## Description

4x8 100% Biodegradable Bubble Mailers,25 Count Kraft Black #000 Compostable Padded Packaging Wrap Envelopes Pouches Eco Friendly Self Seal Bags

## Features

- 100% Biodegradable: our bubble cushioning wrap is made of PBAT and modified corn starch. The envelope is made of kraft. These poly bubble mailers are certified by BPI and OK compost, and meet the standards of ASTM 6400 and EN13432. They are non-toxic , BPA-free and generate less CO2 than traditional plastic.
- Improve Your Corporate Image: your customers will be surprised and relieved to open a bubble mailer made of plant-based eco materials. It will speak volumes about your sense of social responsibility and the high quality of your brand, and help you build a lasting impression with your customers.
- Each bubble envelope contains a four-season self-sealing adhesive strip. The strong stickiness prevents your items from being tampered with during transportation, even in extreme hot or cold weather. Please note: store these compostable padded shipping envelopes in a cool, dry location and avoid direct sunlight. The shelf life is 12 months.
- More Sturdy than Traditional Mailers: they are tear-resistant, puncture-resistant, and waterproof. Due to the strong self-adhesive glue, the recycled mailer cannot be opened once sealed before the whole packaging bag is torn up. You can count on our biodegradable padded poly mailers to keep your packages safe until they reach their destination.
- Suitable for Various Purposes: these padded packaging envelopes have a multi-purpose use, from offices to homes, shops, and schools. The anti-water paper surface easily accepts ink, stamps, and labels.
