Which Type of Bottle Cap Is for Olive Oil

The material selection of the olive oil bottle cap directly affects the quality and brand image of the oil. The current mainstream materials in the market can be divided into three categories:

1. Food-grade TPE (thermoplastic elastomer)

Core advantages: It has both the elasticity of rubber and the processability of plastic. It passes the n-heptane test and distilled water test to ensure that there is no migration of harmful substances when in contact with oil.

Performance:

High sealing: The inner plug structure uses TPE material, which can withstand high-temperature cooking at 130℃ to prevent oil leakage.

Environmental protection characteristics: The scraps can be recycled and reused, which complies with EU REACH and US FDA standards and reduces carbon footprint.

Typical application: European high-end olive oil brands generally use TPE inner plugs with aluminum outer caps, taking into account safety and texture.

2. Aluminum bottle caps

Market position: The global aluminum bottle cap market share continues to grow, accounting for nearly 35% of the European wine market, and the penetration rate in the olive oil field is rapidly increasing.

Technical highlights:

Anti-oxidation barrier: The high barrier property of aluminum can isolate oxygen, extend the shelf life of olive oil to more than 3 years, and avoid the increase in acid value caused by oxidation.

Sustainability: The energy consumption of recycling is only 5% of the original aluminum production, and it can be recycled infinitely. The life cycle assessment (LCA) shows that it has minimal environmental impact.

3. Plastics and composite materials

Economical choice: Injection-molded plastic bottle caps are low-cost, easy to process, and suitable for large-scale production, such as the patented plastic bottle caps used by Beidahuang Group.

Composite solution: Aluminum-plastic three-piece bottle caps combine the sealing of aluminum with the lightness of plastic, and are often used in export products.

Core advantages of oil bottle caps

1. Quality guardian

Antioxidant barrier: Aluminum bottle caps can reduce the oxidation rate of olive oil by 60% and maintain its monounsaturated fatty acid (MUFA) content.

Pollution prevention: TPE inner plugs pass the n-heptane test to avoid plasticizer migration and ensure oil safety.

2. Sustainable pioneer

Circular economy: The recycling rate of aluminum bottle caps exceeds 80%, and TPE materials can be repeatedly processed 6 times without deterioration.

Lightweight trend: Aluminum bottle caps are 50% lighter than traditional corks, reducing transportation energy consumption.

3. Good using experience

Easy to open: Aluminum screw caps do not require a bottle opener, and the rotation force is only 1.5N, which is much lower than the 8N of corks.

Precise control: The leak-proof reflux structure makes the error of each pouring less than 0.1ml, which is suitable for healthy eating scenarios.

4. Brand enabler

Visual identification: Customized bottle cap design (such as hot stamping, embossing) can increase product premium, and the premium rate of high-end brands can reach 20%-30%. Haomei Aluminum support the customization of the cooking oil bottle cap.

Digital interaction: The bottle cap is embedded with NFC chip or QR code to realize product traceability and marketing interaction.
