Chilled Packaging

One of the biggest challenges in selling chilled goods is keeping them at the right temperature during transport. Our range of insulated packaging is here to help, with an eco-responsible method of keeping your goods cold while in transit.

We offer paper based and recyclable chilled packaging that keeps your products cold. The range runs from insulated pouches and box liners to cool pak ice pads and specialist void fill. If you send food and drink, pharmaceuticals, or any field where things need to stay at the right temperature, you can trust RAJA UK to have the right packaging for you.

Our range covers

Our chilled packaging range covers insulation, coolant and the paper void fill that holds the cold air in place. Most chilled despatch needs one of each.

• Insulated pouches and envelopes – iFoodbag® for chilled food delivery packaging, and chilled pharma packaging such as an insulated pouch for medicine.
• Insulated box liners – RecyCold Climaliner and Climapack insulated paper packaging turn a standard carton into an insulated box. Both won gold at the Environmental Packaging Awards.
• Wool insulated pouches – this wool insulated packaging, uses natural wool as the insulation layer.
• Gel ice packs – Thermopac Gel Cool Pack, Hydropac Gel Cool Pack and the Ranpak® RecyCold™ gel ice pack, all flexible ice packs for food and pharma loads.
• Ice pads – CoolaPack Ice Pads and Hydropac Ice Cool Packs, long lasting ice packs that sit flat against the product.
• Insulated paper void fill – Ranpak® WrapPak® Protector Paper and its converter, a paper packaging for food alternative to plastic-based insulation.

Key features and benefits

Chilled packaging has to hold temperature, survive the network and still be something your customer can recycle. Ours does all three.

• Keep goods at temperature – insulated boxes and liners hold chilled and frozen loads through next-day and multi-day transit.
• Choose paper-based insulation – recyclable food packaging paper and wool avoid the polystyrene that much cold chain packaging still relies on.
• Match the temperature range – products cover +2/+8°C, 0°C to +10°C, and down to -45°C for insulated packaging for frozen food.
• Reuse the coolant – reusable ice packs and cool gel pack formats can be refrozen rather than thrown away, providing they are not damaged during last use.
• Fit your existing cartons – box liners turn a standard cardboard box into an insulation box, so you don’t need to hold two box ranges.
• Suit food and pharma – approved-for-food-use chilled food packaging solutions, plus iPharmabag® for pharmaceutical cold chain packaging.
• Fill the voids too – WrapPak® Protector Paper works as insulated void fill, holding the cold air where it’s needed.
• Buy at volume – pallet quantities of Climapack and packs of 200 ice pads keep high-throughput chilled despatch stocked.

Choosing the right chilled packaging

The right chilled packaging depends on the temperature you need to hold, for how long, and how the parcel gets recycled at the other end. When selecting packaging for chilled food or pharmaceuticals, consider:

• Temperature range – +2/+8°C suits most chilled food. Frozen and pharma loads need the wider -45°C to +30°C range.
• Coolant type – cool packs for food come as gel packs, ice pads and flexible formats. An ice pack for food should be approved for direct food contact.
• Insulation format – insulated pouches suit single orders. Box liners suit higher volume.
• Recyclability – paper and wool insulation goes into standard recycling. Check the product page for gel packs and liners, as materials vary.
• Presentation and food safety – confirm the product is approved for food use wherever it touches the product directly.

Examples include:

• iFoodbag® insulated paper pouches suit chilled food delivery in single-order volumes.
• Ranpak® RecyCold™ Climaliner™ suits turning existing cartons into insulated boxes for food delivery.
• Thermopac packaging suits chilled packaging gel packs, wool pouches and box liners from one supplier.
• iPharmabag® suits chilled pharmaceutical packaging and temperature-sensitive medical shipments.
• Climapack suits high-volume chilled product packaging bought by the pallet.

In short, insulate the box, add coolant matched to the transit time, and fill the voids so the cold air stays where it’s needed.

Chilled packaging handles temperature, not impact or humidity. Pair it with silica gel packets where condensation inside the carton is also a risk, and with the rest of our protective packaging range for shock and surface protection.

FAQs

What is chilled packaging?

Chilled packaging is insulated packaging plus a coolant, used to keep products within a set temperature range in transit. It covers insulated boxes, box liners, pouches and the ice packs that go inside them.

Is chilled packaging recyclable?

Our paper based and wool insulated products go into standard paper and textile recycling. Check the individual product page for gel packs and liners, as materials vary across the range.

What is the difference between gel packs and ice pads?

A cool pack gel format holds various forms of gel formula, whereas ice pads are filled with water.

Can ice packs be reused?

Yes. Our gel and water-based ice packs are reusable as long as they are not damaged, so refreeze them and they work again. Reusable ice packs cut the cost per parcel on closed-loop deliveries where packaging comes back.

What packaging do I need for chilled pharmaceutical shipments?

Chilled pharma packaging needs a validated temperature range, usually +2/+8°C, and insulation matched to the transit time. iPharmabag® insulated pouches are the starting point for most pharmaceutical cold chain packaging, with wool insulated pouches and liners being strong alternatives.

Where can I buy chilled packaging in the UK?

You can buy chilled packaging UK-wide from RAJA UK, with insulated pouches, box liners, gel packs and ice pads held in stock. Bulk and pallet quantities are available for high-volume chilled despatch, and there’s more on the topic in our guide to eco packaging for food.
