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

Food packaging

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)

Introduction

OFood packaging is the food

enclose in the package may

require protection from ,

among other things , shock

, vibration , compression ,

temperature , etc .

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

Objective

Know the difference between power tomatoes coated and non-coated taking into account the weight

Activity5(Throwing tomatoes)

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

• Material to be tested by group :

Conclusion The tomatoes coated withstand more than non-coated

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

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

CONCLUSION

The materials that have been packaged heat transmitted them less quickly than non-

coated

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

Final Project:Smart Plastic cans

for leftovers

Introduction and Rationale:

We have noticed that the food begins to decay after the period we wanted to increase the duration cooled validityThe project has a great benefit to the Qatari society, it reduces the money in consumer consumption Purchase of foodWhat attracted us to the project that the materials simple and useful and availableThe 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

Hypothesis: (الفرضية)

Assume that the materials needed are available and cheap and not harmful to the environment

Methods and Materials

Sodium benzoate (so we did not find it using the lemon because it contains sodium benzoate)

Plastic Boxes

Photos

Results:

The sodium benzoate used in refrigerators plastic cans to increase the duration of food preservation thus increase food shelf life

Recommendations:

We would like to recommend that the research on the project will continue to develop and improve

Conclusions

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