Poly Mailers 10x13 Biodegradable Shipping Bags - Designer Waterproof

In this review we look at the Poly Mailers 10x13 pack from Impack, a set of designer biodegradable shipping bags intended for clothing and small accessories. The bottom line: these mailers are best for small online retailers who want a stylish, waterproof option that reduces environmental impact without adding much bulk. They combine a sturdy self-seal adhesive with a printed exterior that makes a positive first impression, and the biodegradable construction is the single biggest reason to choose them over standard plastic mailers.

Key Features

• Premium Shipping Bags For Clothes: Thick construction and a strong self-seal adhesive protect garments from tears and spills during transit.
• Waterproof Mailing Envelopes: The poly material keeps products dry and reduces damage from moisture on delivery days.
• Eco-Friendly Mailing Bags: Designed to break down faster than standard plastic mailers, they are a better choice for retailers wanting to reduce waste.
• Stylish Poly Mailers: Designer prints like Wildflower provide a branded unboxing moment that complements small business aesthetics.
• Small Canadian Business: Designed and quality-tested in Canada, available in small pack quantities suitable for independent sellers.
• Lightweight Yet Durable: The mailers add minimal shipping weight while still offering reinforced protection for clothing and accessories.

Who It's For

These mailers are ideal for small e-commerce shops and independent sellers shipping clothing, scarves, small accessories, or other soft goods who want a polished presentation and a more sustainable shipping option. The 10x13 size fits many folded shirts, leggings, and lightweight items while keeping postage costs low.

They are less suitable for sellers who need padded protection for fragile items or for merchants who require much larger sizes; if you ship bulky or breakable goods, padded or box-based solutions are a better choice. Also, customers needing completely home-compostable certification should verify local disposal conditions since biodegradability timelines can vary.

Pros & Cons

Pros

• Durable, waterproof material with reliable self-seal adhesive keeps contents protected from moisture and handling.
• Biodegradable formulation reduces long-term environmental impact compared with standard plastic mailers.

Cons

• The 10x13 size is versatile but can be too small for larger garments or multi-item orders.
