Multi-layer color-printed valve-mouth putty woven packaging bags
Description:
Applicable materials:
Gypsum powder, cement, tile adhesive, grout, self-leveling mortar, leak-stopping compound, thermal insulation mortar, repair mortar, and other dry-mix construction materials.
Key features:
The valve opening is pre-formed, eliminating the need for manual bag support and reducing dust spillage by more than 90%. After filling, the valve seals automatically, obviating the need for additional sealing. The square-bottom design ensures stable stacking without tilting. A laminated outer film combined with an inner liner provides dual protection against moisture and leakage. Filling speed ranges from 6 to 15 seconds per bag, making it ideal for high-speed production lines.
Core Advantages:
High dust resistance (valve-mouth filling), high filling efficiency (6–15 seconds per bag), moisture and leak prevention, excellent tensile strength and puncture resistance, compatibility with high-speed filling lines, and no need for manual sealing.
Material and Craftsmanship:
The base material is woven fabric made of PP (polypropylene) or HDPE (high-density polyethylene), with a PE barrier film laminated on the inner layer (either as a laminated coating or as a co-extruded liner). The bag style is a square-bottom valve bag, with either a cuff-style or a flap-style valve. Printing is carried out using 2- to 7-color rotogravure color printing combined with lamination, resulting in vibrant, abrasion-resistant, and alkali-corrosion-resistant graphics.
Valve port structure:
Pre-formed valve mouth that automatically seals after filling, eliminating the need for additional sealing operations.
Applicable filling method:
Compatible with dedicated valve-fillers (impeller-type, screw-type, and pneumatic), ideal for high-speed rotary filling systems.
Tensile strength:
≥700 N/50 mm (30% above the national standard), suitable for stacking and transporting loads ranging from 10 to 50 kg.
Moisture resistance:
The water vapor transmission rate is reduced by more than 90% (due to the laminated film and inner-bag structure), effectively preventing the mortar from becoming damp, caking, and losing its effectiveness due to hardening.
Corrosion resistance grade:
★★★★★ (Highly resistant to the alkaline components of cement, the acidic components of gypsum, and additives).
Packaging drop test:
With a 50 kg load and a 1.2-meter free fall, the product remains intact and does not leak powder after being dropped from all six sides.
Printing Standards:
Solvent-resistant ink, compliant with building-material packaging labeling standards. 100% barcode/QR code scan rate.
Customization Scope:
Multi-color overprinting of the brand logo, product name, net content, implementation standards, application instructions, and mixing ratio recommendations. Warning labels (e.g., “Moisture-Resistant,” “Drop-Resistant”), barcodes, QR codes, metrology labels, and environmental recycling symbols may also be added.
Environmental Compliance:
Made from virgin materials and recyclable. Supports hazardous packaging export certification.
Packaging specifications:
Customizable: loading weight (10 to 50 kg), bag dimensions (length × width × bottom width), valve opening size (80–120 mm), number of inner bag layers, and print area.
Applicable to:
Dry-mix mortar manufacturers, putty powder plants, gypsum powder processing enterprises, tile adhesive producers, self-leveling material manufacturers, and building-materials export traders.
Price and Minimum Order Quantity:
Negotiable; inquiries welcome.
