Shipping is one of the most important parts of any business. A product may look perfect when packed, but during delivery it can face pressure, stacking weight, sudden movement, and accidental drops. If the packaging is not strong enough, the item inside may bend, break, or get scratched. That is why choosing the right mailers is not a small decision — it directly affects customer satisfaction and business reputation.
Different mailers are designed for different purposes. Some prevent bending. Some absorb shock. Some focus on eco-friendly packaging. Understanding these differences helps you make a smart choice instead of guessing.
