9 Different Types of Food Packaging Methods

by | Jun 21, 2024 | durapak-blog

While the aroma of freshly baked bread or the appealing colours of ripe berries may steal our attention, food packaging plays a crucial role in the packaging industry. It’s not just about keeping food contained; it’s about ensuring that what gets to our tables is secure, healthy, visually pleasing, and easily accessible.

Through this blog, let’s understand how the good we love reaches our plates and discover the significance and types of food packaging methods that are best regarding safety, appetising, and ready-to-be-savoured.

Understanding Food Packaging

Why is packing so necessary? Consumers interact with a product for the first time through its packaging. The story is housed inside its outer covering. The technique of packing a product can impact how it appears on store shelves, how long it stays fresh, and how much waste it produces. Understanding its nuances helps us appreciate the complex processes that enable our culinary experiences. 

What is Food packaging?

The methods used to enclose, preserve, and showcase food products for distribution and consumption are referred to as food packaging. Techniques like modified atmosphere packaging protect food from contamination, physical damage, and environmental variables and increase its lifespan.

It also dramatically impacts branding and marketing, influencing customer decisions through attractive designs.

Types of food packaging methods

Nine types of packaging are used while packing and distributing food. They are the following,

1. Primary Packaging:

The initial layer that comes into touch with the food product is referred to as primary packaging. It has a significant impact on maintaining the contents’ freshness and quality. Primary packaging can be made of a variety of materials, including plastics, glass, metals, and paper. 

Glass jars, for instance, are frequently used for sauces and preserves because they offer an airtight environment to avoid spoiling. Due to their portability and lightweight, plastic containers are popular and are appropriate for foods like yoghurt and deli meats.

2. Modified Atmosphere Packaging (MAP):

MAP is a method for extending the lifespan of perishable goods by changing the gaseous atmosphere inside a packaging. This technique uses a mixture of gases, such as nitrogen, carbon dioxide, and oxygen, to replace the air inside the package. 

The growth of spoilage germs and oxidation can be slowed down by altering the gas composition, keeping the food fresher for longer. MAP is frequently employed for things like fresh fruit, meat, and bakery goods.

For instance, a salad is placed in a sealed container with an altered atmospheric composition. The air inside the container is replaced with a specific gas mixture that slows down the growth of bacteria and preserves the freshness of the vegetables. This method extends the shelf life of the salad by maintaining its colour, texture, and nutritional value.

3. Vacuum Packaging:

Before closing the item, vacuum packing involves removing air from it. This procedure helps limit the development of spoilage bacteria, which depend on oxygen to survive. The lower air pressure also preserves the food’s texture and flavour.

 Products like processed meats, cheese, and coffee are frequently packaged in vacuum-sealed containers to preserve their quality and increase shelf life.

4. Aseptic Packaging:

Aseptic packaging includes sterilising the food product and the packaging material separately before they are mixed and sealed. By doing this, the contents are preserved without the need for refrigeration or preservatives while remaining microorganism-free. 

Juices, soups, and sauces are examples of liquid items frequently packaged aseptically to preserve their nutritional content for long periods at room temperature.

5. Secondary Packaging:

The outer covering that covers and safeguards the primary packaging is referred to as secondary packaging. It provides additional protection during handling and shipping and a way of branding and information sharing. Secondary packing frequently takes the shape of corrugated containers, shrink wrap, and cardboard boxes. This layer enhances the entire customer experience and offers a consistent aesthetic.

Consider a cardboard box for cereal. This box contains individual cereal bags and essential information such as the cereal’s nutritional facts, ingredients, and branding. While the primary packaging (the cereal bags) keeps the cereal fresh, the secondary packaging adds an extra layer of protection during transportation, helps consumers identify the product on the shelf, and provides essential details.

6. Sustainable Packaging:

In recent years, the food sector has made significant progress towards using more eco-friendly packaging options. Sustainable packaging employs recyclable, compostable, or biodegradable materials while reducing waste and carbon impact. Sustainable packaging techniques, such as reusable containers and plant-based polymers, are rising in popularity as more customers place an emphasis on environmentally friendly products.

A compostable food container is an excellent example. Made from biodegradable materials like plant-based plastics or paper, this container breaks down naturally without leaving harmful waste behind. It’s often used for takeout food, allowing consumers to enjoy their meals and then dispose of the packaging in an eco-friendly manner, reducing the burden on landfills.

7. Active Packaging:

Active packaging goes beyond passive protection and preservation. It contains elements that interact with the food product to increase its safety or shelf life. For instance, oxygen absorbers can be used in packaging to minimise oxidation and preserve the product’s flavour and colour. Similarly, antimicrobial packaging has ingredients that prevent bacteria and other diseases from growing, helping maintain food safety.

8. Smart Packaging:

With technological improvements, smart packaging has become a game-changer for the food business. Sensors, indicators, or QR codes are included in this kind of packaging to offer real-time data on the product’s freshness, temperature history, and legitimacy. Customers may access this information through their cell phones, enabling them to make educated decisions.

A QR code on a milk carton, when scanned with a smartphone, provides instant access to detailed information about the milk’s origin, production date, expiration date, and nutritional content. This empowers consumers to make informed choices and adds transparency to the food supply chain.

9. Retort Packaging:

To ensure product safety and lifespan without refrigeration, retort packaging includes heat-processing food in a sealed container to kill unwanted germs. Soups, sauces, and meals that are ready to eat frequently employ this technique. Retort pouches are a standard option for customers and producers since they are lightweight and low-energy.

Ready-to-eat meals are often packaged in retort pouches. The food is sealed within the bag and then heated to a specific temperature to destroy harmful microorganisms. This method ensures the product’s safety and extends its shelf life without requiring refrigeration. Retort pouches are lightweight and convenient for both manufacturers and consumers, making them a popular choice for preserved foods.

Did you know? The choice of packaging material can significantly impact the preservation of food’s freshness. Certain packaging materials possess selective permeability properties, allowing specific gases, such as oxygen and carbon dioxide, to pass through at controlled rates. The permeability of the packaging film is adjusted to provide the ideal gas composition inside the food container in modified atmosphere packaging (MAP), which makes use of this feature.

Significance of food packaging

Food packaging plays a crucial role in various aspects of the food industry, ensuring that products are safe, appealing, and accessible to consumers. The following main points underline the significance of food packaging:
