Car Air Freshener Boxes.

Because fragrance migrates straight through uncoated board. Left in a plain carton, the product weakens on the shelf, the variants in a range start to smell of each other, and the nearby stock in a warehouse picks up the scent too. A foil or metallised liner on the inside face holds the volatile compounds in the pack.

It is not a standard feature of a folding carton, so it has to be specified.

Foil is the higher barrier and the one we suggest where shelf life is long or variants are stored together. Metallised board is the lighter, cheaper liner and does the job for faster-turning impulse lines. Both are laminated to a folding boxboard outer that keeps a bright surface for retail print.

Either way the freshener itself usually sits in a sealed inner sachet, so the liner is the second line of defence rather than the only one.

With a reinforced hang patch or a euro slot backed with extra material. Pegs are the dominant fixture for this product, at tills and forecourts, and the pack is thin and light, so the peg hole is the only structural point on it. A reinforced patch keeps the slot from tearing when the pack is pulled off the hook.

Multi-variant display packs are also available for a counter or a clip strip.

Full CMYK with gloss lamination, because the fixture is crowded and saturation wins the glance. Systematic colour coding across the range lets a shopper find the scent by colour before reading the name, and the fragrance name leads the panel. Foil detail adds metallic accents on premium ranges.

A window panel shows the freshener shape where that supports the sale, though the window is a gap in the liner and the sealed inner sachet does the work behind it.

Around 3.5 by 3 by 0.4 inches for a card format, with a sleeve version for the same product. Thin, light and low cost is the discipline, since this is an impulse purchase and the pack has to hit a price point. Dimensions are taken internally so the card and its sachet sit without slack.

Vent clips and hanging bottles need a deeper box, and we size to the item.

500 cartons per scent. A range of six fragrances is six designs, each at that quantity or more, and the barrier lining is priced into every one. Tiered pricing begins once a single design goes past 1,000 units.

Runs up to 100,000 per design are available for the big sellers.

Standard production is 7 to 10 business days from proof approval, with rush at 5 to 7 business days. A sample takes 5 to 7 business days, and we would put a live freshener in it for a week or two beside an unlined one to see the difference the liner makes.

Whatever you pay for the sample is credited to the production order.

Only if the retail packs are barrier lined; unlined variants stored together contaminate each other. The liner is what lets a mixed display pack or a shared shipping case work without the scents blurring into one. A sealed inner sachet on the product helps, but it is not something the carton can rely on alone.

For end of life, a foil-lined carton is mixed material and will not go in paper recycling the way plain boxboard does.
