How the Production and Quality Framework Works

Integrated manufacturing stages

The company’s production information describes a connected process spanning film blowing, printing, composite processing, cutting, and delivery. These stages make up its broader packaging manufacturing chain, which includes paper bags. The available information does not identify a separate inspection checkpoint for each stage.

Spot-check inspections

Spot-check inspection is identified for the company’s listed supply and service models. However, the published details do not define how often checks occur, how many items are sampled, which instruments or test methods are used, or what defect thresholds apply. Buyers should agree on these requirements for each order before production begins.

Certifications and traceability

The company holds ISO 9001 Quality Management System Certification, certificate number BMCQ0124208S, covering the manufacture of plastic and paper bags. Its FSC Chain of Custody certification, certificate number SAI-COC-012922, applies to paper sacks and bags. Both certifications are stated to apply globally within their respective scopes.
