1. Equipment Overview
The GREENS MACHINERY Water-Based Acrylic Pressure Sensitive Adhesive (PSA) Production Line is a turnkey system engineered specifically for manufacturing adhesives used in BOPP packaging tape and PE protective film. Built around acrylic emulsion polymerization, the line integrates deionized water treatment, monomer pre-emulsification, initiator dosing, and reactor polymerization into one continuous workflow.
All product-contact parts are stainless steel, delivering acid/alkali resistance, high-temperature stability, and corrosion resistance for long polymerization cycles. The system is available in capacities of 3, 5, 10, 20, and 40 tons, and can be custom-configured to your production requirements.

3. Process Flow
The line follows a standard acrylic emulsion polymerization sequence:
- Water Purification — RO unit produces deionized water, stored in separate cold and hot tanks;
- Pre-Emulsification — Butyl acrylate and other monomers are mixed with water and emulsifier in the emulsification tank;
- Initiator Dosing — Initial and dropping initiators are fed per the process curve to control polymerization rate;
- Polymerization — The reactor’s paddle + baffle + spray system ensures uniform heat transfer, with a condenser for reflux control;
- Discharge & Filtration — Pneumatic diaphragm pump transfers the finished water-based acrylic PSA after filtration.
4. Equipment Highlights
- Elevated Platform Design — Reactors mounted on a steel platform with safety railings and stairs for easy operation and maintenance;
- Dedicated Pump Sets — Separate pumps for hot DI water, cooling water circulation, monomer transfer, dosing circulation, and reactor discharge (pneumatic diaphragm);
- Reactor Internal Structure — Paddle + baffle + spray combination with condenser ensures stable polymerization temperature;
- Central Control Console — Reactor unit operation console manages temperature, stirring, and pump/valve control from one panel;
- Formula & Technical Support — Complete production formula and on-site guidance from engineers with 30+ years of experience.
5. Applications
The water-based acrylic PSA produced by this line is used for:
- BOPP packaging tape coating
- PE protective film coating
