Fast Food Packaging Case ——Upgrading Takeout Experience for a North American Fried Chicken Chain
Client: North American fried chicken chain (takeout + delivery)
Core Needs: Oil resistance & leakage prevention, structural compression resistance, faster order assembly efficiency
1. Project Background
We partnered with a fast‑expanding fried chicken brand in North America. As delivery orders boomed, the brand suffered from common packaging pain points:
- Oil seepage through conventional paper boxes
- Stained bags and customers’ hands
- Flimsy boxes crushed on motorcycle delivery
- Damaged “crispy” reputation

2. Hanlong’s Solution
We did not simply change paper materials. We redesigned the entire packaging from structural mechanics and dining experience.
Grease Barrier Technology
Replaced standard paper with single / double‑side PLA coated paper.
We tested grease penetration on different chicken cuts to ensure no seepage even on the oiliest parts.
Structural Reinforcement
Added cross reinforcement at the bottom and upgraded to dual‑lock lid tabs to prevent collapsing when lifting full boxes.
Balanced Breathability & Heat Retention
Designed invisible micro‑vent system on the lid:
- Releases excess moisture to keep skin crispy
- Retains heat for ideal serving temperature
Speed Efficiency
Simplified folding with pre‑scored 3‑second assembly structure.
No tape needed; staff seals with one hand, cutting peak‑hour wait times.

3. Results Delivered
- Zero complaints: No more negative reviews about oil stains on clothes.
- Brand upgrade: Matte black + gold foil logo elevated perceived value.
- Full compliance: All materials passed FDA food‑contact certification for retail and delivery platforms.

Hanlong Engineer Tip
Many fried chicken shops use cheap recycled paper, which weakens and breaks in hot oil.
Hanlong uses virgin wood pulp paper for superior strength and durability. The box stays intact until the last bite.
