With types like polyethylene and polypropylene, plastics cater to a wide array of packaging needs — from flexible pouches to rigid containers. While plastics have impacted the industry in many positive ways, the overall environmental cost is a pressing matter; and the industry is seeking more sustainable alternatives.

Biodegradable and Compostable Materials

Biodegradable and compostable materials are changing the landscape in packaging. Compostability lets materials like polylactic acid (PLA) and plastics made from starch be composted, taking the waste burden off our planet in the long term. These materials are becoming increasingly popular in eco-friendly packaging.

Flexible Packaging

Flexible packaging using multiple layers of different materials provides lightweight solutions with excellent barrier properties. These pouches and wraps are preferred for convenience products and are space-efficient. They usually mix plastic, aluminum, and paper to get the desired qualities.

Edible Packaging

The development of edible materials takes packaging to an innovative frontier, where packaging acts as well as can be consumed without waste. The seaweed or rice paper examples are the most common and are used in niche markets or on specific food products.

Understanding Primary, Secondary, and Tertiary Packaging

The activities surrounding food packaging can be described as a modern art and it would be so without a knack of understanding the hierarchy of levels of packaging as this would lack the efficiency in getting the final product to consumers and satisfying them in the long run. Every hierarchy performs a specific duty geared towards ensuring that the items are secured and ready for market distribution.

Primary Packaging

Primary packaging is the first level of packaging that touches the product and its protection. This type of packaging is made to keep the product safe but also to give the customer instructions and easy-use features. For instance, a pouch of cereal or a cup of yogurt serves as an introductory barrier to yogurt ads while providing low diet information. The primary focus of primary packaging is on the product and its interactions with the consumer, ensuring safety and usability even after it has been bought.

Secondary Packaging

Secondary packaging provides an extra level that combines several primary packages into a single enclosed container and thus facilitates easier handling and protects the packages as well as displaying them for retail. This level functions as a buffer during transport and offers branding opportunities and product information at a glance. For example, a cardboard box that holds several cereal pouches to ship. Primary packaging is directed towards the consumer target market while secondary packaging is controlled by logistics and marketing giving these packages a protective appeal and structural support during transportation.

Tertiary Packaging

Tertiary packaging finds its application in the storage of products in quantity mainly during the distribution of the products. Large volumes of the product are most commonly packed into log pallets, shrink films, or into a large box for ease of movement and storage. It serves the basic need of securing products from any form of destruction when transported over a long distance.
