Cardboard Box Types

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.

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

Half slotted containers are similar to regular slotted containers except that they have only one set of flaps. The opposite side of the box is open, which allows it to slide over an item. Ideal for: large and heavy objects such as refrigerators and washing machines.

Die Cut Custom

These are custom corrugated boxes developed to exact specifications depending on customer requirements. Boxmaster can manufacture 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.

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 and washing machines.

Roll End Tuck Top

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.

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 asses how strong a particular box should be manufactured to be such as:

  • The nature of the products being packaged
  • The total weight of the box
  • The size of the box
  • How the cardboard box will be stacked, stored, and transported.

Boxmaster provides you with two different levels of customization options when selecting box strength. The first is the flute type and the second is using the edge crush test.

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.

Corrugated Box Construction

Boxmaster provides you with the option of choosing between single and double-wall cardboard construction.

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 as they are offered from 23ECT to 44ECT.

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. Boxmaster offers double wall cardboard boxes from 44ECT to 61 ECT.

Edge Crush Test

The Edge Crush Test is simply a method used to determine the "stacking" or "crushing" of a piece of corrugated board. The test is conducted to determine the force that will crush a containerboard standing on an edge. The ECT will determine the probable compression strength of the container made from the board.
