Gatefold Sleeve

折页唱片封套 (Gatefold Sleeve) is a type of record packaging that opens along a center line or spine, much like a book. When closed, it typically takes the form of a standard record sleeve; when opened, the left and right panels form a continuous inner page, providing more space for images and text than a single-panel sleeve. It is most common for 12-inch vinyl records but can also be scaled down for 7-inch records, CDs, or other media.

The typical structure consists of printed cardstock that is folded and glued together, with one or both sides forming pockets to hold the record. Double albums often place the two discs in the left and right pockets, respectively, but a single record can also use a gatefold, leaving the other side for images, lyrics, or inserts; therefore, “gatefold” describes the packaging structure and is not synonymous with “double album.” Tri-folds, quad-folds, and more complex continuous panels are sometimes still broadly classified as part of the gatefold family. Records are generally placed first into a separate inner sleeve, which is then inserted into the outer gatefold sleeve. The inner sleeve reduces direct friction between the record surface and the rough cardboard and can hold lyrics or copyright information. The direction of the opening, spine thickness, pocket corner cuts, and cardstock weight all affect ease of insertion and removal as well as structural support; thicker records or multiple inserts exceeding the design capacity may cause the spine to bulge, the fold lines to crack, or the record surface to be compressed.

The unfolded inner pages can be used for continuous photographs, illustrations, cast and crew lists, and lengthy descriptions. When printing crosses a fold line, images may be affected by creasing, adhesive, and trimming tolerances; the outer spine is typically printed with the artist’s name, title, and catalog number. Laminating, embossing, die-cutting, and special inks are surface and printing techniques that do not alter the gatefold’s basic opening and closing structure.

The gatefold is distinct from slipcases, box sets, and standard double-pocket sleeves. It is a main sleeve that opens and closes on its own, whereas a slipcase is a box that fits over another piece of packaging, and a box set refers to a collection of multiple items released together. A CD Digipak may also open like a gatefold, but if it includes an adhesive plastic tray and uses the corresponding brand-specific structure, it is generally still classified as a Digipak.
