How to Choose the Best Envelope Mailers
When to Use Different Mailer Types
For standard letters and documents, basic paper envelopes or thin poly mailers suffice. If you're shipping books, small electronics, or anything prone to bending, a rigid cardboard mailer or a padded envelope is recommended. Apparel, textiles, and soft goods are well-protected by durable and water-resistant poly mailers. For multiple items or thicker products, expanding mailers provide the necessary capacity. Always choose a mailer that offers adequate protection for the specific item being shipped.
Frequently Asked Questions
What is the difference between a rigid mailer and a padded mailer?
Rigid mailers are typically made of stiff cardboard and are designed to prevent bending or damage to flat items like photos or important documents. Padded mailers have cushioning inside, such as bubble wrap, to protect more fragile contents from impact during shipping.
Are poly mailers waterproof?
Poly mailers are generally water-resistant, offering good protection against moisture and light rain. However, they are not completely waterproof and may not withstand prolonged submersion or heavy downpours.
How do I choose the right size mailer?
Measure the dimensions of the item you plan to ship, including any packaging it's already in. Then, select a mailer that is slightly larger than your item to allow for easy insertion and a snug fit, preventing movement.
What does 'gusseted' mean for an envelope mailer?
A gusseted mailer has expandable sides or a bottom, allowing it to hold thicker items or a larger volume of contents than a standard flat envelope. This extra depth is useful for shipping multiple items or bulky products.
Are there eco-friendly mailer options available?
Yes, many manufacturers offer mailers made from recycled content or those that are biodegradable and compostable. These options help reduce environmental impact compared to traditional plastic or virgin paper mailers.
