Cellulose film has been manufactured continuously since the ancient times and is still used today. Cellophane is actually a slender, translucent pane finished of regenerated fiber. This thin cellophane does not allow air, oils, greases, bacteria and water to enter so this makes it functional for packaging of things which are perishable like food items. Cellulose which is the basic unit of the cellophane bags belongs to a class of compounds often known as carbohydrates; the core unit of cellulose is the glucose molecule. It is the combination of several glucose molecules that are often brought together to form a polymer and from that polymer sheet cellophane bags are made. Cellophane bags sales have dwindled in the recent era due to alternative packaging options like the plastic bags. However, cellophane itself is completely biodegradable, and that has increased its fame as a food packaging. The typical total time for the complete bio-degradation of the cellulose films ranges from 30 to 50 days. There are many industrial applications of cellophane, for example: a base for such self-adhesive tapes, a semi-permeable membrane in a firm type of battery, as dialysis tubing and as a discharge mediator in the manufacture of fiberglass and rubber products. Cellophane is the most popular material for manufacturing food packaging; its permeability to moisture makes cellophane the just right product for this application as food storage material. Cellophane bags is the best and are most-in-demand as compared to the other varieties available, mostly because of its being gifted with the capacity of storing the edible items, such as the baked items, or be it chocolates, cakes, and the ultimate preference for the packaging of slippery or oily foodstuffs. Cellophane bags are even today considered a high packaging material, used for all types of products, used especially for the storage of food. When it comes to the lifting of containers, as well as for the secured packaging especially in the agro-products, chemicals, food-grains, fertilizer materials and medical packaging plastic bags are widely used for the purpose as they can withstand the weight of heavy materials. Mostly preferred in the bakery industry, plastic bags as well as the cellophane bags also have versatility which can be easily expand from their bottom, when it comes to the presentations that need to be attractive. Having expandable sides to add depth to the cellophane bags, they are indeed advantageous in the packaging industry. Cellophane bags with wide bottom like the gusseted bags are often considered a high-grade packaging material and also it is widely using for coffee packaging in the world.
