IML gate wash and gate darkening are common issues in high-speed IML injection processes. When ink appears washed away or darkened around the injection gate, it’s often caused by excessive shear stress, high IML injection speed, or inadequate heat resistance of the film. Standard BOPP films may deform or allow ink migration under hot melt conditions, resulting in ink wash off injection gate and visible blemishes.
Hardvogue’s heat resistant BOPP IML films are engineered to withstand rapid injection cycles and high temperatures without compromising ink adhesion. Our films maintain consistent print integrity at the gate, preventing ink wash off injection gate and reducing gate darkening, even in demanding molding environments.
For customers, this translates to higher first-pass yields, fewer rejects, and premium-quality packaging with flawless graphics right up to the injection gate. Hardvogue’s solutions ensure that every label stays sharp and vibrant, even under high-speed IML injection speed conditions.
