Build specification
We match the material to the job, drawing on six grades of board: Kraft, Corrugated, Coated Art Board (C1S), Rigid Greyboard, Solid Bleached Sulfate (SBS), and Metallic. Together they span the whole range — kraft for eco-minded artisan brands, heavy greyboard for luxury rigid boxes, and bright SBS for cosmetics, pharmaceutical, and high-end retail packaging. A small business chasing affordable corrugated mailers and a premium label after the weighty snap of a magnetic-closure box draw from the same FSC-certified supply, chosen to look right on shelf, survive transit, and impress at the moment of unboxing.
Finish is the detail customers feel, so we cover every option: soft-touch matte lamination, high-gloss lamination, silk lamination, spot UV coating, gold and silver foil stamping, embossing, debossing, and aqueous coating. Spot UV sets a glossy highlight against matte to steer the eye to your logo; soft-touch lamination gives rigid boxes a velvety surface that says premium before the box is opened. On SBS or coated art paper, foil stamping produces the crisp metallic accents that luxury cosmetic, fragrance, and gifting brands count on to back up their pricing and spark the kind of unboxing people share online.
Paper weight shapes two things at once: how the box sits in the hand and how it fares in transit. We run the whole scale from lightweight 8pt to heavyweight 28pt, using the point system common to US and UK suppliers. For folding cartons and high-volume retail boxes, 8pt–12pt does the job; for most product packaging, 14pt–18pt is the dependable workhorse — strong enough to protect, light enough to keep shipping costs down. And 20pt–28pt brings the rigid, substantial feel that luxury gift boxes, rigid set-up boxes, and premium cosmetic packaging rely on, where the box's weight signals quality before the lid is lifted.
Custom Compostable Mailers for Sustainable Programs
Custom compostable mailers serve a rapidly growing sustainable packaging category where sustainable brand shipping programs, eco-conscious ecommerce operations, green DTC distributions, and certified sustainable brands all require packaging delivering genuine end-of-life environmental benefit beyond the greenwashing of recyclable claims that conventional plastic mailers often make. The compostable mailer category provides the authentic sustainability solution for ecommerce brands seeking certified environmental credentials for their packaging programs supporting supply chain sustainability commitments and eco-conscious customer expectations.
Certified Compostable Construction
Certification quality defines compostable mailer credibility because consumer and regulatory scrutiny of environmental packaging claims requires third-party verified compostability certification rather than unsubstantiated marketing claims. Our compostable mailers use certified compostable biopolymer film meeting EN 13432 European compostability standard or ASTM D6400 North American compostability standard verified through independent certification bodies. Industrial compostable certification requires commercial composting facility conditions. Home compostable certification breaks down in typical home compost conditions providing broader end-of-life accessibility for customers without composting facility access.

- ASTM D6400 North American certification
- Industrial and home compostable options
- Third-party verified certification bodies
Functional Performance for Ecommerce
Functional performance defines compostable mailer viability for ecommerce shipping programs because sustainable packaging must protect products through shipping cycles while maintaining compostability credentials. Our compostable mailers provide moisture resistance protecting shipped products during outdoor carrier delivery comparable to conventional poly mailer performance. Self-seal adhesive closure maintains shipping security during carrier handling. Adequate strength and tear resistance handles typical ecommerce carrier sortation and delivery handling. Many sustainable ecommerce brands report compostable mailer functional performance equivalent to conventional poly mailer alternatives for appropriate product weight and fragility categories.

Sustainability Marketing Integration
Sustainability marketing integration drives compostable mailer value for eco-conscious brands communicating environmental commitments through packaging choices. Compostability certification documentation supports third-party sustainability claims in brand marketing across website, social media, and product packaging. Many sustainable ecommerce brands report that compostable mailer programs directly improve customer brand perception scores among eco-conscious customer segments willing to pay premium pricing for brands demonstrating genuine environmental commitment through certified packaging programs.
Custom Printing on Compostable Mailers
Custom printing on compostable mailers uses compostable-compatible printing processes maintaining certification integrity while delivering brand visual identity. Plant-based ink printing on compostable mailer surfaces maintains complete supply chain compostability certification. Many sustainable brands use compostable mailer printing for brand logos, sustainability certification icons, composting instruction messaging, and brand storytelling connecting customers to sustainable supply chain commitments. The combination of certified compostable construction and sustainable printing creates complete supply chain sustainability credentials for environmental brand programs.

FAQs
01 What is the difference between industrial and home compostable?
Industrial compostable certification requires commercial composting facility conditions including high temperature and humidity maintained in industrial compost processing. Home compostable certification breaks down in typical backyard home compost conditions providing broader accessibility for customers without composting facility access. Many sustainable brands choose home compostable certification because broader end-of-life accessibility ensures more customers can properly compost rather than landfill mailer packaging.
02 Are compostable mailers as durable as conventional poly mailers?
Yes for appropriate product categories. Our compostable mailers provide moisture resistance, self-seal security, and tear resistance comparable to conventional poly mailer alternatives for standard ecommerce product weight and fragility categories. Many sustainable ecommerce brands report compostable mailer performance equivalent to conventional poly for fashion, beauty, lifestyle, and light product shipping programs.
03 What certifications do compostable mailers carry?
EN 13432 European compostability standard and ASTM D6400 North American compostability standard verified through independent certification bodies. Certification documentation supports third-party sustainability claims in brand marketing. Many sustainable retail partnerships require certification documentation for green packaging program approval. Home compostable options carry additional certification from recognized home compostability programs.
04 Can compostable mailers include brand printing?
Yes. Plant-based ink printing on compostable mailer surfaces maintains complete supply chain compostability certification. Many sustainable brands print compostable mailers with brand logos, sustainability certification icons, composting instruction messaging, and brand storytelling. The combination creates complete sustainability credentials while delivering brand visual identity supporting eco-conscious ecommerce marketing programs.
05 What is the minimum order for custom compostable mailers?
Our MOQ for custom compostable mailers starts at 100 units. This accessible MOQ supports emerging sustainable brand startups, indie eco-conscious operations, and craft brand concepts.
