Eco‑Friendly Kraft Box for Takeout Catering

Material characteristics 1.The design of this perforated kraft paper box is far more than simply punching a few ventilation holes into a paper lid — it is a systematic engineering effort spanning structural mechanics, material formulation and food safety. 2.Structurally, the ventilation holes on the lid are precisely calibrated for diameter and spacing. The aperture is controlled within an optimal range, holes are evenly distributed, and their quantity is set according to the heat-dissipation curve of common fried and grilled foods — ensuring excess moisture escapes continuously without causing rapid heat loss from over-perforation. The lid features a slightly domed profile that creates a gap between the lid and the food surface, preventing crispy coatings from directly contacting the inner lid and becoming soggy from condensed moisture — a structural detail that plays a critical role in preserving texture. All four corners of the box body employ a locked-edge creasing craft that rein…
