Start With the Box, Not the Label

Most packaging problems begin before a single label is printed. If the box is too big, too flimsy or too thin for what is going inside, no amount of careful taping will save you. Your parcel will be stacked, tipped onto a conveyor and quite possibly dropped before it reaches the doorstep.

Start with three questions: how heavy is the item, how fragile is it, and how far must it travel? A jar of preserves crossing the county is a different job from six ceramic mugs heading to the Highlands. Answer those honestly and the box, the void fill and the label all fall into place.

One practical rule: leave around 5 centimetres of clearance on every dimension. It sounds generous, but it gives you room for cushioning on all six faces, which is what actually protects the contents.

Choose a Board Grade That Matches the Journey

Corrugated board is graded by strength, and for everyday small business use the simplest distinction is single wall versus double wall.

• Single wall suits light, robust items such as clothing, books and unbreakable accessories. It is cheaper and lighter, which keeps postage down.
• Double wall is worth the extra pennies for anything heavy, valuable, stackable or fragile. It resists crushing when parcels are piled up in a van.
• Rigid mailers and book wraps work well for flat items, where bending is the main risk rather than impact.

Match the box to the contents rather than the other way round. A wide, shallow box with lots of empty space needs more void fill, and void fill is weight you pay to post. Where you can, keep a small range of sizes — perhaps three or four — instead of one box expected to cope with everything. If you are having boxes printed, confirm the board grade with your supplier before approving the artwork; it is far easier to change a specification than a print run.

Void Fill Is What Stops Things Moving

Items rarely break simply because they were dropped. They break because they moved inside the box and met a hard surface at speed. Void fill has one job: to hold the item still and absorb energy.

• Fill the corners first. Corners take the worst of any impact, so build a cushion there before you place the item in.
• Match the material to the weight. Paper void fill is fine for light goods, but heavier items need something with more resistance, such as dense paper pads or moulded pulp.
• Mix and match. A layer of tissue or bubble wrap directly around the product, plus loose fill around that, gives you both surface protection and shock absorption.
• Fill to the top. When you close the lid there should be gentle resistance. If the flaps fall shut with no pressure at all, movement is waiting to happen.

Wrap small items separately rather than tipping several loose ones into the same space. Two mugs rattling against each other will chip; two mugs each wrapped and separated will not.

Where You Place the Label Matters

A label that peels, smudges or gets read by the wrong scanner costs you a replacement parcel and an unhappy customer. Placement is as important as print quality.

• Use the largest flat face. Avoid corners, seams and the edges where the box flexes.
• Keep tape off the label where you can. It can wrinkle, reflect light and confuse a scanner.
• Leave a margin. Aim for 2 to 3 centimetres of clear board around the label so sorting machinery has something to grip.
• Print barcodes on a matte surface. Glossy labels look smart but create glare that can stop a handheld scanner reading first time.
• Protect the print. A clear overlay or waterproof label stock keeps addresses readable in the rain.

If you include a returns label inside, make it easy to find and mention it on the outside — it saves your customer hunting through the packaging later.

Seal and Weatherproof Properly

Tape is not just a closure; it is part of the structure. A single strip down the centre of a box does very little. Run tape along the centre seam and then across both end seams so the flaps are locked together. A good quality paper or vinyl tape with a strong adhesive will hold far better than a thin, cheap roll, especially in cold weather.

For anything that cannot get wet, add an inner polythene bag or waterproof liner. Cardboard softens quickly when damp, and a soggy box loses much of its strength long before it collapses visibly. If your products are food, cosmetics or anything damaged by moisture, this step is not optional.

Test Your Packs Before You Post Them

You do not need a laboratory to check whether your packaging works. Pack a sample exactly as you would for a customer, then drop it from waist height onto a hard floor — once on a corner, once on an edge, once flat. Then shake it. If you can hear or feel movement inside, add more void fill.

Stack a few packed boxes on top of one another and leave them for a day to see how the bottom one copes. If the board bows or corners crush, move up a board grade. It is far cheaper to test three parcels at your kitchen table than to replace three orders and lose a customer.

Review your packaging every few months as your range grows. A setup that worked beautifully for jewellery may not survive a shipment of candles, and a small adjustment to box size, fill or label placement is often all it takes to keep your parcels arriving in the condition you intended.
