In Jain dharma, packaged foods are not automatically chalit/allowed.

They are acceptable only if they are fully suitable for Jain observance, meaning:

• No root vegetables or forbidden ingredients
• No eggs, meat, fish, or animal-derived rennet/gelatin
• No alcohol
• No onion, garlic, if following strict Jain food rules
• No fermentation or items considered unsuitable in your vow level
• Prepared and stored in a way that does not violate Jain principles

For many Jains, packaged food is allowed only after checking the ingredients carefully. If there is doubt, it is better to avoid it to preserve ahimsa and purity.

So the simple answer is: sometimes yes, sometimes no — it depends on the ingredients and your level of observance.
