How to Ship Frozen Food? Useful Methods and Tips

In the world of perishable goods deliveries, shipping frozen food remains one of the most delicate logistics operations. That is why, at INATECH Packaging, we have specialised in providing complete packaging and thermal protection solutions, enabling our partners to deliver safely, without losses or compromises.

If you are a company delivering frozen food products, whether in e-commerce, artisanal production, hospitality or distribution, we understand how important it is to keep the cold chain intact until delivery. Below, we provide a complete guide with essential methods and recommendations.

What should you know before shipping frozen products?

Every parcel containing frozen products has its own particularities. Based on our experience, production or distribution companies that ship correctly ask themselves a few simple questions:

• At what temperature must the product remain throughout the delivery?

• How long does transport take? (24h? 48h? Over the weekend?)

• Will you use a standard courier or dedicated refrigerated transport?

• How many units are being shipped and what is their volume?

The answers to these questions determine the right packaging and cooling system. At INATECH Packaging, we provide personalised advice based on the product, delivery duration and season, helping you find the best combination of insulated packaging + refrigerant.

The right packaging makes all the difference

For frozen products, thermal insulation is essential. We recommend several tested and effective solutions, available directly from inatech-shop.ro:

• thermal boxes (EPS): ideal for national transport, they maintain a constant temperature for up to 48h when used with cooling gels;

• Cardboard boxes + bubble or aluminium thermal foil: a more sustainable, lightweight and effective alternative;

• Insulated envelopes;

• Container liners;
• Insulated boxes for shipments under controlled-temperature conditions;

• Reusable composite-material packaging: recommended for B2B partners with closed logistics cycles.

Refrigerants: which one should you choose and when?

Insulating the parcel is not enough; you also need a cold source to maintain a constant temperature.

Here are the main options available on inatech-shop.ro:

• Reusable refrigerant gels: the easiest to use, they can be frozen at -18°C and maintain cold temperatures for 24–48h;

• Dry ice (solid CO2): for rapid transport and very low temperatures; it requires special packaging and appropriate marking;

• Eutectic plates: for predictable routes and standardised containers.

We can help you calculate exactly how many gels or plates you need for a specific type of parcel, based on the initial temperature and transport duration.

Transport: standard or specialised?

If you deliver locally or to an area well served by refrigerated fleets, you can opt for refrigerated transport. However, many companies ship via standard courier, which means responsibility for maintaining the temperature rests entirely with the packaging.

In these cases, it is essential to test the packaging system in advance. At INATECH Packaging, we provide samples and free technical advice, allowing you to simulate real transport conditions and see whether the product remains protected until delivery.

Do not forget labelling and instructions

Professional shipping also includes providing the recipient with the correct information. We recommend including:

• a clearly visible label: “Frozen product, store immediately in the freezer”;

• A label with special handling instructions (“Do not expose to heat”);

• Optional: a temperature sensor (for real-time tracking).

In addition, we suggest informing customers in advance that they will receive a perishable product and that they need to be present at delivery.
