I bought other brands’ glue and it doesn’t work well on the material EVA and Fabric lamination.

I think you need to clear the surface of materials first.
(1) What kind of product you are using? solvent-based or water-based?
(2) Yellow glue / Graft / EVA emulsion / water base acrylic?
(3) I guess you are the lamination or bag factory. If you use contact glue, contact glue usually doesn't have good performance to laminate EVA. Suggest to use grafted glue (BWA-316CH) which is better.
If you are facing difficult EVA materials, you need to know the EVA material is already treated with primer or not.
