The real headache with freezing smoothies isn’t the recipe — it’s opening the freezer to find a cracked jar, a sticky puddle, or a block of ice you can’t pry out. The right container turns a frozen smoothie into a grab-and-go breakfast instead of a cracked jar or sticky puddle.
I’m Mohammad Maruf — the founder and writer behind WellFizz. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Whether you prefer leak-proof plastic portion cups or heavy-duty glass bottles with protective sleeves, these seven picks cover every budget and habit for the best containers for freezing smoothies.

How To Choose The Best Containers For Freezing Smoothies
When you freeze a smoothie, you are asking a container to handle expansion, hold a seal at sub-zero temps, and still feel easy to handle in the morning. Here is what matters when choosing a container for freezing smoothies.
Material: Glass vs. Plastic
Glass won’t absorb odors or stain over time, but it can crack if you overfill. Look for thick-walled glass or glass with a silicone sleeve for protection. Plastic is lighter and drop-proof; the premium choice is Tritan, a BPA-free plastic that stays clear and survives freezer duty for years.
Size and Shape
16 oz is the classic single-smoothie size; 8 oz works for smaller portions or kid servings. Round containers are easiest to twist open, while square bottles maximize freezer space. A wide mouth (2 inches or more) makes filling, stirring, and cleaning much easier.
Seal and Lid Type
An airtight, leak-proof lid is non-negotiable for freezing. Screw-on and twist-top designs generally seal better than snap-on lids. Look for lids with a rubber or silicone gasket for the best airtightness and least chance of a spill.

In‑Depth Reviews
1. Bentgo Prep – 20 Piece 16 fl oz Leak-Proof Deli Containers with Lids
The pro-grade deli container set built to survive a full week of freezing, microwaving, and dishwashing.
This 20-piece kit from Bentgo gives you ten 16 fl oz round containers and ten twist-top lids. Take the guesswork out of portioning — each container holds a single smoothie serving, and the cylinders are nestable, so you save space when not in use. The real win here is the lid: a twisted seal that buyers call “leak-proof” and “very sturdy,” so you can stack these in the freezer without a second thought.
At 0.59 kilograms for the set, these are noticeably heavier than basic deli cups, which directly translates to the thick, crack-resistant plastic that reviewers praise. One owner noted they are “better than other brands” and survived the dishwasher without warping. Unlike the glass options below, these drop-safely if you fumble a frozen block. The one honest trade-off? Some buyers felt the price per container was a hair high compared to generic cups, but the durability more than makes up for it long-term.
Bentgo’s containers are free of PFAS and BPA (so no chemical worries), microwave-safe with the lid off, and stack neatly in both fridge and freezer.
Meal prep deli set
- Thick, sturdy plastic resists cracking and freezer warping
- Leak-proof twist-top lids keep frozen smoothies sealed tight
- Dishwasher, microwave, and freezer safe — truly all-in-one
Lids may loosen
- Pricier per container than some basic plastic sets
- Cylinder shape won’t maximize space like square bottles
Portion control: you want a bomb-proof, stackable, no-nonsense deli container that handles daily freezing and reheating without degrading.
Frequent travel: you prefer glass or need square bottles that pack tighter.
2. Gemice 6-Pack 16 oz Overnight Oats Containers with Lids and Silicone Sleeves
Glass jars wrapped in colorful silicone armor for shock absorption and a non-slip grip.
Each jar in this 6-pack holds 16 ounces and comes with a silicone sleeve that absorbs drop shock and prevents bottles from clinking together in the fridge. The twist-on lids have a built-in silicone gasket for an airtight seal, and the set includes two extra spare gaskets for long-term maintenance. The wide mouth makes it easy to pour a frozen smoothie block into a blender or scoop out chia pudding.
Buyers confirm these jars are “sturdy 16oz glass” with airtight lids that don’t leak — one noted the silicone sleeve “prevents clinking” and eliminates worry about microplastics. This is a clear step up from the DRKIO and STARSIDE glass sets because the protective sleeve addresses the main weakness of bare glass: impact breakage. All components are top-rack dishwasher safe, though reviewers recommend hand-washing the lids to preserve the gasket seal. The sleeves also add a visual pop to your freezer shelf.
