Frequently asked questions
What thickness (mil) are Arplast poly mailers?
All of our poly mailers are a strong 2.5 mil opaque film, the sweet spot for apparel, soft goods and most e-commerce shipping. The same 2.5 mil specification runs across every size in the range.
What sizes of poly mailers do you offer?
Ten stock sizes of opaque poly mailers: 5×7, 6×9, 7.5×10.5, 9×12, 10×13, 12×15.5, 14.5×19, 19×24, 24×24 and 26×32. Smaller sizes suit accessories and single garments; larger sizes handle bedding and bulky textiles. Custom sizes are available on request.
How do I choose the right poly mailer size?
Lay your product flat, measure its largest dimension and pick a mailer slightly larger so the flap folds and closes cleanly. Use 5×7 through 9×12 for flat or single items and 14.5×19 and larger for bulky, compressible goods.
Why choose opaque poly mailers?
The opaque 2.5 mil film conceals contents for privacy and gives packages a clean, professional look, with shipping and return labels standing out against a smooth surface. The opaque construction is consistent across all ten sizes.
Is there a minimum order for poly mailers?
There is no minimum on in-stock poly mailer sizes, so you can order a single case or buy in bulk for high-volume fulfillment. Wholesale and volume pricing lowers your cost per unit as quantity increases. Arplast has manufactured and distributed poly packaging in the US for over 30 years.
Can I get custom-printed or custom-size poly mailers?
Yes. Arplast offers custom sizes and custom printing, so you can add your logo, brand colors and messaging to turn a plain mailer into branded outer packaging.
