Adhesive Laminating & Coating
Glenroy’s adhesive laminating and coating machinery delivers some of the most advanced capabilities in the flexible packaging industry. Our equipment features modern application and drying technology that few adhesive laminating and coating lines offer, allowing us to bond a wide range of substrates and engineer flexible packaging structures that perform under demanding conditions.
Advanced Adhesive Laminating Capabilities
Expertise in both extrusion and adhesive laminating allows Glenroy to produce a wide range of packaging film laminations, including hybrid structures that combine both methods in a single package. Our high-performance adhesive system bonds a wide range of substrates and delivers flexible packaging films that withstand aggressive contents, from chemically demanding cleaners to high-barrier food packaging.
Built for Performance on the Filling Line
Glenroy’s flexible packaging films are known for superior roll profile, which translates directly into better performance on your line. Our adhesive-laminated films deliver:
- Faster run speeds and consistent performance on form, fill, and seal lines, improving efficiency and reducing downtime
- Roll-to-roll consistency that eliminates the need for constant adjustments on filling equipment
- Reliable performance down to the roll core, reducing material scrap and waste
This is what separates a well-engineered laminating adhesive from a generic one. The adhesive system has to hold up not just on the shelf but during high-speed converting, filling, and sealing across the full supply chain.
Applications Across Various Industries
Glenroy’s adhesive laminating and coating equipment can handle a wide range of flexible packaging structures, including films, aluminum foil, paper, and metallized substrates. This versatility supports applications across various industries:
- Food packaging requiring shelf life extension and chemical resistance
- Pharmaceutical and medical packaging requiring tight regulatory compliance
- Nutraceuticals and dietary supplements
- Personal care and cosmetic items
- Household and chemical products
Quality Procedures and Production Specs
Adhesive-laminated or coated flexible packaging films are available in wide widths. To deliver superior roll profile and consistency, we run rigorous quality procedures including:
- Basis weight analysis
- Adhesion analysis
- Peel and seal analysis (where applicable)
- Coating weight analysis
Heat-Seal Coating
Glenroy also provides heat-seal coating, widely used in the pharmaceutical and medical industries. Our advanced adhesive coating machinery delivers consistent, repeatable results for peelable lidding films, foil pouches, and sealed medical device packages.
Why Brands Trust Glenroy for Adhesive Laminating & Coating
For over 60 years, leading brands have relied on Glenroy to engineer flexible packaging that performs. Our U.S.-based manufacturing, in-house technical expertise, and rigorous quality systems deliver laminations and coatings that meet your packaging needs from prototype through full production. Our packaging engineers work directly with you to specify the right adhesive system, substrate combination, and coating weight for your product, balancing performance, regulatory compliance, supply chain reliability, and implementation costs.
From general-purpose laminations to high-performance applications requiring chemical resistance and retort capability, Glenroy delivers the technical depth and production consistency the flexible packaging market demands.
Adhesive Laminating & Coating of Flexible Packaging
Frequently Asked Questions
What are laminating adhesives for flexible packaging?
Laminating adhesives are the bonding systems used to join two or more layers of substrate (such as plastic film, aluminum foil, or paper) into a single flexible packaging structure. The adhesive determines how well the layers stay bonded under heat, chemicals, moisture, and high-speed converting.
What is the difference between adhesive laminating and extrusion laminating?
Adhesive laminating bonds layers together using a liquid adhesive that is applied, dried, and cured to form a permanent bond. Extrusion laminating uses molten polymer extruded between two substrates to bond them. Unlike many flexible packaging converters, Glenroy offers both processes in-house and can combine them in hybrid film structures, giving brands access to the best characteristics of each lamination method in a single package.
Which industries use Glenroy's adhesive laminating and coating capabilities?
Glenroy’s adhesive laminating and coating capabilities serve brands across the flexible packaging industry, including food packaging, pharmaceutical and medical device packaging, nutraceuticals, personal care, household and chemical products, and pet food. The same equipment supports general-purpose laminations and high-performance applications such as retort and chemically aggressive products.
What is heat-seal coating used for?
Heat-seal coating applies an adhesive layer to a substrate so it can be sealed to another material using heat and pressure. It is widely used in the pharmaceutical and medical device industry for peelable lidding films, blister packaging, and sterile packaging applications. Glenroy’s adhesive coating machinery can apply a wide range of coatings and coating weights to match the exact seal performance each application requires.
How does Glenroy support food safety and regulatory compliance?
Glenroy’s quality and regulatory systems ensure that all laminating adhesives and coatings meet applicable food safety and regulatory standards. Our packaging engineers work with customers to understand their specific compliance requirements and select adhesive systems that meet FDA and other industry-specific guidelines for their products.
Can adhesive laminating support sustainable and recyclable packaging?
Yes. The right adhesive system is a key part of designing recyclable flexible packaging structures. Glenroy engineers all-polyethylene laminations and other recyclable solutions that qualify for the How2Recycle® store drop-off program, supporting the circular economy and helping brands meet sustainability goals without giving up barrier protection or shelf life.
