• E-commerce Readiness: Packaging must be robust enough to withstand the rigors of shipping and delivery.

What Materials Work Best for Food Packaging?

The choice of packaging material depends on several factors, including the product's characteristics (wet/dry, acidic), storage conditions, desired shelf life, and branding requirements. Here are the most common and emerging options:

1. Plastics: Versatility Meets Sustainability Challenges

Plastics remain a dominant force in food packaging due to their low cost, versatility, and excellent barrier properties.

• Common Types:
  • Polyethylene Terephthalate (PET): Widely used for bottles (beverages, oils, sauces) due to its lightness, durability, and clarity. It's also highly recyclable.
  • High-Density Polyethylene (HDPE): Often found in milk jugs, juice bottles, and some food containers. It's durable and recyclable.
  • Low-Density Polyethylene (LDPE): Used for flexible packaging like bread bags, produce bags, and some squeezable bottles.
  • Polypropylene (PP): Common for yogurt cups, deli containers, and microwaveable trays due to its heat resistance.
  • Polyvinyl Chloride (PVC): While still used in some applications like cling film and blister packaging, its use in food packaging is declining due to environmental concerns and the availability of alternatives.
• Advantages: Low cost, excellent moisture barrier, lightweight, versatile, direct labeling.
• Challenges: High carbon footprint, widespread pollution, slow biodegradation, and complex recycling for certain types (especially multi-layer films).
• Innovations: The industry is actively developing recycled content plastics (rPET, rHDPE), bio-based plastics (e.g., PLA from corn starch), and compostable plastics to address environmental concerns.

2. Metals: Durable, Protective, and Highly Recyclable

Metal packaging offers exceptional durability, protection, and a high recycling rate, making it a reliable choice for many food products.

• Common Types:
  • Aluminum: Primarily used for beverage cans, foil, and trays. It's lightweight, corrosion-resistant, and infinitely recyclable.
  • Steel (Tinplate & Tin-Free Steel): Used for food cans (e.g., vegetables, fruits, soups). Steel provides excellent strength and barrier properties.
• Advantages: Rigidity, protection against pests, moisture, and contamination, excellent barrier properties, high recyclability, long shelf life.
• Challenges: Higher cost than some plastics, potential for corrosion or reaction with certain acidic foods (often mitigated by internal coatings), heavier than plastic.
• Innovations: Lighter-weight cans, improved coatings for food safety, and enhanced recycling infrastructure.

3. Glass: Premium, Inert, and Aesthetically Pleasing

As one of the oldest forms of food packaging, glass continues to be a premium choice, valued for its inertness, aesthetic appeal, and recyclability.

• Applications: Bottles for oils, juices, carbonated beverages, sauces, jars for preserves, pickles, and baby food.
• Advantages: Corrosion-resistant, extremely food-safe (no chemical migration), appealing aesthetics (allows product visibility), highly hygienic, preserves flavors, infinitely recyclable.
• Challenges: Fragile (breaks easily), heavier than plastic or metal, higher transportation costs, generally more expensive.
• Innovations: Lighter-weight glass, improved strength, and diverse design options.

4. Paper and Wood Derivatives: Sustainable and Versatile

Paper-based packaging, including cardboard and paperboard, is a cornerstone of the food industry, especially for dry goods and secondary packaging.

• Applications: Cereal boxes, frozen food cartons, pizza boxes, paper bags, egg cartons, and some liquid cartons (e.g., milk, juice, often with plastic/foil linings).
• Advantages: Lightweight, relatively low cost, easy to print on, renewable resource, generally recyclable (though coatings can complicate this).
• Challenges: Limited moisture resistance (unless coated), less strength than plastic or metal, can be susceptible to tearing.
• Innovations: Compostable coatings, recycled content paperboard, fiber-based trays as alternatives to plastic, and smart packaging with embedded sensors.

5. Ceramics: Niche, Aesthetic, and Eco-Friendly

Ceramics, made from materials like clay and quartz, offer a unique and often artisanal packaging option.

• Applications: Specialty food items, gourmet products, reusable containers, and some dairy products.
• Advantages: Non-toxic, corrosion-resistant (especially to acids), aesthetically pleasing, can be reusable, often biodegradable.
• Challenges: Brittle (breaks easily), heavier, generally higher cost than plastic or paper, not always food-safe without proper glazing.
• Innovations: Development of more durable and food-safe ceramic glazes, focus on reusable and refillable ceramic systems.

6. Cellulose and Bioplastics: The Future of Sustainable Packaging

Cellulose, a plant fiber, and other bioplastics are at the forefront of sustainable packaging innovation.

• Cellulose Applications: Cellophane sheets, shrink wrap, and some flexible packaging.
• Bioplastics (e.g., PLA, PHA): Used for compostable cups, containers, and films.
• Advantages: Biodegradable (cellulose), compostable (some bioplastics), derived from renewable resources, can offer good barrier properties.
• Challenges: Variable durability, can be more expensive, specific composting conditions often required for bioplastics, limited shelf life for some applications.
• Innovations: Enhanced barrier properties, improved heat resistance, and broader industrial composting infrastructure.

