Frozen food is a lifesaver in today's hectic world, whether pre-cut fruits and veggies, dairy products, or partially-prepared meals. Experts say some frozen foods may even be better for you than their fresh-caught equivalents.
Depending on the amount of moisture present, most frozen pizza boxes wholesale expand by up to nine percent while being frozen. As a result, the materials useful to package frozen foods must sturdy yet adaptable.
The success of your frozen food product hinges on your choice of packaging. When choosing a material for packaging frozen foods, keep in mind the following:
It has to work in temperatures as low as -40 degrees Fahrenheit.
The product's aesthetic value, helps the consumer become familiar with it before purchase and use.
Maintaining pressure to seal, freeze, store, transport, and even cook.
If the frozen food item has any sharp edges, be sure to enclose them securely.
What Are the Different types of Frozen Packaging?
There are different sorts of materials when packing frozen food. But only some common types of custom frozen pizza boxes are:
Polyethylene (PE) film
The quality of Polyethylene (PE) film maintains temperatures of -40 degrees Fahrenheit. In addition, these packagings maintain their mechanical strength and puncture resistance throughout travel, handling, and storage at cold temperatures.
PE derivatives
Frozen food packaging is typically made from plastics like HDPE, LDPE, Polypropylene, etc., all polyethylene derivatives. "packaging" encompasses various materials, from hard to flexible to sometimes even disposable. Plastic is preferable for frozen food because it protects goods from temperature extremes and keeps them warmer.
Polyethylene Terephthalate (PET)
Polyethylene terephthalate (PET) is a material that is resistant to thermal shock. Therefore, it is commonly useful for frozen goods, some of them are cooked food in the microwave or a boiling water.
Cardboard and Laminate Paper
Cardboard and laminate paper are frequently used in the packaging of fast-moving consumer goods (FMCG) such as ice cream, curds, fresh fruit juices, etc. However, once you remove the frozen food from the freezer, the packaging has a short shelf life.
Tin cans
Cans made of tin are the standard packaging for frozen food. However, cheaper plastics like PET and PE are gradually replacing metal cans. Famous businesses continue to utilize tin cans to maintain their brand identity.
What Bring the Packaging Hygiene?
Keeping frozen pizza packaging in a sanitary manner is crucial. Although microbial development is inhibit by deep-freezing, contamination is still undesirable. Manufacturers can integrate cleaning equipment into the packaging and production process. Some clean packaging guidelines are shown below.
Sweep and Dry
Many kinds of bacteria and mold thrive in damp environments. Cleaning the product and its packaging using a dry microfiber cloth at room temperature is known as a dry wipe-down. This not only removes dirt and grime when you plan to transfer frozen foods.
Gentle Scrubbing
Soft-wash is another name for this process. Distilled water or other treatments are sprayed from low-pressure nozzles to eliminate microorganisms. Low-pressure cleaning is standard in large factories with in-house packaging and assembly lines. Medium- and small-sized businesses that produce frozen foods should use this technique to extend their products' shelf life.
Cleaning with Extreme Pressure
High-pressure cleaning can be used on farm-fresh vegetable packages and other food products. Fruits and vegetables are cleaned before packaging to remove any dirt and bacteria that might potentially contaminate the food. High-pressure cleaning machines for frozen food packaging often come with spray nozzles, air-dryers, and hot and cold water temperature settings.
For instance, Bosch Packaging Technology's SVC series of VFFS (vertical forming, filling, and sealing) technology considers regulations regarding the cleanliness of packaged frozen foods.
Labels on frozen food packages
Required FDA label elements include:
• Declaration of identification, or the product's common name;
• Net weight;
• Name and location of the manufacturer
• Nutrient data
When developing labels for custom printed boxes wholesale, choosing materials that can withstand the extreme cold is crucial. Because adhesives are used to keep frozen food together, they must be able to withstand temperatures well below freezing.
The following are examples of labels commonly found on frozen food packaging:
Freezer adhesive-coated blank label sheets made of paper or vinyl.
Labels printing on vinyl sheets using a laser printer are resistant to both extreme cold and high humidity.
You can automatically apply labels on a roll, making them ideal for packing frozen foods.
Roll labels are often printed through thermal transfer, direct thermal, or continuous inkjet/laser.
Labels on frozen pizza packaging boxes is a perfect way of branding. The surfaces of the films, bags, heat-shrink films, and vacuum packs might be smooth or wavy. Therefore, one should consider the box's surface before deciding on the type of label. Label printing options are helpful knowledge that provides complete protection regarding damages.
Wrapping Up
High-quality seals provide complete protection from the elements and also impact the aesthetics of the packaging. The success of the packaging in the marketplace may be significantly affected by color and design choices. In short, pick the best-frozen food packaging materials that stay last.
