Abstract
Provided is a polyester composite film, comprising a first thermoplastic polyether ester elastomer (TPEE) film and a second TPEE film. The melting point of a second TPEE resin of the second TPEE film is higher than that of a first TPEE resin of the first TPEE film, and the absolute difference in enthalpy of fusion between the first and second TPEE films is 5 J/g to 15 J/g. By adopting the first and second TPEE films having specific absolute difference of the enthalpy of fusion and controlling the melting points of the first and second TPEE resins, the polyester composite film can be well attached onto the fabric by hot pressing to obtain sufficient peel strength, and thereby the attached fabric can have excellent waterproof performance. Besides, a hot melt adhesive laminate comprising the polyester composite film also exhibits the above beneficial effects when attached to the fabric.
