Core size refers to the diameter of a laminating film roll‘s inner cardboard tube. Roll film is most commonly found in 1″, 2.25″ or 3″ core sizes.
Roll laminating film with a 1″ core is often used with machines like the LEDCO Educator or EZ Lam School Budget laminator in educational settings and some smaller print shops. Films with either a 2.25″ or 3″ core are typically used with heavy duty machines like the Royal Sovereign RSH-1151 45″ Wide Format Laminator or LEDCO Signmaster in commercial print shops.
When ordering roll film, do check your machine’s specifications to make sure the mandrel can accommodate the film. If you’re not sure which roll film is appropriate for your machine or project, ask us within the comment section – we’re happy to help you!
