6.1 Functions and Types of Packaging

Packaging plays a crucial role in logistics, protecting products and optimizing efficiency. It safeguards items from damage, facilitates handling, and reduces costs. Packaging also aids in identification, marketing, and sustainability efforts throughout the supply chain.

Functions of packaging include protection, efficiency, identification, and marketing. Different levels of packaging serve specific purposes, from primary packaging that directly contacts the product to tertiary packaging for bulk transport. Various materials are used, each with unique properties and applications.

1 of 3

• Packaging serves as a protective barrier safeguarding products from damage, contamination, and environmental factors during storage and transportation
• Facilitates efficient handling and storage by providing standardized shapes and sizes optimizing space utilization in warehouses and transportation vehicles
• Contributes to cost reduction in logistics by minimizing product damage, optimizing load efficiency, and reducing labor requirements in handling
• Incorporates shock absorption, moisture barriers, and temperature control features (bubble wrap, silica gel packets, insulated containers)
  • Protects against physical damage from impacts or vibrations during transit
  • Prevents moisture ingress that could lead to product deterioration
  • Maintains optimal temperature ranges for perishable goods

Identification and Marketing

• Plays a crucial role in product identification and traceability incorporating barcodes, RFID tags, and other tracking technologies
  • Barcodes enable quick scanning and inventory management
  • RFID tags allow real-time tracking of products throughout the supply chain
• Serves as a marketing tool conveying brand identity, product information, and regulatory compliance details to consumers and stakeholders
  • Includes eye-catching designs and logos to attract consumer attention
  • Displays nutritional information, ingredients, and usage instructions
• Packaging design influences consumer purchasing decisions and overall market success
  • Unique shapes or materials can differentiate products on store shelves
  • Premium packaging can convey higher quality or luxury status

Sustainability and Innovation

• Enhances sustainability efforts through the use of recyclable or biodegradable materials reducing waste and environmental impact throughout the supply chain
  • Recyclable materials (cardboard, certain plastics) reduce landfill waste
  • Biodegradable packaging (cornstarch-based plastics) decompose naturally
• Smart packaging technologies actively monitor and maintain product quality during storage and transportation
  • Time-temperature indicators change color if products exceed safe temperature ranges
  • Oxygen scavengers remove oxygen from package interiors extending shelf life
• Standardized packaging formats and labeling systems enhance interoperability across different logistics systems and international supply chains
  • Universal product codes (UPC) enable global product identification
  • Standardized pallet sizes facilitate efficient loading and unloading across various transportation modes

Packaging Levels: Primary vs Tertiary

Primary Packaging

• Primary packaging comes in direct contact with the product providing immediate protection and often serving as the unit of sale to the end consumer
  • Examples include beverage bottles, cereal boxes, and toothpaste tubes
• Serves specific functions in terms of product protection, handling efficiency, and information display throughout the supply chain
  • Protects against contamination and extends shelf life
  • Provides a surface for essential product information and branding
• Influences inventory management, order fulfillment, and distribution strategies in logistics operations
  • Individual units can be easily counted and tracked in inventory systems
  • Enables piece-picking for e-commerce order fulfillment

Secondary Packaging

• Secondary packaging contains multiple units of primary packaged products facilitating handling and distribution within the supply chain
  • Examples include cardboard boxes holding multiple cereal boxes or shrink-wrapped multipacks of beverages
• Enhances protection during transportation and storage
  • Provides an additional layer of cushioning against impacts
  • Keeps multiple primary packages together for easier handling
• Often used for retail display purposes
  • Can be designed for easy shelf stocking and attractive product presentation
  • May include promotional information or bulk pricing details

Tertiary Packaging

• Tertiary packaging, also known as transport packaging, groups secondary packages for bulk handling, warehouse storage, and shipping
  • Examples include pallets, shipping containers, and large corrugated boxes
• Optimizes logistics efficiency and protects products during long-distance transportation
  • Standardized pallet sizes enable efficient loading of trucks and containers
  • Sturdy materials withstand the rigors of mechanical handling and stacking
• Incorporates features for easy identification and tracking in large-scale logistics operations
  • May include large barcodes or RFID tags for quick scanning
  • Often labeled with shipping information and handling instructions

Packaging Materials and Applications

Plastic Packaging

• Plastic packaging including polyethylene, polypropylene, and PET widely used for its versatility, durability, and cost-effectiveness in various industries
  • Polyethylene (shopping bags, food wrap)
  • Polypropylene (microwaveable containers, bottle caps)
  • PET (beverage bottles, food trays)
• Offers excellent barrier properties against moisture and gases
  • Extends shelf life of perishable products
  • Prevents contamination from external elements
• Can be molded into various shapes and sizes
  • Allows for custom designs to fit specific product needs
  • Enables creation of ergonomic shapes for easy handling

Paper and Metal Packaging
