Aiming to address your first concern should be your top priority when it comes to packaging frozen foods. With this essential requirement in mind, it gets easier to choose the right packaging materials that do not only protect the types of food that you want to ship but also withstand extreme freezing temperatures.
That said, we are now going to talk about the packaging materials that can protect your frozen foods.
Shrink Film
Shrink film is one of the most popular food packaging materials. Largest food packaging companies across the globe prefer using this film as an inner packaging solution. Three well-known formulations used in the making of plastic shrink film include polyethylene, polyolefin, or poly-vinyl-chloride.
The polyolefin-based shrink film is the best choice when it comes to food packaging. It is a food-grade material, and the FDA approved it. This material performs exceedingly well under freezing temperatures.
Cardboard
Packaging operations would fail miserably in the absence of cardboard. It’s the omnipresence of cardboard that draws its picture in our minds every time we think about packaging. Like other departments, cardboard is used widely in food packaging. Food items that benefit from cardboard packaging include pies, pizzas, cakes, and a large variety of baked as well as raw foods. What makes cardboard one of the best materials for frozen food packaging is that it protects the shrink film and many other types of inner food packaging materials well.
Wax Coated Cardboard
Wax coated cardboard is the perfect packaging solution for the ready frozen foods that just need heat before consumption. Since these boxes are heat-resistant, they remain undamaged when heated in the microwave, allowing foods to become fully consumable.
Glass
It’s a significant property of glass to allow food preservation for the long term. Glass composed of food-grade materials does an even better job in this regard. However, since this material is highly breakable, it is not widely used in the food packaging processes. In most of the regions, people use glass to preserve leftover frozen foods.
Aluminum
Aluminum, being an excellent conductor of heat, promotes quicker food freezing when kept in zero-temperature. That makes aluminum boxes the best containers for the packaging and transportation of frozen foods. These boxes are ideal for the packaging of baked foods. These boxes most commonly use cardboard or wax-coated cardboard sheet as a topper that remains in place through tabs on the sides of boxes.
Flexible packaging
Flexible packaging has become more popular lately, mainly due to its ability to house more of a product while occupying less space, both in the shipment and on the shelf.
These bags are excellent when it comes to packaging frozen foods. There are two variants of flexible packaging available, i.e. standup and pillow pouches. Both of them allow convenient packaging of frozen foods.
Final words
Remember, not every type of material is good for every kind of frozen food. It is important to reach out to packaging experts who can suggest you the right packaging options for your frozen food products.
