How to use ice gel packs correctly is the difference between products arriving perfectly chilled and arriving spoiled. Gel packs only protect your shipment if you prepare and pack them the right way — how long to freeze them, how many to use per box, where to position them, and how to reuse them. This guide walks you through the process, step by step.
How to Use Ice Gel Packs: Step 1 — Freeze Them Fully
The most common mistake is using packs that are only half frozen. For best results, lay your gel packs flat in a freezer for about 24 hours before you need them. They should feel rock solid all the way through, with no soft or slushy spots. A fully charged pack holds cold far longer than one that was only frozen for a few hours.
Freeze packs flat rather than folded — a flat pack freezes evenly and sits neatly against the box walls. If you ship regularly, keep a rotation: one set freezing while another is out on deliveries.
How to Use Ice Gel Packs: Step 2 — Pack the Box in the Right Order
Packing order matters because cold air sinks. Follow this sequence:
- Pre-chill the box. If possible, keep your insulated Thermopore box in a cool place before packing. A warm box melts your packs faster.
- Place the products first. Put your chilled or frozen goods in the centre of the box.
- Put gel packs on top and along the sides. Cold sinks downward, so packs on top cool everything below them. Packs along the sides surround the products with cold air.
- Fill the air gaps. Empty space lets warm air circulate. Fill gaps with crumpled paper or extra insulation so the cold stays where it belongs.
- Seal the box quickly. Tape it shut and keep it out of direct sunlight until dispatch.
Step 3 — Use the Right Number of Gel Packs
There is no single magic number — it depends on box size, outside temperature, and journey length. A small cooler for a few hours needs fewer packs than a large Thermopore box on an intercity route, and hotter weather needs more packs.
For regular shipments, run a test: pack a box the way you plan to ship it, leave it for the expected journey time, and check the internal temperature. Add packs until the temperature holds. Our team can also advise on quantities — message us on WhatsApp at 0311-8140910.
Step 4 — Reuse and Store Your Gel Packs
After delivery, wipe the packs clean, check for punctures or leaks, and refreeze them flat. A quality gel pack survives many freeze-thaw cycles. Discard any leaking or damaged pack — never use a torn pack with food.
Between uses, store packs flat in the freezer so they are always ready, or at room temperature in a clean, dry place if freezer space is tight.
Common Mistakes to Avoid
- Using half-frozen packs — always freeze until rock solid.
- Too few packs for the box size — when in doubt, add one more.
- Packs only at the bottom — cold sinks, so top placement matters most.
- Leaving the sealed box in the sun — even the best packing cannot beat direct sunlight for hours.

FAQs on How to Use Ice Gel Packs
How long should I freeze gel packs before first use?
Freeze them flat for about 24 hours until completely solid. Shorter freezing gives shorter cooling time, so a full day in the freezer is the safest approach.
Can you refreeze and reuse gel packs?
Yes. Wipe them clean, inspect for damage, and refreeze flat. Quality packs handle many cycles. Replace any pack that leaks.
Where exactly should gel packs go inside the box?
Place them on top of the products and along the sides. Cold air sinks, so top placement cools everything below, and side packs surround the goods with cold.
How should I store gel packs between shipments?
Keep them flat in the freezer so they stay charged and ready, or in a clean, dry place at room temperature if you are short on freezer space.
