History of Olive Oil Bottle Caps
Before the mid-20th century, in the early stages of industrial olive oil production, olive oil was mostly packaged in glass bottles sealed with cork stoppers or metal press-on caps, but these provided limited sealing performance.
By the late 1970s to 1980s, with the advancement of food-grade aluminum alloy processing and the development of pilfer-proof structures, twist-off aluminum anti-theft caps were first applied in the wine and spirits industries. Due to their light weight, corrosion resistance, printability, and recyclability, olive oil producers began adopting aluminum pilfer-proof caps for olive oil packaging, inspired by the wine packaging sector.
Today’s olive oil bottle caps not only focus on pilfer-proof, leak-proof, and anti-oxidation features, but also emphasize environmental protection and recyclability. As a result, aluminum caps have become the mainstream choice for premium olive oil packaging worldwide.
HAOMEI Olive Oil Bottle Caps
The screw-type aluminum pilfer-proof cap for olive oil is made from 8011-H18 aluminum sheet as the core material. It uses a serrated pilfer-proof ring combined with break-off bridges to provide physical anti-counterfeiting, paired with a food-grade sealing liner to ensure oil freshness. HAOMEI Aluminum offers printing, laser micro-coding, and RFID options to enhance the anti-counterfeiting level.
In the olive oil packaging industry, the most common and widely used size is 31.5x24mm. HAOMEI Aluminum’s olive oil caps are precisely matched to bottle neck standards such as BVS and ROPP to meet customers’ requirements.
Why Is Aluminum the Preferred Choice for Olive Oil Sealing?
