Polypropylene can be laser marked, but the result is formulation-sensitive. The practical question is not simply whether a part is labeled \u201cPP\u201d; it is whether the actual resin grade, pigment, filler and additive package can produce the required contrast or surface change without unacceptable melting, gloss change, distortion or residue.<\/p>\n        <p>Natural, white and lightly pigmented PP often need more careful source screening, and some production projects use a laser-sensitive additive or masterbatch to create a wider and more repeatable marking window. Final source selection should be based on the production material, final color and molded surface.<\/p>\n        <div class=\"zr-answer-note\"><strong>Key point<\/strong><p>Do not buy the laser from the polymer name alone.
