A laminating machine applies a protective plastic film, either with heat or pressure, to document or items to protect them from damage and wear. Machine sizes and specifications vary significantly, from compact, portable A4 or letter-size laminators (e.g., ~35cm wide) for personal use, to industrial-grade, large-format roll laminators (up to 65cm or more) used in professional print shops and offices. Key features to look for include the maximum material width, number of rollers, lamination speed and temperature, and whether it handles hot, cold, or both types of lamination.
