Food packaging is packaging that has been designed specifically for food.
The main goal of food packaging is to protect goods from tampering and biological, chemical, and physical deterioration from harvest to consumption.
Earliest food packaging can be traced back to 6000 BC when food preservation was centered around bees' wax to protect food from the elements.
The early 1800s gave rise to the tin and the first cardboard boxes used in commercial food packaging like canned meats and vegetables and cardboard boxes for cereals.
More recently, the early 1900s saw the introduction of cellophane and plastic 'saran' wrap, which is still used today. For food processors, barrier packaging and shelf life extension remain a priority. Our history of packaging page helps to highlight changes in packaging historically.
Food packaging is critical for conveying the correct information, protecting the product, and extending shelf life as much as possible.
However, these aren't the only crucial aspects of food packaging - practicality also plays a role in design. Packaging needs to be as recyclable as possible and be malleable enough to make transit via truck, boat, or plane economically viable. For marketers, packaging needs to be eye-catching and stand out on shelves, or the design may help to add perceived value to the product.
Packaging is used for many reasons, including:
Common plastics used in food packaging include:
Many materials are coextruded together to obtain the desired properties. Additives can also be included to change the packaging color, composition, and barrier properties.
The desire to go green has led many food organizations to push for recyclable or biodegradable materials.
Options like bioplastic, card, paper, and glass are desired to try and reduce the amount of plastic left in a landfill site.
The EPA also outlines plans to boost the country's recycling rate to 50% by 2030, showing a significant change in attitude among consumers and organizations.
Food packaging comes in all shapes, sizes, structures, and styles - each tailored to hold different food products based on their needs.
The most common types of food packaging are:
Flexible Barrier Packaging - Extending storage times with an oxygen barrier is a prevalent worldwide packaging option.
Boxes - Corrugated boxes are used for packaging exterior master packs of cereals and other products, but chipboard boxes are very popular in the food industry.
Cans and bottles - Aluminum cans, plastic, and glass bottles are all popular ways to store and transport beverages and foods with high liquid content.
Wrappers - Many wrappers have barrier properties. Flow wrapping is a common form of wrap packaging that is sealed and blocks oxygen. Other candy and paper wrappers may not seal or provide an oxygen barrier.
Poly Bags - LLDPE food-safe bags are commonly used for short-term food packaging. Easy to print on, and many closure options are available.
Trays - Can be made from many different materials; popular trays for food packaging are paperboard, foam, and polypropylene.
Cartons - Paperboard cartons are a sustainable option for liquids and powders.
Each form of packaging is designed to protect and preserve different types of food. Foods are sealed to protect from tampering, contamination, and spoilage.
Below are some examples of packaging ideas for a range of different products.
Preserving food and preventing the growth of nasty bacteria is a critical part of the packaging. If people consume food that has been improperly stored, the consequences can be life-threatening.Different foods have varying degrees of susceptibility to bacterial growth. For example, meat and fish can only be kept at room temperature for 2 hours. At this point, dangerous levels of potentially life-threatening bacteria accumulate on them.
On the other hand, dried goods – like certain fruits, seeds, and nuts – last weeks before they go bad.Luckily, modern-day preservation techniques let us preserve the riskiest foods far beyond their natural shelf life, reducing spoilage and lowering food prices.
Some of the most effective preservation solutions used today are:
Packaging for tea ultimately varies depending on the type. Tea bags can often be stored in a small cardboard box, foil sleeve, or paper pouch. Tin cans are commonly used for loose-leaf tea as they're effective against moisture and contamination, which can ruin the taste. Coffee packaging can vary depending on consumer preference.
Whole bean coffee packaging often uses foil barrier bags with a vent hole. The vent hole allows gases to escape the pouch when released by the bean but prevents air from entering the bag. Ground coffee is sold in cans, foil pouches or bags, and coated kraft bags. With the popularity of pods, they are often sold in sealed bags or sleeves to help extend freshness.
Raw and cooked meat products need an oxygen barrier to slow down the bacteria and accelerate decomposition. Traditionally, raw meat is packaged on a polypropylene tray and wrapped with thin sheets of meat film to prevent leaks and contact with other products. Many meat producers are moving toward a sealable barrier shrink packaging for less mess and longer storage times. Some larger meat cuts can be stored in thick airtight heat-shrink materials for the freezer and refrigerated storage.
Vegetables Vegetables and fruit with a durable peel or skin can typically be transported in crates, bulk bins, mesh bags, and other containers. Leafy vegetables that can quickly perish when exposed to open air and warmer temperatures are more likely to be packaged in a polyethylene plastic exterior. Frozen vegetables are also packaged in a PE material, often with some barrier properties to help protect from freezer burn.
Cheeses need to be kept chilled and wrapped to maintain their freshness. Special cheese bags and film are the preferred packaging for cheeses. For large blocks and wheels, special barrier shrink film can extend shelf life. For shorter-term storage, special cheese film can provide an oxygen and moisture barrier.
Frozen pizza and other freezer meals use materials to protect from freezer burn during storage. Thicker polyolefin shrink film is popular with many pizza brands for packaging entire pizzas for frozen storage. Other frozen meals use a lip-seal film and rigid container to protect during frozen storage. Shorter-term packaging for pizza often uses a thinner pizza shrink film to wrap over the pizza and cardboard tray. This is a popular option for take-and-bake storage. Some smaller pizzas are packaged in vacuum-style packaging with custom-made containers, but it is not as common as the other options listed.
Many machines are used to safely and securely package and ship food products. The equipment commonly found in many food processing plants are:
Corrugated cardboard and paper-based products are often regarded as the materials best for the environment.
Because the material is highly recyclable, completely biodegradable, cheap to manufacture, lightweight, and durable, it's widely recognized as the best all-around material. Glass and tin cans are also highly recyclable and excellent options when available. Rigid food containers are also now becoming more recyclable. If ever in doubt, look at the bottom of the container to view which recycling classification the container falls under. Any codes 1-3 will be more recyclable than codes 4-7.
Many food packaging plastics are co-extruded, making recycling and biodegradability difficult. Most tin beverage cans even have a polymer lining that can complicate recycling.
Biodegradable food packaging has rapidly become necessary to tackle global landfill and waste management concerns.
This means switching to alternative packaging solutions from sustainable sources.
The best biodegradable packaging solutions for product packaging are:
The FDA has become increasingly stringent in its guidelines for labels on food packaging. To remain compliant, food processing companies face an increased range of rules and regulations that need to be followed. In addition to federal regulations, it is crucial to be aware of state and local requirements. All should be considered before committing to a final packaging design and process.
Some of the FDA's more critical requirements are:
If they don't, food companies run the risk of legal trouble and putting consumers' health at risk.
To meet requirements, several factors can be considered about the food product being packaged. The FDA offers a helpful food labeling guide to be sure every guideline is considered.
