Material Notes:

Eastobond 19412 is a terephthalate-based copolyester. It is identical to our 19411 resin in every aspect, except that the 19412 has been crystallized for drying purposes and ease of handling. Eastobond 19412 may be dried in a desicated drying system at 150 F. It offers excellent organoleptic and gas-barrier properties. Eastobond 19412 has low postextrusion crystallinity and a low softening point, enabling heat-seal bonds to be achieved over a temperature range of 95°C to 205°C.
