When it comes to choosing the right aluminum tray for your food packaging needs, the decision often comes down to two primary types: smoothwall and wrinkle-wall foil trays. As an
aluminium foil container supplier, Zhengzhou Eming understands the strengths and limitations of each—and more importantly, how they align with different business models and market requirements.
In this article, Eming will explore the key differences between smoothwall foil trays and wrinkle-wall from a manufacturer's perspective, focusing on strength, sealing, oven compatibility, visual presentation, production complexity, and cost implications. Whether you're a disposable food packaging distributor, dealer or importer , this guide will help you determine which tray is better suited for your product line and customer expectations.
1. What Are Smoothwall Foil Trays and Wrinkle-Wall?
1.1 Smoothwall Foil Trays
These trays feature a flat, polished surface with smooth walls and seamless corners. They're typically stronger, more premium-looking, and suitable for high-end or retail food packaging.
1.2 Wrinkle-Wall Foil Trays
These are the standard aluminum trays with ribbed or wrinkled sides, offering flexibility and affordability. They're widely used in takeout, food service, and catering.

2.1 Strength and Durability
Smoothwall foil trays are manufactured using a higher-grade aluminum alloy, and their structure is designed to maintain rigidity even when filled with liquid-based or oily foods. This makes them ideal for retail meal kits, frozen entrees, and premium catering where presentation and product protection matter.
Wrinkle-wall foil trays, by contrast, are more pliable. While they hold shape reasonably well, they are less resistant to crushing and may deform under pressure or high stacking loads. They’re best suited for short-term food delivery, takeout, or buffet use.
2.2 Sealing Options: Film Seal vs. Board Lid
One of the biggest differences lies in sealing technology.
- Smoothwall foil trays are designed for heat-sealing with lidding film (PET, PP, or foil laminate). This is essential for MAP (Modified Atmosphere Packaging) or vacuum-sealed frozen meals. The seal is leak-proof, tamper-evident, and retail-friendly.
- Wrinkle-wall foil trays usually cannot be film-sealed effectively due to their uneven surface. They’re often closed with a foil board lid, crimped or snapped on. While sufficient for transport, these lids may leak or loosen with heat, making them less reliable for long-term storage.
2.3 Oven and Microwave Compatibility
Both trays are made of oven-safe aluminum, but their performance differs in practical use.
- Smoothwall foil trays handle oven and freezer cycles better and maintain shape during reheating. This is crucial for meal prep brands or airline catering services where food is cooked or reheated directly in the tray.
- Wrinkle-wall foil trays are oven-safe too, but the creased walls may collapse slightly under high temperatures or heavy foods. They are not recommended for applications where visual appeal after heating matters.
2.4 Appearance and Shelf Appeal
For consumer-facing brands, presentation is everything.
Smoothwall foil trays offer:
- Sleek edges and smooth surfaces
- Option for colored lacquer coating (gold, black, red, etc.)
- Embossed branding on base
- Clear lidding film for product visibility
In contrast, wrinkle-wall foil trays are:
- More utilitarian
- Less attractive for retail shelves
- Usually silver only, with no surface treatment
If you are packaging premium meals, seafood, or upscale baked goods, smoothwall is the superior choice.
2.5 Manufacturer's Insight: Production Complexity and Cost
Tooling and Mold Requirements
- Smoothwall foil trays require precision molds and automated high-tonnage stamping machines.
- Tooling costs are higher, and setup for custom sizes or branded molds may cost thousands of dollars.
- Wrinkle-wall foil trays use simpler molds and can be mass-produced quickly with lower investment.
Material Usage
- Smoothwall foil trays require thicker gauge aluminum (typically 80–150 microns), increasing raw material cost.
- Wrinkle-wall foil trays can use thinner foil (50–90 microns), making them lighter and cheaper.
Minimum Order Quantities (MOQ)
- Smoothwall foil trays: MOQ is typically 100,000–200,000 pcs depending on customization.
- Wrinkle-wall foil trays: MOQ can be as low as 10,000–20,000 pcs, making them ideal for small businesses.
Lead Time
- Smoothwall foil trays may have longer lead times due to mold setup and coating processes.
- Wrinkle-wall foil trays can be produced and shipped more quickly.

4. Final Thoughts from Aluminium Foil Container Manufacturer
As a manufacturer of both smoothwall and wrinkle-wall aluminum foil trays, Zhengzhou Eming believes the best choice depends on your application, target market, and cost structure.
If your brand requires premium presentation, sealed freshness, or high structural integrity, smoothwall foil trays are the optimal solution. They offer a professional edge in competitive food retail environments.
If you're operating a cost-sensitive foodservice or takeout business, wrinkle-wall trays remain a reliable, budget-friendly option with fast production turnaround.
