International Fibreboard Case Code: 09 Series

Liners, tubes, pads, build-ups, dividers, partitions and other inner pieces can be made in an infinite variety of ways to separate or cushion products, to strengthen the box or to prevent product movement by filling voids. This may be simple rectangles, or scored, slotted, scored and slotted, or die cut shapes. Many of the common interior forms have been given International Fibreboard Case Code numbers. The carrier classifications provide specifications for some pieces used in the packing of glassware and other fragile articles.

0900 Pads Pads are plain shapes of corrugated or solid fiberboard. They can be used to fill the space between the inner flaps of an RSC, to completely cover the bottom or top of a box, or to separate layers of product. Vertically, they can be used to separate products.

Tubes are scored rectangles, folded and sometimes joined with tape to
form a multisided structure open at both ends. When used as sleeves for individual items such as glassware, adjacent shell provide double protection.

Inner Packing Piece

Scored and a folded inner packing pieces can take many shapes. Included in this group are built-up pads consisting of multiple pieces glued together. Inner packing pieces are used for cushioning, suspension and separation, and to fill voids. The suspension function holds the product away from the walls of the box to lessen the impact of drops or bumps. Completely filling the voids created by irregularly shaped products adds strength to the box.

Inner Packing Forms are usually die cut to position and support irregular products form below, or lock them into position from above. Alternatively, forms can be place on two sides or ends of a product. Some inner packing forms are extensions of the box flaps.
