A sizable segment of the packaging industry revolves around the food industries in which multi-dimensional packaging is essentially service- based and functionally a system used to allow a manufacturer or a supplier to deliver products safely and with preserved top quality to the consumer at the lowest of cost as possible to the manufacturer. Functions of Packaging The finished form of any type of packaging is influenced by a lot of factors, but logic behind the type of packaging utilized can be achieved by considering various packaging criteria, of which there are five: appearance, protection, cost , function and disposability. 1. Appearance The domination of supermarkets and grocery stores as distributors of food products means that appearance has a significant importance in getting the consumer's attention and thus converting into a sale. Ideally, the package has to represent the product's character and be easily recognized by the consumer. It also has to contain information of the ingredients used to meet legal requirements and also proper instructions for its use and display the product's reasonable price. Basically, packaging must carry a maximum effectiveness as sales aids in order to stimulate the customer's desire to purchase them. 2. Physical Protection Protection required by products differs according to the nature of the product itself, its final destination, the distribution system it undergoes, and the total time frame that protection requires. -Compression, Impact and Vibration All packages must be able to endure the distribution stress that will be encountered in the course of different distribution systems. Compression arises from improper stacking in transportation or storing. If the stacking is unstable, the the risk of damage to the goods is high and so is compromising the product's shelf life. The potential for contamination also rises. Majority of dairy goods are fragile and must be protected to maintain product quality. Damage can result from mishandling of the package, causing leakage and resulting in inlets for moisture to spoil the food product, thus, contaminating the product. Vibration can cause a lot of problems, from abrasion of the outside of the packaging to breakage of its contents. So we can say that the package plays a vital role as a cushion in the transport of sensitive products. -Temperature and Lighting Effects Two major factors to consider in packaging systems are protecting the product against environmental factors, of which temperature is more significant. High temperature effects on a product are usually more serious than low temperature effects. Products that are likely to be negatively affected by high temperatures includes chocolates, which soften, melt and becomes unsellable, fish which rapidly develops a strong off-odor and then becomes inedible; and frozen foods, which thaw out, and then deteriorate biologically after. -Macro-organisms This category of macro-organisms includes rodents and insects. In addition to the loss of product by being eaten by these organisms, there are added loses associated with the contamination of the remaining products. 3. Function The package functions of containing products can be those that concern the end user; ease of opening, display, dispensing and convenience. Package function involves behavior on the packaging line; rigidity of the container and the container weight. 4. Cost Packaging should present the minimum overall cost to the manufacturer but not at the expense of underperforming in the function required, characteristics and properties. Costs include not only the packaging material itself but also the labor, time, materials, transport, and lost product due to failed packaging. A cheaper package may be less expensive in overall costs but, due to inferior performance, may cause losses of products and customers. 5. Disposability The disposal of packaging and its influence on general waste disposal and gathering methods must also be a major focus. The unnecessary use of valuable resources must be reduced as greatly as possible. Waste reduction and management of natural resources must be a priority of the manufacturers and the government in order to secure an economically and environmentally sustainable future. We all hope that the information delivered in this article can aid consumers in the safe purchasing of packaged goods based on the five mentioned factors before buying a product. For even if a packaged product seems not to have sustained any observable damage before it is opened , other irregularities discussed in this article may become evident following its opening.
