When taken out of the freezer, the temperature of the sausages is likely less than 0 degrees C.
When water vapour in the surrounding air comes into contact with the surface of the wrapping, heat energy is transferred from the water vapour on the wrapper, causing the water vapour to decrease in temperature. This happens until the temperature of the water vapour reaches 0 degrees C which is the freezing point of water. The white solid formed is the frozen water vapour

When the pack of brown sausage was taken out of the freezer, the warm water vapour in the surrounding air came into contact with the colder surface of the clear plastic and caused the water vapour to lost heat and condense into water droplets. The water droplets continues to lose heat to the cold sausages and it turned into ice when the temperature reaches 0 degree Celsius and therefore, there is white solid seen on the surface of the plastic wrapping.
