1 Carton Packaging World

Many people mistaked that carton packaging is the combination of the box template structural design and graphic design In fact, the carton packaging is far more than that

In this chapter we will explain by two small examples : the carton packaging is a macrocosm, this industry is promising if you get involved

Trang 4

The client needs the packaging box structure

shown above, the carton box size is 80*45*100(mm)，cardboard

Sample 1《 Carton Packaging World 1.1 The cost difference between two minor difference box templates

with specific cardboard size

Folding carton classification

Trang 13

2.1 The definition of tubes

Tubes《 Folding carton structure analysis

It originally refers to the smallest box lid area amang, such as toothpaste

boxes, such as toothpaste box

Now, it is generally defined from the molding characteristics: it refers to the

carton box that need both the lid and bottom closure panel fixed or sealed

during the molding process

Trang 14

2.1.1 The structure of the tubes

Trang 15

2.1.2 The closure structure of Tubes

Commonly closure structures：

7 Snap lock bottom

8 Automatic lock bottom

Trang 16

2.1.2.1 Friction Tuck

Closure《 Tubes《 Folding carton structure analysis

The sealing structure uses the friction between the tongue, dust flap and the panels to achieve and maintain sealing, the

sealing strength and reliability is poor, suitable for small,

lightweight daily necessities and pharmaceutical packaging

Trang 17

2.1.2.4 Seal end

The locking strength and reliability of the sealend structure is higher, but it is less convenient

Trang 18

2.1.2.6 Push-in closure

Each flap is part of the pattern, after plug-in the flaps composite a beautiful pattern

Trang 19

2.1.2.5 Locking tab

The locking tab structure combined the friction and lock end sealing structure With high sealing strengt and reliability, it is suitable for heavier contents

Trang 20

2.1.2.7 Concave/Convex

The Concave Convex structure with the own strength and stiffness of the cardboard,

deformation of straight or curved creasing line on the box, depressed flaps to achieve sealing

the recessed portion

and the creasing

line of the length

must be 1/2 of the

width

Trang 24

2.1.2.10 Automatic lock bottom

The automatic

lock bottom refers

to the body and

the bottom of the

box can be folded

into a flat plate

shape, and the

bottom of the box

complex and the

cost is higher than

other boxes

Trang 25

2.1.2.10 Automatic lock bottom

From the automatic lock bottom

structure, we can see both the

flap and width angle of the box

are 45 °, it is to avoid overlapp

when folding

Part A is the locking tab which

is located the intersection of 1/2

length and 1/2 width of the box,

it is to enhance the lock strength

The shade area is the glued part, it is folded on the opposite direction The larger size the glued part, the more firmly

The 2 ° slash on Part B is to facilitate waste remove from the slash after carton box cutting

die-The 3mm width in part C is to prevent the carton rupture after multilayer paper overlapped

Widely used tube box templates《 Tubes《 Folding carton structure analysis

The reverse tuck also abbreviated as RTE, it is the most primitive box template

Trang 28

2.1.3.2 Straight tuck

The straight tuck also

abbreviated as STE

Its drawback is that the

two projections, when step

and repeat it wastes paper

material, but it is suitable

used for the window style

box

2.1.4 10 principles of the folding carton structural design

10 principles of the folding carton structure design

Trang 32

2.1.4.1 10 principles 1-2

10 principles《 Tubes《 Folding carton structure analysis

（1）Whether the product has individual packaging

• plain tuck flap：Individual packaging, do not need to consider pollution,

scattered factors

• slit-lock tuck flap：The tuck structure is more conducive to the production and operation compare to the glued structure

（2）One time open or multiple times open during usage

• slit-lock tuck flap:It offers more secure closure design than the one time

open, mainly used on heavier content packaging

• plain tuck flap：It keeps the integrity of the folding carton with multiple

times open

Trang 33

2.1.4.1 10 principles 3~5

（3）Heavy weight products

• tuck and tongue lock：It provide a very secure cover design

（4）Whether consumers expect to be able to see the product before

buying?

• Aperture or window：The product can be see clearly

• Plain tuck flap：The customer could even touch the product

（5）Whether the products need to be leak-proof structure？

• double-glued end seals：The non-independent packaging product coated with glue on two dust flaps and the back cover, which is more effective to prevent leakage

Trang 34

2.1.4.1 10 principles ~6

（6）Which process included in the carton packaging production?

• Each process in carton packaging production can be completed by

equipment or by hand, it should be equipped with a different design on manual, semi-automatic or automatic production

Trang 35

2.1.4.1 10 Principles 7~8

10 Principles《 Tubes《 Folding carton structure analysis

（7）Whether the carton box need to prevent unexpected opening？

• double-glued end seals:The glued operation can prevent the folding

carton with unexpected open, such as toothpaste box

（8）Which loading way the folding carton applied?

