Color‑Printed Valve Sack For Wall Putty Powder

Heshengyuan Packaging Materials (Xuzhou) Co., Ltd. manufactures premium Valve Sacks, high‑quality Industrial packaging bags. This color‑printed valve sack is specially designed for packing wall putty, gypsum powder, dry‑mix mortar and other decorative construction powders. Fitted with a corner valve spout, it perfectly matches automatic powder‑filling production lines. The sack seals itself by internal pressure once filled, which greatly cuts dust emission during filling and prevents powder leakage during storage, stacking and ocean transportation.
