Interior varnish routes can be reviewed for selected projects where minor oil exposure, paperboard behavior and sample testing need to be checked.

Self-Sealing Adhesive Strip
Self-sealing adhesive strip routes can be reviewed for packing workflow, seal method and fulfillment requirements after sample testing.

Tear-Open Strip (Zipper)
Tear-open strip routes can be reviewed for opening method, user experience and sample performance.

Project and Factory Documentation Review







Factory Certificates and Material Documentation Review
Ecoicolor can review available factory certificates, supplier documents and material-specific files where applicable. Claims related to BSCI, Sedex, FSC, GRS, ISO and Intertek should match the selected material, supplier, certificate scope and destination requirements.
Available factory, supplier and material documents can be reviewed where applicable. Material-specific documentation should match the selected substrate, production facility, certificate holder, validity period and destination requirements.

Quality Control Checkpoints for Mailer Projects
AQL Inspection Planning
AQL 2.5 / 4.0 inspection routes can be reviewed for selected production batches when agreed in the project requirements.
Project-Specific Quality Testing
In-house testing routes may include tensile strength checks, color fastness testing or material behavior review before bulk production, depending on material and order scope.
Pre-Shipment Inspection Planning
Drop tests, load-bearing checks and final visual inspection can be reviewed by order scope and agreed QC plan before shipment.
What Ecoicolor Can Verify Before Your Order
- MOQ is planned by product type: normally 500 for sewn bags and pouches, and 1,000 for paper boxes, rigid boxes, paper tubes, cartons and inserts.
- Sample approval can cover dimensions, material route, logo or print, product fit and packing before bulk production.
- FSC, recycled-content, paper source or mailer-route documents are discussed only when they match the selected material, supplier record and project scope.
- For review, send the product dimensions, quantity by item, target price, artwork status, ship-to country and launch window.

Frequently asked questions
Can I print on both the inside and outside of an e-commerce mailer?
Yes. Interior and exterior printing can be reviewed by board type, artwork coverage, color target, print method and sample result. Some routes may require separate plates, passes or setup steps.
Can e-commerce mailers be reviewed for 100ml glass essential oil bottles?
Yes. Bottle size, weight, insert structure, board type, packing route and test requirements should be reviewed with samples before bulk production.
Should I choose E-flute or B-flute for essential oil mailers?
E-flute is often suitable for cleaner printing and lighter essential oil kits, while B-flute can be reviewed for heavier kits or stronger shipping protection. Final choice depends on bottle weight, insert design, mailer size and transit requirements.
Can custom inserts be added inside the mailer?
Yes. Paperboard inserts, corrugated dividers, molded pulp and other insert routes can be reviewed based on bottle diameter, cap height, bottle count, drop protection and unboxing layout.
Can mailers include self-sealing or tear-open strips?
Self-sealing adhesive strips, tear-open zipper strips and tamper-evident routes can be reviewed by mailer structure, paper surface, packing process and sample performance.
What is the MOQ for custom printed e-commerce mailers?
For custom printed paper or corrugated mailer projects, MOQ is usually planned from 1000 units, depending on size, board type, print method, insert route and sample requirements.
