What are the advantages and disadvantages of BOPP synthetic paper in terms of archival preservation?

In terms of archival preservation, BOPP synthetic paper, as a new material, has its unique advantages and disadvantages compared with traditional paper archival materials. Here's a breakdown of their strengths and weaknesses:

Advantages

1. High mechanical strength:

BOPP synthetic paper has a high tensile strength, tear strength and impact strength, which makes it more resistant to physical wear and damage during long-term preservation, helping to extend the preservation life of archives.

2. Good water, oil and chemical resistance:

Compared to ordinary paper, BOPP synthetic paper has excellent resistance to water, oil and chemicals. These characteristics allow it to maintain good stability in humid, oily or chemical environments, reducing the risk of damage caused by environmental factors.

3. Size stability:

BOPP synthetic paper has good dimensional stability and is not easy to deform and age, which helps to maintain the original appearance and integrity of the file and avoid information distortion or damage caused by paper deformation.

4. Good printing adaptability:

After proper surface treatment, BOPP synthetic paper can have excellent printing effect, making the presentation of file information more clear and beautiful. This is especially important for archives that need to be preserved for a long time and are of great historical value.

5. Environmental protection:

As a kind of plastic paper, BOPP synthetic paper can replace some traditional paper materials, thus reducing the consumption of forest resources and environmental pollution in the papermaking process. This is in line with the current global trend and requirements of environmental protection.

Disadvantages

1. Poor heat resistance:

BOPP synthetic paper has relatively poor heat resistance and may be deformed or damaged in high temperature environments. Therefore, it is necessary to control the ambient temperature during the file preservation process to avoid the impact of high temperature on the file.

2. Folding intolerance:

BOPP synthetic paper is prone to crease lines that are difficult to disappear after folding, which may affect the appearance and integrity of the file. Frequent folding operations should be avoided during file sorting.

3. Price factor:

Compared with traditional paper materials, the production cost of BOPP synthetic paper may be higher, resulting in its price is also relatively expensive. This can add to the cost burden of keeping files. However, with the continuous progress of production technology and the play of scale effects, the price of BOPP synthetic paper is expected to gradually decrease.

4. Long-term storage effect unknown:

Although BOPP synthetic paper has excellent performance in many properties, its application time in the field of archival preservation as a new material is relatively short, and the long-term preservation effect needs further observation and verification. Therefore, long-term reliability needs to be carefully considered when using BOPP synthetic paper to store important archives.

In summary, BOPP synthetic paper has the advantages of high mechanical strength, good water, oil and chemical resistance, stable size, good printing adaptability and environmental protection in archival preservation; However, there are also disadvantages such as poor heat resistance, folding resistance, high price and unknown long-term preservation effect. In practical application, it is necessary to weigh and choose according to the specific situation.
