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

The choice between a solid cardboard envelope and a bubble envelope depends on the type of product and priorities:

➡️ When is it worth choosing a solid cardboard envelope?

• Contents cannot bend: important documents, graphics, posters or catalogs that need to arrive in an undamaged state.
• You focus on ecology: no foil, 100% paper - recycling is not a problem.
• Elegance and professional appearance matter: white cardboard makes the shipment make a great first impression.
• Flat products: books, discs, brochures in boxes - all protected without additional fillers.

➡️ When will a bubble envelope be better?

• Sensitivity to shocks: delicate electronics, glass parts, ceramics requiring damping.
• Irregular shapes: bubble wrap more easily adapts to the contents.
• Lower cost: with mass shipment of cheap items, bubble may be more economical.
• Less important ecology: more difficult recycling due to the combination of paper and foil.

Many sellers and companies use both solutions, adapting the packaging to the type and needs of the shipment.
