成形パルプ製のピンク色の卵パック

Sample production runs to a physical formed sample, which is what you should approve rather than a flat chip. Building the shade, forming samples, and shipping them for approval takes time before production can begin. We recommend starting the approval cycle well ahead of a seasonal deadline, since October and Easter campaigns fail on timing far more often than on color.

Brown and blue-green shells give the strongest result, since both contrast against pink. White eggs in a blush carton can look washed out because the tonal values sit close together. Producers running white eggs usually specify mid pink or deeper for that reason.

Yes, on the same basis as our natural cartons. The pigment is selected for compostable packaging use and is present in very small quantity by mass, with no coating or film involved. As with any compostability claim, the wording should match the certification actually held and the disposal infrastructure in your market.

Slightly, and the reason is rejection rate rather than pigment cost. Because pink is a light tint over a variable gray base, more batches fall outside the shade tolerance and get diverted. Darker colors absorb base variation and run cleaner. The difference is modest but it is real, and any supplier quoting all colors identically is probably not shade checking.

With a retained physical standard on file, variation is small enough that cartons from different runs look the same on a shelf side by side. Without one, expect noticeable drift, since incoming recycled fiber varies seasonally and pink shows that variation more than any other shade. Approving and retaining a standard at first production is the single most useful thing a pink buyer can do.
