FAQ
Q1: What materials are used for the cement valve bags? A: The bags are made of high-strength polypropylene woven fabric and can be supplied with PE coating or lamination for improved moisture resistance.
Q2: What filling capacity can you provide? A: Common capacities include 20 kg, 25 kg, 40 kg and 50 kg. The bag dimensions can be customized according to the cement density and filling equipment.
Q3: Are the bags suitable for automatic filling machines? A: Yes. The valve opening is designed for high-speed automatic filling lines. The valve size and construction can be adjusted to match your filling spout.
Q4: How is the valve closed after filling? A: We can provide self-closing valves or heat-sealable valve sleeves. The appropriate option depends on your filling system and sealing requirements.
Q5: Are the bags moisture-resistant? A: Yes. Laminated or coated PP woven fabric helps protect cement from moisture during storage and transportation. An additional inner PE liner is also available if required.
Q6: Can you customize the bag size and valve dimensions? A: Yes. Bag width, length, bottom width, valve width and valve depth can all be customized according to your product and packing line.
Q7: Can you print our logo and product information? A: Yes. We support customized printing of logos, product names, technical information, safety instructions and barcodes. Flexographic and gravure-printed BOPP options are available.
Q8: How do the bags release air during filling? A: Air permeability can be controlled through the fabric structure and micro-perforation design. The perforation pattern can be customized to balance fast filling with dust control.
Q9: How do you confirm the bag specifications before production? A: We check the cement density, target filling weight, filling-spout dimensions, required air permeability and finished-bag dimensions before preparing samples or starting mass production.
Q10: Can you provide samples for testing? A: Yes. Samples can be provided for size checking, filling trials, sealing tests and drop tests before bulk production.
Q11: What quality inspections are carried out? A: We inspect bag dimensions, fabric weight, valve structure, printing quality, sealing strength and air permeability. Drop tests can also be conducted according to the agreed requirements.
Q12: What information is needed for a quotation? A: Please provide the bag size, filling capacity, fabric weight, lamination requirement, valve size, printing design, order quantity and destination port.
