2. INTRODUCTION
• Packaging materials serve several important functions in the transportation,
storage, and protection of goods. They are designed to ensure that products
reach consumers in optimal condition while providing information and
convenience.
• The Packaging Institute International defines packaging as the enclosure of
products, items or packages in a wrapped pouch, bag, box, cup, tray, can,
tube, bottle or other container form
• Containment
• Protection and/or preservation
• Communications
• Utility or Performance
If the device or container performs one or more of these functions it is
considered a package. Dr. P. Dineshkumar / AP / AGE / KNCET 2

3. The selection of a packaging, will depend on
1. Existing economic ability.
2. Production and distribution efficiency.
3. Retailing pattern.
4. Consumer preferences.
5. Ecological aspects.

6. • Protection: One of the primary functions of packaging materials is to protect the enclosed
product from damage during handling, transportation, and storage. For example, cushioning
materials like foam or bubble wrap can absorb shocks, while sturdy boxes or containers provide
structural support
• Containment: Packaging materials serve to contain and hold the product securely in place,
preventing movement or shifting that could lead to damage.
• Preservation: Certain packaging materials are designed to extend the shelf life of products by
providing a protective environment. Vacuum-sealed packaging can also remove air and inhibit
the growth of bacteria, further preserving the product
• Information: Packaging materials often feature labels, tags, or printed information that
provides crucial details about the product. Such information helps consumers make informed
decisions and ensures product safety and regulatory compliance.
Dr. P. Dineshkumar / AP / AGE / KNCET 6

7. • Convenience: Packaging materials also aim to enhance convenience for both manufacturers and
consumers. Easy-to-open features, such as tear strips or zip locks, facilitate product access.
Packaging that is lightweight and stackable optimizes storage and transportation efficiency.
• Legal and Regulatory Compliance: Packaging materials must adhere to various legal and
regulatory requirements. Packaging materials need to meet these standards to ensure consumer
safety, protect the environment, and comply with relevant laws.
• Environmental Sustainability: Packaging materials are increasingly being designed with
consideration for environmental impact. Additionally, lightweight packaging reduces material
consumption and transportation energy requirements.
Dr. P. Dineshkumar / AP / AGE / KNCET 7

8. • Marketing and Branding: Packaging materials play a crucial role in marketing and
branding efforts. Well-designed packaging can create an good connection with
consumers and influence purchase decisions.
• Convenience in Distribution: Packaging materials facilitate efficient distribution by
enabling easy handling, stacking, and transportation of products.
• Tamper Resistance: Packaging materials can incorporate features that provide
evidence of tampering or unauthorized access to the product. These help ensure
product safety, integrity, and consumer trust by indicating if the package has been
compromised.
• Differentiation and Shelf Appeal: Packaging materials contribute to the visual
appeal and differentiation of products on store shelves. Packaging materials also aid
in effectively communicating the product's benefits and target audience through
visual cues Dr. P. Dineshkumar / AP / AGE / KNCET 8

9. • Consumer Convenience and User Experience: Packaging materials can enhance the overall
consumer experience by offering convenience features like easy opening, portion control, or
reseal ability.
• Shelf Organization and Retail Efficiency: Packaging materials assist in organizing products
on store shelves for efficient stocking and display. They can incorporate features like
standardized dimensions, barcode labels, or hanging tabs for easy identification and handling in
retail environments.
• Product Information and Communication: Packaging materials serve as a platform for
product communication and branding. In addition to mandatory labeling information, they may
include promotional messages, storytelling elements, or QR codes that direct consumers to
further product information or online resources.
• Cost Efficiency: Packaging materials play a role in cost management for manufacturers.
Optimizing packaging design, material selection, and production processes can contribute to
cost savings while still meeting functional requirements.
