Part 1: What is corrugated paperboard?
• Containerboard is classified as• Singlewall (liner, fluted medium, liner)• Doublewall (liner, medium, liner,
medium, liner)• Triplewall (liner, medium, liner,
medium, liner, medium, liner)• Each flute size and combination offers
varying strength, rigidity, and printing surface.• Larger flutes and additional walls add
strength• Smaller flutes make for a better printing
surface• Advance Packaging Offers
• Singlewall: B, C, and E flutes• Doublewall: BC, EC, and EB
Corrugated paperboard, sometimes called containerboard, is created by adhering the fluted medium to liner to create a rigid board that can be scored, cut, folded, and glued to make cartons, trays, partitions, displays, inserts, and a host of other packaging products

Strength Tests• Corrugated is also classified by its
strength• ECT or Edge Crush Test refers to the
stacking strength. That is, how many pounds per square inch can be applied before crushing
• Mullen Test refers to the bursting strength or pounds per square inch applied before bursting
• Mullen is best suited for protecting heavier contents while Edge Crush is lightweight and better suited for stacking. Edge Crush also boasts a higher recycled content
Circular stamps have the following information from Item 222/Rule 41 table and states the box meets those general requirements• Board Grade (Mullen or ECT)• Size limit, outside dimensions (length + width + depth not to
exceed)• Gross weight limit• Construction (single-wall, double-wall, triple-wall, etc.)• Manufacturers name and location
Square stamps simply state the board grade in either an ECT value or Mullen grade along with the manufacturers name and location. Does not meet Item 222/Rule 41 requirements

Part 2: Packaging Styles• Since this is a 101 webinar, we will just be covering the
most common styles of cartons, trays, and folders.• Advance Packaging has expert designers, sales agents,
and customer service representatives who are able to answer your questions on more complicated packaging or display needs
Slotted Containers
RSC - Regular Slotted Container: This box has top and bottom flaps that are the same length (1/2 the width of the box). The outer two flaps meet in the middle when folded
Benefits of this style: economical to produce and can be opened and sealed quickly by hand or with automated equipment
HSC – Half Slotted Container: This style is the same as the RSC, but has only one set of flaps
Benefits of this style: highly economical to produce, easy to load, and can be used with a tray cover
FOL – Full Overlap Slotted Container: Top and bottom flaps are all the same length (the width of the box) and when closed, the flaps cover the entire top and bottom
Benefits of this style: Adds extra protection and cushioning to ends. It is also best for cartons with narrow widths
Slotted containers are the simplest and most common types of boxes. They are generally made from a single blank, and usually do not require any tooling to make
Auto-lock and 1-2-3 Bottom BoxesThese two styles are easy to set up by hand and on some specialty case erectors, but they require tooling.
Auto bottom boxes are easy to open and do not require any tape to seal the bottom. They require half the labor of RSCs to set up
1-2-3 bottom boxes are also easy to set up, and the bottom snaps into place and holds. The bottom is not fully sealed, however, and not recommended for heavy loads
Trays
Telebody/Telecover: These trays are shipped flat and require the user to tape, glue, or staple the flaps before using
Benefits of this style: It is the most economical to produce and generally requires no tooling Roll End Trays: These Trays are also shipped flat, but the ends fold over and lock into
place Benefits of this style: It is economical to produce (but does require tooling), and it does not
require sealing In Fold Tray: This is a pre-glued tray that requires less labor to set up than
telebodies and covers, but it requires tooling to produce Benefits of this style: When used as a cover, the sides will not “flare out” like the out fold tray
Out Fold Tray: Another type of pre-glued tray that also requires tooling. It is more economical to produce and folds flatter than the in fold, but requires product to stay fully open
Trays can be used to hold product, to serve as covers, or to telescope into a bottom and overlapping top
Trays Continued

FoldersFolders are shipped flat, provide an unbroken bottom, and fold or wrap around product. The most common styles are:• OPF – One Panel Folder: Used for
long parts with shallow depths. Flaps for the sides and ends, and extensions of the side flaps meet in the middle
FF5PF – Full Flap Five Panel Folder: Used for long, thin parts, and has a 5th panel to act as a closing flap. Provides excellent end protection
