Important scope notes: ISO 9001:2015 is not used as an active claim because the provided certificate expired on May 22, 2026. View ISO renewal note image. FDA approval-style wording is not used; food-contact wording is limited to material or migration-test documentation. FSC and SGS marks are handled through document evidence and authorized certificate/report images rather than unsupported decorative logo use.
Production Process Buyers Should Verify
| Step | What Buyers Should Confirm |
|---|---|
| Specification review | Product type, size, material, barrier, closure, printing, filling method, shelf-life target, and market requirements. |
| Material preparation | Film, paper, ink, adhesive, coating, zipper, spout, valve, or fitment details are confirmed before production. |
| Printing and converting | Printing, lamination, curing, slitting, pouch making, cup forming, or roll-stock conversion according to the confirmed structure. |
| In-process QC | Thickness, color, registration, lamination, seal, dimension, and function checks during production. |
| Final inspection | Random sampling, visual review, packing check, carton labeling, and export packing confirmation. |
EEAT Asset Checklist
| Evidence Type | What Should Be Published or Prepared |
|---|---|
| Factory photos | Factory exterior, signage, workshop, warehouse, packing area, and export cartons. |
| Production lines | Printing, lamination, slitting, pouch making, paper cup forming, spout/valve application, and packing lines. |
| QC images | Thickness gauge, seal test, color sample, zipper/spout test, final sampling, and material inspection. |
| Certificates and reports | Only valid documents issued to XIYONG PACK or applicable material/supplier scope should be published. |
| Video evidence | Short production, packing, and inspection clips can improve buyer confidence when owned by XIYONG PACK. |
Documentation by Packaging Type
| Packaging Project | Documents and Checks to Prepare |
|---|---|
| Food packaging | Food-contact declarations, material specifications, ink/adhesive/coating scope, and supplier documents where applicable. |
| Recyclable packaging | Material structure, recyclability rationale, mono-material design notes, and local claim review. |
| Coffee packaging | Barrier structure, valve specification, aroma/oxygen protection logic, and sample approval record. |
| Pet food packaging | Grease resistance, odor barrier, puncture resistance, zipper function, and shelf-life assumptions. |
| Frozen food packaging | Cold resistance, seal reliability, puncture resistance, and packing-line compatibility. |
Quality Control Checkpoints
Material QC
Material thickness, film appearance, paper board quality, coating condition, and material structure should be checked before conversion.
Printing QC
Print registration, color consistency, barcode readability, surface finish, and artwork version should be verified before mass output.
Functional QC
Seal strength, zipper function, spout or valve bonding, pouch dimensions, puncture resistance, and packing-line compatibility should be reviewed.
Final Packing QC
Finished goods should be checked for appearance, quantity, carton labeling, export packing, and sample retention before shipment.
Important Trust Rule
XIYONG PACK should publish only its own factory photos, production images, QC images, certificates, and test reports. Competitor images and certificates may be used internally as references for what evidence buyers expect, but they should not be presented as XIYONG-owned assets.

FAQ
What factory evidence should packaging buyers request?
Buyers should request factory photos, production-line images, warehouse photos, packing evidence, and QC process records that match the product being sourced.
What QC checks matter for flexible packaging?
Important checks include material thickness, print registration, color consistency, lamination quality, seal strength, pouch dimensions, zipper or spout function, and final random sampling.
Should buyers ask for certificates before ordering?
Yes. Buyers should ask for valid certificates or test reports before bulk production, especially for food-contact, recyclable, or destination-market requirements.
Can one certificate cover every packaging product?
No. A certificate or report must be reviewed against its issuing entity, material scope, product structure, date, and intended use.
What should be included in a sample approval record?
A sample approval record should include material structure, size, thickness, print finish, closure, artwork version, test notes, and buyer approval date.
Why are production line photos useful?
Production line photos help buyers confirm that a supplier has relevant converting, printing, laminating, slitting, pouch-making, paper cup forming, or packing capability.
How does XIYONG PACK use trust evidence on the website?
XIYONG PACK should publish only owned factory images, verified documents, and accurate process descriptions, while using competitor assets only as internal reference.
What information should buyers send before QC planning?
Buyers should send product type, packing format, material target, order quantity, filling method, destination market, and shelf-life or compliance requirements.
