Product Characteristics Environmental Protection

Reduce packing materials used Use packaging materials that are more

environmentally friendly with recycled content Use reusable containers Retain or support services that collect used packaging

and recycle it

Packaging Building-blocks concept

Smallest unit is consumer package Each unit is stocked within the next larger one to

protect the product

Promotional functions of boxes

5-13

Packaging Protective functions of packaging

Enclose materials Restrain materials from undesired movement Separate contents to prevent undesired contact Cushion contents from outside vibrations and shocks Support the weight of identical containers stacked above Position the contents to provide maximum protection Provide for uniform weight distribution Provide exterior surface for labeling Be tamperproof Be safe for consumers or others

Packaging Labeling

Retroflective labels Batch numbers Weight Specific contents Instructions for use Information to allow passage through customs Compliance labeling One- or two-dimensional bar codes Smart labels or RFID labels

Unit Loads in Materials Handling

Basic unit is a pallet or skid Lumber is expensive so firms want pallets

returned Provides cushioning effect in transport Quality of pallets varies widely Chep USA rents pallets in wood or plastic Should be less than 50 pounds—difficult with

plastic Metal also used in closed loop systems

5-23

Unit Loads in Materials Handling

A unit load is one or more boxes secured to a pallet or skid so that boxes can be handled by mechanical means

Rainbow pallet load Unitization describes this type of handling Slip sheet can be used in place of pallet

Saves vertical room Requires more care when moving

5-24

Unit Loads in Materials Handling

Advantages Additional protection Pilferage is discouraged More fragile items can be

stacked inside the load Mechanical devices can

be substituted for hand labor

Disadvantages Provides large quantity

that sometimes is of limited value to resellers dealing in smaller quantities

Must use mechanical or automated device to move

Unit Loads in Materials Handling

An intermodal container holds the unit load Interchangeable among rail, truck, and water

carriers Air carriers usually use irregular shaped

containers made to fit fuselage

Summary

5-30

Materials Handling

Materials handling refers to how the materials or products are handled physically.

How the products are handled depends on whether they are packaged or in bulk

Handling may change the characteristics of the product

Materials Handling in the Supply Chain

Products can move throughout the entire supply chain

Bar codes, two-dimension codes, radio-frequency codes systems facilitate integration throughout the supply chain
