Food packaging systems and inventions of food packaging machines play a critical role in keeping the US food supply among the safest in the world.

Basically, packaging preserves the nutrition of food processing after it has been completed, allowing foods to travel safely for vast distances from their point of origin while being wholesome at the time of consumption.

Researchers and analysts discovered that around 100 million tons of food are wasted annually in the EU, accounting for nearly 30% of the agri-food supply chain, resulting in significant environmental effects.

This led to the estimate that food waste would exceed 200 million tons by 2050, requiring a 50% increase in world food supplies. Even if the relationship between shelf-life and food waste is not simple, a large portion of food loss is due to the short shelf-life of fresh produce due to its biological nature.

As a result, food packaging has proven to be a strategy that may help prevent foods from excessive waste while also protecting food storage. But what are the functions and applications of Food Packaging? Let’s have a look at them:

Use/Roles of Food Packaging

The primary functions of food packaging and food packaging systems are to protect food items from outside influences and damage, to enclose the food, and to give consumers ingredient and nutritional information. Secondary roles of increasing importance include traceability, convenience, and tamper detection (we’ll explain better as we progress).

As a result, the purpose of food packaging is to hold food in a cost-effective manner that meets industry needs and consumer expectations, maintains food safety, and has the least possible environmental impact. The following are the other roles of food packaging:

  • Food Waste Reduction and Containment

Any assessment of the environmental impact of food packaging must take into account the beneficial effects of reduced food waste throughout the supply chain. Significant food waste has been recorded in several nations, ranging from 25% for food grains to 50% for fruits and vegetables, similar to the above-mentioned EU study.

As a result, poor preservation/protection, storage, and transportation have been identified as causes of food waste. Packaging decreases total waste by increasing the shelf-life of foods and thereby extending their usability.

  • Food Protection and Preservation

Food packaging can slow product deterioration, retain the benefits of processing, extend shelf life, and maintain or improve food quality and safety. Packaging protects against three key types of external influences: chemical, biological, and physical.

Chemical protection reduces compositional changes caused by external effects such as gas (usual oxygen), moisture (gain or loss), or light exposure (visible, infrared, or ultraviolet).

Biological protection creates a barrier between microbes (pathogens and spoilers), insects, rodents, and other animals, preventing sickness and spoilage.

Physical protection guards against mechanical damage and includes cushioning against shock and vibration during distribution. Physical barriers, which are typically made of paperboard and corrugated materials, are resistant to impacts, abrasions, and crushing damage, making them safe and commonly used for shipping containers and packaging for delicate items such as eggs and fresh fruits.

  • Convenience and Portability

Package innovation is strongly influenced by convenience factors such as ease of access, handling and disposal, product visibility, resealability, and microwave capability.

As a result, the packaging is critical in reducing the effort required to prepare and serve food items. Oven-safe trays, boil-in bags, and microwaveable packaging allow consumers to cook a whole meal with no effort.

However, such features give value and competitive advantages to products, but they can also affect the amount and type of packaging trash that must be disposed of.

  • Marketing and Branding

A product’s package is its face, and it is typically the only product exposure buyers get before purchasing. As a result, in a competitive setting, distinctive or inventive packaging can enhance sales in line with branding.

The package may be created to improve the product’s image and/or to set it apart from the competition. Larger labels, for example, could be used to accommodate recipes.

  • Product Information

Packaging also offers consumers information and package labeling. For example, a food package complies with legal requirements for product identification, nutritional value, ingredient declaration, net weight, and manufacturer information.

Furthermore, the food package usually contains vital product information such as cooking instructions, brand identification, and pricing. All of these improvements may have an impact on proper trash disposal as well.

Now that we’ve established the purpose and functions of food packaging, let’s look at the various types of food packaging equipment available. There are several categories and types of food packaging machines used to execute various forms of packaging materials appropriate for the type of food for which it was created.

The following are the numerous types of food packaging machines available in the industry:

Types of Food Packaging Machine

  • Food Packaging Machine for Bundling

Food packaging equipment for bundling is extremely popular and is frequently employed by numerous food suppliers. It may hold a large amount of food before it is banded or wrapped as a single bundle.

It is also known as the banding machine. It can also be used to pack little things like stick candies or individually wrapped hot dogs that can be bundled together for economic reasons.

  • Vacuum Packaging Machine for Food

It is one of the most efficient food packing technologies because it eliminates air, keeping food fresh. Aerobic bacteria, which are responsible for the rapid deterioration of foods, do not grow or are immobilized in this environment.

  • Biscuit Packaging Machine

Another sort of food packaging equipment is the biscuit packaging machine. It is commonly equipped with an electronic digital temperature controller to achieve the necessary temperature with high precision during the food packing process.

It contributes to the food’s maximum freshness. The most intriguing feature of this machine is that packaged products are closely monitored by its automatic feed counter, which displays the number of objects packed by the machine. This makes it easy for food manufacturers to track daily industrial output.

  • Bagging Machinery

It is widely used in numerous food processing factories in China. Food is packed in bags, sacks, and pouches in this example. This bagging machine is frequently used to pack cereals and powdered commodities like milk powder and sugar.

  • Capping and Cover Machine

Capping machines are used among food syrup and beverage suppliers. This equipment is not used only to pack food items, but rather in tandem with other food packaging equipment.

  • Closing Machine

These closure devices are also widespread in many food processing plants. This tool is used to secure metal wires around a food bag or pouch.

  • Accumulation Machinery

The accumulation machinery is used side by side with the capping machine. This machine enables optimal bottle alignment for systematic and ordered food filling. It is used in the production of soda and bottled water.


The basic aim of sustainable packaging must remain to ensure food safety and preservation, wholesomeness, and quality.

Therefore, the environmental impact of packaging waste can be reduced by carefully selecting materials, following the relevant criteria, and assessing packaging expectations in terms of environmental effects.

Knowledgeable efforts by businesses, government, and consumers will promote ongoing development, and an awareness of the functional aspects of packaging will prevent many well-intentioned but ill-advised solutions that fail to account for both pre-and post-consumer packaging variables.

As a result, there are numerous types of food packaging methods and machines in the sector. But the most important element to consider is finding one that meets your needs in terms of the types of foods being produced, so assisting you in assuring optimum quality products with fully extended storage and life that will help store food and prevent food waste.
