成形パルプ製のヴィンテージ風卵パック

With repeated opening over weeks, eventually yes. The deep single fold concentrates flex in one line, which is the trade for a lid that lays flat. Modern multi-crease hinges last longer through reuse cycles. If your customers routinely return cartons for refilling, the modern profile is the more practical specification.

The twelve cell runs slightly shallower than a modern domed carton at around 68 mm tall against 75 mm, so it fits comfortably where a modern one does. Length is the same. Buyers switching between profiles do not usually need to change anything downstream.

Yes, and the flat panel is the reason. Multi-color flexographic work holds registration on a flat surface in a way it cannot on a dome. Bear in mind that pulp texture softens fine detail regardless of print quality, so illustrations with heavy line work reproduce better than photographic images.

Better, in fact. A flat surface bears directly on the base of the carton above with no contour to slide against, so stacks stay square. What the flat top loses is the arch strength a dome provides, which we compensate for with rib structure underneath the panel. Net top load performance is comparable.

They are newly manufactured to a historic profile. Genuinely old cartons are not food safe, since fiber packaging absorbs whatever it has been stored with and has no traceable material history. Our vintage cartons are produced from the same recycled pulp as the rest of the range, on molds cut to reproduce the flat top geometry
