Efficiency, Sustainability, and Automation — Fully-Automatic WAT Case Sealer: The New Powerhouse in E-Commerce Logistics

In today’s rapidly evolving e-commerce and logistics landscape, traditional manual case sealing methods are no longer sufficient to meet the demands for efficiency, standardization, and sustainable packaging. A growing number of businesses are turning their attention to a new category of equipment — the Fully-Automatic Water-Activated Tape (WAT) Case Sealer, a smart solution that is becoming an essential part of modern packaging lines.

What Is a WAT Case Sealer?

A WAT case sealer is an automated sealing machine designed specifically for use with Water-Activated Tape (WAT), also known as gummed kraft paper tape. Unlike conventional sealers that rely on BOPP plastic tape, this machine uses an automated moistening system to activate the tape’s adhesive properties, enabling fast, clean, and secure sealing.

This type of equipment is especially favored in e-commerce fulfillment centers, cross-border logistics warehouses, and 3PL service providers for its stability, efficiency, and eco-friendly nature.

Key Advantages

Intelligent Moistening System

Built-in humidification automatically activates the tape without manual intervention, ensuring continuous and stable operation.

Strong and Neat Sealing

Water-activated tape offers superior adhesion and tamper-evidence — once sealed, boxes cannot be reopened without leaving visible damage. This ensures security while providing a clean, uniform appearance that enhances brand image.

Eco-Friendly Materials

WAT uses recyclable kraft paper and starch-based adhesive, unlike conventional plastic tape that’s difficult to recycle. This aligns perfectly with the global shift toward sustainable packaging.

Fully Automated Operation

Supports high-speed, one-touch operation, making it ideal for bulk order processing and integration with automated sorting and packing lines. It significantly reduces labor costs and human error.

Application Scenarios

E-commerce Fulfillment Centers (e.g. Shopee, Amazon, JD.com)

Third-Party Logistics (3PL) Automated Packaging Lines

Overseas Warehouse Sorting Centers

Medium-to-Small Parcel Packaging (Food, Daily Goods, Apparel)

Green Packaging Transitions in Manufacturing
