How to Prevent Wrinkles in Thick Double-Sided Adhesive Tape Structures | Celadon Tech

Wrinkle formation is a common issue when manufacturing thick double-sided adhesive tapes. As adhesive thickness increases, internal stresses within the roll structure become more difficult to control.Many manufacturers experience problems such as liner distortion, telescoping, edge lifting, or wrinkle formation after rewinding and storage. These defects may not be immediately visible during production but often appear later during transportation, warehousing, or converting.Celadon developed a specialized tape architecture designed specifically for thick adhesive applications.The structure combines dual release liners, a PET carrier film, and adhesive layers exceeding 95μm on both sides. In addition, winding tension profiles and lamination conditions are optimized to balance internal stresses throughout the roll.This approach significantly reduces wrinkle risk while improving roll appearance and handling performance.For converters and end users, the benefits include improved die-cutting stability, reduced production interruptions, lower scrap rates, and enhanced product consistency.The technology is particularly suitable for semiconductor materials, EVA bonding systems, industrial laminates, and high-build transfer tape constructions.
