PET or glass for olive oil?
Olive oil has long been sold in glass. For export and retail, more and more packers are looking at PET. Here is what to compare before you choose, without taking sides.
Weight and freight
Much lighter than glass: fewer breakages on the line, in transit and on the shelf, and lighter export freight.
In the 3P range, a 750 ml bottle weighs 65 – 70 g depending on the model (2026 catalogue values; some weights are given on request). A glass bottle of the same capacity weighs considerably more: across a pallet or a container, the difference shows up in your freight costs.
Breakage on the line and on the shelf
Glass can break at every step: filling, capping, palletising, transport, shelving, and at the customer's home. Each breakage costs the bottle, the oil inside it and the time spent cleaning the line. PET reduces those losses; it does not replace testing your own supply chain.
Protection from light
Light and heat speed up the oxidation of olive oil and wear down its aromas. Here the tint matters before the material: clear glass protects as little as clear PET.
Dark tints (black, amber, olive green) limit the oil's exposure to light. To choose one, see our tint guide.
Food contact
Virgin material intended for food contact. Declaration of conformity (Regulation (EU) No 10/2011) on request.
Both glass and food-grade PET are used for olive oil. For each product, compatibility is confirmed by trials: acidity, filling temperature and the shelf life you are aiming for.
Gas barrier and shelf life
Glass is practically impermeable to oxygen; PET less so. For an oil meant to keep for a long time, validate its shelf life in the chosen bottle, with the intended tint and cap, before production starts.
Recycling
Recyclable PET, with the sorting symbol moulded into the base of every bottle. Glass is recyclable too: in both cases, the collection schemes in your markets make the difference.
On your filling line
All eight bottles share the same neck. One cap to stock, no capping changeover on your line. The FT21/29 cap fits the whole range.
Flat faces, smooth barrels or framed label areas: for labelling, the shape matters as much as the material. compare the shapes in the range to find the one that suits your labeller.
Where glass still does better
Glass remains the reference in some markets and for some very high-end ranges, and it is the better gas barrier over long periods. PET makes sense when weight, breakage and logistics costs matter: export, retail, family sizes and food service.
How to decide
Compare real bottles: turn the models around in the 3D configurator, then request samples to test filling, capping and labelling on your own line.
