What Can Be Customized on Compostable Mailers?
A custom mailer should be designed around the product being shipped, the fulfilment process and the required customer experience.
ORIZON can review the complete mailer specification rather than only changing the printed logo.
| Specification | Custom Options |
|---|---|
| Mailer Width | Custom |
| Mailer Length | Custom |
| Thickness | Based on shipment and application |
| Flap Length | Custom |
| Seal Structure | Open top / single adhesive / dual adhesive |
| Return Strip | Available for suitable structures |
| Film Color | Natural / white / black / custom |
| Opacity | Translucent / opaque depending on formulation |
| Printing | Unprinted / custom logo |
| Printing Side | One side / two sides |
| Print Color | Pantone reference |
| Tear Strip | Custom where applicable |
| Packing | Flat packed / bundled / custom |
| Carton Quantity | Custom |
| Carton Marking | Custom |
| Private Label | Available where required |
Mailer size, thickness, flap and adhesive structure should be confirmed together because each factor can affect sealing, packing efficiency and the usable printing area.

Custom Compostable Mailer Styles
Different e-commerce workflows require different mailer structures.
Custom Self-Adhesive Mailers
Self-adhesive mailers are widely used for outbound e-commerce and courier shipments.
Typical custom options include:
- width and length
- thickness
- flap length
- adhesive strip
- film color
- opacity
- logo printing
- carton quantity
The flap and adhesive position should be confirmed together with the mailer dimensions so the bag can be filled and sealed efficiently.
Custom Dual-Seal Return Mailers
Dual-seal mailers use two adhesive strips so the same bag can support both outbound shipping and customer returns.
They are useful for:
- apparel brands
- DTC businesses
- fashion e-commerce
- subscription businesses
- return-enabled fulfilment programs
Important specifications include:
- flap length
- first adhesive strip
- second adhesive strip
- spacing between seals
- tear or opening area
- film thickness
- artwork position
The return workflow should be considered before finalizing the flap and printing layout.
Customisation options may include
- Custom bag sizes and thickness ranges
- Flat or self-sealing mailer structures
- Dual-seal / return mailer configurations
- Opaque or coloured finishes
- Custom printed branding (logo, messaging, repeat patterns)
- Bulk carton packing for wholesale distribution
Our team reviews every project for material suitability, print coverage, and production feasibility before mass production.
Custom Mailer Size & Thickness
Mailer dimensions should match the products being shipped rather than relying only on a standard courier-bag size.
Custom Mailer Size
Size selection may depend on:
- apparel dimensions
- folded garment size
- accessories
- soft goods
- boxed products
- product quantity per mailer
- packing method
Oversized mailers can increase material and freight use, while undersized mailers can create sealing or loading problems.
If you already use a conventional plastic mailer, the existing specification can be used as a reference.
Custom Thickness
Thickness should be selected according to:
- mailer dimensions
- product weight
- sharp edges
- handling conditions
- shipping distance
- privacy requirements
- return use
- adhesive structure
A thicker mailer uses more material and may provide additional durability, but the best specification should balance performance, weight and cost.
Thickness should therefore be selected according to the shipment application rather than by bag size alone.
Custom Adhesive Seal & Flap
The sealing system is one of the most important parts of a custom compostable mailer.
Adhesive Strip
The adhesive system should be reviewed according to:
- mailer size
- flap length
- filling method
- shipping conditions
- single-use or return use
- release-liner requirements
Adhesive position and width should be confirmed before artwork is finalized.
Flap Length
Flap length affects how easily the mailer can be filled and sealed.
A suitable flap should provide enough working area for:
- adhesive placement
- sealing
- opening
- artwork clearance
- return-strip configuration where required
Return Strip
For return mailers, a second adhesive strip can allow the customer to reseal the bag after opening.
The return design should consider:
- spacing between adhesive strips
- opening position
- tear line
- flap length
- user instructions
- artwork placement
The relationship is:
Mailer Size
- Flap Length
- Adhesive Position
- Return Strip
- Sealing Workflow
Custom Film Color & Privacy
Film color and opacity are especially important for e-commerce shipments.
Typical options may include:
- Natural
- White
- Black
- Custom Color
Depending on the project, increased opacity may be required to reduce visibility of the contents during transport.
Film appearance can be influenced by:
- material formulation
- thickness
- color masterbatch
- printing coverage
For apparel and consumer shipments, privacy requirements should be considered together with film color and thickness.
Custom color references can be reviewed using Pantone targets where applicable.
Custom Printed Compostable Mailers
Custom logo printing is available for compostable e-commerce and shipping mailers.
Custom logo printing is available for compostable e-commerce and shipping mailers.
Typical printed content may include:
- logo
- brand name
- website
- social handle
- shipping instructions
- return instructions
- environmental messaging
- approved certification marks
- multilingual text
Printing should normally be planned after the mailer size, flap, adhesive and film color are confirmed.
Logo & Brand Printing
Brand artwork can be positioned on the main body panel according to the available print area.
For return mailers, additional instructions may also be required near the opening or resealing area.
Single-Side or Double-Side Printing
Projects can be reviewed for:
- single-side printing
- double-side printing
The appropriate setup depends on the artwork and mailer structure.
Pantone Print Colors
Pantone references can be used as print-color targets.
Final appearance may vary according to:
- film color
- opacity
- thickness
- ink
- print coverage
A logo printed on black or opaque film may require a different approach from the same artwork printed on natural or white film.
Print Area & Flap Clearance
The total mailer size is not the same as the usable printing area.
Artwork should allow sufficient clearance around:
- flap
- adhesive strip
- folding area
- tear strip
- opening area
- bag edges
The useful relationship is:
Mailer Width
- Flap & Seal Area
- Usable Body Panel
- Logo Size & Position

Certification for Custom Compostable Mailers

Relevant standards may include:
| Market | Common Standard / Program |

| Europe | EN 13432 |
| Australia | AS 4736 / AS 5810 |

Certification marks should only be printed where the applicable certification scope and logo-use authorization allow it.
