3M Scotchpak™
MA250M
Metal Adhesion Packaging Film
Laminate of a polyester (PET) base film with an ethylene acrylic acid
copolymer heat-sealable layer (EAA). The 3M proprietary lamination process
does not use solvents or adhesives, minimizing potential for product
interactions. This translucent film provides a strong heat-seal to a variety of
clean metal surfaces, metal vapor coatings and other substrates.
