Paper packaging is a construction decision before it is a claim. The board, the insert, the closure and the print decide both the protection and the wording that can be printed, and each is a specification line rather than a preference.
This guide is part of our Charger Packaging & Sustainability. Read the full topic guide for the decisions that come before and after this step.
Paper packaging for chargers: the four decisions
The board and weight, the print method, the insert and the closure.
The four are taken in that order because each constrains the next: the board weight sets the protection available, the print method follows the board, the insert carries the product and the closure keeps the pack shut.
The cost of paper packaging is mostly fixed charges and freight, which is why a light carton that loads a full pallet usually beats a heavier one that looks better.
Decision 1: the board and the weight
The weight decides the protection and the freight.
A heavier board survives more handling and costs more to move; a lighter board reduces the freight and needs a better insert to carry the product. The two are chosen together rather than consecutively, because the insert compensates for what the board gives up.
Decision 2: the print method
One colour, several colours or process print.
A single-colour print on uncoated board is the cheapest fixed charge and the simplest to describe; a process print needs a coated surface for accurate colour and adds a plate set. The choice follows the channel: a shelf pack earns the print, a channel shipment often does not.
Decision 3: the insert
The part that carries the product.
A folded board insert is the cheapest and the easiest to describe; a moulded pulp insert holds a shaped product better and costs more; a plastic tray is the most protective and adds a second material. The insert is where the drop performance is decided.
Decision 4: the closure
Glue, tuck or tape.
A tuck flap avoids adhesive and is common on a retail carton; glue gives a stronger box and cannot be reopened; tape belongs to the shipper rather than the unit. The closure is part of the assembly and therefore part of the specification.
| Decision | Options | Effect on cost | Effect on protection |
|---|---|---|---|
| Board and weight | Light to heavy, virgin or recycled | Material and freight | The baseline |
| Print method | One colour, several, process | Fixed charge per version | None |
| Insert | Folded board, pulp, plastic | Material and tooling | The largest single factor |
| Closure | Tuck, glue, tape | Small | Handling and returns |
What the specification should record
Five lines, and each is checkable.
The board type and weight; the print method and colour count; the insert material and construction; the closure; and the carton dimensions with the pallet pattern. Those five lines are what a reorder is placed against.
Where paper packaging goes wrong
Three patterns, and the third is the most expensive.
A lighter board without a stronger insert; a process print on an uncoated surface, which gives an inaccurate colour; and a carton approved as a flat proof without being assembled. Each is settled before the plates are made.
Claims the specification supports
Three sentences, and each names a material.
Uncoated fibre board with a single-colour print; no window and no laminate; a folded board insert from the same material. Each describes the pack rather than an outcome, which is what makes the wording defensible.
How the paper choice affects freight
The board weight and the carton volume decide how many units travel per container, and a slightly deeper carton can cost a pallet layer. That is why the carton data is part of the packaging decision rather than a detail for the forwarder.
Where the pack is verified
The drop and transport test on the assembled pack is what confirms the insert and the board together. A flat proof and a board specification describe the materials; only the test describes the protection.
Where the paper pack is verified
The assembled pack is drop and compression tested, because the board and the insert behave together. The result is recorded with the packing specification, and it is the check a lighter carton has to pass before it replaces a heavier one.
How the pack is compared across two quotations
Two paper packs are compared on the lines that decide the freight and the protection rather than on the unit price alone. The board type and weight, the print method, the insert construction and the carton dimensions with the pallet pattern are the four that move the numbers.
The fifth line is the proof. A quotation that includes a proof on the production board is not comparable with one that assumes a white sample, because the colour and the surface are the subject of the approval rather than a detail.
The comparison also covers what the pack claims. A specification naming the ink and the adhesive supports a description of the pack, while a claim about processing depends on systems outside the quotation.
A buyer comparing on those lines reaches a decision on the landed cost and the protection together rather than on the carton price.
FAQ
Is paper always the lighter option?
Not necessarily. A heavier fibre board with a strong insert can weigh more than a thin carton with a moulded tray, and the freight follows the weight and the carton volume. Compare the weight and the carton volume together, because a heavier board with a stronger insert can load fewer units per pallet and the freight follows both numbers. Compare the two options on the units per pallet.
Can a process print be used on recycled board?
It can, although the surface absorbs more ink and the colour shifts. The proof is made on the actual board rather than on a white sample. Prove the print on the board that will be used for the run, because a recycled surface absorbs differently and the approved colour has to be judged on it. Ask for the proof on the production board before the run is scheduled.
Does the insert have to be the same material?
It does not have to be, and a single-material pack is easier to describe and to process. The choice is made with the drop performance rather than separately. Choose the insert with the drop performance rather than separately, because the insert is what carries the product through transit. A moulded insert costs more in tooling and weight, so it is chosen with the drop result rather than before it.
What carton data is needed?
Dimensions, gross weight, units per carton and the pallet pattern; those four decide the freight and the warehouse handling. Add the carton count per pallet to those four, because it is what converts the pack specification into the freight and the warehouse handling. Those four are what the freight calculation and the warehouse need, and they are the lines a reorder is placed against.
