Which mailer is right for your products?
Choose Bubble Mailers When…
- You ship fragile or semi-fragile products (electronics, cosmetics, candles, glassware)
- You want built-in protection without adding void fill or extra dunnage
- Your brand positioning leans premium or boutique — the padded feel reinforces quality
- You ship small-to-medium items where a box is overkill but a flat mailer is too risky
Choose Poly Mailers When…
- You ship apparel, soft goods, textiles, or any non-fragile product
- Postage cost matters — poly mailers weigh the least and keep shipping rates low
- You need waterproof, tamper-evident shipping bags that survive rain and rough handling
- You want maximum branding surface area with a glossy or matte full-bleed print
