For grease substances, what is the permeability resistance of BOPP thermosensitive synthetic paper?

For oily substances, the permeability resistance of BOPP thermosensitive synthetic paper depends mainly on the properties of its substrate (such as BOPP film) and the possible coating or treatment process.

First, substrate performance

BOPP film itself has a certain ability to resist oil penetration, which is mainly due to its excellent barrier properties. The molecular structure of BOPP film is tight, which can effectively block the penetration of liquids such as grease. However, it should be noted that the permeability resistance of BOPP film is not absolute, and its performance may be affected by a variety of factors, such as the thickness of the film, tensile strength, crystallinity, etc.

Second, coating or treatment process

To further improve the oil permeability resistance of BOPP thermal synthetic paper, manufacturers may apply a special coating or treatment process to its surface. These coatings or treatment processes can form a dense barrier that further enhances the barrier properties of the material. However, the specific coating or treatment process and its effect on the oil's permeability resistance can vary from manufacturer to manufacturer and product to product.

Third, test and evaluation

In order to accurately evaluate the permeability resistance of BOPP thermal synthetic paper to oil and grease substances, professional testing is usually required. These tests may include simulated grease penetration experiments to assess its permeability resistance by measuring the amount of grease passing through the material over a certain period of time. The test results will directly reflect the practical application effect of the material.

Fourth, conclusion

In summary, the permeability resistance of BOPP thermal synthetic paper to oily substances depends mainly on its substrate properties and possible coating or treatment processes. Although the BOPP film itself has a certain ability to resist oil penetration, the permeability of the specific product may vary by manufacturer and product. Therefore, when selecting and using BOPP thermal synthetic paper, it is recommended to carry out adequate testing and evaluation according to specific needs and application scenarios.
