What Are Packaging Hot Melt Adhesives?

Packaging hot melts are thermoplastic glues that bond packaging materials quickly and securely. They’re applied in molten form and solidify as they cool, forming durable bonds with minimal mess — no drying time required. Perfect for automated and high-throughput environments.

Benefits of Hot Melt Adhesives in Packaging Applications

Common Hot Melt Adhesive Packaging Applications

Our packaging adhesives are engineered to perform across a wide range of packaging processes. No matter your product type or line speed, we’ve got a solution that sticks.

Case & Carton

A go-to for shipping boxes, food trays, and folding cartons. Our adhesives bond quickly and hold strong — even under pressure or in cold storage.

Paper Converting

Ideal for laminating, folding, and sealing in paper goods production. Our hot melts ensure quick tack and clean application on various paper substrates.

Bookbinding

From spine glue to side glue, these adhesives offer strong bonds and flexibility — perfect for books, manuals, catalogs, and more.

Product Assembly

Used in everything from furniture to electronics, these hot melts provide strong, reliable bonds with good heat resistance and workability.

Product Labeling

For secure, fast label application — even in challenging conditions like moisture, cold temps, or high-speed bottling lines.

Urethanes

These reactive hot melts (often PUR) offer superior durability, flexibility, and resistance to moisture and heat. Ideal for applications that require long-term performance.

Glue Sticks

Perfect for handheld glue gun use in crafts, light assembly, or small packaging jobs — easy to use, quick to bond, and clean to apply.

Glue Dots

A mess-free alternative to liquid glue, glue dots offer instant tack and clean adhesion for promotional packaging, mailers, and light assembly tasks.

Choosing the Right
Packaging Adhesives

Not all hot melts are created equal. Choosing the right formulation depends on your substrates, speed, and end-use conditions.

Here’s what we help you evaluate:

  • Type of material: coated board, recycled content, plastic, etc.
  • Open and set time requirements
  • Temperature resistance (freezer-grade, ambient, etc.)
  • Machine compatibility (nozzle, extrusion, roller, etc.)
