Typical Features:

High initial bonding strength. Outstanding transparency of the laminated film

Uneasy to create the residue with printing ink and films, make safer package.

Suitable to operate in middle and high-speed dry laminating machine.

The laminated films made by AG1050A/B is especially suitable for food and medicine package which have a strict stipulation of the sanitation safety, and suitable for the products which require the lower solvent-residue.

Comply with US FDA 21CFR175.105.

Performance Comparison

Example: Films for laminating (OPP30ink / CPP30); printed area: 60%; operate by Machine made by Fuji; Laminating speed: 120m/min; Curing 12hours at 45°C; base on liquid  chromatography Shimadzu.

	Toluene	Ethyl Ester	Ethanol/Propanol	Other residue
Ester based PU adhesive	1.9mg/ m2	2.2mg/ m2	1.1mg/ m2	0.7mg/ m2
AG1050A/AG1050B	1.0mg/ m2	0.2mg/ m2	1.4mg/ m2	0.4mg/ m2
Alcohol based Adhesive have much lower residue than Ester based Adhesive
