Fresh berries warm quickly
Warm fruit adds heat load and shortens shelf life. Finished product should enter the shipper already chilled.
Chocolate-Covered Strawberries
Cold Chain Packout for Fresh Fruit, Chocolate Shell, and Gift Presentation
Chocolate-covered strawberries need a chilled route, but the packout cannot treat them like normal chocolate or normal fruit. The goal is to hold the berries cold, keep the shell dry, protect the clamshell, and avoid direct coolant pressure.
2-8 جTypical chilled route target after validation
12-36 حCommon bakery, هدية, and DTC delivery window
Dry shellChocolate surface and clamshell should not collect condensation
No freeze contactCoolant must be buffered away from fruit and chocolate
Product Risk
Why this product needs a different packout
A standard ice pack box can keep the shipment cold, but it can still fail if the clamshell gets wet, berries soften, chocolate cracks, or the tray is pressed by frozen gel packs. The package has to control temperature and presentation at the same time.
Condensation can ruin appearance
Wet clamshells, تسميات, and chocolate surfaces create the look of poor handling even when the product is still cold.
Frozen packs can damage shells
Hard gel packs placed directly on top can crack coating, flatten toppings, or deform the clamshell lid.
Quality is judged visually
The receiver checks shine, جفاف, tray position, fruit firmness, and package cleanliness before temperature data.
Route-Based Recommendation
Choose the packout by ambient condition and delivery time
These are practical starting points for sample design. The final gel pack weight, سمك العزل, and placement should be verified with a route test.
| Shipment condition | Recommended Tempk package | Starting coolant direction | موقف المبرد | ما للتحقق من صحة |
|---|---|---|---|---|
| Same-day local delivery 8-18ح الطريق, ambient below 22 ج, short handoff time |
Insulated carton liner or compact EPS shipper, rigid clamshell tray, وسادة ماصة, dry liner bag | Small parcel starting point: عن 0.4-0.8 kg total conditioned gel ice packs for a 1-3 kg chilled payload. Use the calculator for the actual box size and route time. | Side wall or top corner with corrugated divider; no direct contact with clamshell lid | Arrival temperature, clamshell dryness, chocolate shine, tray movement, and remaining coolant state |
| Overnight parcel route 18-36ح الطريق, المحيط 22-30 ج, depot and van exposure |
EPP or EPS insulated box, حقيبة بطانة, طبقة ماصة, rigid product spacer, outer carton protection | Sample design range: عن 0.8-1.5 kg total gel ice packs or chilled PCM for a small parcel. Select coolant by target range, كتلة الحمولة, ومستوى العزل. | Two side positions or side-plus-top with buffer layer; logger near product, not against coolant | تتبع درجة الحرارة, condensation points, top pressure, fruit firmness, shell cracks, and label condition |
| Hot-weather or delay-prone route 30-35 C ambient, 36-48h risk, weekend hold possible |
Thicker EPP/EPS shipper, higher insulation margin, حاجز الرطوبة, stronger outer carton, route logger | Test-first range: عن 1.5-2.5 kg total coolant or a PCM system for a small parcel. Ice bricks can be considered only with full buffering and cold-spot testing. | Perimeter coolant layout with divider on all product-facing sides; keep weight off the clamshell top | Warmest internal point, cold spot risk, condensation recovery, receiving appearance, and route delay margin |
Coolant mass is a starting point, ليس ضمانا. Adjust by payload weight, clamshell count, حجم الشاحن, مادة عازلة, تكييف المبرد, مدة الطريق, ملف تعريف المحيط, ومعايير الاستلام. More ice does not solve cracked shells, التسميات الرطبة, or crushed trays if the product support and moisture barrier are wrong.

Packout Structure
Build the box from the product outward
For chocolate-covered strawberries, the inner product support is as important as the insulation. A good packout protects the berries from cold shock, tray movement, and moisture before it tries to extend route duration.
Recommended layer order
1. Product trayRigid clamshell or tray with enough headspace for toppings and chocolate shell clearance.
2. طبقة ماصةPad or sheet below the clamshell area to manage light condensation or berry moisture.
3. Dry barrierLiner bag or moisture sleeve to keep paper labels and retail packaging dry.
4. Coolant dividerالمموج, رغوة, or molded spacer between gel packs and product.
5. الشاحن المعزولإي بي بي, EPS, or insulated carton selected by route time, النطاق المحيط, and payload count.
6. موقف المسجلNear the product center or warm side, never taped directly to a gel pack.
عملية التعبئة
قبل التبريد, متفرق, ثم التحقق
This product should not be packed warm and rescued with extra ice. The best result comes from controlling product temperature before packing and using a buffered coolant layout.
1
Chill the finished product first
Move finished trays into a controlled chilled room before packing so the strawberries and chocolate shell start cold and stable.
2
Condition gel packs before use
Use the selected gel pack or PCM condition based on the tested route. Do not place hard-frozen packs directly against fruit or clamshells.
3
Pack product level and supported
Keep clamshells level, تقليل المساحة الفارغة, and prevent top-load pressure from coolant or mixed items.
4
Check arrival beyond temperature
سجل درجة الحرارة, but also inspect shell shine, تشققات, clamshell dryness, fruit firmness, حالة التسمية, and tray movement.
When to Change the Design
Signals that the packout needs adjustment
If the product arrives cold but wet
Keep the same thermal target, then improve barrier layers, مادة ماصة, ventilation gap, or coolant conditioning.
If the shell cracks or toppings shift
Reduce top pressure, move coolant to side pockets, add a product spacer, and check clamshell headspace.
If the warmest product exceeds target
Increase insulation margin, adjust coolant mass, shorten route time, or move to an EPP/EPS shipper for the season.
