PES Hot Melt Adhesive Film with Backing Paper: A Safer Industrial Bonding Solution

In the field of industrial manufacturing, the performance and safety of adhesives directly impact product quality and the sustainability of production processes. As global environmental and occupational health and safety (EHS) requirements become increasingly stringent, PES hot melt adhesive film with backing paper is rapidly replacing traditional solvent-based adhesives, emerging as the preferred material for high-end manufacturing sectors such as automotive, renewable energy, and textiles. As a national high-tech enterprise specializing in hot melt adhesive materials, Nantong Feiang Composite Materials Co., Ltd. provides safer and more efficient bonding solutions through its independently developed PES hot melt adhesive film technology.
1. Chemical Safety: From VOC Reduction to Occupational Health Protection
The core safety risks of solvent-based adhesives stem from organic solvents (e.g., toluene, acetone) in their formulations. These substances not only release high concentrations of volatile organic compounds (VOCs) during production but also pose fire and explosion hazards during storage and application. Statistics indicate that approximately 23% of factory fires in global manufacturing are linked to improper handling of solvent-based adhesives.
In contrast, Nantong Feiang’s PES hot melt adhesive film employs a 100% solid composition design. Bonding is achieved through a hot melt process that eliminates solvents entirely, delivering three key safety advantages:
Zero VOC Emissions: Prevents respiratory irritation for operators and complies with ISO 14064 environmental management system certification.
Elimination of Combustion Risks: Precise temperature control (160–180°C) ensures heating remains far below the material’s flash point.
Reduced Process Risks: Solid adhesive film allows direct lamination without investments in ventilation or explosion-proof equipment.
2. Material Innovation: Breakthroughs in Backing System Safety
The liquid nature of solvent-based adhesives often leads to uneven adhesive layers and substrate penetration. PES hot melt adhesive film, however, achieves groundbreaking innovation through its backing paper carrier:
Pre-coated Technology: Adhesive layers are uniformly applied to release paper with ±2μm precision, ensuring bonding consistency.
Instant Activation: Melting, wetting, and curing occur within 3–5 seconds of heating, avoiding defects like shrinkage or air bubbles caused by solvent evaporation.
Dual Protection from Backing Paper: The release paper provides physical isolation and blocks moisture and contaminants during storage, maintaining chemical stability.
In solar panel encapsulation, this technology has passed TÜV Rheinland certification: PES-backed adhesive film retains 98.5% peel strength after 85°C/85%RH damp-heat aging tests, significantly outperforming solvent-based adhesives (76.2%).
3. Full Lifecycle Safety: Closed-Loop Design from Production to Recycling
Nantong Feiang’s PES hot melt adhesive film demonstrates deeper safety value in sustainability:
Cleaner Production: Closed-loop hot melt extrusion reduces energy consumption by 40% and wastewater discharge by 92% compared to solvent-based adhesive lines.
Non-Toxic Waste: Residual film can be reshaped via hot pressing, avoiding hazardous waste disposal challenges.
Recyclable End Products: Compatible with eco-friendly substrates like TPU and PET, supporting EU REACH-compliant material sorting and recycling.
In automotive interiors, this technology helped a German automaker pass ELV (End-of-Life Vehicle) compliance audits, achieving 100% recyclability for seat fabrics.
4. Industry Applications: Redefining Safety Standards
As one of China’s few companies with core PES film expertise, Nantong Feiang has established new safety benchmarks across industries:
Renewable Energy: Double-layer PES film for solar panel shingling encapsulation passes IEC 61215 PID resistance tests, ensuring 25-year outdoor durability.
Medical Protection: Bio-compatible adhesive film for protective garment seams meets ISO 10993 cytotoxicity certification.
Wearable Technology: Ultra-thin (15μm) conductive adhesive film enables safe bonding of flexible circuits, enduring over 100,000 bending cycles.
In the era of Industry 4.0 and carbon neutrality, material safety has become a key indicator of corporate competitiveness. Nantong Feiang Composite Materials Co., Ltd. continues to expand the safety boundaries of PES hot melt adhesive film—from product performance to process innovation, worker health, and full-industry sustainability. This safety-driven innovation creates long-term value for partners and leads the green transformation of the adhesive materials industry.
