What are Heat Seal Adhesives?

Heat Seal Adhesives & Coatings or Heat Seal Films are Hot Melts or Liquids that are applied to  paper, film, non-woven or foil substrates and Dried.  The final bond is not formed until the  Heat Seal Adhesive is later – Re-activated.

---

Cattie Adhesives manufactures a Full Line of  Hot Melt Heat Seals,  Heat Seal Films & Tapes,  Water based Heat Seal & Solvent based Heat Seal Coatings for many industrial – Food Packaging,  Flexible Packaging,  Paper Converting  and  Specialty Applications.

---

Our Heat Seal Adhesives & Coatings can be applied by different methods including –  Knife over roll, reverse roll, nip roller, gravure, brush, spray or roller. 

The Heat Sealing process can be performed Both In-line or after initial application.

---

Our Heat Seals can also be Custom formulated for specialty applications to meet requirements for –  viscosity, solids %, non-blocking, clarity & heat sealing temperature.

---

We also have the capability to  Coat our Heat Seals  onto many different substrates including  – felts, films, liners, magnet, papers, plastics, and textiles; for various medical and industrial applications.

---

We can supply our Heat Seal adhesive products in  – Tape and Roll Stock Form.  Click here for more information.

Below are some of our most common types of Heat Seal Adhesives:

---

# 7-8258

7-8258 Acrylic Emulsion heat seal adhesive –  58% Solids,  100cps.  A packaging adhesive polymer that is heat reactive, self-curing acrylic latex with carboxyl functionality.  Strong adhesion to polar substances with excellent water resistance; fast drying and high bond strength for wet laminations; high oil and plasticiser resistance after crosslinking; broad FDA approvals.

General Information:  7-8258 is excellent for wet laminating because it dries rapidly and develops high bond strength quickly. It performs well in high speed laminating operations.  # 7-8258 also forms strong bonds at relatively low heat sealing temperatures – critical for many temperature-sensitive substrates.  It has good specific adhesion to most polar substrates, and it forms tough, permanent bonds. It also has good water resistance.

# HS410

HS410 is an EVA type heat seal film adhesive – Self-wound on a 42# silicon liner that is transferable from the silicon liner.  HS410 has a wide range activation temperature with good adhesion to a variety of substrates including metals, coated films, papers and plastics. It was designed for bonding to difficult substrates in the sanding disc and Tin Tie adhesive markets.
