1. What is Coated Kraft Refrigerated or Frozen Packaging?

Coated kraft packaging refers to kraft paperboard that has been treated with a food-safe coating to improve moisture resistance, durability, and printability. This coating allows the kraft material to withstand cold, wet, and freezing conditions, making it suitable for refrigerated or frozen products.

Unlike standard kraft paper, coated kraft combines the strength of natural fibers with the protective benefits of a thin coating. It is ideal for a wide range of products, including:

• Dairy products such as milk, yogurt, and cheese

• Frozen meals and ready-to-eat dishes

• Beverages requiring chilled storage

• Frozen desserts such as ice cream and sorbets

• Frozen seafood, meats, and prepared foods

2. Benefits of Coated Kraft for Refrigerated or Frozen Products

2.1 Durability and Strength

Kraft paperboard is naturally strong and rigid. The coated surface adds a layer of protection, making boxes resistant to moisture, condensation, and tearing—common challenges in refrigerated and frozen environments.

2.2 Food Safety Compliance

Coatings applied to kraft packaging are food-safe and FDA-approved, ensuring they are suitable for direct or indirect contact with consumables.

2.3 Eco-Friendly and Sustainable

Coated kraft paperboard is usually recyclable and made from renewable resources. Brands can demonstrate commitment to sustainability without compromising the functional needs of cold storage or frozen products.

2.4 Excellent Printability

The coating allows for high-quality printing, making it possible to display logos, nutritional information, promotional graphics, and vibrant designs, even on packaging exposed to moisture.

2.5 Versatility

Coated kraft refrigerated or frozen packaging can be manufactured in multiple styles, including:

• Folding cartons

• Tray-style boxes

• Carry-and-display boxes

• Sleeve-style packaging

• Multi-pack cartons

This versatility makes it suitable for retail, delivery, and promotional purposes.

3. Key Design Considerations

When designing coated kraft refrigerated or frozen packaging, brands should consider the following:

3.1 Moisture Resistance

Freezing and refrigeration can create condensation. The coating ensures the box retains its shape and integrity, preventing soggy surfaces or weakened structures.

3.2 Temperature Tolerance

Packaging must withstand low temperatures without cracking, curling, or delaminating. Selecting the right coating and board thickness is critical.

3.3 Product Protection

For fragile items like frozen desserts or glass bottled beverages, the internal structure is key. Inserts, partitions, or dividers can keep products stable during transportation and storage.

3.4 Sustainability Goals

Eco-conscious brands often require recyclable or compostable coatings. Selecting water-based or biodegradable coatings enhances sustainability credentials.

3.5 Branding and Print Design

The coated surface supports sharp, high-quality printing for logos, product information, and marketing designs. This is especially important for refrigerated or frozen foods where clear labeling is essential for consumers.

4. Materials and Coating Types

4.1 Paperboard Core

Most coated kraft refrigerated or frozen boxes are made from high-strength kraft paperboard (often 250–400 gsm) to handle cold and wet conditions.

4.2 Coatings

• Polyethylene (PE) Coating: Provides excellent moisture resistance, ideal for refrigerated and frozen storage.

• Water-Based Coating: Eco-friendly alternative to PE; provides moderate moisture resistance and recyclability.

• Wax Coating: Traditional method for frozen foods; less common today due to recycling challenges.

The choice of coating affects durability, recyclability, and print quality.

5. Applications in Food & Beverage Industry

5.1 Dairy Products

Milk cartons, yogurt boxes, and cheese packaging benefit from coated kraft packaging due to moisture and cold resistance. Custom printing enhances brand visibility.

5.2 Frozen Foods

Ready-to-eat meals, frozen vegetables, and seafood are often packed in coated kraft boxes to prevent damage during freezing, transport, and retail display.

5.3 Frozen Beverages and Desserts

Ice cream, frozen juices, and beverage concentrates require packaging that can handle low temperatures without warping or losing integrity.

5.4 Multi-Pack Retail Displays

Coated kraft carry-and-display boxes allow chilled or frozen products to be displayed on shelves while ensuring safe handling and high visibility for consumers.

7. Sustainability Considerations

Brands increasingly prefer coated kraft because it:

• Uses renewable resources (wood pulp from sustainable forests)

• Is recyclable or compostable depending on coating choice

• Reduces reliance on plastic packaging

• Supports corporate sustainability targets

Choosing water-based coatings or recyclable PE coatings ensures that the packaging aligns with environmental goals.
