⚖️ Cardboard envelopes vs bubble envelopes - when to choose each of them?

Both types of envelopes serve different functions, so pay attention to the type of content when choosing:

➡️ When should you choose a solid cardboard envelope?

• Content must be perfectly flat: archival documents, boards, posters, graphics.
• Ecology comes first: 100% paper product, easy to recycle.
• Professional appearance: white, smooth front of the envelope adds prestige.
• Flat products: books, catalogs, discs in boxes.

➡️ When would a bubble envelope be better?

• Sensitive goods: electronics, glass or small items needing cushioning.
• Irregular shapes: bubble wrap adapts to the product.
• Lower packaging cost: traditional bubble envelopes are usually cheaper.
• No priority for ecology: foil hinders recycling.

Companies often combine both solutions, depending on the goods and shipping requirements.
