• Oxygen exclusion The flexible inner pouch shrinks as the oil is dispensed, meaning no air enters the container to replace the liquid as it does with a bottle. This prevents oxidation, which is the primary cause of rancidity and flavour degradation in olive oil.
• Light protection The opaque outer box blocks light exposure entirely, protecting the oil from photo-oxidation — a process that breaks down polyphenols and other compounds responsible for olive oil's fresh, peppery, and fruity notes.
• Seal integrity: The one-way tap creates an airtight seal between pours, unlike bottles that are repeatedly opened and exposed to ambient air. This means the last drop tastes nearly as fresh as the first.

Polyphenol protection: Olive oil's potent antioxidants (including oleocanthal and oleuropein) degrade rapidly when exposed to oxygen and light. The shrinking & opaque pouch minimise both, helping maintain the anti-inflammatory and cardiovascular benefits these compounds provide.

Preservation of oleic acid integrity: While oleic acid (olive oil's primary healthy monounsaturated fat) is relatively stable, oxidation over time can still compromise its quality. The airtight, air-free environment of bag-in-box slows this process, ensuring the oil retains its heart-health properties throughout its shelf life.

Vitamin E retention: Olive oil is a natural source of tocopherols (Vitamin E), which are fat-soluble antioxidants that support immune function and skin health. These compounds are particularly sensitive to oxidation and light exposure, and the protective environment of bag-in-box packaging helps ensure they remain intact and bioavailable throughout the product's use.

• 8.8x lower carbon footprint than glass bottles Life Cycle Assessments conducted by a leading pouch manufacturer consistently shows bag-in-box has significantly lower global warming potential than glass, making it one of the most impactful packaging switches a brand can make for emissions reduction.

• Dramatically lighter packaging weight A 10-litre bag-in-box weighs just 359g, compared to 2.5kg for a metal jerrycan of the same size - and far more versus equivalent glass. This weight reduction compounds across the entire supply chain, cutting energy use at every stage from production to delivery.

• Glass manufacturing is extraordinarily energy-intensive Producing glass requires temperatures exceeding 1,500°C, consuming around 8,910 megajoules per 1,000 bottles — whereas bag-in-box materials (predominantly cardboard and lightweight polyethylene film) require a fraction of that energy to produce.
