The term 'divide into thin layers' can be summarized by the word 'LAMINATE', which is an 8-letter word. Lamination is a process in which two or more thin layers of material are bonded together with heat and pressure to form a single, thicker layer. It is commonly used to protect documents, photographs, and other materials from damage and wear. Lamination also helps to preserve the quality of the material and can even enhance its appearance.
