What Are The Materials Used In Frozen Food Packaging Boxes?

 

And it all starts with choosing the right substrates. Your packing materials must keep food fresh while also being leak-proof and long-lasting. They must also be grease resistant and able to withstand high-temperature changes. Fortunately, various custom frozen food boxes choices are available to assist firms in meeting a range of different business objectives, including sustainability.
Businesses must consider consumer preferences and purchasing habits while developing frozen food innovations. In recent years, there has been a spike in interest in a variety of frozen food items, many of which are environmentally friendly.

Materials for custom Frozen Food Boxes

Custom frozen fish boxes packaging materials range from petroleum-based goods like shrink wrap and individually quick frozen (IQF) polyethylene to cardboard and aluminum. While some are more sustainable than others, they all have advantages. Let's take a look at some of the more prevalent substrate possibilities.

• Paperboard with Natural Kraft Coating (CNK)

It has a surface layer made of hardwood fibers and a clay-based coating that is ideal for printing. CNN’s low-caliper construction allows it to retain a rigid shape while weighing less than equivalent substrates, lowering costs. CNK is an excellent alternative if you need a material with a very versatile structure. 

Paperboard with Poly-Coating

Poly-coated substrates are extremely useful for goods that require direct contact with food and a grease barrier. They are a popular food packaging material because they are heat resistant, which is a desirable attribute for microwaved products.

Notably, poly-coated paperboard is not recyclable, which should cause environmentally conscious brands to reconsider using it as a frozen food packaging material. Shrink wrap is a heat-sealed film that covers and protects a product fast. If you're an environmentally conscious company, you might want to examine other more sustainable alternatives, if not be mindful of how much shrink wrap you use in frozen food.

The US Department of Agriculture considers aluminum to be a food-grade substance as well. It has the extra benefit of being recyclable; nevertheless, recycling entails scrubbing remaining food off the aluminum, which some consumers may be unwilling to undertake.

Custom Frozen Food Boxes and Sustainability

Simply put, more consumers are looking for food companies that will assist them in making more sustainable purchases. According to a Think with Google marketing insights research from October 2021, 82% of consumers prioritize sustainability.

So, what does this mean for the custom frozen foods boxes? Frozen food manufacturers can meet their sustainability goals by incorporating a few sustainable substrate options into their packaging solutions, in addition to applying right-size packaging principles, localizing supply chains, and reducing their carbon footprint.

Recycled Post-Consumer Paperboard

By incorporating post-consumer recycled paperboard into packaging (and indicating it on the label), you can demonstrate to consumers your commitment to sustainability while also reaping the benefits of paperboard packaging.

Bio-Polymers

When compared to petroleum-based plastic wrappers, biodegradable protein substitutes, such as casein, are far more effective at keeping out oxygen and other pollutants. Your food stays fresher for longer, strengthening your brand as a sustainability leader.

High consumer demand has fueled the packaging industry's fast expansion. Many businesses discover a cost-effective way to stock up on frozen food cartons in large quantities. Furthermore, the increasing popularity of this strategy is the increasing demand for Frozen Pizza Boxes.

Similarly, flexible packaging is critical for keeping perishable goods fresh. When shopping for frozen foods, carefully read the labels. Food for freezing is frequently packaged in cardboard or plastic containers. At wholesale prices, you may get a traditional assortment of frozen food cartons.

Select the application's custom frozen food boxes

While there are various forms of frozen food packaging, plastic film is frequently chosen because of its:

• Excellent strength-to-weight ratio

• Resistance to low temperatures

• Capability to defend against external threats

The criteria for printing on plastic frozen food packaging substrates, however, differ from those for printing on aluminum, tin, glass, and metal. When printing on plastic, this is not the case. Before you go to print, understand your frozen food boxes materials and their printing needs, especially if you're working with bespoke frozen food packaging or styles with irregular surfaces. Furthermore, you should select a dependable and diverse printing process, such as flex, that is supported by sturdy print materials, such as elastomer sleeves.
