Description

[0002] The acrylic sheet upper and lower film alignment process is a technique used during the application of films to acrylic sheets to ensure precise alignment of the upper and lower films, enhancing both aesthetics and functionality. Specifically, a lower film with alignment marks is applied to the bottom surface of the acrylic sheet, while an upper film with alignment marks is pre-applied to the top surface of the acrylic sheet using UV adhesive. The alignment marks on the upper film must be completely aligned with those on the lower film before the UV adhesive on the upper film is cured.
