Auto Bag Rolls
Similar to perforated rolls, each bag has a front slit to make product loading simple and avoid the need for removing individual bags. These bags are often used with automatic bag-filling machinery.

Center Special Slotted Container (CSSC)
Custom-made containers that provide a double layer of cushioning as well as a sturdy base for contents.

Corrugated
A corrugated box is made from two or more sheets of linerboard and one or more fluted sheets of corrugated.

Cubed Foam
Also called "diced" foam. Polyether foam sheets, which have been perforated into 1" cubes. They are left attached so you have the ability to "pluck" cubes to achieve a desired space and custom look.

Density
A foam used to define the relative compactness of the cell structure of foam or any material. Higher density, rated in pounds per square inch, is for higher weight items and lower density is for lighter weight items.

Depth
Measurement from top to bottom.

Die Cut
A precision cutout matches the item to be encased accurately. A pre-cut, steel rule template is typically used as the "die". Foam, corrugated and plastics are common materials for die cutting.

Dust Flaps
On the side of an RETT lid that tuck down into the box when closing.

Five Panel Folder
The first and fifth length panels of the box overlap to provide extra strength.

Flip-Top Bag
A side-welded bag with an extra lip that tucks in for closing.

Fragility
Used to define the relative strength of an item to be packaged. A low fragility factor means strong and durable while a high fragility factor means fragile and delicate.

Full Overlap Flaps
Corrugated containers used when additional strength is needed. Commonly used when carton closure is done with staples.

Gauge
The thickness of a product, such as pallet wrap in polyethylene bags, usually measured in millimeters.

Gusset
A special pleat, on the side or bottom of a polybag, when it is fully extended. Extra dimension provides additional space.

Half Slotted Container
These containers have one set of flaps and require a lid. Covers can be full telescoping that completely fit over the other or trays, which partially telescope to a lesser depth over the body of the box.

Header Bags
Polyethylene bags with printed paperboard graphics for high visibility merchandising.

I.D.
Inside dimensions.

Length
The larger of the two dimensions of the open or flap opening space, when measuring a box. Top opening space to bottom when measuring a bag.

O.D.
Outside dimensions.

One Piece Folder
Die cut fold up box. Extremely easy to use and among the least expensive. Great for books.

Pallet
A wood or other composite material used to facilitate handling by forklifts and other mechanical devices. See Skid.

Pallet Wrap
A stretch film commonly used to protect and secure loads of packaged goods. Pallet wrap is sometimes confused with Shrinkwrap, which is a heat sealable film. See Shrinkwrap.

Perforated Rolls
A continuous roll of bottom-sealed bags attached to each other with perforated seals for easy dispensing.

Poly
Shortened form of Polyfoam, Polyethylene or Polyester foam.

Polyethylene
Flexible higher density foam material ideally suited for items with higher concentrations of weight. It is also extremely reusable and washable.

Polyethylene Bags (Polybags)
Commonly used for packaging a wide variety of products. Sizes listed are two dimensional for lay-flat polybags – width and length. Width is measured along the bag's opening side. Length is measured perpendicular to the width measurement up to, but not including, the bottom seal. A gusset adds a third dimension for extra space.

Regular Slotted Container (RSC)
RSC is the most widely used corrugated box because it is the easiest to manufacture and has maximum versatility. All flaps are the same length.

Roll End Tuck Top (RETT)
A container well suited for items requiring retail merchandising in addition to regular commercial shipping.

Shrinkwrap
A packaging film requiring heat that contracts the film to tightly fit a product and protect against moisture, separation and damage. Shrinkwrap is often confused with Pallet wrap, which is a stretch film. See Pallet Wrap.

Single-face Corrugated
Consists of one layer of corrugated medium bonded to a single layer of linerboard. Provides flexible cushioning, sold in rolls, and commonly used to wrap heavy products.

Single-wall Corrugated
Consists of a second facing glued to the other side of the fluted corrugated. More than 90% of all boxes used in the United States are made from Single-wall board.

Skid
Usually made of wood or plastics. Used to unitize and elevate the product from the ground surface. Also provides space for forklift handling.

Static Control Packaging
Materials, specially treated, to render them non-conductive to the negative effects of static electricity. Excellent for PC boards and other electrical or magnetic products requiring protection from static buildup and discharge.

Stretch Film Pallet Wrap
A high-cling stretch film excellent for hand or machine wrap applications.

Stretch Tape
Small roll of stretch film (pallet wrap) used for bundling, holding or securing. Replaces conventional methods of tying, taping or banding.

Triple-wall Corrugated
A third layer of fluted corrugated linerboard offering exceptional strength for packaging very large or heavy products. Often replaces plywood used in crating and is more cost-effective.

Wicketed Bag
A side-welded bag with two holes punched in lip for attachment. This setup allows easy individual bag display at removal.

Width
The same or smaller of the two dimensions of the open, or flap opening space for boxes. For bags, width defines the opening space.
