Bostik provides highperformance laminating adhesives engineered to maintain bond integrity under retort, hotfill, freezer, microwave, and highspeed lamination conditions. These solutions are designed to ensure consistent quality, reduce curing delays, and minimize line failures across demanding structures such as PET/PE, PET/ALU/PE, PET/metPET/PE, BOPP/PE, and OPA/PE.
Common Lamination Problems We Help You Solve
- Delamination After Retort or Pasteurization
High‑performance solvent‑based systems provide strong adhesion on PET/ALU/PE and deliver the heat resistance required for retort / sterilization applications.
- Poor Bond Strength on PET/PE and Other Polyolefin Laminates
Bostik technologies include solvent‑free and solvent‑based adhesives formulated for strong adhesion on polyesters, polyolefins, aluminum foil, and metallized films.
- Foaming During Application
Stable solvent‑free PU formulations demonstrate good processability and controlled rheology to minimize foaming risk under recommended operating conditions.
- Inconsistent Peel Strength or Weak Laminate Interface
Heatseal and laminating adhesives provide controlled peel strength behavior, including systems designed for high resistance to grease, acids, and oils.
- Curing Time Too Long → Production Delay
Certain solvent‑free and solvent‑based systems support shorter curing times, faster slit times, and high running speeds (up to ~300–400 m/min depending on the solution).
High Temperature & Hot Fill Performance
Bostik laminating adhesives maintain bond strength under demanding thermal conditions, offering strong adhesion for PET/ALU/PE retort structures and stability under hot‑fill temperatures. Certain systems tolerate microwave exposure ranges of 104–121 °C and provide freezer‑resistant performance depending on chemistry
High‑Speed Lamination & Production Efficiency
Solvent‑free and solvent‑based technologies support high‑speed lamination up to ~300–400 m/min, with controlled curing and slit times as short as 8–24 hours depending on grade. Stable wettability and adhesion to PET, PE, PP, OPA, foil, metallized films, and paper help reduce defects and improve operational reliability.
Solutions for Demanding Laminate Structures
Bostik adhesives provide strong bonding and resistance required for structures such as PET/ALU/PE in aggressive thermal or chemical environments. PET/PE, OPA/PE, and metallized laminates benefit from reliable adhesion and product resistance. BOPP/PE and BOPP/BOPP snack structures achieve stable performance even at high speeds.
