Packing chilled product for delivery is one of those tasks that seems simple until you look at the failure rate. Most perishable freight that arrives out of condition was not let down by the vehicle. It was packed in a way that could not survive the journey it was given.

This is a working checklist for teams packing same-day perishable orders.

Before you pack. Confirm the product is at target temperature, not approaching it. Confirm the carton and any insulated liners have been stored somewhere cool rather than in a warm dispatch area. Confirm you know the delivery window, because a two-hour metro run and a next-morning regional delivery need different packing.

Choose the right container. Insulated liners or polystyrene for anything with a journey longer than an hour. Right-size the box: a large carton with a small amount of product has a lot of air to keep cold and a lot of room for items to move. Void fill matters for temperature as much as for breakage.

Condition your coolant. Gel packs straight from a deep freeze can push adjacent product below zero and cause freeze damage, which for many chilled foods is as much a rejection as being too warm. Let them come to a slush state. Place them above the product where practical, since cold air falls.

Separate what needs separating. Raw and ready-to-eat should not share a compartment. Strong-smelling product will transfer. Anything that leaks needs its own sealed bag regardless of how confident you are in the packaging.

Seal and label. Tape all seams to slow air exchange. Label the outside with "Keep Chilled" or "Perishable", the product name, and the pack date. If your customer needs to know a use-by, it should be readable without opening the carton.

Time the handover. Pack as close to pickup as you reasonably can. If a courier is due at two, packing at eleven adds three hours of unnecessary risk. Where the timing cannot be tight, hold the packed carton in the chiller rather than on the bench.

Brief the driver. Anything unusual, a fragile item, a specific unloading instruction, a customer who is only on site until three, should be on the job rather than in your head.

Match the service to the goods. None of the above compensates for the wrong freight product. Perishables need a temperature-controlled chilled delivery service with a same-day window, not a general network with an overnight depot stop.

Afterwards, check. Ask two or three customers each month to confirm the condition on arrival. It takes five minutes and it is the only way to know whether your process works in the real world rather than on paper.

Write it down and train to it. A packing standard that lives in one experienced person's head fails the week they take leave. A single-page procedure with photographs of a correctly packed carton, kept at the bench, is one of the highest-return documents a small food business can produce. Review it after each summer, when you have fresh evidence of what did and did not hold up.

Most perishable failures trace back to two things: product packed warm, and product waiting too long between chiller and vehicle. Fix those and the rest is refinement.
