Selecting the Right Kinds of Packaging Materials for Frozen Food
Different materials offer unique benefits and drawbacks, so it’s important to understand how each one works. Let’s look at the detailed information!
1. Shrink Film
Shrink film is a widely-used packaging material for frozen foods across global food packaging lines due to its ability to preserve food quality. It is usually made from materials like polyethylene, polyolefin, or PVC, with polyolefin often considered the best choice for food applications.
When heated, shrink film tightly wraps around frozen products, sealing them securely. This creates a strong barrier against moisture, air, and contaminants, which is key to preventing freezer burn and keeping the food fresh.
2. Wax Cardboard
Wax-coated cardboard is a cost-effective, eco-friendly alternative to plastic-based packaging, for packaging frozen foods. The wax coating adds an extra layer of protection, making the cardboard more resistant to moisture, grease, and oil, when exposed to cold and wet conditions.
This packaging is durable and sturdy, making it ideal for frozen items like meats, seafood, and produce. It’s also easy to handle and stack, which is convenient for storage and transport.
3. Glass
It is non-reactive, preserving the original flavor and freshness of food, without absorbing odors or chemicals, making it ideal for gourmet items like ice cream and specialty sauces. Meanwhile, glass is also eco-friendly, as it is reusable and fully recyclable.
However, it is heavier than plastic, which can increase shipping costs, and it can be sensitive to temperature changes. To mitigate these issues, pre-chill glass containers and seal them tightly. Despite these challenges, glass remains a popular choice for luxury packaging, conveying sophistication and appealing to eco-conscious consumers.
4. Aluminum
Commonly used in foil trays for frozen meals like lasagnas and pot pies, aluminum offers excellent barrier properties, blocking light, moisture, and oxygen to keep food fresh and prevent freezer burn.
Aluminum trays are durable and can handle both freezing and cooking temperatures. They often come with a cardboard or wax-coated cardboard lid with foil tabs to ensure a secure seal during shipping.
However, recycling aluminum trays can be challenging due to food residues, which complicate the cleaning process and may lead to some trays ending up in landfills despite their recyclability.
5. Flexible Bags
Made from food-safe plastics, foils, or composite materials, flexible bags effectively address the challenges of freezing while keeping your food in excellent condition.
Flexible bags excel in freshness preservation by protecting against moisture, air, and light, preventing freezer burn, and maintaining the original flavor and texture of the food. Clear flexible bags are commonly used for items like bread and biscuits, allowing visibility while ensuring secure packaging.
They are also cost-effective, being more affordable than rigid containers, which benefits both manufacturers and consumers.
6. Lidding Films
Made from FDA-approved, food-grade plastics, lidding films create a tight seal for various containers, including yogurt cups and frozen meal trays.
These films can be customized with vibrant, full-color graphics, helping your product stand out on the shelf. Many are clear, allowing visibility of the contents, which is a helpful feature for shoppers.
Beyond aesthetics, they’re ideal for packaging frozen fruits, snacks, and ready-to-eat meals, for protecting food from moisture and contaminants.
7. High Barrier Thermoforming Film
Made from advanced plastic resins, high-barrier thermoforming films are flexible enough to mold perfectly to various container shapes and sizes.
Also, these films are known for withstanding bumps and knocks during storage and transport to keep your food in top condition.
They also offer excellent protection against moisture, oxygen, and UV light, so that your food preserve the taste, aroma, and quality
8. IQF Polyethylene
IQF, or “individually quick frozen,” is a fantastic method for freezing food quickly and efficiently. The process involves freezing each piece of food separately at super low temperatures—around 40 degrees below zero Fahrenheit. This speedy freezing helps keep the food’s cell structure intact, so it stays fresh and full of flavor.
After fruits and vegetables, etc., are frozen, it’s usually wrapped in polyethylene to keep it protected and then sent off to the frozen food section of your local supermarket.
9. Skin Film
Skin film is a specialized material designed to wrap frozen food products uniformly and seal them to a printed skin board or corrugated cardboard plate. It is particularly popular for packaging frozen seafood such as salmon and trout. Plus, skin films can be clear for visibility or printed with branding and product info.
Here’s how it works: you place the skin film over the product and then heat it. The heat makes the film shrink snugly around the item, creating a protective “skin” that fits the shape perfectly. This tight wrap keeps out contaminants, moisture, and air. So, your product stays in top condition.
Packaging Solutions for Different Types of Frozen Foods
Selecting the appropriate packaging for frozen foods is crucial to maintaining freshness, flavor, and convenience. Here’s a guide to the best packaging options for different types of frozen foods:
Packaging for Meats and Seafood
For meats and seafood, the focus is on preventing freezer burn and preserving freshness. Vacuum-sealed bags and high barrier thermoforming films are excellent choices, as they create a tight seal that keeps out moisture and air. Skin film is also effective, offering an additional layer of protection and an appealing appearance on store shelves.
Packaging for Fruits and Vegetables
To maintain the texture and nutrients of fruits and vegetables, high-barrier flexible pouches or stand-up pouches are ideal. These pouches protect against moisture and air while being convenient to store and use. Clear bags are great for showcasing the vibrant colors of your frozen produce.
Packaging for Ready-to-Eat Meals
Ready-to-eat meals benefit from packaging that’s both practical and effective. Microwaveable trays with airtight seals or heat-sealed pouches are perfect, allowing for convenient heating directly in the package, to saving time.
Packaging for Baked Goods and Desserts
For frozen baked goods and desserts, choose packaging that keeps items fresh and visually appealing. Clear or printed flexible bags and high barrier films work well, protecting against moisture while allowing visibility. Resealable options are also useful for maintaining freshness after opening.
