If the earlier facts of food packaging supplies are noticed, then those various containers used to transport products initially, have nowadays taken a back seat. When considering the kind of shipping devices used in the past, the primary focus stood on the manufacturer’s viewpoint. As a matter of fact, till the end of 19th century, generally all shipment processing techniques used easy materials to transport their goods to the market. Those containers were made from clay, cork or wood.
Then in the 20th century there was a drastic shift in the materials used for food packing as the bulk of them were made from glass, metals and paper. Furthermore, another evolution followed as PETE (Polyethylene Terephthalate) material came to the marketplace. This versatile plastic conveniently made bulk quantity of foods available for distribution to consumers in these PETE containers. The benefit was that the Polyethylene could be easily stamped or molded in any imaginable shape. Also, it was inexpensive to produce, thereby making it an economic packaging solution for foods. However, due to the rising environmental safety awareness these days, this solution has made customers more attracted to eco-friendly packaging solutions brought forth from suppliers.
Food packaging is pivotal in conserving food during the entire distribution chain. If not, various food processing hazards can cause contamination due to direct contact with chemical, physical or biological contaminants. Nonetheless, in the past few years, novel food packing concepts and techniques have enhanced the shelf life of various foods. Thus, these measures have improved quality, safety and sustainability to the market. Such advancements have also aided to beverages, pharmaceutical drugs, and other perishable products to be healthier for consumption and sale.
Through the research of material scientists, microbiologists and food chemists, the importance of preserving shelf life during food packaging is mainly related to the packaging agent. This is why the PETE technology has greatly upgrading the packaging industry in recent times.
Few basic functions of Food Packaging
Ideal food packaging protects the barrier from water vapor, oxygen, dust, etc. Permeation is the critical factor when it comes to design. Food packaging may include oxygen absorbers, desiccants to extend the product shelf life. A climate controlled atmosphere is primary for some food packages; this keeps the products fresh, safe and clean.
It may require compression, shock vibration and 食品包裝牌照 temperature when enclosed in single package.
Some small items are grouped together in single package for efficient handling. Powders, granular materials or liquids need containment.
Types of Food Packaging
Food Packaging is essential to keep up the quality of the perishable goods during transit or for extended use. These types of packaging are explained below:
Primary packaging contains the main package in which the food is held for processing.
Secondary packaging holds many primary packages in one box that is completely wrapped.
