    8766 Al Foil Adhesive Flexible packaging, Two-Component Polyurethane adhesive,lamination adhesive


    Introduction of 8766


    The 8766 is two-component solvent based polyurethane adhesive, suitable for composite aluminum foil, pretreatment of polyethylene and polypropylene, polyester, polyamide, aluminum film, Sailuofen material.


    According to the amount of film smooth agent (such as in the PE film or EVA film in oleic acid amide erucic acid amide) and film with different thickness the adhesive performance will be different. 8766 in the initial bond strength with high peel strength. Composite processing technology is suitable for plastic / plastic water products.

    4, Coating: 8766 adhesive suit for dry composite device with smooth or concave roller. Suggest many time tests before mass production, to make sure suit network roller.


    5, Coating Amount: it accords to compositing situation between plastic file and aluminum foil, and the final purpose of the film. Coating Amount of adhesive could be managed from 2.0-3.8g/m2 (dry adhesive), adjust coating amount for printed film is required, usually 0.5-1.0g/m2 more than the film unprinted.


    6, Drying: Composite equipment should have good air volume, wind speed, wind pressure and proper temperature, to avoid residual solvent, stripping fault. Set the temperature generally follow the principle of 55 ℃ -65 ℃, 65 ℃ -75℃, 70 ℃ -85 ℃. According to the performance, product processing technology of composite raw materials, adjusting the temperature of oven.


    7, Press Adjustment: properly increasing compositing temperature and line pressure can improve the adhesion and surface finish degree of composited film.


    8, Curing: it could be cut after complete curing within 24hours in 40℃-50℃, and made to bag should be extend curing time. Ordinary products curing at room temperature, curing time need 2-5 days. For packaging purposes suggested boiled 50-55 ℃ for curing 48 hours; for more than 100 ℃ steam use recommended 50-55℃ for curing 72 hours.


    9, Adhesive film properties: completely cured 8766 polyurethane film is transparent, no odor, elasticity and aging resistance.


    10, Adhesion properties test data: In a variety of plastic / plastic exhibit excellent adhesion to composite products in the process of boiling.


    11, Product Certificate: Comply with FDA175.105


    12, Caution:No contact with skin


    13, Others: Film additive (especially slippery agent), are important end use pretreatment and coating packaging items, printing ink, thinner, operating environment, quality of thin film composite products, and will affect the performance of direct or indirect. Before mass production, the actual composite test and examine appropriate composite products are necessary.


    Practice compositing test and film test is necessary before mass production. Detailed Instruction refers to “Adhesive Compositing Technology Instruction”.
