【 Abstract 】 :
With the enhancement of social environmental awareness, Dongguan Goolien Packaging Technology Co., Ltd. is constantly looking for environmentally friendly, biodegradable petroleum-based plastic substitutes, no doubt cellulose film packaging bags is a good choice.
Discovered in 1833, cellulose is a substance that resides within the cell walls of plants. It consists of long-chain glucose molecules, making it a polysaccharide. When the hydrogen bonds of several cellulose chains join together, they form a substance called microfibril, which is very inflexible and tough. The rigidity of these microfibers makes cellulose a new excellent environmental protection product in the production of packaging bags.
Recycled cellulose bags are usually cellophane (cellulose film), a transparent, thin, biodegradable paper-like material.
1. How is cellulose film packaging bag made?
Cellophane is made from cellulose derived from cotton, wood or other sustainably harvested natural sources. It is originally a white dissolved pulp with a cellulose content of 92-98%. The protocellulose pulp is then converted into cellophane in the following four steps.
①. The cellulose is dissolved in alkali (alkaline ionic salts of alkali metal chemicals) and aged for a few days, this dissolution process is called mercerization.
②. Carbon disulfide is applied to mercerized pulp to form a solution called cellulose xanthate or viscose.
③. Add the solution to a mixture of sodium sulfate and dilute sulfuric acid, which will turn the solution back into cellulose.
④. The cellulose membrane is washed three more times. The sulfur is first removed, then the film is bleached, and finally glycerin is added to improve durability.
The end result is biodegradable cellophane, which is used in the packaging industry such as clothing, toys, electronics, home, gifts, greeting cards, and food.
2.What are the benefits of cellulose film packaging bag application?
Americans use 100 billion plastic bags a year, which requires 12 billion barrels of oil a year. In addition, 100,000 Marine animals are killed by plastic bags every year. Petroleum-based plastic bags take more than 20 years to degrade in the ocean. When plastic breaks down, it creates microplastics that further penetrate the food chain.
With the enhancement of social environmental awareness, Dongguan Goolien Packaging Technology Co., Ltd. is constantly looking for environmentally friendly, biodegradable petroleum-based plastic substitutes, no doubt cellulose film packaging bags is a good choice.
In addition to being an alternative to plastic safety bags, cellulose film bags also have many environmental benefits:
Sustainable and Bio-based: Since cellophane is made from cellulose harvested from plants, cellophane bags are a sustainable product derived from bio-based renewable resources.
Biodegradable: Cellulose film packaging bag is biodegradable. Tests have shown that cellulose packaging will biodegrade within 28-60 days if the product is uncoated; If the product is coated, the cellulose packaging will biodegrade in 80-120 days. Without a coating, it will degrade in water within 10 days; If there is a coating, it will degrade in about a month.
Compostable: Cellophane can also be safely placed in a compost pile at home and does not require industrial facilities to compost.
3. What are the advantages of glass paper bags?
High transparency: Cellophane paper bag is a class of paper, compared with other paper classes, cellophane has high transparency.
Non-toxic and tasteless: glass paper bags have non-toxic and tasteless characteristics.
Good gloss: The surface of the glass paper bag is bright.
Excellent tensile strength: the horizontal and longitudinal tensile strength of the glass paper bag is good.
Excellent flexibility: the horizontal and longitudinal stretching ability of the glass paper bag is good.
High temperature resistance: Cellophane paper bags can be used in high temperature environments.
No static electricity, dust-proof: Glass paper bags have no static electricity, not easy to absorb dust.
Moisture resistance: Biodegradable cellophane bags are resistant to moisture and water vapor, making them an excellent choice for products.
Oil resistance: Cellophane paper bags are naturally resistant to oil and fat.
