What You'll Learn
Cellophane is a thin film of regenerated cellulose
Cellophane is a thin, flexible, transparent sheet made of regenerated cellulose. It is one of the first plastics ever invented and is biodegradable. Swiss chemist Jacques E. Brandenberger invented it in the 1900s, popularising it in the United States by using it to wrap candy. Before cellophane, self-service retail was not common. It played a crucial role in developing the self-service model of retail, especially in selling fresh produce and meat.
Cellophane is derived from natural sources such as wood, cotton, hemp, and other organic fibres. It is made by dissolving cellulose in alkali and carbon disulfide to make a solution of liquid viscose. This viscose is then piped to a casting machine, where it is extruded through a slit into an acid bath, coagulating into a film and reconverting to cellulose. The film is then washed, bleached, and treated with softening materials before being passed through dryers.
Cellophane is highly impermeable to air, oils, greases, bacteria, and liquid water, making it ideal for food packaging. It is also used in transparent pressure-sensitive tape, tubing, and various industrial applications. However, it is not fully waterproof and cannot be recycled.
The term "cellophane" comes from combining "cellulose" with "diaphane," the French word for "translucent." While the original production process used toxic carbon disulfide, a newer lyocell process can produce cellulose film without it. Cellophane is compostable and can be obtained from biomaterials, making it a better choice than conventional plastics for light-duty, single-use applications.

It was invented by Swiss chemist Jacques E. Brandenberger in the 1900s
Cellophane is a thin, transparent sheet of plastic that was invented by Swiss chemist Jacques E. Brandenberger in 1908. Brandenberger coined the term by combining cellulose with diaphane, the French word for "translucent." It is made from regenerated cellulose, which is typically derived from natural sources such as wood, cotton, hemp, or other organic fibres.
Cellophane was the first see-through packaging and one of the first plastics. It is also biodegradable, which sets it apart from conventional plastics. In 1912, Whitman's candy company popularized the material in the United States by using it to wrap candy. This played a crucial role in developing the self-service model of retail, as customers could now see the quality of pre-packaged fresh foods before purchase.
Before cellophane, self-service retail was not common. The development of cellophane allowed manufacturers and retailers to manipulate the appearance of products by controlling oxygen and moisture levels. It also enabled them to package a variety of food items, as well as industrial applications such as a base for self-adhesive tapes, a semi-permeable membrane in some batteries, and as a release agent in the manufacture of fibreglass and rubber products.
While cellophane has environmental advantages over conventional plastics, it is not without its drawbacks. The production of cellophane requires toxic carbon disulfide, and it could release methane, a powerful global-warming gas, if disposed of in a landfill that lacks a methane recovery system. Additionally, cellophane is not fully waterproof or recyclable.

