PO/EAA Hot-Melt Adhesive Film
Versatile Bonding for Polar & Non‑Polar Substrates

Bond aluminum, steel, plastic, wood, and fiber. Engineered for excellent chemical resistance and low-temperature flexibility.

PO/EAA copolymer hot-melt adhesive film is an advanced bonding layer designed specifically for "hard-to-bond" materials. It delivers exceptional polyolefin to metal bonding, seamlessly adhering to PP/PE, metals, glass, and fibers. Featuring outstanding acid resistance and tolerance to alkalis and oils, it maintains a low-temperature flexible profile down to -40°C. Available in 0.05-0.25mm thicknesses (110-150°C melting point). We support custom widths and specialized release liners to meet your industrial needs.

Engineered for Extreme Performance

Our PO/EAA adhesive film is formulated to bridge the gap between incompatible materials, offering a reliable, solvent-free bonding solution.

Universal "Super Glue" Layer

Excellent polar/non-polar adhesion. Bonds inherently incompatible surfaces like polypropylene (PP) directly to aluminum or steel without primers.

Chemical Resistance

Highly durable against harsh environments. Exhibits superior acid resistance, and withstands prolonged exposure to alkalis, industrial oils, and solvents.

Low-Temperature Flexible

Maintains structural integrity and flexibility in freezing conditions. Will not crack, shatter, or lose bond strength even at -40°C.

Optimal Flow & Wetting

When activated by heat, the film melts to provide excellent surface wetting, filling micro-gaps in porous or uneven materials like wood and textiles.

Food Contact Grade Available

100% solvent-free and odorless. We offer specialized formulations that meet FDA and EU standards for indirect food contact packaging.

Eco-Friendly & Efficient

A perfect replacement for traditional solvent-based liquid adhesives. Speeds up production lines (instant bond upon cooling) with zero VOC emissions.

Frequently Asked Questions

Technical insights on PO/EAA adhesive film from our engineering team.

What is the difference between PO/EAA adhesive film and standard EVA or TPU films?
While EVA is cost-effective and TPU offers high elasticity, PO/EAA is specifically engineered for superior adhesion to non-polar plastics (like PP and PE) and metals (aluminum, steel). Standard EVA and TPU struggle to bond with untreated polyolefins. Furthermore, PO/EAA offers vastly superior chemical resistance (especially acid resistance) compared to both EVA and TPU.
Can it be used in outdoor or long-term high-humidity environments? Is it hydrolysis resistant?
Yes. Because its base polymer is a polyolefin copolymer, it has inherently low water absorption. It exhibits excellent hydrolysis resistance, making it highly suitable for outdoor applications, architectural panels (like aluminum composite panels), and long-term damp environments without degrading the bond strength.
Does bonding PP/PE require flame or corona surface treatment first?
No. One of the primary advantages of our PO/EAA hot-melt adhesive film is that it achieves structural-level peel strength on untreated PP and PE surfaces. You can skip the costly and time-consuming flame, corona, or plasma treatments, significantly streamlining your manufacturing process.
What standards do the food contact grade PO/EAA films meet?
Our specialized food-grade formulations comply with FDA 21 CFR 175.105 (Adhesives) and relevant EU regulations for indirect food contact. They are 100% solvent-free, odorless, and safe for laminating packaging films used in the food and beverage industry.
Do you provide slitting or rewinding services?
Yes, as a direct manufacturer, we offer comprehensive converting services. We can slit the master rolls into custom widths ranging from 10mm up to 1500mm, and rewind them to your specified roll lengths or outer diameters to perfectly fit your lamination equipment.
