Questions buyers ask
Is it waterproof?
The film and the heat-sealed seams are water-resistant, so contents stay dry in rain and through courier handling. The self-seal strip is not submersible.
How thick is it, and will it tear?
60 µm LDPE film, white outside with a black inner layer. It resists punctures and tearing with soft goods; for sharp or heavy items use a padded mailer or box.
Can I stick a shipping label on it, or write on it?
Yes. The matte white surface takes standard thermal labels and permanent markers.
Can the bag be resealed?
No. The adhesive strip is permanent and tamper-evident. For returns, your customer uses a new bag.
Can I print my logo on these?
Yes. Custom-printed mailers start from 50,000 pcs. Request a custom quote →
