Best Cellophane Film Manufacturer,factory In China
Cellophane is a thin, transparent and glossy film made of regenerated cellulose. It is produced from shredded wood pulp, which is treated with caustic soda. The so-called viscose is subsequently extruded into a bath of dilute sulfuric acid and sodium sulfate to regenerate the cellulose. It is then washed, purified, bleached and plasticized with glycerin to prevent the film from becoming brittle. Often a coating such as PVDC is applied on both sides of the film to provide a better moisture and gas barrier and to make the film heat sealable.
Coated cellophane has low permeability to gasses, good resistance to oils, greases, and water, which makes it suitable for food packaging. It also offers a moderate moisture barrier and is printable with conventional screen and offset printing methods.
Cellophane is fully recyclable and biodegradable in home composting environments, and will typically break down in just a few weeks.

Cellophane is the oldest transparent packaging product used to encase cookies, candies, and nuts. First marketed in the United States in 1924, cellophane was the major packaging film used until the 1960s. In the more environmentally-conscious market of today, cellophane is returning in popularity. As cellophane is 100% biodegradable, it is seen as a more earth-friendly alternative to existing wrappings. Cellophane also has an average water vapor rating and excellent machinability and heat sealability, adding to its current popularity in the food-wrapping market.
Unlike the man-made polymers in plastics, which are largely derived from petroleum, cellophane is a natural polymer made from cellulose, a component of plants and trees. Cellophane is not made from rainforest trees, but rather from trees farmed and harvested specifically for cellophane production.
Cellophane is made by digesting wood and cotton pulps in a series of chemical baths that remove impurities and break the long fiber chains in this raw material. Regenerated as a clear, shiny film, with plasticizing chemicals added for flexibility, cellophane is still comprised largely of crystalline cellulose molecules.
This means that it can be broken down by micro-organisms in the soil just as leaves and plants are. Cellulose belongs to a class of compounds known in organic chemistry as carbohydrates. The base unit of cellulose is the glucose molecule. Thousands of these glucose molecules are brought together in the plant growth cycle to form long chains, termed cellulose. These chains are in turn broken down in the production process to form cellulose film used in either an uncoated or coated form in packaging.
When buried, uncoated cellulose film is generally found to degrade within 10 to 30 days; PVDC-coated film is found to degrade in 90 to 120 days and nitrocellulose-coated cellulose is found to degrade in 60 to 90 days.
Tests have shown that the average total time for complete bio-degradation of cellulose film is from 28 to 60 days for uncoated products, and from 80 to 120 days for coated cellulose products. In lake water, the rate of bio-degradation is 10 days for uncoated film and 30 days for coated cellulose film. Even materials which are thought of as highly degradable, like paper and green leaves, take longer to degrade than cellulose film products. Conversely, plastics, polyvinyl chloride, polyethene, polyethlene terepthatlate, and oriented-polypropylene show almost no sign of degradation after long periods of burial.
Cellophane films are used in a wide variety of packaging applications, including:
– Confectionery, especially twist wrap
– Board lamination
– Soft Cheese
– Tampon wrap
– Variety of industrial applications, such as a base for self-adhesive tapes, a semi-permeable membrane in certain types of batteries and as a release agent in the manufacture of fibreglass and rubber products.
– Food Grade
– Nitrocelullose coated
– PVDC Coated
– Medicine packaging
– Adhesive tapes
– Colored films
Production of Cellophane was high in the 1960th but steadily declined, and today, synthetic plastic films have largely replaced this film. It is, however, still used in food packaging, particularly when high stiffness is preferred to allow bags to stand upright. It is also used for nonfood applications where easy tear is needed.
Different grades are available on the market including uncoated, VC/VA copolymer coated (semi-permeable), nitrocellulose coated (semi-permeable) and PVDC coated cellophane film (good barrier, but not fully biodegradable).
Cellulose films are produced from renewable wood pulp harvested from managed plantations. Cellophane films offer a range of unique attributes which plastic films are unable to equal and can be supplied in a wide range of brilliant colours.
Cellophane is available in different formats, each with proven capabilities and functionality:
Cellophane is also used in transparent pressure-sensitive tape, tubing and many other similar applications.
Our Cellophane film is renowned across the world for its performance in speciality markets including twist-wrapped confectionery, “breathable” packaging for baked goods, “live” yeast and cheese products and Cello film ovenable and microwaveable packaging.
Cellophane film is also used in technically challenging applications such as adhesive tapes, heat-resistant release liners and for battery separators.

Frequently Asked Questions
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 made from a rather complex process. Cellulose from wood or other sources is dissolved in alkali and carbon disulfide to form a viscose solution. The viscose is extruded through a slit into a bath of sulfuric acid and sodium sulfate to reconvert the viscose into cellulose.
Plastic wrap—like the sheer cover used to preserve leftovers—is clingy and feels more like a film. Cellophane, on the other hand, is thicker and markedly stiffer with no cling abilities.
Cellophane has been around for more than 100 years but these days, the product that most people call Cellophane is actually polypropylene. Polypropylene is a thermoplastic polymer, discovered by accident in 1951, and has since become the world's second most widely manufactured synthetic plastic.
Cellophane has some properties similar to plastic, making it a more attractive option for brands wanting to go plastic-free. In terms of disposal cellophane is certainly better than plastic, however it is not suitable for all applications. Cellophane cannot be recycled, and it isn't 100% waterproof.
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 membranes are regenerated transparent cellulose membranes of high hydrophilicity, good mechanical properties, and biodegradability, biocompatibility, and gas barrier characters. The crystallinity and porosity of the membranes have been controlled through the regeneration conditions over the last decades.
If you look through green glass, everything appears green. Green cellophane will only allow green light to pass through it. The cellophane absorbs other colours of light. For example, green light will not pass through red cellophane.
