The four grades that cover almost everything
Lip balm cartons are made from one of four board families, and the choice between them is usually settled by two questions: does the print need to be bright, and does the pack need a recycled or unbleached story.
SBS folding boxboard is bleached, coated on the print side and bright white underneath the ink. It is the default for full-colour cosmetic cartons because colours reproduce close to their intended values. Kraft board is unbleached, uncoated and brown, so it prints warm and dark and cannot produce a true white without an opaque underprint. Recycled greyback board has a white printing face over a grey reverse. Rigid greyboard with a printed wrap is a different construction entirely and belongs to gift packaging.
How each grade behaves under ink
This is where most surprises happen. The same artwork file produces genuinely different results on these four surfaces.
| Board | Colour accuracy | Fine detail | True white |
|---|---|---|---|
| SBS coated | Close to proof | Holds small type and fine halftones | Yes, unprinted board |
| Kraft uncoated | Warmer and darker throughout | Softens below about 7 pt | Only with an opaque white underprint |
| Recycled greyback | Good on the coated face | Slightly softer than SBS | Near white, marginally duller |
| Printed wrap on greyboard | Same as the wrap stock used | Very good on smooth art paper | Yes on a coated wrap |
Board weight matters more than grade for strength
Brands often ask which grade is strongest. In practice, weight dominates. An 18pt SBS carton and an 18pt kraft carton behave similarly under load; a 14pt carton in either grade will feel flimsy on a shelf.
For one 0.15 oz stick, 14pt to 18pt is enough. For a carton over three inches tall, or one holding more than one tube, move to 20pt or 24pt. For a counter display unit holding a dozen sticks, E-flute corrugated rather than any paperboard.
The exception is a hanging pack, where load concentrates at a single die-cut slot and reinforcement matters as much as thickness. That is covered in more detail on our page for balm cartons with a peg hook tab.
What each grade costs you
Material is a smaller share of a folding carton's cost than most people assume, particularly at low volumes where setup and tooling dominate. At high volumes it becomes significant.
Broadly: recycled greyback is the least expensive per sheet, SBS sits in the middle, kraft is comparable to SBS or slightly above depending on the grade, and rigid construction is in a different bracket altogether because of the greyboard, the wrap and the hand assembly.
The more useful cost question is which grade lets you avoid a production pass. A design that works on kraft with two spot colours and a varnish is cheaper than the same design on SBS with four-colour process and a laminate, and the difference is larger than the board itself.
Disposal, and being accurate about it
All four paperboard grades are compatible with standard US kerbside paper recycling in their plain or varnished state. What complicates that is what goes on top: a plastic laminate film, a metallised layer or a film window patch all mean the consumer has to separate materials, and metallised board is not paper-recyclable at all.
If end-of-life is central to your positioning, the specification that keeps things simplest is an uncoated or varnish-only board with a printed swatch instead of a window. That is a genuine constraint on how the pack can look, and it is worth deciding deliberately rather than finding it out after artwork.
Recycled content is a separate question from recyclability, and the two get conflated frequently. Ask a supplier what percentage of post-consumer content a specific stock carries rather than accepting a general claim, and only state on pack what you can substantiate.
Choosing quickly
If the range depends on shoppers distinguishing bright colours at arm's length, use coated SBS. If the product is positioned as natural, unbleached or low-waste, use kraft and accept muted colour. If you need a cost floor at volume and a white reverse does not matter, use recycled greyback. If the pack is a gift and the opening moment is part of what you are selling, look at rigid construction and expect a different price bracket.
Whatever you choose, ask for a printed proof on the actual stock. Board is the one variable that a screen proof cannot represent.
