SchemppBox Type 9: Folders, envelopes
Folders and envelopes are mainly used as inner packaging within boxes.
Legal folders are often used to separate individual, thin file bundles. Their advantage over file envelopes is that the contents are secured against slipping or falling out by the three flaps.
File covers are usually folded or grooved only once in the middle. They are used to hold single sheets or very thin bundles of documents. Envelopes for individual documents are made of archival paper and can even be used as inner packaging within legal folders, for example, to secure certain sheets particularly well.
Folders for maps and prints usually have larger formats and are used to store large-format documents such as maps, technical drawings, posters or prints.
Fourflap folders are often used to pack glass plates.
Envelopes made of archival paper, photo archival paper, Melinex/polyester or glassine are mainly used in the field of photo archiving, but are sometimes also used to secure a single sheet, photos or fragments within a file.
Drawstring folders are used to tie up files and keep them securely together.
Protective covers are used to protect book covers from damage to the outside.
Fragile individual items such as prints, documents or glass plates can be safely stored and transported in covers and folders with passe-partout.
The folders, covers and sleeves can be produced in almost any format. An upper size for the production from one piece results from the dimensions of the blank sheet.
