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

Both types have their advantages, but they work best in different situations. Here is a brief comparison:

➡️ When should you choose a solid cardboard envelope?

• Contents cannot be bent or crushed: documents, diplomas, photos or graphics requiring rigid form.
• You care about ecology: 100% paper envelopes, without plastic elements; easy to recycle.
• Professional appearance is important: the cardboard envelope looks solid and aesthetic, which impresses the recipient.
• Product has a regular, flat shape: books, catalogs, discs in a box or documents - you can pack everything without the need for additional fillers.

➡️ When will a bubble envelope be better?

• Content is sensitive to shocks: delicate electronics, glass or ceramic parts requiring damping.
• You are sending small, irregular items: bubble lining adjusts to the shape of the product.
• The lowest packaging cost matters: bubble envelopes are often cheaper and widely available.
• Ecology takes a back seat: they are more difficult to recycle due to the combination of paper and foil.

In practice, many companies use both solutions. The choice depends on the nature of the goods sent and the expectations of the recipient.
