Cellophane is a thin, transparent sheet made of regenerated cellulose. Its low permeability to air, oils, greases, bacteria, and liquid water makes it useful for food packaging. Cellophane is highly permeable to water vapour, but may be coated with nitrocellulose lacquer to prevent this.
Cellophane, a thin film of regenerated cellulose, usually transparent, employed primarily as a packaging material. For many years after World War I, cellophane was the only flexible, transparent plastic film available for use in such common items as food wrap and adhesive tape.
Cellophane is a polymeric cellulose film made from the cellulose from wood, cotton, hemp, or other sources. The raw material of choice is called dissolving pulp, which is white like cotton and contains 92%–98% cellulose. The cellulose is dissolved in alkali in a process known as mercerization. It is aged several days.
Cellophane is a crisp, clear, and flexible material used for everything from food wrapping to envelope and cake box windows. It’s often referred to as a “bioplastic” material, so named because it is often made of the cellulose from wood, cotton, hemp, or another plant source.
How is Cellophane produced? The original Cellophane material was made from wood cellulose. Cellophane is thus initially a bioplastics. Nowadays much of what we refer to as “Cellophane” is actually plastic wrap derived from petroleum. PVC has been used since the 1960s and polypropylene since the 1980s.
Cellophane is a transparent film used for packaging. It is known for its tight seal that keeps contents fresh. Its versatility makes it popular for wrapping various items, from food to gifts, providing a protective layer without hiding the product.
The meaning of CELLOPHANE is regenerated cellulose in thin transparent sheets used especially for packaging. How to use cellophane in a sentence.
cellophane, thin, transparent sheet or tube of regenerated cellulose [1]. Cellophane is used in packaging and as a membrane for dialysis [2]. It is sometimes dyed and can be moisture-proofed by a thin coating of pyroxylin [3].
Cellophane, made from regenerated cellulose, has been widely used for food packaging in real life. Cellophane films are transparent and mechanically stiff with excellent stability of dimensions. They are well known as candy wrappings, and also the packaging for cheese, cookies, coffee and chocolates.
One more cellulose derivative which is utilized for the intention of food packing application is cellophane. Cellophane, the thin transparent film, is manufactured by cellulose with the help of the viscose method along with the addition of glycerin to improve flexibility (Helanto et al., 2019).
