Frequently Asked Questions
Are poly mailers breathable enough for summer clothing?
No — standard poly mailers are waterproof plastic and don’t allow airflow. For summer clothing, wrap items in breathable tissue or include silica desiccant/odor-absorbing strips to prevent trapped moisture and odors.
How do I choose the right size poly mailer?
Match the mailer to the folded dimensions of the garment with a little extra room for padding. Use 12 x 15.5 inches for single tees or swimwear, 19 x 24 inches for dresses or multi-item orders, and small sizes like 7.5 x 10.5 inches for accessories.
Can I reuse these self-seal poly mailers?
The peel-and-seal adhesive is generally single-use. Lightly used mailers can be resealed with tape, but for brand professionalism and security it's usually better to use fresh mailers for customer orders.
