shipping boxes

Shipping boxes are sturdy corrugated cartons made to protect goods while they are handled, stacked and carried to their destination. They suit parcels sent by courier, goods moved between warehouses, and online orders packed for customers. The best choice depends on the weight of the contents, how fragile they are, and how far the parcel will travel.

What shipping boxes are made to do

A shipping box has a harder job than a box that simply sits on a shelf. It may be lifted several times, placed on a conveyor, stacked under other parcels, and stored in a van or warehouse before it reaches the customer. Corrugated board helps it cope with that journey because the fluted layer between two flat liners gives cushioning and strength without adding a great deal of weight. That balance matters when a parcel is weighed and when a packer needs to move many boxes in a shift.

The shape of the box matters as well. A regular slotted carton with four flaps on the top and base is the most familiar style, and it packs and seals quickly. A mailer style box with a folding lid can give a tidier finish for customer facing parcels, while a long or tall box suits items that do not fit a standard cube. The right style keeps packing simple and keeps the contents still during transit.

Single wall and double wall board

Single wall board has one fluted layer and suits light to medium parcels, such as clothing, books, and small household goods. It is easy to handle, folds neatly, and stacks well when the packed weight is modest. Double wall board has two fluted layers and suits heavier goods, larger parcels, and boxes that will sit at the bottom of a stack. The extra layer adds crush resistance and helps the box keep its shape under load.

Choosing a wall grade for the load

Start with the packed weight and the fragility of the item, not with the size of the box alone. A light but fragile item may still need strong board and good internal protection, because a dented corner can damage the contents even if the parcel is not heavy. A heavy but robust item needs board that will not bow or split at the base. When in doubt, pack a sample, seal it as you would for dispatch, and check how it copes with stacking and handling.

Sizes that pack well and stack well

Measure the product as packed, including any wrapping or insert, then allow a small amount of room for protection and for easy packing. A box that is far too large lets the contents move, needs more filler, and can be awkward to stack. A box that is too tight can crush a label, bend a corner, or make the flaps bulge when taped. The aim is a snug fit that still closes flat.

Think about the outside size too, because couriers and storage systems work with the finished parcel. A tidy outside size stacks more safely, fits shelving better, and makes it easier to plan how many parcels fit in a vehicle or a storage area. Keeping a small range of well chosen sizes often works better than holding many sizes that are rarely used.

Sealing, labelling and stacking

Seal the base carefully first, because base failure is a common cause of damage. Use tape that suits the board and the weight, run it across the centre seam, and press it down firmly. Place the delivery label on a flat panel, clear of folds, tape, and edges, so it can be scanned easily. Stack boxes with the heaviest at the bottom, keep the tops flat, and avoid overfilling a box so the lid rises.

Shipping boxes for different kinds of parcels

Online orders often need a box that protects the product and presents it well on arrival. A clean exterior, a neat fold, and internal protection that holds the item in place all help the customer feel that the order was packed with care. For a house move or a storage job, strength and easy assembly matter more, and a plain strong carton may be the practical choice. For business to business shipments, consistent sizes help with palletising and with repeat ordering.

Fragile goods need extra thought. Glass, ceramics, electronics, and items with protruding parts benefit from dividers or shaped inserts that keep them away from the walls of the box. Paper void fill, corrugated pads, and corner protection can absorb knocks, but they work best when the item is held in the centre of the box rather than left to slide against a side panel.

Keeping parcels safe in wet and busy conditions

Corrugated board is strong, but it loses strength if it becomes soaked, so keep packed boxes dry and avoid leaving them outside in rain. If a parcel will pass through several hands, a secure seal and a clear handling note can help, but the note should never cover the delivery label. For very valuable or delicate goods, consider an inner box or extra padding, and check that the outer box still closes flat after the protection is added.

Recycling and reuse after delivery

Most corrugated shipping boxes can be flattened and recycled through household or business paper and card recycling, once tape and labels are removed where practical. Reuse is also sensible when a box is still clean and strong, for storage or for a return shipment. Avoid reusing a box that is torn, damp, or soft at the corners, because its strength will no longer be reliable.

Frequently asked questions about shipping boxes

What is the difference between single wall and double wall shipping boxes?

Single wall board has one fluted layer and suits light to medium parcels. Double wall board has two fluted layers and suits heavier parcels and boxes that will be stacked under other parcels.

How do I choose the right size of shipping box?

Measure the product as packed, including wrapping and any insert, then allow a small amount of room for protection. The box should close flat without bulging and without leaving a large empty space.

Can shipping boxes be recycled after use?

Yes, corrugated board is widely recyclable through paper and card recycling. Flatten the box and remove tape and labels where practical, and do not reuse a box that is torn, damp, or soft at the corners.

How should I seal a shipping box?

Seal the base first with tape suited to the weight, run tape across the centre seam, and press it down firmly. Keep the delivery label on a flat panel, clear of folds and tape.

How long do shipping boxes take after artwork approval?

Standard boxes usually take 10 to 14 working days after final artwork approval, and corrugated boxes usually take 12 to 15 working days. These are production lead times, not a guaranteed delivery date.
