Chúng ta tái chế bao bì này.

Chúng ta means we in the inclusive sense: the speaker includes the listener.

So this sentence uses chúng ta because it means something like you and I / all of us recycle this packaging.

By contrast, chúng tôi means we but not including the listener.

• Chúng ta tái chế bao bì này. = We (including you) recycle this packaging.
• Chúng tôi tái chế bao bì này. = We (but not you) recycle this packaging.

This is a very important distinction in Vietnamese.

It functions as one verb, meaning to recycle, even though it is written with a space.

Vietnamese spelling often separates syllables, so many words that are really a single vocabulary item appear as two written parts.

Here:

• tái = again / re-
• chế = make, process, manufacture

Together, tái chế = recycle

The same thing happens with bao bì, which is also a single lexical unit in meaning, even though it is written as two syllables.

Bao bì usually means packaging, wrapping, or packaging material.

It is broader than just one specific object like:

• hộp = box
• chai = bottle
• túi = bag
• lon = can

So bao bì is a general word for the packaging around a product.

Depending on context, it may refer to:

• the packaging as material
• the wrapper
• the outer package
• packaging in a general sense

So if you mean a specific kind of item, another noun might be more precise. But bao bì is good for packaging in general.

In Vietnamese, demonstratives like this and that usually come after the noun, not before it.

So:

• bao bì này = this packaging
• bao bì đó = that packaging

This is normal Vietnamese word order.

English:

• this packaging

Vietnamese:

• packaging this

That feels backwards to an English speaker at first, but it is the standard pattern.

Because classifiers are not required in every noun phrase.

Vietnamese classifiers are especially common when:

• counting things
• being very specific about individual objects
• using certain noun types

But bao bì often behaves more like a general/material/collective noun meaning packaging, so a classifier is not necessary here.

That is why bao bì này sounds natural.

If you were talking about a very specific concrete object, classifiers are often more likely. For example:

• cái hộp này = this box
• chai này or cái chai này = this bottle

But with bao bì, omitting a classifier is very normal.

Vietnamese nouns are often number-neutral unless something makes the number clear.

So bao bì này does not strongly mark singular or plural by itself in the way English does.

In practice, it is often understood as:

• this packaging
• this piece of packaging
• sometimes a context-dependent these packaging materials

If you want to make plurality clearer, Vietnamese can add words like:

• những
• các
• a number
• a classifier phrase

For example:

• những bao bì này = these packages / these packaging items

But in many real sentences, context is enough.

Vietnamese verbs do not change form for tense the way English verbs do.

So tái chế stays tái chế whether the action is present, past, or future. Time is usually understood from:

• context
• time words
• aspect/tense markers

In the basic sentence Chúng ta tái chế bao bì này, it can sound like:

• a simple present statement
• a general fact
• an instruction-like statement, depending on context

If you want to be more explicit, you can add markers:

• Chúng ta đang tái chế bao bì này. = We are recycling this packaging.
• Chúng ta đã tái chế bao bì này. = We recycled / have recycled this packaging.
• Chúng ta sẽ tái chế bao bì này. = We will recycle this packaging.

So the original sentence is natural even without a tense word.

Yes. This sentence follows the common Vietnamese order:

Subject + Verb + Object

• Chúng ta = subject
• tái chế = verb
• bao bì này = object

So:

• Chúng ta / tái chế / bao bì này
• We / recycle / this packaging

That part is actually quite similar to English.

One major difference is inside the object phrase: này comes after the noun.

Sometimes yes, but it changes the feel.

Vietnamese often omits subjects when they are obvious from context. However, in a neutral full sentence, keeping chúng ta is natural and clear.

Compare:

• Chúng ta tái chế bao bì này. = We recycle this packaging.
• Tái chế bao bì này. = Recycle this packaging. / Recycling this packaging. / Let’s recycle this packaging, depending on context

So if you remove chúng ta, the sentence may sound more like:

• an instruction
• a slogan
• a note
• an incomplete statement waiting for context

A very rough guide is:

Chúng ta tái chế bao bì này
≈ choong ta tai che bao bee nai

But that is only approximate. The tones matter a lot:

• chúng — ngã tone
• ta — level tone
• tái — rising sắc tone
• chế — rising sắc tone
• bao — level tone
• bì — falling huyền tone
• này — falling huyền tone

A few useful notes:

• ch in chúng is like English ch
• nh in này is a Vietnamese consonant sound, not exactly like English ny, though that is a decent beginner approximation
• the tones are essential for sounding natural and being understood

If you are learning pronunciation, it is best to listen to native audio rather than rely only on English-style approximations.