It is biodegradable and compostable
Cellophane is a thin, transparent sheet made from regenerated cellulose. While it is not a traditional plastic, it is often grouped with plastics due to its similar functional properties. Cellophane is unique among plastic-like materials because it is biodegradable and compostable. This means that it can be broken down by microorganisms in the environment, leaving no harmful residues behind. The biodegradability of cellophane is due to the fact that it is made from cellulose, a natural polymer that is the main component of plant cell walls. Cellulose is a long-chain polymer that is highly stable and resistant to breakdown by most organisms. However, certain microorganisms, such as bacteria and fungi, have the ability to produce enzymes that can break down cellulose into smaller components that can be used as a food source.
When cellophane is composted, these microorganisms go to work, breaking down the cellulose chains and using the resulting sugars to fuel their growth and metabolism. This process results in the complete breakdown of the cellophane into carbon dioxide, water, and biomass (the microorganisms themselves). This makes cellophane a truly biodegradable and compostable material, which can be safely returned to the environment without causing harm or contributing to the growing problem of plastic pollution. While cellophane is biodegradable, it is important to note that it is not readily biodegradable, meaning that it may take several months or even years for it to fully break down, depending on the conditions.
To ensure proper composting of cellophane, it is important to follow guidelines for proper disposal. This typically involves placing cellophane in a compost bin or pile where it can be mixed with other organic waste materials such as food scraps and yard waste. Moisture, oxygen, and a balanced mixture of carbon-rich and nitrogen-rich materials are necessary to create an optimal environment for the microorganisms to break down the cellophane effectively. Additionally, maintaining a suitable temperature range (typically between 55-70 degrees Celsius) and regularly turning the compost pile can help accelerate the composting process.
While cellophane is biodegradable and compostable, not all forms of cellophane are created equal. Some types of cellophane may be treated with chemicals or additives during manufacturing to enhance their properties, such as strength or flexibility. These additives may impact the biodegradability of the material. It is important to check with the manufacturer or supplier to ensure that the cellophane you are using is free from such additives if full biodegradability is a requirement for your specific application. Proper disposal methods, such as industrial composting facilities, may also be recommended to ensure complete biodegradation under controlled conditions.
Overall, cellophane is a unique and environmentally friendly alternative to traditional plastics due to its biodegradability and compostability. By understanding the conditions required for proper composting and being mindful of any additives used during manufacturing, we can maximize the benefits of using cellophane and contribute to a more sustainable future.

It is not fully waterproof and cannot be recycled
Cellophane is a thin, transparent sheet made of regenerated cellulose. It was invented by Swiss chemist Jacques E. Brandenberger in the 1900s and was the first see-through packaging. It is one of the first plastics and is biodegradable and compostable.
While cellophane is a better packaging option than conventional plastics, it is not fully waterproof and cannot be recycled. It is highly permeable to water vapour, which means that it cannot be used for packaging products that require moisture-proofing. This makes cellophane unsuitable for certain applications, such as packaging items that need to be protected from moisture.
Cellophane is also not recyclable, which is a significant drawback in terms of its end-of-life impact. It is important to consider the intended use and expected lifecycle of packaging materials to ensure that they match the product's needs and to avoid unnecessary waste.
To make cellophane waterproof, it can be coated with nitrocellulose lacquer. This treatment was developed by chemist William Hale Charch and made cellophane suitable for packaging products that required moisture-proofing. However, even with this treatment, cellophane remains unable to be recycled.
Overall, while cellophane has some advantageous properties, its lack of full waterproof capabilities and recyclability are significant limitations that impact its suitability for certain applications and its environmental impact.

It is used for packaging a variety of food items and industrial applications
Cellophane is a thin, transparent film made from regenerated cellulose. It was invented in the early 1900s by Swiss chemist Jacques E. Brandenberger, who was inspired by the way a tablecloth repelled liquid when wine was spilled on it. Brandenberger initially attempted to create a waterproof coating for viscose cloth, but the resulting fabric was too stiff. However, he discovered that the transparent cellulose coating could be peeled off the backing cloth, creating a flexible and unbroken sheet.
Cellophane was the first see-through packaging and one of the first plastics. It is also biodegradable and compostable. In 1912, Whitman's candy company popularised the material in the United States by using it to wrap candy. Cellophane played a crucial role in developing the self-service model of retail, as customers could see the quality of pre-packaged fresh foods before purchase.
Today, cellophane is still used for packaging a variety of food items, including baked goods, meat, fresh vegetables, bread, cookies, candy, granola, and greasy or oily foods. It is also used for non-food items such as soaps, crafts, and gift bags. Cellophane is ideal for these applications because it has low permeability to air, grease, and bacteria, and it can be made in various thicknesses and colours.
In addition to food packaging, cellophane has several industrial applications. It is used as a base for self-adhesive tapes such as Sellotape and Scotch Tape, as a semi-permeable membrane in certain types of batteries, and as a release agent in the manufacture of fibreglass and rubber products. Cellophane is also the most popular material for cigar packaging due to its permeability to water vapour, allowing cigars to "breathe" while wrapped and in storage.
