Adhesives are substances used to bond materials together, replacing mechanical fasteners like screws, nails, or welding in many applications. Adhesive manufacturing involves the development, formulation, and production of these bonding agents in liquid, solid, or film form.
The industry emerged to meet the need for stronger, lighter, and more versatile bonding methods across construction, packaging, automotive, aerospace, and consumer goods. Today, adhesives are engineered for specific conditions such as heat resistance, water resistance, flexibility, or biodegradability.

Laws and policies affecting adhesive manufacturing
Adhesive production is subject to strict rules to ensure safety, quality, and environmental responsibility. Common policies include:
-
Chemical safety regulations – Agencies like OSHA (USA) and REACH (EU) oversee exposure limits and handling of raw materials.
-
VOC emission limits – Adhesives must comply with regional laws limiting volatile organic compounds.
-
Food-grade adhesive standards – Adhesives used in packaging for food must meet FDA or EFSA requirements.
-
Eco-label certifications – Many countries promote sustainable adhesives through certification schemes.
-
Hazard communication policies – Manufacturers must provide Safety Data Sheets (SDS) for proper use and transport.
These regulations not only protect workers and consumers but also encourage innovation in safer, greener adhesive solutions.
