In the fast food and beverage industry, packaging is part of the product. It carries not only the temperature and safety of food but also the brand’s visual identity. An oil-leaking or floppy package can instantly ruin customers’ good impression of your ingredients.With 10 years of expertise in food-grade packaging, Hanlong Crafts understands both structure and ingredients.
Check if your brand is facing these hidden cost risks before choosing a supplier:
| Pain Point | Consequence | Hanlong Solution |
| Failed oil & water resistance | Oil seeps through paper bags, staining hands and clothes, causing surging negative reviews | Upgraded coating technology: Single/double-sided coating with strong barrier to keep bags dry |
| Unbalanced heat retention & ventilation | Hamburgers get soggy, fried chicken skins turn soft, greatly reducing taste | Micro-vent structure: Hidden vents on box lids to expel excess moisture and keep crust crispy |
| Cumbersome & inefficient assembly | Slow packing during peak hours, long queues, high labor costs | One-piece structure: Patented folding design, tape-free, 3-second assembly, improving efficiency by 30% |
Hanlong Engineering Tip:Fast food packaging is not just “disposable supplies”. We prioritize paper stiffness and burst strength. For boxes holding crayfish or sauced fried chicken, high-gram kraft paper (≥350gsm) with reinforcement is required to avoid softening or handle breakage.
We reject “one-size-fits-all” solutions. Supported by mold advantages in our 10,000 ㎡ production base, we provide full-scenario custom solutions including tray, handle, top-bottom and special-shaped structures.
| Box Type | Structural Features | Best For | Hanlong Craft Advantages |
| Tray Style | One-piece, open design, adjustable depth | Hamburgers, sandwiches, sushi, snacks | Leak-proof bottom with reinforcement, no seepage even for sauced pasta |
| Handle Box | Built-in handle, self-locking, tape-free | Fried chicken buckets, family buckets, cakes, fruit gifts | Reinforced handle with double-layer thick cardboard, tear-resistant up to 5kg load |
| Top & Bottom Cover | Deeper lid, fully wrapped, dustproof, ceremonial | Premium sets, high-end bento, mooncake/pastry boxes | Millimeter-level die-cutting precision for smooth, well-fitted opening and closing |
| Clamshell Box | Integrated flip-top, auto-locking, fastest service | Chinese fast food, salads, rice noodles | 3-second assembly with pre-scoring, one-hand operation |
| Custom Special Shape | Customized to brand IP or product shape (car, animal, etc.) | Kids’ meals, limited editions, marketing campaigns | Exclusive mold development based on your logo or mascot |
Hanlong Engineer Tip:
Stress distribution at the handle is critical. We use mechanical simulation to ensure no tearing under heavy loads. Add heat vents for hot food and condensation guides for cold food.
Safety is the top priority for food-contact packaging. Hanlong ensures all materials are safe and eco-friendly.
| Material System | Core Advantages | Eco Feature | Typical Use |
| Food-grade white cardboard | Vivid printing, smooth surface, great for IP patterns | Recyclable & biodegradable | Hamburger boxes, tart boxes, dessert trays |
| Natural kraft paper | High temperature resistance, oil-proof, artisanal vibe | 100% natural biodegradable | Fried chicken buckets, snack bags, pizza boxes |
| PLA coated paper | Replaces traditional PE coating, fully biodegradable, heat-resistant | Industrial compostable | Liners requiring oil/water resistance |
