Packaging cookies and confections requires a dose of creativity, while ensuring compliance with safety regulations and taking consumer behavior into account. Here, we take a closer look at what a food packaging designer needs to consider when selecting the right materials.
Common Materials Used in Food Packaging
- cardboard
- aluminum
- metal
- plastic
- glass
Aluminum foil packaging helps preserve food products effectively because it can be shaped in various ways and keeps food protected from air and other natural elements. A coordinated packaging set that includes cardboard boxes and cell trays is often used for decorative purposes, particularly for luxury chocolates. The foil is flexible and comes in various thicknesses.
Glass is popular because it offers enhanced protection and can take many forms, although it may break during shipping. However, please keep in mind that glass contains sodium hydroxide, and residual particles may therefore mix with the water in the container if it is stored for an extended period—more than one year.
Plastic is widely used for packaging because of its low cost, practicality, and glossy appearance, but it also generates a large amount of waste, which concerns environmental groups.
In general, once a plastic package is opened, the food should be eaten immediately, unless the package has a zipper closure.
Another major problem with plastic, aside from the fact that it is toxic, is that it can absorb other chemicals. When plastics are released into natural water systems, they can be consumed by fish, which then pass this toxin on to humans when the fish are eaten.
The destruction of marine life is one of the reasons why some governments are advocating for a reduction in plastic use.
Food Security as a Top Priority
Product safety is one of the top concerns for food packaging designers. Food must be preserved for weeks or even months without the contents spoiling. The packaging must also be able to withstand natural elements such as dirt, dust, moisture, mold, and bacteria.
Even a small air leak can cause food to spoil. Plastics will eventually deteriorate, whereas metals offer greater durability. This durability makes metals ideal for food packaging.
Any food that can oxidize quickly requires an airtight container. Thin sheets of aluminum foil will help keep fresh produce well preserved. Cans have low toxicity and are not susceptible to corrosion or rust. Among metals, tin and aluminum offer the best protection against contamination. Storing food at the proper temperature is also an important factor for health reasons.
Growing Recognition of Sustainability
One of the reasons food retailers are adopting more sustainable practices is consumers’ growing interest in options considered more eco-friendly. People are becoming increasingly well-informed about environmental issues and want to be part of the solution, not the problem. Companies in the food packaging industry are demonstrating greater social responsibility by developing more sustainable products and packaging. Sharing these important values with consumers helps them build a relationship of trust with them.
Recyclable materials, such as tinplate and aluminum, have grown in popularity among food packagers. Both of these materials can be reused indefinitely and are flexible enough to take on a wide variety of shapes and sizes. The shape of the packaging is important because it serves as a visual stimulus. A large package conveys different values than a smaller one, just as unusual shapes are perceived as special by consumers compared to more common ones.
Tinplate and aluminum can both be mass-produced quickly and at low cost. Tinplate can be used in various types of airtight lids for aluminum cans.
When it comes to protecting products during transport, tin and aluminum are much more reliable than plastic bags. The extended shelf life is an important factor in distribution planning and sustainability. Sustainability can be measured in many ways, including through quality. Both tinplate and aluminum can be recycled indefinitely without any loss of quality.
Liquids and powders can be packaged in many different ways, which is why flexible materials such as aluminum are well-suited for this purpose. Aluminum is a popular packaging material in the beverage industry because it has the highest recycling rate among materials commonly used for packaging.
Government Compliance
Cutting corners on food packaging safety can result in hefty fines imposed by regulatory agencies in the United States and the European Union. Labeling must not only be accurate and avoid misleading terms, but it must also include specific information about the product and the manufacturer. The primary purpose of these packaging regulations is to protect consumers and prevent them from ingesting spoiled food that poses health risks. It is essential for retailers to protect their reputation, as large-scale product recalls can severely damage a company’s image.
Considerations Regarding Packaging Materials
- chemical composition of the food product
- aesthetic values
- shape, size, weight, and capacity
- heat resistance properties
- type of fastener
Conclusion
Packaging has become a form of marketing in today’s consumer world. It must therefore be attractive enough to catch the eye on a store shelf, while also meeting food safety and shelf-life requirements.
