BOPA(Nylon) film is a very easy moisture absorption product, moisture absorption will have an adverse effect on the use, such as size changes lead to inaccurate overprinting, insufficient composite composite strength, foaming etc., so it's necessary to make protection under high humidity environment. Specific attention should be paid to the following issues:
- Do not open the package too early before use.
- Try to use it all at once, and the remaining need to wrap with a good barrier material.
- Ensure the reasonable temperature and humidity in the workshop.
