Historical Development
Monopentahydroxymethyl ethane is an important organic chemical product, and its history can be traced back to the end of the 19th century. Westerners pioneered its method to synthesize formaldehyde and ethanol in alkaline media. The process was crude and simple, and the yield was limited. By the 20th century, the industry had refined its approach and gradually perfected it. The catalytic conditions were more and more elegant, and the purity of the purification was greatly improved. Later, with the needs of emerging fields such as polymer industry, coatings, and lubricants, global production gradually became a system. After the reform and opening up, Middle Earth began to introduce Western technology on a large scale. After decades of hard work, the process has kept pace with the international.

What are the packaging specifications of Mono-Pentaerythritol?
Mono-Pentaerythritol, called monohydroxy pentaerythritol in Chinese, is a common raw material in modern chemical industry. Its form is mostly white crystal or powder, soluble in water, less soluble in alcohol, stable in nature, easy to store and transport. Regarding the specifications of its packaging, due to the multi-terminal application field and different market needs, the standards are different.
There are several types of packaging in this world. The most common one is a woven bag with a net weight of 25 kilograms, lined with polyethylene plastic bags to prevent moisture intrusion. This form is conducive to general trade and small and medium-sized use. The second is a large-capacity package with 50 kilograms, and it is also in the form of a composite bag. However, due to its large size, it is suitable for centralized transportation to factories with large quantities. Large-scale chemical enterprises may need larger specifications, and commonly use tonne bags with a net weight of 500 kilograms to one ton, that is, container plastic woven bags. The inner layer is isolated by polyethylene film, and the outer layer is solid. It can be loaded and unloaded by lifting machines, which is very convenient for long-distance transshipment such as sea and land transportation.
In addition to the above paper-plastic composite bags or tonne bags, there are occasionally plastic drums and steel drums, which are mostly used for customers with special requirements. Their specifications vary, from 25 kilograms per barrel for small ones to 100 kilograms and 200 kilograms for large ones. They are all customized according to the buyer. If it needs to be stored for a long time, it is often placed in a cool and dry place, protected from light and moisture. At the same time, the mouth of the packaging bag needs to be tightly sealed to prevent moisture absorption and agglomeration Some high-purity products still have small packaging forms, with a net weight ranging from one kilogram to five kilograms, which are mostly used in laboratories or small batches for trial.
Summarize the packaging specifications of Mono-Pentaerythritol, where 25 kilograms and 50 kilograms of medium bags are the most common, bulk trade is mostly used in ton bags, and special channels are occasionally seen in small bags and barrels. Packaging is in accordance with international transportation, environmental protection and safety standards, which not only guarantees quality, but also handles circulation. This system has become a common practice in the industry, and it is distributed between China and foreign trade.

Large-scale chemical enterprises may need larger specifications, and commonly use tonne bags with a net weight of 500 kilograms to one ton, that is, container plastic woven bags. The inner layer is isolated by polyethylene film, and the outer layer is solid. It can be loaded and unloaded by lifting machines, which is very convenient for long-distance transshipment such as sea and land transportation.
In addition to the above paper-plastic composite bags or tonne bags, there are occasionally plastic drums and steel drums, which are mostly used for customers with special requirements. Their specifications vary, from 25 kilograms per barrel for small ones to 100 kilograms and 200 kilograms for large ones. They are all customized according to the buyer. If it needs to be stored for a long time, it is often placed in a cool and dry place, protected from light and moisture. At the same time, the mouth of the packaging bag needs to be tightly sealed to prevent moisture absorption and agglomeration Some high-purity products still have small packaging forms, with a net weight ranging from one kilogram to five kilograms, which are mostly used in laboratories or small batches for trial.
Summarize the packaging specifications of Mono-Pentaerythritol, where 25 kilograms and 50 kilograms of medium bags are the most common, bulk trade is mostly used in ton bags, and special channels are occasionally seen in small bags and barrels. Packaging is in accordance with international transportation, environmental protection and safety standards, which not only guarantees quality, but also handles circulation. This system has become a common practice in the industry, and it is distributed between China and foreign trade.
