Black 10.5x16 in Large Poly Bubble Mailers #5 - 100 Pack USA Made

Our review of these Black 10.5x16 in Poly Bubble Mailers #5 finds them well suited for small businesses and home sellers who need a durable, lightweight option for shipping flat or lightly padded items. The clearest reason to buy is protection: the air-lined bubble cushioning and reinforced seams deliver reliable shock resistance during transit while remaining water-resistant and light enough to keep postage costs down. These 100 pack mailers are made in the USA and include self-seal tape, which simplifies packing for moderate-volume shippers.

Key Features

• Size: The 10.5x16 in outer dimensions with a usable interior of about 10.5x15 in fit documents, framed photos, and soft goods without folding.
• Bubble cushioning: Air-lined bubble interior provides shock absorption to protect items from pressure and impacts during handling.
• Self-seal tape: Built-in adhesive strip closes the mailer quickly and keeps contents secure without tape dispensers or extra glue.
• Water resistance: Poly construction resists moisture better than paper envelopes, helping protect contents in damp conditions.
• Durability: Strong seams and a smooth non-corrosive inner surface make packing easier and reduce punctures or tearing in transit.
• Made in USA: Domestic manufacturing supports consistent quality control for bulk purchases.

Who It's For

These mailers are ideal for small businesses, Etsy sellers, print shops, and online retailers shipping flat goods like photos, thin books, clothing, or soft accessories. The pack of 100 and light weight make them practical for sellers who ship regularly and want a balance between protection and postage economy.

Shippers who need rigid protection for fragile breakables or high-value electronics should look for padded boxes or foam-lined solutions instead. Also, if you require a resealable closure, these single-use self-seal envelopes are less suitable than resealable poly bags.
