Juice & Smoothie Bottle Packaging: A UK Guide

For a UK juice bar, cold-press line or grab-and-go fridge, PET bottles are the format that turns a made-to-order drink into a product you can batch, chill and sell off a shelf. Three sizes cover almost everything — 250ml for shots and small servings, 330ml for a standard juice or smoothie, 500ml for a larger pressed juice or cold brew. Add a tamper-evident cap so the seal is visible, and the drink reads as fresh, safe and premium before anyone reads the label.

Below: the sizing, caps, clarity, labelling and recyclability decisions that make a bottled juice range work, plus when a bottle beats a cup and when it doesn't.

Why PET bottles for juices and smoothies

A lidded cup is made to be handed over and drunk. A bottle is made to be sealed, stacked and stored — which is a different job. Once a drink is capped in PET it travels without spilling, holds its look in a chiller, and lets a customer buy now and drink later. That single difference is what lets you batch cold-press juices ahead of the morning rush instead of pressing every order to order.

PET earns its place here on clarity and strength. It's rigid, crystal-clear and handles condensation without going soft, so a green juice or a layered smoothie shows clean through the wall of the bottle. For anything where the colour of the drink is part of the sell, that visibility is the point.

If you're weighing bottles against cups for the same menu, our cold drinks and smoothie packaging guide covers the cup side in full — this piece stays on bottles.

PET bottle sizes: 250ml, 330ml, 500ml

Keep the range tight. Most juice menus run well on two or three sizes, and every extra size is more stock to hold and more label artwork to manage.

• 250ml — wellness shots, ginger or turmeric shots, kids' portions, and small tasters. Small enough to price as an impulse add-on at the till.
• 330ml — the workhorse. A standard cold-press juice or a single smoothie serving. This is the size most grab-and-go fridges are built around.
• 500ml — larger pressed juices, cold brew coffee, and value or sharing portions. Right where the customer wants more volume for a higher price point.

Match the size to the portion and the price, not to what looks generous. An overfilled 500ml that you're selling at a 330ml price quietly erodes margin on every unit. Our whole juice bottles range is built around these three so caps and labels carry across sizes.

Tamper-evident caps: the trust signal

The cap does more than stop spills. A tamper-evident cap has a ring that breaks the first time the bottle is opened, so a customer can see the seal is intact when they pick it up and see it's been broken once they've opened it. For chilled juices sold off an open shelf, that visible first-open seal is a real reassurance — it says the bottle hasn't been touched since it left your prep area.

A few practical points:

• Keep to one neck size across your bottle range so a single cap fits every size. It simplifies ordering and means you're never caught short of caps for one bottle but not another.
• Cap on cleanly and check the seal before the bottle goes in the chiller. A cap that's cross-threaded won't tamper-evidence properly.
• For shots, a smaller cap on the 250ml is fine, but if you can run one neck size across all three, do — it's less to think about.

Clarity and shelf appeal

A chilled bottle is merchandising as much as packaging. Line a fridge with clear PET and the drinks sell themselves — the customer reads the colour, sees the freshness and reaches in. That's the argument for paying for good clarity rather than a cloudy budget bottle: on an open shelf, the drink is the advert.

Two things protect that look. Fill consistently, so every bottle in the row sits at the same level — a mismatched fill line reads as careless. And keep labels clean and low on the bottle so the drink itself stays visible above the label. The bottle is a window; don't paper over it.

Labelling: what to put on a bottle

Once you're selling a sealed, pre-made drink off a shelf rather than handing over a fresh cup, labelling matters more. A grab-and-go bottle is prepacked food, and prepacked food carries labelling duties — ingredients, allergens and dating among them — that a made-to-order cup doesn't.

The rules here are not something to eyeball. Check the current requirements on gov.uk and your local authority's food standards guidance, especially around allergen labelling and date marking for drinks made and packed on the same premises versus packed for direct sale. The safe stance is to confirm what applies to your setup before you print a run of labels, not after.

Practically, keep label artwork sized to your chosen bottles so one design scales across the range, and leave the drink visible above it.

Bottle or cup: choosing the format

Some drinks want a bottle, some want a cup, and a few sell either way. The split comes down to how the drink is made and how it's sold.

Read it this way: if the drink is batched ahead, sold from a chiller, and might be carried home, it's a bottle. If it's pressed or blended to order and drunk straight away, it's a cup — and the cold cups range with matched dome and flat lids is where that lives. Plenty of sites run both: bottles in the fridge for grab-and-go, cups at the counter for made-to-order.

Recyclability of PET, honestly

PET is one of the more widely recycled plastics in the UK, and clear PET bottles are among the easiest items for kerbside collection to handle. That's a fair thing to tell a customer. What isn't fair is implying a bottle will definitely be recycled — that depends on the customer rinsing it, putting it in the right bin, and their local council actually accepting it, and collection rules vary from one authority to the next.

So keep the claim honest: PET is widely recyclable, and customers should check their local council's kerbside guidance. Caps and labels can complicate recycling too, so the plain, defensible line is the best one — no overclaiming, no recycling logos you can't stand behind. If you want a broader honest read on eco materials and disposal, our team keeps that conversation grounded in the same place: local guidance over marketing language.

Cold-hold and grab-and-go display

Bottled juice lives or dies in the chiller. Keep it cold-held at the correct temperature, rotate stock so the oldest bottles sell first, and date every batch — which loops back to labelling above. A tidy, well-lit, front-faced fridge of clear bottles at consistent fill levels is one of the best passive sellers a juice bar has. Batch ahead, seal, chill, face the labels forward, and let the shelf do the work.

Ready to stock your juice range

Build your bottled line from the juice bottles range in 250ml, 330ml and 500ml with matched tamper-evident caps, and keep the cold cups range alongside for made-to-order drinks.
