Box Basics

History of Corrugated BoxesThe 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 mae this page informative with easy to digest information

that will get you up to speed on the basics of corrugated cardboard.

Cardboard Box Types

Regular Slotted Containers

$orrugated Trays are basically trays to hold other ob%ects. They are advantageous when product

visibility and easy handling are of prime importance. deal for# food and beverage industry products

such as bottled water, soft drins, snac foods, and bul pacaged processed foods.

Half Slotted Containers

&alf 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. deal for# large and

heavy ob%ects such as refrigerators and washing machines.

custom sizes. deal for# uniue products with special reuirements such as cosmetic product boxes, toy

product boxes, gift product boxes.

Full Over Lap

flaps are the same depth, and their depth euals the width of the box. deal for# heavy ob%ects that reuire

extra support such as refrigerators and washing machines.

Types of Printing Methods

Printing Method

Description

Advantages

(lexo *ine

The most basic type of printing on corrugated.

!llows the addition of company or pacage content info to the surface of the box, at a relatively low

cost. +raphics tend to be basic line art and text, utilizing between and - colours.

(lexo rocess

)sed for higher end graphics utilizing the / process colours. t provides a stronger visual impact, and

enables photo uality images to be used.

Because / colour print plates are reuired, the total print plate costs tend to be more expensive than

(lexo *ine. 0inimum run uantities tend to be much higher than (lexo line.

(lood $oated

!llows the use of a solid 112 coverage of colour. 0ost commonly used with 3 displays and

pacaging for retail applications.

(lood coats can be applied with stoc print plates, so die costs are not an expense for the client.

*abel *aminate

!chieved by gluing printed sheets to the outer surface of the corrugated material. 4nables the

application of a glossy process colour 5photo uality6 image, and is a reasonable cost option for low to

medium uantity runs. *abel size is limited by the maximum sheet size of most commercial presses 578"

x /1"6.

t provides a clean professional appearance that loos comparable to high end pacaging similar to that

used with software and electronics. *abels can be applied as a 112 coverage, or as a spot label in

con%unction with other (lexo line printing.

9creen rint

!nother way of applying graphic intensive images directly to the outer surface of the corrugated

pacage.

This process is most commonly used for 3 displays and retail pacaging applications, and can be

more cost effective is short run uantities. 9ize limitations are larger than label laminate, and colour

combinations greater than / are possible.

*itho *aminaterovides a similar finished product as label laminate, but reuires much higher minimum runs 5typically

1:71;6.

The printed surface is actually part of the pacaging material, as opposed to label laminate which is

added manually.

reprint

roviding a similar finished product to (lexo process, this process involves the client purchasing pre

printed rolls of paper that are used in manufacturing linerboard.

t reuires very high volume runs, and a significant upfront investment by the client, but can be a cost

effective way to apply impactful graphics at those uantities. 0ost commonly used in the food and

beverage industry, lie beer cases and mandarin orange boxes.

Corrugated Board Strength

Board strength are all the factors that define how strong the box should be. There are a number of

uestions you must as yourself before you can accurately asses how strong a particular box should be

manufactured to be such as#

The nature of the products being pacaged

The total weight of the box

The size of the box

&ow the cardboard box will be staced, 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.

B flutes provide good stacing strength and crushing resistance. deally used for canned goods and

displays.

$ flutes have -A:/- flutes per foot and are ouble wall consists of 7 layers of flutes, usually layer of B and layer of $. They are

around -?2 stronger than the regular single wall corrugation type. Boxmaster offers double wall

cardboard boxes from //4$T to 4$T.

Edge Crush TestThe 4dge $rush Test is simply a method used to determine the "stacing" 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 4$T will determine the probable compression strength of the container made from the

board.
