Freeze-Dried Strawberries: Shelf Life, Packaging and Container Loading
Freeze-dried strawberries keep 12 months at ≤25 °C and RH ≤60%, and 18–24 months in cool storage at ≤18 °C and RH ≤50%, in the unopened bag. FruitBuys Vietnam packs them in 1–5 kg aluminium-foil bags with silica gel, in 5-ply cartons, and floor-loads about 550 cartons per 20ft in a standard dry container.
Everything about the pack has one job: keep the strawberry as crisp and red as it was when it left the dryer, from the partner facility in Vietnam to your production line or your shelf. This guide covers how long the fruit keeps and why, the bulk and retail packs, storage after opening, carton and pallet patterns, and how much fits in each container. The buying guide is freeze-dried strawberries in bulk.

How long do freeze-dried strawberries last?
12 months at ambient (≤25 °C, RH ≤60%) and 18–24 months in cool storage (≤18 °C, RH ≤50%), sealed in the original bag. Powder keeps for the same periods in its 5 kg foil bags.
Shelf life here is a quality window, not a safety deadline. At water activity ≤0.30, nothing can grow in the bag, so a sealed, dry freeze-dried strawberry does not spoil the way fresh fruit does. What changes slowly over time is quality:
- Crunch, if moisture gets in: the pieces turn leathery and powder cakes.
- Colour, if light and oxygen get in: the red fades toward dull pink.
- Aroma, gradually, faster at higher temperature.
The pack keeps all three out, and the storage conditions set the pace. Use the two windows as a planning tool: a distributor buying a dry-season container to sell through the year holds stock cool for 18–24 months; a brand turning stock in a few months stores at ambient. For a private-label product with a long printed date, an accelerated shelf-life study on the final retail pack confirms the date for that pack.
What is in a bulk pack, and why no nitrogen?
| Layer | Specification | What it does for you |
|---|---|---|
| Bulk bag | 1–5 kg, PET/AL/LLDPE laminate with a true aluminium-foil layer | Near-zero light, oxygen and moisture transmission: colour and crunch stay in |
| Inside the bag | Food-grade silica gel desiccant in a dust-proof sachet | Takes up any trace moisture after sealing |
| Bag atmosphere | Soft vacuum, no nitrogen flush | Pieces held still at sea; a flat bag that fits the carton |
| Carton | 5-ply, 58 × 28 × 34 cm | Stacking strength for seven layers |
Why foil. The red is anthocyanin, the strawberry’s own pigment, and it fades with light. A true aluminium-foil layer keeps the colour you approved on the sample through the voyage and through months in your warehouse.
Why no nitrogen in bulk. A nitrogen-flushed bag is a pillow: it takes more room, so fewer kilos fit per carton and per container, and a 5 kg pillow squeezed into a carton can crack the foil at the seams. A soft vacuum draws the bag gently around the fruit so pieces cannot rattle, and the bag lies flat. Moisture is the real enemy of a freeze-dried strawberry, so the silica gel does the protective work and the vacuum does the logistics.
Why desiccant, not oxygen absorbers. Common iron-based oxygen absorbers need moisture to react, which works against a desiccant in the same bag and against a product kept at aw ≤0.30. FruitBuys uses silica gel only, and never iron-based absorbers in powder.
What retail and private-label packs are available?
| Pack | Typical use | Notes |
|---|---|---|
| Stand-up zip pouch, 15–50 g | Snack pouches, single servings | Full foil or high-barrier window |
| Foil zip pouch, 100–500 g | Family packs, foodservice, e-commerce | Full foil for longest shelf life |
| Window pouch | Retail where the red berry sells the pack | High-barrier coated film (PVDC-coated or AlOx/SiOx-coated), not plain PET |
| Stick packs and sachets | Powder for drinks and premixes | One dose per pack |
Retail pouches are sealed in a dehumidified packing room at the source, with an optional light nitrogen flush for whole berries as a cushion on the shelf; in a small retail pouch, that cushion protects the shape, while in bulk the soft vacuum wins. Print runs: digital from 3,000–5,000 pouches per SKU in 7–10 working days with no cylinder costs, or rotogravure from 500 kg per SKU in 15–20 working days at the lowest cost per pouch. Pouch films, label data and the EU packaging rules that apply from August 2026 are covered in private-label freeze-dried strawberries.

