Medium Corrugated Burger Boxes

1. Product Overview

The Lumapack Medium Corrugated Burger Box is a sturdy, food-grade packaging solution designed for standard burger portions in professional foodservice environments. Built from double-wall corrugated paperboard in a natural kraft finish, this box provides reliable structural support and passive heat retention during packing, service, and delivery.

Measuring 140mm (length) × 110mm (width) × 45mm (height), the medium format is well suited for regular-sized beef, chicken, or plant-based burgers served across takeaways, restaurants, food trucks, and catering operations. The corrugated construction adds rigidity compared to standard single-layer burger boxes, helping the box maintain its shape when filled with hot food and handled through typical service workflows.

Manufactured from responsibly sourced kraft paperboard, the box is food contact safe and BPA-free. No PFAS added. The corrugated structure provides a functional barrier against heat transfer, helping to keep contents warmer for longer without softening the outer surface during handling.

2. Typical Foodservice Uses

The Medium Corrugated Burger Box is selected by foodservice operators who need a reliable, heat-retaining container for standard burger portions across a range of service formats.

Common applications include:

• Standard beef and chicken burgers served at counter-service restaurants and quick-service operations where portion size is consistent and presentation matters
• Plant-based and specialist burgers offered by independent restaurants, food trucks, and delivery-first kitchens where a clean kraft aesthetic supports the brand identity
• Takeaway and delivery orders where the corrugated structure helps maintain box integrity and heat retention from kitchen to customer
• Event and festival catering where robust single-use packaging is required for high-volume service in outdoor or temporary environments
• Dine-in table service where a self-contained burger box simplifies plating, supports portion control, and reduces washing up for casual dining formats

The medium format is particularly suited to operators running consistent, standardised menus where portion size does not vary significantly across shifts or locations. The kraft finish is widely used across independent burger restaurants and delivery-led concepts where a natural, unfussy appearance complements the food presentation.

3. Operational Benefits

• Corrugated structure supports heat retention during service: The double-wall corrugated construction creates an air gap between the food and the outer surface of the box. This provides passive insulation that slows heat loss during packing and short-distance delivery, helping food arrive at a better temperature without any additional wrapping or insulation.
• Maintains structural integrity with hot food contents: Unlike single-layer paperboard boxes that can soften when filled with hot, sauced burgers, the corrugated build maintains rigidity through typical service handling. This makes the box easier to carry, stack briefly during service, and hand to customers without losing its shape.
• Suitable for hot food service conditions: The kraft paperboard and food-grade construction means the box performs reliably with standard hot burger applications, including those with sauces and hot toppings, under normal foodservice conditions.
• Consistent sizing supports efficient packing workflows: The fixed dimensions (140mm × 110mm × 45mm) provide a reliable reference for kitchen packing stations. Staff can pack burgers quickly and consistently without adjusting for different box sizes, supporting speed of service during busy periods.
• Stackable for storage and transport: The box design allows cases to be stored efficiently in back-of-house environments, and individual boxes to be stacked during preparation, helping manage space in compact kitchen settings.
• Clean kraft finish for professional presentation: The natural kraft finish provides a neutral, widely used aesthetic that works across casual dining, street food, delivery, and catering contexts without requiring additional branded wrapping for everyday service.

5. Why Choose Lumapack Medium Corrugated Burger Boxes

Corrugated burger boxes represent a step up from standard flat-sheet paperboard formats commonly used in budget takeaway operations. The structural difference is functional, not just aesthetic: the corrugated construction adds rigidity and passive insulation that a single-layer box cannot provide, making it a practical choice for operators where food quality during delivery or counter service matters.

Corrugated construction vs. standard paperboard

Single-layer kraft burger boxes are lightweight and cost-effective for low-stakes service, but they can soften quickly when filled with hot, sauced food — particularly in delivery scenarios where the box is sealed and held for several minutes. The corrugated format provides better resistance to heat-induced softening, helping the box hold its form from kitchen to customer.

Medium format for standard portions

The 140mm × 110mm × 45mm dimensions are calibrated for regular burger portions — the size most commonly served across casual dining, quick service, and delivery menus. This is neither a compact snack-size box nor an oversized format that creates unnecessary bulk around a standard burger. Operators looking for flexibility across portion sizes can pair this medium format with Lumapack's Small Corrugated Burger Boxes and Large Corrugated Burger Boxes from the same range.

Kraft finish for versatile branding contexts

The natural kraft appearance is one of the most widely used finishes in the burger and street food sector. It works equally well in independent burger restaurants, market stalls, cloud kitchens, and catering environments without appearing out of place. For operators requiring a different aesthetic, Lumapack's Medium Kraft Burger Boxes offer a comparable format in the same size group.

Consistent quality across cases

Lumapack's quality control process ensures that box dimensions, corrugation integrity, and material specification remain consistent across cases. This supports predictable packing workflows and reduces the variation that can occur with lower-specification suppliers.
