Learn About Corrugated

 

Ninety percent (90%) of all goods shipped to market are packaged in corrugated! There are many standard styles and an unending array of custom designed packaging products.

Corrugated is the ultimate in flexible
packaging material.

Boxes are manufactured in many basic styles, from which you may choose the best to package your product. From there, your packaging can be customized even further. Interior packaging can be added to fit your container to hold and protect your products during movement during shipment.

In order to better inform our customers about their packaging needs, we have included this glossary of corrugated terms.

RSC style box
Box Structure
Architects have known for thousands of years that an arch with the proper curve is the strongest way to span a given space. The inventors of corrugated fiberboard applied this same principle to paper when they put arches in the corrugated medium. These arches are known as flutes and when anchored to the linerboard with a starch-based adhesive, they resist bending and pressure from all directions.
Custom Packaging Solution
Custom Packaging Solution
A container system that includes both the outside container and frequently inner packaging of different materials to protect the product. If well designed, it is both highly functional and economical.
Corrugated
Corrugated, or Combined, Fiberboard
Has two main components: the linerboard and the medium. Both are made of a special kind of heavy paper called containerboard. Linerboard is the flat facing that adheres to the medium. The medium is the wavy, fluted paper in between the liners. |TOP of PAGE|
Single Face Corrugated
Single Face
One medium is glued to one flat sheet of linerboard. |TOP of PAGE|
Single Wall Corrugated Board
Single Wall or Double-Faced
The medium is between two sheets of linerboard. Also known as Double Face. |TOP of PAGE|
Double Wall Corrugated Board
Double Wall
Threesheets of linerboard with two mediums in between. |TOP of PAGE|
Triple Wall Corrugated Board

Flute Direction
Flutes
The wavy paper, or medium, adhered with a starch composition and heat to the liner(s). |TOP of PAGE|
Flute Sizes
Flute Sizes
Flutes come in several standard shapes or flute profiles (A, B, C, E, F, etc.). A-flute was the first to be developed and is the largest common flute profile. B-flute was next and is much smaller. C-flute followed and is between A and B in size. E-flute is smaller than B and F-flute is smaller yet.
Generally the larger flute profiles give greater vertical strength and cushioning. The smaller flutes help enhance graphic capabilities while providing greater structural integrity. Different flute profiles can be combined in one piece of combined board. For instance, a doublewall board can use a B-C flute combination.
By experimenting with flute profiles, our designers can vary compression strength, cushioning strength and thickness. |TOP of PAGE|
scoring
SCORING
a machine-made depression in the box blank to aid in folding the box into its shape.
SCORING ALLOWANCES
The thickness of the corrugated sheet must be taken into account when figuring out where to place scores. A score made on the surface of corrugated sheet will penetrate to the middle of the sheet when the sheet is folded. This means half the thickness of the corrugated sheet hangs to the inside of the box, effectively reducing the inside dimensions by that amount. Scoring Allowances are critical to proper box measuring. |TOP of PAGE|
Partitions
PARTITION
made from a variety of media, slotted strips are fitted together to form cells, into which product can be placed and kept apart from product in other cells.

Chipboard
CHIPBOARD

Plain Chipboard - A low-cost, non-bending chipboard made of recycled materials. Not suitable for printing, often used for divider pads and setup boxes.

WVLC - White Vat Lined Chip, or "white vat"- Plain chip made with a layer of white paper on one side. Used for setup boxes where a white interior is desired. Generally not suitable for printing.

DKL - Double Kraft Lined Bending Chip, or "double kraft", has a layer of recycled kraft fibers on both surfaces for additional strength and resistance to cracking when creased. Double kraft is generally used for folding cartons in commercial/industrial applications. It has a printable surface but is not well-suited for multi-color print jobs. |TOP of PAGE|
