Ordinary woven bags allow moisture, air, and dust to penetrate, leading to product spoilage, weight loss, or contamination. For overseas buyers in tropical, humid, or long-distance sea freight conditions, this is a major risk.
Our PP Woven Bags with Built-in Liner solve this problem completely. We combine a high-strength PP outer layer with a customizable inner liner (PE, Alu Foil, or Laminated Film) to create an airtight, moisture-proof, and leak-proof packaging solution.
Whether you are packaging rice, sugar, flour, animal feed, chemical powder, or seeds, our bags ensure product freshness, safety, and extended shelf life – even under high humidity or long-term storage.

The inner PE/Alu liner is fully heat-sealed or folded, creating a complete barrier against humidity, oxygen, and insects. The PP outer layer provides puncture resistance. Perfect for sea freight to Africa, Southeast Asia, and South America.
Both outer PP and inner liner use virgin, non-toxic materials. No recycled content touches your product. Suitable for direct contact with human food and animal feed. Odorless and safe.
Unlike single-layer woven bags that leak fine powders (flour, cement, chemicals), our liner prevents any dust leakage. Your products arrive clean without waste – reducing customer complaints.
PE Liner: General moisture-proof, cost-effective.
Aluminum Foil Liner: Ultimate oxygen/light barrier for coffee, spices, or high-value seeds.
Laminated Liner: Enhanced strength and printing surface.
Our block bottom & valve bag style with liner can be used on automatic filling lines (e.g., rice mills, sugar refineries). Heat-sealed liner prevents wicking.
Direct factory supply without middleman profit. Large inventory supports urgent orders and full-container export. Complete export documents support global customs clearance.
✅ Food Industry: Rice, sugar, flour, beans, salt, coffee beans, spices, pet food.
✅ Agriculture: Seeds, animal feed, grain storage, fertilizer.
✅ Chemicals: Powder chemicals, resin, pigment, cement additive (powder form).
✅ Emergency & Logistics: Disaster relief food packaging, long-term warehouse storage.
Q1: What types of inner liners do you offer?
A1: We offer 3 main types – PE liner (standard moisture-proof), Aluminum Foil liner (oxygen/light barrier), and Laminated liner (high strength). Double-layer liners are also available.
Q2: Can the inner liner be fully sealed?
A2: Yes. For open-mouth bags, we recommend heat-sealing the liner after filling. For valve bags, the liner is pre-sealed automatically during filling. This creates a 100% airtight package.
Q3: Are these bags suitable for powdered products (e.g., flour, milk powder)?
A3: Absolutely. The inner liner prevents fine powder leakage (dusting) – a common problem with ordinary woven bags. Your factory stays clean and product weight remains accurate.
Q4: Do you offer UV protection for the outer PP layer?
A4: Yes. If the bags will be stored outdoors for a long time (e.g., construction sites, open warehouses), we can add UV stabilizers to the outer layer to prevent cracking and fading.
Q5: Can you print my brand logo and product information?
A5: Yes. We support full-color multi-wall printing on the outer PP layer (BOPP lamination or flexo print). Usage instructions or local language labels are also available.
Q6: What is your MOQ for liner bags?
A6: For standard PE liner with printed outer bag, MOQ is 10,000 pcs. For sample testing, we can produce 500 pcs trial order. Free sample available (buyer pays freight).
Q7: How do you ensure the liner is not damaged during filling?
A7: We can add an inner liner tacking point (spot adhesion) to keep the liner attached to the outer bag – preventing slippage and tearing during high-speed automatic filling.
