Done by Earth group, Mohamed bin AbdulAziz Almana Independent secondary school for boys Food packaging is packaging for food. A package provides protection, tampering resistance, and special physical, chemical, or biological needs. The sodium benzoate used in refrigerators plastic cans to increase the duration of food preservation thus increase food shelf life

1. Food packaging

2. Outline
• Activity 1: (investigating food packaging)
• Activitie2(Analyzing Food Packaging Materials)
• Activity3(evaluating the impact of food packaging on the
environment)
• Activity4(researching food packaging materials)
• Activity5(designing a protective package)
• Activity6(comparing the insulating poperties of packaging
materials)
• Product Idea(Add sodium neutrons on plastic bottles)

3. Introduction
OFood packaging is the food
enclose in the package may
require protection from ,
among other things , shock
, vibration , compression ,
temperature , etc .

ANALYSIS OF FOOD PACKAGING
MATERIALS
Objective
Knowing the weight of the food and the net and the extent of damage to the
environment
And appropriate amounts

7. Procedure
 We have the weight of the food and drink
without casing
 Then the weight of the cover alone
 Then we know that the law Net

10. Activity4(Throwing eggs)
 Objective
 Comparison between natural materials and industrial materials
 Which is better with liquids, whichever is best with the material is liquid

11. Procedure
We bring in 2 eggs and 2 of the bags and put the bags in one of the natural
material with the eggs and put the egg sac with other industrial material and
close the bag and each bag we throw out that broken eggs and record every
time you throw away

14. Activity5(Throwing tomatoes)
Objective
Know the difference between power tomatoes coated and non-coated
taking into account the weight

15.  We bring in 2 of the tomatoes we encapsulates 1
and the survival of the afterlife without packaging
 We weight of packaging
 We then weight of tomatoes and use this law to
know the extent of damage to the net and
packaging on the environment
 Then we threw tomatoes from a height of 50 then
100sm then 150 ..... etc. to the crash tomatoes and
record results

17. Conclusion
 The tomatoes coated withstand more than non-coated

18. Activity6(Temperature materials
with changing times)
 Objective
 Knowledge of the extent of temperature change with
the change of time and whichever is best to keep the
temperature has to be an insulator or without
insulator

19. Procedure
 Bring 4 cups empty
 And 2 thermometer
 We work from a hole in the 2 cups
 Put hot water in cups that do not have holes and put the tin on
2 of cups, one of them by the hole and the other does not and
put plaster and a thermometer and we begin recording
temperatures with the passage of time either cups hereafter we
put hot water and paste cups and put the thermometer and we
begin to register temperatures

21. CONCLUSION
The materials that have been packaged heat transmitted them less quickly than non-coated

22. We are a group mba_earth 8 We participants
in the contest AL-Bairaq and scientific Haya
contest affiliated with the University of Qatar
and this year's competition for food packaging

23. Final Project:
Smart Plastic cans
for leftovers

24.  Introduction and Rationale:
 We have noticed that the food begins to decay after the period we
wanted to increase the duration cooled validity
The project has a great benefit to the Qatari society, it reduces the
money in consumer consumption Purchase of food
What attracted us to the project that the materials simple and useful
and available
The project has no harm to the environment also benefited from
training with the team AL-Bairaq
 Aim of the work (objectives)
 Our goal is to find a way to increase food validity after being left in
plastic cans in the fridge

25. Hypothesis: ( (الفرضية
 Assume that the materials needed are available and
cheap and not harmful to the environment

26. Methods and Materials
 Sodium benzoate (so we did not find it using the
lemon because it contains sodium benzoate)
 Plastic Boxes

27. Photos


28. Results:
 The sodium benzoate used in refrigerators plastic cans to increase the
duration of food preservation thus increase food shelf life

30. Recommendations:
 We would like to recommend that the research on the
project will continue to develop and improve

31. Conclusions
The sodium benzoate increases food preservation thus
we can use it in the manufacture of plastic cans
