Mailer or Cardboard Boxes: Which is suitable for which shipment?
Mailer are suitable for flat, lightweight, and less fragile shipments. Cardboard boxes are better when products need stable protection, padding, or are to be sent as a package.
Whether it's an offer, sample, spare part, catalog, file folder, or goods: the right packaging saves effort, protects the contents, and makes a professional impression on the recipient.

Short Answer
For documents, flat papers, and lightweight items, mailers are practical. For fragile, heavy, or bulky products, cardboard boxes with suitable void fill are usually the better choice.
Why packaging must match the shipment
Packaging that is too large results in unnecessary void fill and can mean higher shipping costs. Packaging that is too small or too weak does not adequately protect the contents. That's why it's worth taking a quick look at weight, shape, fragility, and shipping method.

Consider void fill and packing tape
The right outer packaging is only part of the solution. For boxes, void fill is often also needed so that the contents do not shift. Suitable packing tape ensures that the shipment remains securely sealed.
