Details of Testing Measures

We select the protective film best suited to your needs based on our extensive experience in protective film applications. We confirm whether the film has good adhesion, and whether it can be peeled off cleanly and easily. We also perform accelerated testing to check the state of the film after extended use, and look for any abnormalities.


  • While we select the protective film best suited to your product, this recommendation is based on a simple testing process and does not guarantee performance.
    Please give proper consideration to the actual conditions in which the product is to be used prior to use.
  • The content and conditions of tests are determined by Sumiron based on the contents of your request. Please submit a separate inquiry if more detailed testing is required.
  • Reports on testing results may be delayed due to the condition of the testing equipment.
  • Although sample boards sent to us will be returned, they cannot be reused after testing.


Please feel free to inquire about our products and the contents of our services.
