Bubble mailers, or padded mailers, are lightweight envelopes with a cushioned inside to keep items safe during shipping.
Why are they called bubble mailers?
Bubble mailers get their name from the bubble wrap lining inside the mailer. This bubble wrap consists of small air-filled bubbles that provide cushioning and protection for the items being shipped. The outer layer of the mailer can be made from various materials like polyethylene (poly), kraft paper, or other materials, but it's the inner bubble wrap that gives these mailers their distinctive name.
3 Types of Bubble Mailers
1. Padded paper mailers
Paper mailers are usually made entirely of paper and are great for lighter items. Within this category, there are two main types: padded paper mailers and honeycomb paper mailers.
Padded paper mailers are made with an outer layer of kraft paper and an inner layer that acts as padding, typically made from shredded or layered paper. The inner padding absorbs shocks and prevents damage to the contents.
Where to get them:
- Ecoenclose Padded Mailers: Upcycled paper cushioning, plastic-free and naturally biodegradable
- Noissue's Stock Protective Kraft Mailers: Recycled paper, padded with recycled-paper pulp, and curb-side recyclable.
Honeycomb paper mailers are also made from kraft paper but with a honeycomb-patterned inner layer for cushioning. The honeycomb design creates small pockets of air between the paper layers, which provides protection during shipping.
Where to get them:
Cons of paper-padded mailers:
- Not waterproof. Paper is more prone to damage if exposed to water or high humidity.
- Paper can tear or puncture more easily than plastic under rough handling.
Best for:
- Books and magazines, if slight moisture won't damage the product (e.g., already shrink-wrapped or protected).
- Pre-packaged food. Dry goods like snacks, teas, or coffee beans that are sealed.
- Handmade accessories. Non-metal items like woven bracelets or keychains that won’t be ruined by minor exposure to moisture.
2. Biodegradable plastic bubble mailers
Biodegradable plastic bubble mailers have the cushion protection of traditional bubble mailers while being environmentally friendly. These mailers are made from materials that break down more quickly (usually with biodegradable polymers ((like PLA, PBAT)) and naturally in the environment compared to standard plastic. The inside layer consists of air-filled bubbles to protect items from shocks and impacts during transit.
Biodegradable bubble mailers are also water-resistant. They can protect products inside from moisture and humidity. The material is generally more durable than paper as it offers better resistance to tearing and punctures.
Cons of biodegradable plastic bubble mailers:
-
Not compostable.
Best for:
- Books and documents.
- Non-fragile electronics: Small gadgets and accessories like phone cases and chargers.
- Small/light clothes and accessories
- Handmade items like artisanal goods like candles, soaps, or jewelry.
- Beauty products. Lightweight items like makeup brushes, packaged skincare, or hair accessories that can withstand transit.

3. Kraft bubble mailers or kraft padded mailers
Kraft bubble mailers are shipping envelopes with a kraft paper exterior and an inner layer of plastic bubble wrap for cushioning. This is perhaps the cheapest option (depending on where you buy it from) on this list. However, they fall short in one critical area: sustainability. Most recycling facilities can’t separate the plastic from the paper, meaning they often end up in landfills.
Where to get them:
- Amazon
- In bulk through suppliers
Cons of kraft bubble mailers
- Not eco-friendly and sustainable due to the plastic inner layer.
- Less durable in wet conditions compared to plastic mailers.
Best for:
- Books and documents.
- Small, lightweight items like jewelry or accessories.
- General shipping needs where cost is a priority.
