Paper & Plastic Mailers
Innovative adhesive and application technologies for manufacturers building the next generation of paper and plastic mailers.
Mailer manufacturing is changing quickly. E-commerce growth, automation, packaging-on-demand, new films and papers, sustainability goals, and higher expectations for closure security are creating both challenges and opportunities.
Our adhesive and equipment divisions have developed meaningful experience in this market. We support pressure-sensitive peel-and-seal closures for high-volume plastic and paper mailers, precision hot melt application systems, release-liner processes, and water-based heat-seal coatings used in advanced in-line production.
We work alongside manufacturers to improve existing processes and develop capabilities that can create new products, customers, and market opportunities.
Adhesive and Equipment Expertise in One Conversation
Mailer performance depends on more than selecting a pressure-sensitive adhesive or heat-seal coating. Pattern placement, cutoff, coat weight, web handling, release liner, temperature, speed, controls, and finished-package requirements all matter.
Our adhesive and equipment teams can work together to evaluate the complete process. That combination has allowed us to help customers improve existing operations and introduce manufacturing technologies that create meaningful competitive advantages.
Bring Us into the Conversation Early
The best time to discuss a new mailer, closure, coating, or production method is before every decision has already been made. Tell us what you produce today, what you want to produce tomorrow, and what stands in the way.
Applications We Support
You May Know These Adhesives As
Pressure-Sensitive Peel-and-Seal Closures
Hot melt pressure-sensitive adhesives for closure strips that must remain protected by a release liner until the customer is ready to seal the mailer.
Plastic Mailer Manufacturing
Adhesive and application systems designed for consistent placement, clean cutoff, dependable closure, and efficient high-volume production.
Paper Mailer Manufacturing
Technologies selected around paper construction, coatings, recycled content, closure design, production speed, and end-use expectations.
Release-Liner Application
Precision equipment and process support for placing adhesive and release liners accurately and consistently during mailer production.

Why Mailer Manufacturers Contact HAR
Pressure-sensitive closure strips are inconsistent, misaligned, or failing to seal dependably.
Hot melt stringing, cutoff, coat weight, or release-liner placement is affecting high-speed production.
The manufacturer wants to add or improve paper, plastic, or packaging-on-demand mailer capabilities.
A new film, paper, recycled, or more sustainable structure requires adhesive and equipment evaluation.
Existing adhesive and application-equipment suppliers are not working together effectively.
The company wants an experienced partner in pressure-sensitive hot melts, heat-seal coatings, and precision mailer application systems.
