Will acrylic keychains fade? How to protect the print?

Acrylic keychain prints usually use UV flatbed printing or screen printing. UV printing has good weather resistance, but prolonged direct sunlight can still cause fading. Protection tips: ① Avoid long-term sun exposure; ② Apply a transparent protective film; ③ Choose a double-layer lamination process (print sandwiched between two acrylic layers) for permanent scratch and fade resistance.
