GBC A3 Stitched Laminating Carriers are premium, commercial-grade protection sheets engineered to ensure flawless lamination while safeguarding your machine's internal components. Measuring perfectly for A3-sized applications, these heavy-duty carriers are bound with a stitched edge construction to prevent document shifting during the thermal binding process. Designed to pass smoothly through the heated rollers of a laminator, they act as a thermal barrier that prevents excess adhesive from bleeding out and wrapping around the rollers, eliminating costly jams and downtime. These carriers also distribute heat evenly across the film surface, eliminating bubbling, cloudiness, and wrinkles on delicate prints, photography, and office signage.
