Corrugated Paperboard

What it handles

Corrugated paperboard is microwave safe, freezer safe, and handles moisture and grease effectively when treated with appropriate coatings. Its layered structure provides cushioning and rigidity for stacking and transport. It is not oven safe and should not be exposed to direct heat or open flame.

How it compares

Compared to plastic cake boards and food bases, corrugated paperboard offers compostability and recyclability with comparable structural support for most applications. Plastic alternatives may offer better moisture resistance in high-humidity environments, but corrugated paperboard eliminates plastic waste while meeting the needs of most bakery and catering operations. The tradeoff is slightly lower durability in prolonged wet conditions.

Choosing Corrugated Paperboard

Consider these factors when selecting corrugated paperboard products for your operation.

• Match size to product: Select cake pads and circles that extend at least one inch beyond your baked goods to provide adequate support and a professional presentation.
• Check grease resistance: Look for grease-resistant treatments when packaging items with high fat content or frosting to prevent oil saturation and maintain structural integrity.
• Consider display needs: Metallic and decorative finishes like scalloped gold circles enhance presentation for retail bakery cases and catered events without additional wrapping.
• Plan for waste streams: Corrugated paperboard can go into compost or recycling bins, simplifying back-of-house waste sorting compared to mixed-material alternatives.
• Stack with care: While corrugated provides good compression strength, avoid overloading stacks in walk-in coolers where condensation can gradually weaken the material.

Frequently asked questions

Is Corrugated Paperboard microwave safe?

Yes, corrugated paperboard is microwave safe. It can be used to reheat food items without risk of melting or releasing harmful substances.

Is Corrugated Paperboard compostable?

Yes, corrugated paperboard is compostable. It will break down in commercial composting facilities along with food waste, making it suitable for operations with composting programs.

Can Corrugated Paperboard go in the oven?

No, corrugated paperboard is not oven safe. It should not be used for baking or exposed to direct oven heat, as it can scorch, smoke, or ignite at high temperatures.

What is corrugated paperboard made from?

Corrugated paperboard is made from layers of paper pulp formed into a fluted inner layer sandwiched between flat liner sheets. The paper is typically made from wood fiber, often incorporating recycled content.

Is Corrugated Paperboard recyclable?

Yes, corrugated paperboard is recyclable. Clean, unsoiled pieces can go directly into paper recycling streams at most facilities.

Can Corrugated Paperboard be stored in the freezer?

Yes, corrugated paperboard is freezer safe. It maintains its structural integrity at freezing temperatures and is suitable for use with frozen cakes, desserts, and prepared foods.
