Product

High-speed sealing cover tape (SUMILITE™ CSL-Z7304)

This tape is suitable for high-speed sealing and provides sufficient peel-off strength even with a short sealing time, and is resistant to tearing even with 4mm width carrier tape (cover tape width: 2.6mm).

Plants

  • Amagasaki Plant
  • Sumitomo Bakelite (Nantong) Co., Ltd. (China)

Laboratory

  • Film & Sheets Research Laboratory

Features

For high-speed sealing

It achieves sufficient peel-off strength even in a short sealing time, contributing to improved customer's production efficiency.

Reliable film strength even in narrow cover tape width

Its durable materials designed to ensure compliance with the JIS standard (C0806-3) for tensile strength (≤10N), providing a tear-resistant design suitable for 4mm width carrier tapes (cover tape　width: 2.6mm).

Excellent transparency

The low haze makes it easy to see packaged electronic components and semiconductors, and assists better visual camera inspection.

Applications

Electronics and Electrical

Electronic Component Packaging by Tape & Reel style

Cover Tape for Transporting Semiconductor Devices and Electronic Components

Transporting Small Electronic Components (including 0201mm size)
