Cotton paper enclosure
An enclosure with four flaps designed to store photographs and photographic films. Sometimes it is also used to store glass plate negatives, although envelopes are usually preferred for this purpose. This classic construction is made from the most expensive paper Beskid Plus has on offer, i.e. cotton paper. This material does not contain an alkaline agent - calcium carbonate - owing to which it is perfectly neutral and can come into contact with chemically "agressive" photographic materials.
In larger formats, the enclosure is made from a slightly thicker and sturdier variety of cotton paper, with grammage of 120 g/m2.
