Compact 400ml water injection pack for small chilled parcels

The 400ml reusable water injection ice pack is a compact option for small parcels and delivery bags. It stores flat before water filling, freezes after activation and can be placed around food, pharmacy items or chilled products in a controlled packout.

Compact 400ml format

The size fits small cooler bags, food boxes and parcel cartons where large bricks are too bulky.

Light before filling

The empty pack reduces inbound transport weight and storage space before activation.

Reusable cold pack option

Can be refrozen and reused within its service life when the bag and valve remain intact.

Good for delivery workflows

Suitable for grocery, food delivery, seafood, pharmacy transport and daily chilled routes.

Cleaner than loose ice

A sealed pack helps avoid meltwater inside the bag or parcel.

Custom supply support

Tempk can support bag size, valve, label, branding and carton packing for bulk programs.

Handling instructions

Fill the 400ml water injection pack with clean water through the valve, then freeze it flat before use. Place the frozen pack inside the insulated parcel according to the tested layout.

Do not overfill or sharply fold the pack after freezing. Do not reuse a pack if the valve leaks, the film is punctured or the outer surface is contaminated.
