    Hello, I'm pretty new with lamination and I'm trying to learn if I'm doing everything correctly.

    I'm using a desktop laminator with 35 cm rolls, setting manually the temperature, tensions, speed and so on.

    The problem with the laminate is that after a while the laminated products get contaminated and show pink color.

    I do use often pink alcohol to clean surfaces and machinery (can't avoid it) so my guess is that the laminate is getting the alcool aereosol in the room.

    My question is why the alcohol aereosol or room moisture get inside the laminate ? Professional book products I compare with doesn't have the same problem.

    It could be that the temperature is not enough so that not all the glue is melted leaving an inner space so that the air particles get inside between the laminate and the paper ?

    It could be that the paper is not discharged statically so that the particles are lured inside the intersection being the paper and laminate not-conducting and hence acting as a sort of capacitor ?

    Please check the pictures for better reference:
