How flexible Performance Packaging prevents food spoilage

The world have witnessed a variety of food packaging materials from wood, glass, paper bags, aluminium and glass. The exploitation of oil in the twentieth century brought among many other changes a new revolutionary material, plastic.  From daily tasks to our most usual needs, plastics preserves food and provides performance characteristics that meet the needs of the consumer at all levels. The invention of plastic have benefited millions of people, reduced food waste, improved the quality of life, and prevented diseases caused by food contamination.

Why we need Food Packaging IN OUR DAILY LIFE

Food items face exposure to environmental and natural factors, which quickens spoilage. Along the value chain and at home, plastic packaging protects food by slowing down the spoilage process to preserve the overall quality of the food over a certain duration, known as shelf life. Food packaging provides a protective barrier between the food and the environment and controls the exchange of oxygen and carbon dioxide, thereby preventing microbial contamination, as well as protection from water vapour, oxygen, odorous substances and light, etc.


The different FORMS of food spoilage

Microbial spoilage:  deterioration due to the activity and presence of microorganisms (bacteria yeast and molds). This is the most important type of deterioration since it may affect the safety of food.

Chemical spoilage: undesirable changes due to chemical reactions between the natural components of foods and elements such as oxygen.

Enzymatic spoilage:  undesirable changes that occur in food, due to organic molecules called enzymes that quickens chemical reaction and loss of the natural qualities (taste, aroma, texture) of food. One of the most common is the browning that occurring in fruits and vegetables.

Moisture transfer: The excessive loss or gain of moisture affect foods causes spoilage in the overall quality of food items. These food items lose desirable texture characteristics through softening, toughening, breakdown, swelling or shrinkage.
