means you have a good seal on the lid. Our ice coolers have this problem on occasion. Basic physics. Cool the air, density goes up pulls a slight vacuum. Doesn't need to be much before it takes some effort to open the lid.
And our portable 12V compressor cooler/freezer for camping does the same thing.
