HAOMEI Aluminum produces 30x24mm pilfer-proof aluminum bottle caps designed specifically for premium edible oil products such as olive oil, flaxseed oil, and sesame oil. The company uses SACMI CCM64MD equipment, capable of producing up to 2,850 caps per minute, ensuring high daily output and fast delivery times. We offer customized surface embossing of logos or anodized coloring (such as gold or dark green) to enhance the premium visual appeal.
HAOMEI Aluminum manufactures caps in 30x24mm and 31.5x24mm sizes, compatible with standard olive oil glass bottles or PETG wide-mouth bottles. The olive oil cap features a breakaway pilfer-proof ring that breaks upon opening, ensuring visible first-open security.
Advantages of Aluminum ROPP Caps for Olive Oil
Aluminum ROPP (Roll-On Pilfer-Proof) caps provide a standout packaging solution for olive oil with the following advantages:
Freshness Preservation: Aluminum effectively blocks light and oxygen, protecting the quality of olive oil and preventing degradation.
Anti-Tampering: ROPP design ensures tamper-evident sealing, safeguarding product authenticity and enhancing consumer trust.
Aesthetic Appeal: Aluminum caps offer a stylish appearance, improving the overall look of the olive oil bottle and supporting brand differentiation.
Sustainability: Aluminum is 100% recyclable, aligning with environmental trends, and its lightweight nature reduces transport costs and emissions.
Corrosion Resistance: Aluminum’s natural oxide layer, along with specific alloys and coatings, boosts its resistance to corrosion.
Types of Olive Oil Aluminum Cap Liners
Polyethylene (PE) / Expanded Polyethylene (EPE): Common universal liner materials with good chemical resistance to oils, acids, alkalis, and solvents, low moisture vapor transmission rate, and strong flavor/odor barrier. EPE foam is a single-layer structure of low-density expanded polyethylene.
Saranex™ and Saran™tin: FDA-approved proprietary liners for high-barrier applications.
Saranex™ is a single-layer EPE foam laminated on both sides with SX film (PE-PVDC-PE), ideal for oxygen-sensitive products, allowing controlled oxygen permeation.
Saran™tin is a single-layer EPE foam laminated with two LDPE layers, an aluminum foil barrier, and a PET film layer for maximum oxygen barrier—perfect for products that require no aging.
