⚖️ Cardboard envelopes vs bubble envelopes - when to choose each one?
The choice between a solid cardboard envelope and a bubble envelope depends on the nature of the item being sent and priorities:
➡️ When should you choose a solid cardboard envelope?
- No bending allowed: crucial when sending documents, graphics, photos.
- Ecology and aesthetics: 100% paper packaging is easier to recycle and looks professional.
- The product has a regular, flat shape: books, discs, brochures.
- Prestige: white cardboard enhances the impression of attention to detail.
➡️ When will a bubble envelope be better?
- Sensitive to shocks contents: delicate electronics, glass or ceramic parts.
- Irregular shapes: bubble wrap conforms to the contour of the item.
- Lower cost for mass shipping: usually cheaper when bought in bulk.
