- All historical changes have had an impact on the way products are bought, consumed and packaged;
- The packaging professionals must always turn their attention to the needs, markets, and conditions of tomorrow;
- Most of goods, not essential to survival, constitute “the good life”;
- In the second half of the 20th century, the proliferation of goods was so high that packaging was forced into an entirely new role: providing the major purchase motivation rather than presenting the goods itself.
- the only method of differentiating was the package itself;
- The less-developed countries do not have adequate land to raise enough food.
- Food goes beyond its natural biological life, spoils, is lost, is infested with insects or eaten by rodents, gets wet in the rain, leaks away or goes uneaten for numerous reasons, all of which sound packaging principles can prevent.
- In a poor economy that can afford no waste, no industries recover secondary value from food by-products.
- Packaging is perceived to be a weapon against world hunger.
d) Environmentalists maintain that recycling is an issue of the environment, not of economics. Money expended to recycle a material represents an investment in fuel, water and other resources. When the resource investment to recover a material exceeds the value of the material recovered, then the harm to the environment is greater, not less.
e) The process of collecting and regenerating a packaging material for further use is a complex one for most materials.
- significant investment in sophisticated equipment.
- While glass is apparently readily identifiable, individual glass compositions as well as different colors make it difficult to get uncontaminated feedstock.
- Paper fiber quality deteriorates with every recycling, and so paper cannot be recycled indefinitely.
- Plastic materials pose a number of serious recycling problems. The plastic industry developed a code for identifying the six most commonly used packaging plastics; it includes an “other” selection as a seventh code (Figure 1.3).
Waste Management and Environmental Issues Figure 1.3 A code identifies the main packaging plastic families. PETE is usually abbreviated PET and V is usually abbreviated PVC. Less commonly used plastics and mixed-plastics constructions are classified as “other”
