• Types of labeling
• Types of printing machines
• Labeling machines
• General requirements
• Information
• Some symbols on label
• Advantages & disadvantages
• conclusions

3. OPENING REMARKS
Labelling means attachment of a label on an object and label means a
small piece of paper, fabric, plastic or similar material attached on object
and gives information about it.
Objectives:-
• Identifies the product through its patented color & design.
• Describe about the product that who made it, when is it made, what
are the ingredients ,how to be used ,what is the quantity?
• promote the product through attractive graphics
• Legal stipulation- MRP ,expiry date, contra indication for pharms
products

5. 1.PRESSURE SENSITIVE LABELS
. Pressure Sensitive Labels (also called PSL or self adhesive label or
Stickers) are applied with light pressure without applying the heat. PSLs often
have release liners which protect the adhesive and assist label handling.
Two types
1.Permanent adhesive type
2.Removable adhesive type

6. Flexo and Gravure inks are formulated from the following components:
Typical Flexo – Gravure ink formulation

7. 2.HEAT SENSITIVE LABELS
Two types
INSTANTANEOUS TYPE-
heat and pressure both are applied together to the label to fix
it directly on the container or product. Used in application of end seal of food
packets etc.
DELAY ACTION TYPE-
IN this heat turns the product into a pressure sensitive
item. No direct heat is provided. Used on glass bottles, rigid or semi rigid
plastic containers etc.

10. 5.CUT AND STACK LABELS
Cut and Stack Labels are printed on large sheet or roll fed printing
presses. After printing, stacks of label sheets are either die cut into their
desired shapes or, more typically, cut into their individual rectangular
shapes and stacked (hence the name). The application process most
commonly involves overlapping the label and gluing the label to itself
(lap).

11. TYPES OF PRINTING MACHINES
1.FLEXOGRAPHY
is a form of printing process which utilizes a flexible relief plate. It is
essentially a modern version of letterpress which can be used for printing on
almost any type of substrate, including plastic, metallic films, cellophane, and
paper.

12. 2.LITHOGRAPHY

13. 3.SILKSCREEN

14. 4.HOT FOIL PRINTING

15. LABELING MACHINES
1.WET-GLUE LABEL MACHINE
Functions of wet-glue label machine
1. feed labels one at a time from a magazine.
2. coat the label with adhesive.
3. feed the glue label on to the article to be labeled in correct position.
4. ensure that the articles are held in correct position to be labeled.
5. apply pressure to smooth the label on to the article and press it into
good contact.
6. remove the article when it has been labeled.

16. 2.PRESSURE SENSITIVE LABELING MACHINE

17. 3. HEAT SENSITIVE LABELING MACHINE
• There are two type of heat sensitive labeling machines and the delayed
action type is suitable for machine operation.
• Due the tacky nature of adhesive, after the removal of heat source allows
the designer to separate the heat source from the pressure application to
the label.
• Thus the pressure plates are complex then the heat plates. And varies
from flat to round or irregular shape.

18. GENERAL REQUIREMENTS
• Required information
• Language
• Shall not carry any false and misleading information
• Label shall not separate form packed food material.
• Clear, prominent, indelible and readily legible contents
• In case of wrapped food products, wrapper shall contain necessary
information.

19. INFORMATION
Name of product
Ingredients
Nutritional information
Declaration regards veg or non-veg food
Declaration regards additives
Name and complete address of manufacturer

20. INFORMATION
• Net quantity
• Code/batch number
• Date of manufacture or packaging
• Expiry date
• Country of origin for imported food
• Instruction to use

21. Foods that don’t require every component of the label include:
• small food packets such as chewing gum
• foods for catering
• alcoholic beverages.
Foods that don’t require any label at all include:
• unpackaged food
• food made and packaged where it is sold, or food packaged in front
of you
• ready-to-eat food delivered to order (eg, pizza)
• whole or cut fresh fruit and vegetables in transparent packages
• food sold at a fundraising event
• food in an inner package not designed for sale without the outer
package.

22. SYMBOLS ON FOOD PRODUCTS

23. ADVANTAGES
• Provides information related to food product.
• Gives batter look to the packed food product.
• It helps in regulate the quantity of the fat, sugar, cholesterol in our diet.
Disadvantages
• Increases the cost of food product
• Due to false and misleading information, people may go under
dangerous zone

24. CONCLUSIONS
• labeling gives the information related to the product which helps
to costumer to select the right product according to their choice.
• But sometime false labeling may create hazard full conditions.
So if such type of cases are happened then we should lodge a
complain against that company in the consumer court.
