발송인 means sender or shipper. It is a more formal, business-like word, so you often see it in shipping, delivery, and postal contexts.

• 발송인 = sender / shipper
• 보내는 사람 = the person who sends it

Both can refer to the same person, but 발송인 sounds much more official and document-like.

완충재 means packing material, cushioning material, or protective filler used to prevent damage during shipping.

Examples include:

• bubble wrap
• foam
• air pillows
• packing paper

The word is made from:

• 완충 = cushioning / buffering
• 재 = material

So it literally means something like cushioning material.

를 is the object marker. It marks 완충재 as the thing being put in.

The verb is 넣다, which means to put in or to insert.

So:

• 완충재를 넣다 = to put in packing material

Here, the sender failed to put in the packing material, so 완충재 is the direct object of 넣다.

Both are possible, but they are slightly different in tone.

• 안 넣는 = a more conversational negative
• 넣지 않는 = a more formal or written-style negative

Since the whole sentence sounds formal and report-like, 넣지 않는 fits well.

Also, this form is modifying 바람에, so it works like:

• 넣지 않는 바람에 = because they did not put it in / as a result of not putting it in

So the sentence is using a more polished written style.

-는 바람에 means something like:

• because of
• as a result of
• due to

But it has an important nuance: it is usually used when the result is negative, unfortunate, or something the speaker regrets or blames.

So:

• 발송인이 완충재를 넣지 않는 바람에 물건이 파손됐습니다 = The item was damaged because the sender did not include cushioning material.

This sounds stronger than a neutral because. It suggests that the sender’s failure caused an undesirable outcome.

This is a very common question.

1. -는 바람에

Used when the result is usually bad, regrettable, or inconvenient.

• 비가 오는 바람에 못 갔어요. = I couldn’t go because it rained.
  • This sounds like the rain caused a problem.

2. -아서/어서

A general because/so, often neutral.

• 비가 와서 못 갔어요. = I couldn’t go because it rained.

3. -기 때문에

A more explicit and often more formal because.

• 비가 왔기 때문에 못 갔어요. = I couldn’t go because it rained.

In your sentence, -는 바람에 is used because the result is negative and there is a sense of blame or complaint.

Because each belongs to a different part of the sentence.

발송인이

This marks 발송인 as the subject of the first clause:

• 발송인이 완충재를 넣지 않는 = the sender not putting in cushioning material

물건이

This marks 물건 as the subject of the second clause:

• 물건이 파손됐습니다 = the item was damaged

So the full sentence has:

• cause: the sender didn’t put in cushioning material
• result: the item was damaged

Korean often has multiple subject markers when a sentence contains multiple clauses.

파손되다 means to be damaged or to get damaged. It is a formal word often used in shipping, logistics, insurance, and customer service.

So:

• 물건이 파손됐습니다 = The item was damaged.

This is more formal than everyday verbs like:

• 깨지다 = to break, shatter
• 망가지다 = to get broken, damaged, messed up

For a package, product, or shipped item, 파손되다 is very natural.

Yes.

• 파손되었습니다 = full form
• 파손됐습니다 = contracted form

This contraction happens a lot in Korean:

• 되다 → 돼
• 되었습니다 → 됐습니다

So:

• 파손되었습니다
• 파손됐습니다

mean the same thing. The shorter form is still polite and formal enough for many real-world situations.

Not exactly.

파손되다

• formal
• broad meaning: damaged, broken, impaired
• common in business or shipping contexts

깨지다

• more literal physical breaking
• often used for things like glass, dishes, screens

For example:

• 유리가 깨졌어요. = The glass broke.
• 상품이 파손됐어요. = The product was damaged.

If you are talking about a shipped item in a formal complaint or notice, 파손되다 is usually the better choice.

Yes, definitely.

Because of -는 바람에, the sentence does more than simply describe cause and effect. It suggests that the sender’s failure led to a bad outcome.

So the tone can feel like:

• because the sender failed to include cushioning material, the item was damaged
• the sender not including cushioning material caused the damage

It is not an extremely emotional accusation, but it does carry a sense of criticism or responsibility.

Yes. Here are some alternatives.

More neutral

• 발송인이 완충재를 넣지 않아서 물건이 파손됐습니다. = The item was damaged because the sender didn’t put in cushioning material.

More conversational

• 보내는 사람이 완충재를 안 넣어서 물건이 망가졌어요. = The item got damaged because the sender didn’t put in packing material.

More formal/business-like

• 발송인이 완충재를 넣지 않아 물건이 파손되었습니다. = The item was damaged because the sender did not include cushioning material.

Your original sentence is formal and has a slightly stronger sense of unfortunate consequence.

A very useful chunk here is:

-지 않는 바람에

It is a pattern you can reuse.

Examples:

• 늦잠을 자는 바람에 지각했어요. = I overslept, so I was late.
• 비가 오는 바람에 행사가 취소됐어요. = The event was canceled because it rained.
• 서류를 준비하지 않는 바람에 신청을 못 했어요. = I couldn’t apply because I failed to prepare the documents.

If you learn this pattern as a set, it becomes much easier to recognize and use.
