and ultraviolet rays from destroying active ingredients (e.g. serums, essential oils).

• Potential Risks and Precautions

Metal additives: some colored glass may contain metal oxides (e.g., lead, cadmium), requiring food-grade safety certification (e.g., FDA, GB).

Physical fragility: glass is fragile, and anti-drop design (e.g., thickened bottle, silicone protective sleeve) is required for transportation or use.