Breakfast prep: anyone who wants glass safety (no odor, no stain) but doesn’t want to worry about chips or cracks every time they stack jars.
Hot liquids: bulk is a concern — these are heavier than plastic, and the sleeves add a bit of width.
3. DRKIO 16 Oz Overnight Oats Containers with Lids – 4 Pack Glass Storage Jars
Straightforward 16-ounce glass jars with a recessed, stackable lid design for neat freezing.
These four jars are each 16 ounces (473 ml) by volume and measure 3.3 x 3.3 x 4.7 inches — a classic mason-style shape that stacks stably. The lids include a thin rubber seal that buyers report keeps food “air tight” for overnight oats. One buyer’s tip: after washing, push the thin rubber seals down into the lid firmly for the best seal. The textured lids help your grip when twisting open a frozen jar, and the recessed top allows you to stack another jar right on top without wobbling.
This is a no-frills glass option compared to the Gemice set above — you don’t get silicone sleeves or spare gaskets, so handle with care. A few reviewers did report that the seals “sometimes tend to leak out if they don’t get properly sealed,” so check the seal each time you close one up for the freezer. At this price point for a 4-pack, it’s a lean entry into glass storage.
Slim 16oz containers
- Durable thick glass that survives dishwashers and freezers
- Recessed lid design for stable stacking
- Comes with a whiteboard marker for labeling
Lids not leakproof
- Rubber seal may leak if not seated correctly
- Only 4 jars — fewer than other multi-packs at similar cost
Smoothie storage: you want a simple, dishwasher-safe glass jar for overnight oats and individual smoothie preps.
Soups: you have a big family or want extra protection from breakage (look at the Gemice set with sleeves).
4. AOZITA 12 Pack 16 oz Glass Juice Bottles with Airtight Lids & 2 Straw Lids & 2 Straws
A massive 12-pack of 16 oz glass bottles that come with straws, straw lids, and labels — ready for bulk prep.
This set from AOZITA includes 12 glass bottles, each holding 16 fluid ounces (480 ml). The tall shape (2.7″ wide, 6.8″ tall) fits into most car cup holders, and the wide mouth makes filling easy. The airtight lids are lined with a thin sheet of foam to keep smoothies fresh and leak-free, and the bonus two lids with straw holes and two stainless steel straws are a nice touch for drinking straight from the bottle after thawing. Each bottle comes with a white label for marking contents and dates.
Reviewers confirm these are “high-quality glass jars” that “protect juice better and longer than plastic.” One buyer appreciated that the set includes a straw brush for easy cleaning. The main difference between this and the Gemice set is the lack of silicone sleeves — these are bare glass, so you’ll want to handle them carefully when frozen. The 12-count is great for weekly meal-preppers who want to fill a whole shelf at once.
Cold drinks: batch-freezing a whole week’s worth of smoothies or juices — the 12-count and straw lids make it a complete system.
Freezer use: those who dislike tall bottles or need a wider mouth for easy scooping.
5. STARSIDE 8 oz Glass Juice Bottles with Lids 6 Pack
Thick-walled 8 oz square bottles that survived a drop full of juice, according to buyers.
If you want petite containers for kid-sized smoothies or concentrated juice shots, these STARSIDE bottles deliver. Each bottle holds 8 fluid ounces and measures 2.1 inches wide by 5.3 inches tall — a square profile that nests together to save freezer space. The glass is noticeably thick: one reviewer noted the bottle “survived drop full of juice without breaking.” The set includes 6 color-coded labels, one soft sponge brush, and BPA-free plastic lids that seal leak-proof.
At 1.23 kilograms, this 6-pack is almost 4.4x heavier than the TOFLEN 0.28 kg plastic containers — a direct result of that thick-walled glass. That heft gives you confidence in daily use, but it also means a full freezer shelf will be noticeably heavier. The manufacturer recommends a 5-6 oz fill level for freezing to allow for liquid expansion, so don’t fill right to the brim.
