Export food packaging factories face strict food safety inspection thresholds, and LF 2077 paired with LF 2188 solvent-free adhesive holds complete international and domestic compliance certifications. Fully cured adhesive complies with FDA §175.105, German BfR XXVIII, EU plastic directive 2002/72/EC & 2004/19/EC, and Chinese GB 9685-2016, passing all specific migration limit tests for food contact materials.
Beyond reliable safety performance, it features wide substrate compatibility and stable high-temperature resistance for boiling and retort products. Zero VOC solvent-free formula avoids solvent residue detection failures during customs clearance, greatly reducing export return risks. The balanced viscosity system adapts to automatic dosing equipment, supporting continuous mass production with low defective rate.
Standard weight mixing ratio 100:80 is adjustable between 60–80 parts hardener for different composite layers. Dry coating weight can be flexibly adjusted from 1.2 to 3.2 g/m² based on printed or unprinted films. Mixed glue viscosity rises rapidly after mixing at 40°C, so operators must control feeding volume reasonably to avoid waste caused by gelation.
Storage and transport are convenient: both components are packed in 20kg drums, classified as non-dangerous goods for easy shipment. Unopened storage life reaches 9 months under -30°C~30°C. Hardener contains polyisocyanate, so protective gear and exhaust hood are required during operation. All export packaging manufacturers can choose LF2077/LF2188 to simplify certification procedures and stabilize product quality.
