Composite Mailer Bag
A composite bag is built from more than one film layer, so it resists tearing and puncture far better than a single-layer mailer. It is the pack for orders that are heavy, awkwardly shaped, or valuable enough that a split bag is an expensive problem.

How It Compares With The Alternatives
Compared With Express mailer
The express mailer is lighter and cheaper for soft clothing. Composite is for when damage is actually happening.
Compared With Bubble bag
A bubble bag cushions against impact. A composite bag resists tearing. If both matter, use a bubble bag inside a carton.
