According to the Bureau of Indian Standards (IS: 9845, 2016R), what is the maximum permissible limit of global migration from food contact materials for packaging applications?
Show Hint
Remember the dual limits for global migration:
$10\text{ mg/dm}^2$ of packaging surface area, or $60\text{ mg/kg}$ of foodstuff.
$10\text{ mg/dm}^2$ of packaging surface area, or $60\text{ mg/kg}$ of foodstuff.

- 10 mg/dm\(^2\)
- 60 mg/dm\(^2\)
- 75 mg/dm\(^2\)
- 42 mg/dm\(^2\)

The Correct Option is A
Solution and Explanation
Step 1: Understanding the Concept:
Global migration refers to the total transfer of non-volatile chemical substances from a plastic packaging material into food or food simulants under specific time and temperature conditions.
Limiting global migration ensures that the packaging material does not alter the food's composition or transfer harmful constituents.
Step 2: Detailed Explanation:
The Bureau of Indian Standards (BIS) prescribes the standard test methods and limits for migration in IS: 9845.
According to this standard, the global migration limit for plastic materials intended to come into contact with foodstuffs is strictly regulated.
The limit is defined as:
- Not more than $60\text{ mg/kg}$ of foodstuff (expressed in terms of concentration in food), or
- Not more than 10 mg/dm\(^2\) of the surface area of the packaging material.
Since the options are expressed in units of $\text{mg/dm}^2$, the correct limit is $10\text{ mg/dm}^2$.
Therefore, option 1 is the correct answer.
Step 3: Final Answer:
The maximum permissible limit of global migration is 10 mg/dm\(^2\).
