Our latest Austrian Starlinger starKON AX+ line is now running, raising block-bottom valve bag output and tightening print registration for export orders.
The new Austrian Starlinger starKON AX+ block-bottom bag making line entered production in October 2026. Running at up to 120 bags per minute, it raises our monthly valve-bag output by 2.5 million pieces and tightens print registration to within 0.5 mm. This directly supports our export orders to West Africa, Southeast Asia and the Middle East, where multi-color gravure printing and consistent bag dimensions are mandatory for automatic cement filling lines.
Another container of multilingual (French + Arabic) 32.5R cement valve bags shipped to West Africa, manufactured to EN 197-1.
In September 2026 we completed a 40-foot container of 32.5R CEM II/B-L cement valve bags for Ciment de Mauritanie. Printed in both French and Arabic, the bags conform to EN 197-1 European cement standard and feature 4-color gravure printing on laminated PP woven fabric.

We passed the annual SGS audit, renewing our "Made in Zhejiang" certification and AAA-grade enterprise credit rating.
In July 2026, SGS auditors conducted the annual surveillance audit and renewed our "Made in Zhejiang" certification, valid through 2029. We also maintained our AAA-grade enterprise credit rating. The audit covered raw material sourcing, production process, product testing, and export documentation systems — confirming our capability as a qualified export packaging supplier.
Expanded production of light-blue printed dry-mix mortar bags, adding moisture-resistant laminated options for the building-materials segment.
In June 2026 we expanded our dry-mix mortar bag production line for Carpoly (Jiabao Li Building Coatings). The new light-blue printed bags feature moisture-resistant PE lamination and are sized for 20kg and 25kg ready-mix mortar packaging. This expansion reflects growing demand from building-materials customers for premium-printed, moisture-resistant valve bags beyond traditional cement.
A practical guide for buyers: heat-seal vs. sewn, grammage, print colors, safety factor and why factory-direct beats trading companies.
When choosing a cement valve bag supplier, buyers should verify: (1) heat-sealed block-bottom construction vs. sewn valve — heat-seal is dust-free and automatic-filling friendly; (2) grammage — 65-80 g/m² laminated woven for export, heavier for harsh climates; (3) print capability — up to 8-color gravure for your brand; (4) safety factor for FIBC — 5:1 single-trip, 6:1-8:1 reusable; (5) whether the supplier owns extrusion and weaving equipment in-house. Factory-direct sourcing eliminates middleman markups and gives direct quality control.
