Để riêng bao bì nhé.

Here để means leave, keep, or set aside. It does not mean in order to, which is another very common use of để in Vietnamese.

So in Để riêng bao bì nhé, để is the main verb: it tells someone what to do with the packaging.

Riêng here means separately or apart.

So để riêng together gives the idea of keep separate, leave aside, or set apart.

In other contexts, riêng can also mean things like personal, private, or particular to someone/something, but in this sentence it clearly means separate.

Bao bì means packaging: things like the bag, wrapper, box, outer covering, or packing materials.

It is a fairly general term. Depending on context, it could mean:

• the outer wrapping
• the bag or box
• the packaging material as a whole

So it is broader than just one specific item.

Vietnamese often leaves out the subject when it is obvious from context, especially in:

• instructions
• requests
• reminders
• everyday conversation

So Để riêng bao bì nhé is like an understood imperative: (You) keep the packaging separate, okay?

This is very normal in Vietnamese and does not sound incomplete.

Nhé is a very common sentence-final particle that softens the sentence and makes it sound friendlier.

Here it adds a feeling like:

• okay?
• please
• alright?
• just do that for me, okay?

Without nhé, the sentence would sound more direct or blunt:

• Để riêng bao bì.

With nhé, it sounds more natural and polite in everyday speech:

• Để riêng bao bì nhé.

Vietnamese word order does not always match English expectations. In this sentence, riêng comes right after the verb to describe how the packaging should be left: separately.

So you can think of để riêng as a small unit meaning:

• leave separately
• set aside

Then bao bì is the thing affected.

For an English speaker, it may feel unusual at first, but this kind of compact spoken order is normal in Vietnamese.

Yes. Để bao bì riêng nhé is also understandable and natural.

The two versions are very close:

• Để riêng bao bì nhé
• Để bao bì riêng nhé

The first can feel a little more like set the packaging aside as a spoken instruction. The second may feel a bit more transparent to learners because the object bao bì appears earlier.

In real conversation, both can work, depending on speaking style and context.

Vietnamese nouns usually do not show singular/plural by themselves.

So bao bì could mean:

• the packaging
• the package materials
• the wrapper(s)/box/bag, depending on context

You understand the number from the situation, not from the noun form itself.

It sounds natural, casual, and polite enough for everyday use.

You might hear it in situations like:

• shopping
• takeout or delivery
• shipping
• recycling or sorting items
• asking someone not to throw away the packaging

It is not highly formal, but it is not rude either. Nhé keeps it friendly.

If you wanted to sound more explicitly polite, you could add words like giúp:

• Để riêng bao bì giúp mình nhé.

A few helpful notes:

• để: đ sounds like an English d, and ể has a dipping/rising tone
• riêng: one syllable, roughly something like ree-ung compressed together
• bao: like bao, with a level tone
• bì: bee with a falling tone
• nhé: starts with nh, which sounds like the ny in canyon, and has a rising tone

A rough learner-friendly approximation might be: deh? ree-ung bao bee nyeh

That approximation is imperfect, but it can help as a starting point. The tones matter a lot in Vietnamese, so it is best to hear a native recording if possible.