Small 8oz glass
- Thick, premium glass that resists breakage
- Square shape maximizes freezer storage
- Includes brush for easy cleaning
Lid seal weak
- 8 oz is small — not enough for a full adult smoothie
- Very heavy for its size (1.23 kg per set)
Dressings: juices, concentrated smoothie bases, or small portions — the square shape is a space saver.
Large portions: large single-serve smoothies; you will need multiple bottles per serving.
6. TOFLEN Reusable Small Freezer Containers 8 Oz Plastic Food Storage Containers, Set of 12
12 lightweight 8 oz plastic containers that are more than just budget-friendly — they actually work.
This set from TOFLEN gives you 12 round containers with colored screw-on lids (4 red, 4 green, 4 yellow). Each holds 8 fluid ounces, and the lids create an airtight space that owners mention “works well and is easy to remove even when frozen.” One buyer mentioned they are the “perfect single-serving size for freezing homemade dog food,” which tells you the seal is solid enough for wet, messy contents. At just 0.28 kilograms per set, these are featherweight compared to the STARSIDE glass set (which is 1.23 kg — about 4.4x heavier).
The PP plastic is BPA-free, microwave-safe, and freezer-safe. The concave lid design lets you stack them neatly without toppling. A few buyers mentioned they were “really hard to unstack at first, but much easier after washing,” so give them an initial rinse before stacking. These are not as premium-feeling as the Bentgo containers above — the plastic is thinner — but they are a honest value for the price.
Leftovers: starting out on a tight budget or needing a high quantity of small containers for portioned freezing.
Hot fill: the plastic is lighter duty than the Bentgo set — expect shorter overall lifespan with heavy daily use.
7. Komax Reusable Juice Bottles, Set of 6 – 18.5 oz Premium BPA-Free Plastic
The 18.5 oz Tritan plastic bottle that delivers glass-like clarity with shatterproof toughness.
Komax uses Tritan, a premium BPA-free plastic that stays crisp in the freezer and feels sturdy without the weight of glass. Each bottle holds 18.5 ounces — the largest capacity in this list — so you get a generous smoothie serving. The wide mouth is 2.1 inches across, making it easy to fill with frozen fruit and pour thawed smoothies straight into a blender. The leak-proof lid has an inner cap that makes drinking with a straw spill-proof, keeping the seal tight during thawing.
At 0.62 kilograms for the 6-pack, these are lighter than glass but still feel substantial. Customers note they are “high quality, durable, and last for years” even with regular freezer use. One reviewer specifically uses them for freezing milk and juice, noting that they “thaw in the fridge in about a day.” The one feature these miss that the Bentgo set offers is microwaveability — Tritan is generally not microwave-safe, so use them strictly for storage and freezing.
Premium juice set
- Tritan plastic is shatterproof and freezer-durable for years
- 18.5 oz holds more than any other pick here
- Wide mouth (2.1″) for easy filling and cleaning
Glass break risk
- Not microwave-safe — reheat only after transferring contents
- Taller shape (8.2″) may not fit compact freezer shelves
Daily juice: you want the largest shatterproof freeze-and-go bottle with decades-long brand trust in Tritan.
Kids use: heating leftover smoothie directly in the container is a must for you.
Understanding the Specs
Headroom for Freezing
When a smoothie freezes, its volume expands. If you fill a container to the brim, you risk bulging lids or cracked glass. The general rule is to leave about ½ to 1 inch of headspace at the top — that is the empty gap between the liquid surface and the lid. The STARSIDE bottle manual recommends a 5-6 oz fill in an 8 oz bottle specifically to “prevent liquid expansion.”
Airtightness vs. Leak-Proof
An airtight container keeps freezer burn out by preventing air from circulating around your smoothie. A leak-proof lid ensures nothing drips from the container when thawing. These are related but not the same — a snap-on lid might be leak-proof upright but not airtight. For freezing smoothies, you want a screw-on or twist-top lid with a silicone or foam gasket. That combination is what the Bentgo, Gemice, and AOZITA sets all provide.
