Anyway, to be clear, our tabs and tape are designed to not block ANY UV light. There are things out there that can work, like transparencies, etc., but just be careful, test different brands, etc. Many either block all (which is easy to tell), or partially block UV light. This means it may take longer to get a full cure.
Unfortunately, there is no way to tell from their packaging whether they block UV, and how much. Sandwich wrap for instance, many of them block partial uv simply because it helps with their primary usage, which is food.
So, if you simply must find solutions not provided by your manufacturer, test, test, test.
