In 1833, the French chemist Anselme Perrin firstly isolated cellulose, a polysaccharide composed of long-chain glucose molecules, from wood.

Cellulose is one of the most abundant renewable resources on Earth, mainly found in plant cell walls, and its microscopic microfibril provides strength and rigidity to plant cell walls, making cellulose an ideal material for manufacturing packaging.

 

Cellulose can be processed into a thin and transparent degradable film: cellophane, which is widely used in the field of environmentally friendly and sustainable packaging solutions.

Let's delve into the world of Cellulose and Cellophane today together.

 

1. How is cellophane made?

• Extraction of cellulose: 

      Cellulose is extracted from cotton, wood or other sustainably harvested natural sources to make a white dissolved pulp with a cellulose content of 92-98%.

• Mercerization: 

      Elevates the ordinary to the extraordinary, turning a simple message into a treasured keepsake.

• Incorporation of carbon disulfide：

      Carbon disulfide is applied to mercerized pulp to form a solution called cellulose xanthate or viscose.

• Film forming:

      The solution is added to a coagulation bath with a mixture of sodium sulfate and dilute sulfuric acid to form a cellulose film.

• Post-treatment:

      The cellulose membrane is washed three times. The sulfur is first removed, then the film is bleached, and finally glycerin is added to improve durability.

 

 The final biodegradable cellophane is completed, after coating, printing and other processing, it can be used in clothing, food, jewelry, electronics, home, gifts, greeting cards and other packaging.

 

 

 

2. What are the green benefits of cellulose packaging bag application?

It is estimated that 320 million tons of plastic are produced globally each year, of which about 8 million tons of plastic waste enters the ocean, and more than 100,000 Marine animals die each year from eating plastic or becoming entangled in plastic. In addition, when plastic breaks down, it creates microplastic particles that are able to penetrate the food chain and eventually affect humans, potentially increasing the risk of heart attack, stroke or death.

 Therefore, degradable packaging materials - a good substitute for plastic packaging bags in cellulose film packaging rooms, is of great significance for protecting the environment and human health.

 

HuiZhou YITO Packaging Co., Ltd. has been deeply engaged in environmental protection and biodegradable industry for 7 years, specializing in providing biodegradable packaging materials.

 

In addition, what are the environmental benefits of cellulose film packaging bags? 

• Safe and sustainable:

      The raw materials of cellophane packaging bags come from bio-based renewable resources, such as cotton, wood, etc., and the ingredients are safe, reducing the long-term burden on the environment

• Biodegradable:

       Cellophane packaging bags can be biodegradable. Tests have shown that uncoated cellulose packaging biodegrades in 28-60 days, while coated products biodegrade in 80-120 days; Uncoated cellophane bags degrade in water within 10 days; If coated, it will take about a month.

• Home compostable:

      Without industrial machinery and equipment, cellophane can be safely placed in the compost pile at home.

 

3. What are the advantages of cellophane bags?

High transparency:    

Cellophane paper bag is a class of paper, compared with other paper classes, cellophane has high transparency.

High safety :

Cellophane bags have non-toxic and tasteless characteristics.

High transparency and gloss :

Cellophane paper bag surface bright. 

Strong tensile and scalability:

The horizontal and longitudinal tensile capacity of the cellophane bag is good.

Printability 

The surface of the cellophane bag is smooth, the printing adaptability is good, and a variety of patterns and text can be printed to increase the beauty of the product and brand recognition.

High temperature resistance:

Cellophane bags can be used in high temperature environments.

 Anti-static and dust-proof :

The cellophane bag is not easy to produce static electricity, so it is not easy to absorb dust, and keep the packaging clean and tidy

 Moisture and oil resistantt - Biodegradable cellophane bags are resistant to moisture and water vapor, as well as oil and fat, making them an excellent choice for products.
