Estimate coolant mass
Use payload weight, route time, box size, and seasonal ambient temperature before ordering the first test packout.
Premium steak route
Steaks Cold Chain Packaging Solution
Steak shipments need a clear route decision before packaging is chosen: chilled presentation, deeply chilled delivery, or frozen DTC delivery. The packout should protect color, texture, vacuum or tray integrity, and purge control while keeping coolant from marking the steak surface.
Temperature intentUse 0-2 C for premium chilled steak presentation when required, 0-4 C where the food safety program allows, and -18 C or below for frozen steak routes.
Moisture controlUse primary sealing, liner protection, and absorbent material based on product purge and route handling.
Coolant ruleDo not use the same packout for chilled retail steaks and frozen DTC steak boxes. Chilled routes use separated gel packs or 0 C PCM; frozen routes usually need dry ice planning and carrier checks.
Receiving checkConfirm temperature, leakage, label condition, coolant position, and product surface quality together.
Choose the packout by route condition
The coolant amounts below are starting ranges for planning. Final packout should be validated with the exact payload, box size, carrier lane, and season.
| Route condition | Temperature intent | Tempk packaging setup | Coolant planning range | Coolant position |
|---|---|---|---|---|
| Premium chilled sample, 8-18 h | 0-2 C chilled presentation | EPP box or insulated carton, vacuum/tray pack, absorbent layer, leak liner. | 0.8-1.5 kg conditioned gel packs or 0 C PCM for 1-4 kg payload. | Side and top coolant with divider; keep frozen packs off the steak face. |
| Overnight chilled parcel, 18-36 h | 0-2 C or 0-4 C by program | Thicker insulation, reduced headspace, sealed liner, logger in product air space. | 1.5-2.8 kg gel packs or PCM for 1-4 kg payload. | Perimeter coolant plus separated top layer; prevent tray dents and vacuum seal pressure. |
| Hot lane or 36-48 h chilled test | Validated chilled lane | Pre-qualified box size, stronger insulation, service-level check. | 2.8-4.5 kg gel packs or PCM for 1-4 kg payload. | If direct freeze marks appear, improve separation before adding more coolant. |
| Frozen DTC steak route | -18 C or below | Frozen shipper, dry ice plan, vapor gap, label and carrier check. | Use the dry ice calculator by box size, payload, and route duration. | Keep dry ice separated and meet carrier marking rules. |
For a tighter first estimate, use the Ice Pack Calculator. If the route is frozen, compare with the Dry Ice Calculator before testing.
Packout sequence that protects meat quality
The right sequence reduces warm dwell, leakage, coolant contact, and pack damage before the box reaches the receiver.
1
Decide chilled or frozen first
Chilled steaks need controlled cooling without freeze contact. Frozen steaks need a dry ice or frozen-coolant route that protects against thaw.
2
Pre-cool meat and shipper parts
Warm liners, trays, or cartons can consume coolant before the box leaves the origin.
3
Control purge and presentation
Use absorbent layers and leak liners so the receiver sees a clean pack, dry label, and intact vacuum or tray seal.
4
Validate by quality, not temperature alone
Check product temperature, color, purge, vacuum integrity, tray dents, and any coolant contact marks.
Common losses this packout is meant to prevent
Use these receiving checks when deciding whether to adjust coolant mass, liner structure, or insulation thickness.
Quality and packaging risks
- Brown or dull surface color from warm dwell or poor insulation.
- Freeze marks from gel packs or dry ice placed too close to the steak surface.
- Purge leakage into the shipper or outer carton.
- Vacuum seal stress or tray dents from heavy top-loaded coolant.
Tools, components, and related routes
Use the product page for the handling logic, then size the first trial with tools and validate the real route.
Choose the coolant family
Compare conditioned gel packs, 0 C PCM, and frozen-route dry ice logic before changing insulation size.
Check route risk
Review pickup dwell, last-mile delay, receiving window, and season before launching a meat route.