How should freeze-dried strawberries be stored, before and after opening?
Before opening: cartons sealed, off the floor, in a dry store at ≤25 °C and RH ≤60%, away from sunlit walls, steam, ovens and strong odours. For stock that has to last more than a year, a cool store at ≤18 °C and RH ≤50% extends the window to 18–24 months.
After opening: the fruit starts drawing moisture from the air within minutes, so the rule is simple: open a bag, use the whole bag. That is why bulk bags are 1–5 kg, sized to one production batch, and powder comes in 5 kg bags. If a bag must be part-used, press out the air, reseal it with its desiccant sachet and use it within about two weeks. In a humid kitchen or bakehouse, keep open bags away from dishwashers and proofers.
Which carton sizes and pallet patterns are used?
One carton size for every format, 58 × 28 × 34 cm, so mixed loads stack in straight columns:
| Format | Net per carton | Why that weight |
|---|---|---|
| Whole and halves | 6 kg | Lighter load protects the bottom layer from crushing |
| Slices | 7 kg | Flat pieces stack tighter |
| Dice and crumble | 10 kg (22 lb) | Fills the carton; the 22 lb case many US buyers expect |
| Powder | 20 kg (4 × 5 kg bags) | Dense product |
Pallets: on a standard 1.2 × 1.0 m pallet, cartons stack 6 per layer, 4 layers high, about 24 cartons: roughly 145 kg of whole berries, 170 kg of slices or 240 kg of dice. That is also the trial order: one pallet. A palletised 20ft carries about 240 cartons.
How much fits in a 20ft and a 40ft HC?
| Format | 20ft, floor-loaded (about 550 cartons) | 40ft HC, floor-loaded (about 1,100 cartons) |
|---|---|---|
| Whole, halves | about 3.3 t | about 6.6 t |
| Slices | 3.85 t | 7.7 t |
| Dice, crumble | 5.5 t | 11 t |
| Powder | about 11 t | Mixed loads (powder alone ships in 20ft for road weight) |
Floor-loading puts cartons lengthwise in straight columns, 8 across and 10 deep, 7 layers high: about 550–560 cartons in a 20ft, against about 240 on pallets. Freight per kilo falls by roughly 56%. A 6-layer load (about 480 cartons) leaves roof clearance where an insurer asks for it. If your warehouse accepts pallets only, the extra freight buys a faster unload; many buyers floor-load and palletise at their own dock.
Mixed loads: a 40ft HC can carry about 250 cartons of powder (5 t) on the floor and about 850 cartons of slices (about 6 t) above, close to 11 t, so one booking feeds two lines. Strawberries can also share a container with other FruitBuys freeze-dried fruits on the same carton standard, which typically cuts logistics cost per kilo by around 15–20% against separate LCL lots.
Freight per kg = container freight ÷ net kg loaded. Put your forwarder’s rate into that line for each format; dice ship at about 40% less freight per kilo than whole berries. The full cost picture is in why are freeze-dried strawberries so expensive?
Do freeze-dried strawberries need a reefer?
No. At water activity ≤0.30 they ship in a standard dry container, which keeps freight and booking simple and removes the cold-chain risk that fresh and frozen fruit carry. Two route conditions are worth planning for:
- Container rain. A container stuffed in humid southern Vietnam and cooled at sea can drip condensation from the roof. FruitBuys loads seven full layers on a dry floor, lines the walls with kraft paper, covers the top layer so any drips land on the cover, and fits container desiccant poles on request for rainy-season sailings and long routes.
- Port heat and inspection. Sealed, opaque, desiccated bags hold the red through a normal transit, including a few days in a summer terminal. If customs opens cartons for sampling, ask your broker to reseal them or use those bags first.
Within 48–72 hours of devanning, photograph the container as found, open two or three sealed bags from different rows, snap a slice within 60 seconds and read water activity against ≤0.30. That record, with the retained sample FruitBuys keeps from every container lot, settles any transit question quickly. The full arrival check and limits are in freeze-dried strawberry specs: moisture, aw and COA.
Which pack and load fit your operation?
| Your situation | Pack and load |

FAQ
Can freeze-dried strawberries go bad?
Sealed and dry, they do not spoil, because nothing can grow at water activity ≤0.30. Over time they can lose crunch if moisture gets in and colour if light gets in. Unopened in foil with a desiccant, they keep 12 months at ≤25 °C or 18–24 months in cool storage at ≤18 °C.
How long does freeze-dried strawberry powder last?
The same as the pieces: 12 months at ≤25 °C and RH ≤60%, and 18–24 months at ≤18 °C and RH ≤50%, in the sealed 5 kg foil bag. Powder draws moisture faster once open, so open one bag per batch in a room below 40% RH.
Do you sell 22 lb bulk cartons?
Yes. Diced and crumble freeze-dried strawberries ship in 10 kg (22 lb) cartons. Whole berries pack at 6 kg and slices at 7 kg per carton to protect the bottom layer; powder packs at 20 kg as four 5 kg bags.
How should freeze-dried strawberries be stored after opening?
Use the whole bag in one batch where possible. If not, press out the air, reseal with the desiccant sachet, keep it in a dry, cool place away from steam and use within about two weeks.
How many kg of freeze-dried strawberries fit in a 40-ft container?
A 40ft HC holds about 1,100 cartons floor-loaded: about 6.6 t of whole berries, 7.7 t of slices or 11 t of dice. Powder and slices can share a 40ft HC at close to 11 t in total.
