When dealing with foils at 0.05mm or thinner, we offer 2 options: Light Tight tested foils (denoted as LT in our catalogue) or standard untested foils (denoted as Sizes in our catalogue).
When the foil thickness surpasses 0.05mm, there's no requirement for a light-tight test, as these foils become naturally denser and provide a more effective barrier against light.
Very limited stock available.
