Multi-layer color-printed woven flat bags for building materials
Category:
Description:
Applicable materials:
Putty powder, cement, gypsum powder, quartz sand, dried sand, dry-mix mortar, thermal insulation mortar, and other dry/particle building materials.
Core Advantages:
Cost-effectiveness: Highly versatile and flexible for filling, suitable for manual, semi-automatic, and fully automatic production lines.
Beautiful printing: multi-color printing with lamination for excellent brand presentation.
Material and Craftsmanship:
Base material: PP (polypropylene) / HDPE (high-density polyethylene) woven fabric
Structure: Multi-layer composite = PP/HDPE woven fabric + PE barrier film (laminated) + optional inner bag (PE/aluminum foil)
Bag Type: Flat Open Mouth Bag
Bottom style: sewn bottom / heat-sealed bottom / ultrasonic-sealed bottom
Printing: 2–7-color gravure color printing with laminating, offering excellent resistance to abrasion and alkaline corrosion from cement.
Sealing methods: sewing (thread stitching), heat sealing (requires an inner bag), and tying (for small packages).
Applicable filling methods: screw fillers, impeller fillers, pneumatic fillers, gravity fillers, and manual filling (semi-automatic line).
Tensile strength: ≥700 N/50 mm, suitable for stacking under a 25–50 kg load and for long-distance transportation.
Moisture-proof performance: Water vapor transmission rate reduced by more than 90% (with lamination and inner bag), ensuring that putty powder remains free of caking for up to 6 months.
Corrosion resistance rating: ★★★★★ (highly resistant to cement alkalinity, gypsum acidity, and putty powder additives)
Packaging drop test: 50 kg load, 1.2-meter free fall—no breakage and no powder leakage after drops on all six sides.
Printing standards: solvent-resistant ink with alkali resistance, compliant with building-material packaging labeling standards, and achieving a 100% barcode/QR code scan success rate.
Customization Scope: Multi-color overprinting (brand logo, product name, installation instructions, mixing ratio table); warning labels (“Moisture-Resistant,” “Drop-Resistant,” “Keep Away from Acids and Alkalis”); barcodes/QR codes (for traceability and anti-counterfeiting); measurement markings (20 kg/25 kg/40 kg scale lines); and environmental recycling labels.
Environmental Compliance: Made from virgin materials, odorless and dust-free, recyclable, and compliant with hazardous packaging export certification.
Key features:
Easy to open: flat-mouth design for convenient manual or machine bagging.
Easy filling: neat bag opening, smooth insertion of the filling nozzle
Easy to seal: Compatible with a variety of sealing equipment (sewing machines/heat sealers).
Leak-proof: Double barrier with laminated film and inner pouch
Moisture Resistance: Water Vapor Barrier Rate ≥ 90%
Stacking Stability: Bags are flat and neatly stacked on pallets.
Anti-aging: UV stabilizers can be added (optional); remains flexible outdoors.
Packaging specifications:
Customizable (weight range, valve opening size, bag body dimensions, number of inner layers: no inner layer / single-layer PE / double-layer PE / aluminum foil layer).
Printing area:
Single-sided / Double-sided / Full-color
