Key Terms Pallets Recycled content Slip sheet Key Terms Unitization Unit loads
6
Product Characteristics
Physical Characteristics Density of bulk materials Ability to withstand exposure to elements Respiration Chemical Characteristics Incompatible products Products requiring chemicals Characteristics must be made known to consumers

Product Characteristics
Hazardous Cargo Explosives Compressed gases Flammable liquids Oxidizers Poisons Radioactive materials Corrosive materials
9
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
10
Product Characteristics
Packaging Scrap Disposal Pallet shredder Metric System usage

12
Packaging Building-blocks concept Promotional functions of boxes
Smallest unit is consumer package Each unit is stocked within the next larger one to protect the product Promotional functions of boxes
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 Package testing Vibrations Dropping Horizontal impacts
Compression Overexposure to extreme temperatures or moisture Rough handling

18
Packaging A package system requires 3 types of information to design
Severity of the distribution environment Fragility of the product Performance characteristics of various cushion materials
19
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

22
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
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
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

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
31
Materials Handling Principles
Orientation Requirements Integrated system Standardization Just-in-time Unit load Minimum travel Space utilization Ergonomics Energy Ecology Mechanization
32
Materials Handling Principles
Automation Flexibility Simplification Gravity Safety Computerization Systems flow Layout Cost Maintenance Obsolescence Team solution
33
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