Top 5 Best Practices for Designing Winning Food Packaging

You now know which materials work best for food packaging, but the material makes up only part of the equation when designing effective packaging. Here are some additional best practices to consider when designing food packaging.

1. Prioritize Preservation: Flavor, Texture, and Shelf Life

Your food packaging might look attractive, but if it doesn’t keep your food product fresh, you can forget about winning repeat customers. To win and retain customers, choose packaging materials and a design that, above all else, preserves the texture, taste, and quality of your products while they’re being shipped and stored on the shelf.

Key Considerations:

• Barrier Properties: Does the material protect against oxygen, moisture, light, and odors that can degrade food quality?
• Seal Integrity: Is the seal robust enough to prevent contamination and maintain freshness throughout the product's journey?
• Temperature Control: For refrigerated or frozen goods, does the packaging maintain optimal temperatures?

While our team of experts can consult with you on packaging, they can also help you determine the shelf life of your products. To find an estimation of shelf life that’s accurate and specific, contact us for more information on how we can help.

2. Ensure Uncompromising Food Safety

As important as maintaining the flavor of your products is, there’s something arguably more important—maintaining the safety of your food products. Your packaging needs to resist the wear and tear of traveling; however, the materials used also need to interact well with the food contained inside AND the surrounding air temperature and environment.

Example: Olives, for example, if stored in basic PET plastic packaging, might only last on the shelf for a few weeks and require constant refrigeration. Because the PET packaging lacks an oxygen barrier, it leads to a shorter shelf life for the olives and potential safety risks. In this case, a better option would be olives stored in a laminated composite package with an oxygen barrier, which will remain fresh and safe on the shelf for months at room temperature. Glass, in this case, would also provide a safer option.

To sum it all up, there’s a lot to consider when choosing the right type of packaging that will ensure safety and increase the shelf life of your product. But the good news is that you don’t have to figure this out alone. Medallion Labs offers shelf-life testing that can help you extend shelf life and protect the safety of your products.

3. Design for Versatility and Brand Consistency

You might only have one product that comes in one type of packaging. But if your business does well, you’ll likely want to expand the number of products you offer. And if that’s the case, you’ll need to consider how your brand identity and logo will fit on different sizes and shapes of packaging.

Think Scalability: For instance, if you manufacture a breakfast cereal, the cardboard box used to package your product gives you a lot of flat, printable space to work with. But what if you want to turn that breakfast cereal into a new product, such as a granola bar with the same branding? Well, your logo especially will need to fit on that small area.

So, consider how your logo looks when it goes from large to small. Will your customers recognize it right away? And will your customers recognize your logo if you use it on multiple types of packaging, each with a distinct size and shape? When designing your packaging, design it with a logo and a brand identity that transfers well from one type and size of packaging material to another.

4. Embrace Transparency with Clear, Accurate, and "Clean" Labeling

We all know that packaging needs to include labels that let customers know more about ingredients, best-by dates, potential allergens, and basic nutritional information. However, food labels can look overwhelming and even deter customers from purchasing the product, depending on what they see. For this reason, many food producers now use “clean labels.”

What is a "Clean Label"? While the term “clean label” doesn’t have an official, regulated definition, it generally refers to a food label that contains a shorter list of more recognizable ingredients that customers can easily understand.

Example: Deli ham, for example, might include ingredients such as rice starch, sea salt, and celery powder instead of ingredients that are harder to pronounce or identify, such as sodium phosphates, carrageenan, sodium diacetate, and potassium chloride.

The point is this—clean labels are catching on, which shows that an increasing number of customers are paying attention to labels in the first place. For food producers and brands, this trend signals that they need to pay extra special attention to labeling food accurately and transparently. Labels aren’t just formalities. They’re an essential piece of the food packaging that’s just as important as the material, the branding, or other design elements.

Luckily for food producers, Medallion Labs offers several easy, affordable testing options to ensure food labels—whether they’re listing protein levels, sugar content, fats, allergens, or nutritional facts—accurately reflect the contents of the food contained within the packaging.

5. Consider the Environmental Impact: The Rise of Sustainable Packaging

In today's market, consumers are increasingly conscious of the environmental impact of their purchases. Sustainable packaging is no longer a niche concern but a mainstream expectation.

Key Sustainable Practices:

• Reduce: Minimize the amount of packaging material used.
• Reuse: Design packaging that can be refilled or repurposed by consumers.
• Recycle: Use materials that are widely recyclable and clearly label them.
• Renewable: Opt for materials derived from renewable resources (e.g., plant-based).
• Biodegradable/Compostable: Choose materials that break down naturally at the end of their life cycle, especially for single-use items.

Consumer Perception: Brands that visibly commit to sustainable packaging can significantly enhance their reputation and appeal to environmentally conscious consumers. This might involve using recycled content, designing for easy recycling, or exploring innovative compostable solutions.
