About Corrugated Boxes

The more people learn about corrugated boxes, the more they realize that there is nothing "basic" about them. With every box made up of three sheets of paper, the combinations are limitless. But don't worry…..that is what we are here for. We've tried to make this page informative with easy to digest information that will get you up to speed on the basics ofcorrugated cardboard.

CARDBOARD BOX TYPES

While this is not meant to be an exhaustive list, below are some of our most common box types that Aruna can provide. Each box serves a specific purpose depending on the type of product being housed.

Regular Slotted Containers
This is the most common box style. All flaps are the same length from the score to the edge. Ideal for: Shipping small individual items such as cups and mugs, books,apparel, processed food etc. This is the most cost effective design for a given measurement.
Corrugated Trays
Corrugated Trays are basically trays to hold other objects. They are advantageous when product visibility and easy handling are of prime importance. Ideal for: Food and beverage industry products such as bottled water, soft drinks, snack foods, and bulk packaged processed foods.
Half Slotted Containers
Corrugated Trays are basically trays to hold other objects. They are advantageous when product visibility and easy handling are of prime importance. Ideal for: Food and beverage industry products such as bottled water, soft drinks, snack foods, and bulk packaged processed foods.
Die Cut Custom
These are custom corrugated boxes developed to exact specifications depending on your requirements. Aruna can manufacturer custom boxes with FULL color available in all styles and custom sizes. Ideal for: Unique products with special requirements such as cosmetic product boxes, toy product boxes, gift product boxes, display cartons etc.
Full Over Lap
The outer flaps overlap the full width of the box making it especially resistant to rough handling. All flaps are the same depth, and their depth equals the width of the box. Ideal for: Heavy objects that require extra support such as refrigerators, washing machines, engineering goods etc.
Roll End Tuck Top
The outer flaps overlap the full width of the box making it especially resistant to rough handling. All flaps are the same depth, and their depth equals the width of the box. Ideal for: Heavy objects that require extra support such as refrigerators, washing machines, engineering goods etc.
These are simple unglued boxes that need to be folded when assembled. These are great for shipping narrow items. Ideal for: Vitamin Packaging, retail packaging, coffee packaging, tea packaging.
TYPES OF PRINTING METHODS
Printing Method Description Advantages
Flexo Line The most basic type of printing on corrugated. Allows the addition of company or package content info to the surface of the box, at a relatively low cost. Graphics tend to be basic line art and text, utilizing between 1 and 3 colours.
Offset Process Used for higher end graphics utilizing the 4 process colours. It provides a stronger visual impact, and enables photo quality images to be used Because 4 colour print plates are required, the total print plate costs tend to be more expensive than Flexo Line. Minimum run quantities tend to be much higher than Flexo line.
Label Stickers Achieved by gluing printed sheets to the outer surface of the corrugated material. Enables the application of a glossy process colour (photo quality) image, and is a reasonable cost option for low to medium quantity runs. Label size is limited by the maximum sheet size of most commercial presses (28" x 40"). It provides a clean professional appearance that looks comparable to high end packaging like that used with software and electronics. Labels can be applied as a 100% coverage, or as a spot label in conjunction with other Flexo line printing.
CORRUGATED BOARD STRENGTH

Board strength are all the factors that define how strong the box should be. There are a number of questions you must ask yourself before you can accurately access how strong a particular box should be manufactured to be such as:

CORRUGATED BOX FLUTE TYPES

Corrugated Flutes are the S shaped waves/arches of a corrugated box that makes up the board. This is called the boards corrugation. Flutes are essentially the reinforcement that make up the board. They run parallel to the depth of the container and give it its rigidity and crushing/stacking strength. As well as providing stacking strength, flutes also provide insulation that protects products from sudden temperature changes. Generally speaking, larger flutes like A & B profile provide greater strength and cushioning, while smaller flute profiles like D & E provide better printability and foldability.

B flutes have 42-50 flutes per foot and are 1/8" thick. They provide the second highest arch size. 

B flutes provide good stacking strength and crushing resistance. Ideally used for canned goods and displays.

C flutes have 39-43 flutes per foot and are 11/64" thick. They are the medium between A flute and B flute and are very common. 

C flutes provide good cushioning, stacking and printing properties. Ideally used for glass, furniture and dairy.

E flutes have 94 flutes per foot and are 1/16" thick. The board profile is super-thin which in turn reduces box size and saves store space.

E flutes provide the greatest crush resistance and a super printing surface which make it an excellent choice for die-cut custom boxes. 

CARDBOARD WALL CONSTRUCTION

Aruna provides you with the option of choosing between single(3 ply) and double-wall(5 ply) cardboard construction. If needed we can provide higher plies too.

Single Wall is the most common corrugation material - it simply consists of 1 layer of whatever flute type you choose. Under normal circumstances, single wall construction will be sufficient.

Double Wall construction also known as 'heavy duty' corrugation material is used for heavy or large objects. A Double wall consists of 2 layers of flutes, usually 1 layer of B and 1 layer of C. They are around 35% stronger than the regular single wall corrugation type.

Flute Types Flutes/Foot Thickness Advantages
B Flute 42-50 1/8" Good Cushioning, Stacking & Printing
C Flute 39-43 11/64" Good Stacking, Strength & Crushing Resistance
E Flute 94 1/16" Greatest Crush resistance & Printing Surface
BC Flute Double Wall Very Thick Can hold very large & heavy items
