Overview
Quality has always been the cornerstone of Chemline Global's success. With more than three decades of manufacturing excellence, we have established one of the most comprehensive adhesive and coating quality assurance systems in the industry. Our products undergo a series of stringent physical, chemical, and performance-based tests to guarantee that every batch meets — and often exceeds — global standards.
From raw material validation to final product dispatch, every step in our production process is governed by a structured quality management framework. Our ISO 9001:2015 and ISO 14001:2015 certifications reflect our commitment to continuous improvement, environmental responsibility, and customer satisfaction.
Chemline's philosophy is simple: if it doesn't meet our standards, it doesn't leave our plant.
Our Testing Infrastructure
Chemline Global houses a state-of-the-art Quality Control & Analytical Laboratory equipped with advanced testing instruments to validate every critical performance parameter. Our testing infrastructure includes:
Tack and Peel Strength Analyzers
Tack and Peel Strength Analyzers measure initial tack and peel force performance for pressure-sensitive adhesives. They help determine how quickly an adhesive grips and how much force is needed to remove it, ensuring consistent bonding for labels, tapes, and self-adhesive applications.
Universal Testing Machines (UTMs)
Universal Testing Machines perform tensile, shear, and compression tests to assess mechanical strength and durability. They simulate real stress conditions to ensure adhesives maintain structural reliability in packaging and industrial bonding applications.
Viscometers and Rheometers
Viscometers and Rheometers analyze viscosity and flow behavior to ensure smooth processing and coating performance. These instruments prevent issues like clogging or uneven spreading and maintain stability during production.
Peel and Bond Strength Equipment
Peel and Bond Strength Equipment checks bonding performance in laminated substrates. It evaluates how well layers stay together under tension and handling, ensuring reliability in flexible packaging and high-strength laminates.
Cobb Value and Kit Test Systems
Cobb and Kit Test Systems measure moisture and grease resistance for coated paper and packaging materials. They ensure barrier performance required for food wraps, cups, takeaway boxes, and eco-friendly packaging solutions.
Spectrophotometers
Spectrophotometers assess color accuracy, opacity, and visual clarity in printed and coated materials. They ensure consistent visual appearance and high-quality branding across production batches.
Environmental Chambers
Environmental Chambers simulate temperature and humidity variations to test adhesive stability under real-world climate conditions. They help validate durability for outdoor, refrigerated, and long-distance logistics applications.
Heat & Aging Ovens
Heat and Aging Ovens accelerate lifecycle testing to evaluate long-term thermal performance. They help predict durability over time and ensure adhesives maintain strength and flexibility under heat exposure.
Adhesion to Multiple Substrates
Testing adhesion across paper, film, foil, and board ensures compatibility and performance consistency. It helps optimize formulations and reduce rejection rates across diverse converting processes.

Let’s Work Together to Build Better Performance
Our team is here to guide you with product recommendations, trials, samples, and technical expertise to support your manufacturing operations.
Stage Wise Quality Control
Raw Material Testing
Every input — resins, polymers, and solvents — is verified for purity, viscosity, and compatibility before entering production. Only certified and approved raw materials move forward.
In-Process Quality Control
Our production lines are monitored in real time with batch-wise sampling to track viscosity, pH, solids content, and polymer dispersion uniformity.
Final Product Testing
The finished adhesive or coating is evaluated for key performance metrics — tack, peel, shear, heat resistance, clarity, and chemical stability — before packaging.
Retention & Documentation
Each batch sample is retained for traceability and verification. Detailed reports are logged digitally within our ERP-integrated QA system to ensure complete transparency.