• Vertical loading：Commonly loading way, it is easy for mechanized

production; such as grain and powder

• Horizontal loading：The basic design is the same with vertical loading,

only changes the open direction Automation equipment is more complex

• Top loading：Some products require bigger diameter loading This type of folding carton is often designed with KDF( knocked-down-flat) or flat

sheets delivered Dimensionally unstable products (such as clothing) tend

to use the top loading design, as well as toys

（9）How to use the folding carton？

• The folding carton design need to consider how it could be storaged On the dresser or drawers? Medicine cabinet or refrigerator?

• Easy to open, accessible and tear lines and other auxiliary design should considered in the carton box design

（10）How to sale the product？

• Excellent folding carton design is helpful for the sales display

• It need to provide a stable and attractive display way

2.2.1 Molding method

Trays《 Folding carton structure analysis

Each panel of the tray folding carton

need to be connected with certain

structure, the concrete molding method

include:

（1）Fold assembly

（2）Lock connection

Trang 39

2.2.3 Top and Base

a) Top lid：The height of the lid equal to the height of the box so that it almost cover

up all the box body

b) Cap lid：The height of the lid is less than the height of the body, generally only

covering the upper opening portion of the body

c) Buckle lid：The body with matching edge to seam with the lid, the height of the

box equal to the height of the lid and the height of the matching edge of the box

body

a）top lid b）cap lid c)Buckle lid

The lid, body of the box are mutually independent with open structure, the inner

dimension of the lid is slightly larger than the outer size of the tray to ensure that the

lid can be smoothly cover on the body The top and base structure used for shoes,

clothing and assembled goods

2.2.5 Commonly tray structure

Commonly tray structure：

1 Double side wall

2 Foot lock

3 4-spot glued

4 6-spot guled

Trang 43

2.2.5.1 Double side wall

Commonly tray structure《Trays《 Folding carton structure analysis

As the name suggested, the wall

structure of the tray has doubled, it

is easy of production, various parts

folded completely, normally can be

made of top and base box

Since the glued part need to be

folded to form the double side wall,

its maximum value can not exceed

the depth of the box subtracting

the thickness of the paper

Trang 44

2.2.5 2 Foot lock

The foot lock plays both

the foot and lock rule of

the box

The size of the male lock

is smaller than the size of

the female lock in the box

lock structure, the male

lock is drawn to the inside

with 15 ° angle, and the

female lock is 15 ° angle

to the outside The four

fixed flaps folded can not

affect the lock, it is the

relationship between C

and C-2B in the tray

structure

Trang 45

2.2.5.3 Four-spot glued tray

Four-spot glued tray is one of the

most simple and valuable box

template, it also named Beers tray,

mainly for packing shirts, sweaters,

food and toys etc

The biggest characteristics of

Four-spot glued box is the lid and the

bottom of the tray can be completely

the same size to match perfectly,

unlike other trays, the lid must be

bigger than the bottom

Trang 46

2.2.5.4 Six-spot glued tray

The change and design of the

six-spot glued tray is on the basis of

four-spot glued tray.It is widely used

in frozen food, fish, seafood,

vegetables packaging fields

The width of the lid is 2 times bigger

than the width of the bottom

3 The Offset

4 The texture direction

5 The texture direction design of Tubes

6 The texture direction design of Tubes with curved surface

7 The texture direction design of Trays

8 The texture direction design of regular polygon trays

Trang 48

3.1 The bearing characteristics

《 The characteristics of folding carton

As we all know but may not pay special attention to the phenomenon: the bearing force of flat sheet cardboard is small, once creasing and properly folded, it could bear great pressure

Trang 49

3.2 The influence of the two sides of the paper on structure design

No matter ordinary cardboard or corrugated board has two sides, ordinary

cardboard has a surface layer and a bottom layer, corrugated cardboard

has out layer paper and inner layer paper

It influences the molding when folding, which need to be taken into account

in the structure design

（a）Inner fold 90° （b）Outer fold 90° （c）Inner fold （d）Outer fold 1-bottom layer 2-surface layer 3-bottom layer 4-surface layer

Trang 50

There is an example：

Caliper 2mm, Length 40mm.The creasing line is on the middle of the cardboard Then we start to fold

Trang 51

There're two concerns:

1 the length of the cardboard is 40 mm before folding, after folding the inner size isn't 40/2=20mm,it is 19mm because of the caliper

2 The first statement is not entirely accurate,because of the two sides of the paper, when folding on the middle, the internal loss is different with different specifications of the cardboards, it need to

be taken into account
