In modern packaging operations, label application speeds can reach 600 units per minute, yet inconsistent adhesion and misalignment continue to cause significant waste—typically 2-3% of production runs. These challenges are magnified when dealing with varied surface materials, environmental conditions, and the need for clean removal during recycling processes.

The fundamental challenge lies in achieving rapid, precise label placement while maintaining consistent adhesion strength across different substrate materials and ensuring labels can be cleanly removed when needed.

This page brings together solutions from recent research—including fast-drying pressure-sensitive adhesives, discontinuous adhesive patterns with spacer-defined adhesion, flexible transfer devices for speed synchronization, and anti-adhesion layers for flattened interfaces. These and other approaches focus on improving application reliability while maintaining compatibility with high-speed production environments and end-of-life recycling requirements.

1. Automated Wafer Packaging System with Drying Agent Bag Shaper and Rotating Roller Labeler

ZHEJIANG DARCET TECHNOLOGY CO LTD, 2025

Automated wafer packaging system that improves efficiency and reduces costs by using devices like a drying agent bag shaper and labeler. The drying agent bag shaper device shapes and pushes the drying agent bags into aluminum foil bags before sealing. This prevents bags from falling apart during packing. The labeler uses a rotating roller to apply labels to wafer boxes and a movable block to attach them securely. The labeler also has a chute to guide the label tape and an elastic member to cushion it. The labeler's arc-shaped pushing blocks correspond to the labeling through-slots to enable uniform labeling and calibration.

2. Label Structure with Anti-Adhesion Layers for Flattened Adhesive Interface

SK Siltron Co., Ltd., SK SILTRON CO LTD, 2024

Label design to prevent printing defects and reduce rework when attaching labels to packaging boxes. The label has anti-adhesion layers between the adhesive and release layers. This prevents steps and unevenness when attaching the label since the adhesive and non-adhesive areas are flattened. The anti-adhesion layers are thin, like 1/20 the thickness of the adhesive. They can contain UV ink for printing on the label surface. This prevents printing issues due to the step between adhesive and non-adhesive areas. The label with flattened surfaces reduces the need for reattaching labels due to poor printing.
