Poly Bubble Mailers 8.5 x 13.5 in - Waterproof Cushioned Envelopes

Our review of these Poly Bubble Mailers finds them best suited for small businesses, crafters, and anyone shipping non-fragile but value-sensitive items who need lightweight, waterproof protection. The single biggest reason to buy is the combination of a waterproof polypropylene exterior and 3/16in bubble cushioning that protects against moisture and light impact while keeping postage costs low because the mailers add virtually no weight. The pack of 50 offers consistent quality for routine orders, and the peel-and-seal closure provides tamper-evident security on most parcels.

Key Features

• Waterproof exterior: Polypropylene construction keeps contents dry in wet conditions and during rainy transit.
• Bubble cushioning: 3/16in bubble lining provides a protective layer that reduces scuffs and light impact to shipped items.
• Lightweight: The mailers add almost no weight to packages, helping keep shipping costs down for volume shipments.
• Self-adhering seal: Peel-and-seal closure makes packing fast and creates visible tamper evidence after sealing.
• Durable material: Poly material is puncture and tear resistant for everyday mailing of soft goods and apparel.
• Value pack: Fifty envelopes in one set is convenient for businesses handling regular orders or seasonal spikes.

Who It's For

These mailers are a practical choice for online sellers of clothing, small textiles, books, and other items that do not require heavy-duty cushioning. Small businesses and hobbyists who need a balance of protection, waterproofing, and low mailing weight will get the most out of this product.

Shippers who need rigid protection for fragile items, or who require exact advertised internal dimensions for fitted products, should look for specialty boxes or heavier padded mailers. Also, buyers seeking oversized or custom printed mailers will want an alternative supplier.
