Value-added Services

We are honored to offer one-stop FIBC and liner procurement services, ensuring end-to-end control from material selection to final delivery for optimal cargo protection and logistics efficiency.

I. Core Package Solutions (by Functional Scenario)  

1.  Basic Moisture-proof Type:  

- FIBC: PP woven fabric (80-150gsm), 1-2t SWL.  

- Liner: PE liner with both ends open / one end open.  

- Application: Bulk goods with standard moisture protection needs (e.g., cement, grain, fertilizer).  

2.  Premium Protective Type:  

- FIBC: Laminated PP woven fabric (with anti-leak cotton tape), anti-static additive.  

- Liner: Aluminum foil composite (PET/AL/PE structure).  

- Application: Products requiring light-blocking/moisture/static control (e.g., battery materials, chemical powders, pharmaceutical raw materials).  

3.  Food-Grade Clean Type:  

- FIBC: Food-grade PP woven fabric (FDA-certified), bottom discharge spout design.  

- Liner: Food-grade PE film (EU 10/2011 compliant), with tear notch.  

- Application: Direct food-contact packaging (e.g., milk powder, starch, feed).  

4.  Special Functional Type:  

- FIBC: Flame-retardant PP woven fabric (UL 94 HB-rated), UV-resistant treatment.  

- Liner: Chemical-resistant PE film (pH 2-12 tolerance).  

- Application: Corrosive goods (e.g., fertilizer, pesticides, liquid chemicals).  

II. One-Stop Service Advantages  

1.  Cost Optimization:  

- FIBC-liner co-design prevents size mismatches during assembly, reducing material waste.  

2.  Quality Assurance:  

- Provide third-party test reports (e.g., tensile strength, hermeticity, puncture resistance) or other required certifications.  

3.  Delivery Efficiency:  

- Procuring bundled solutions from us significantly improves your sourcing efficiency.  

- Hengchang Packaging handles all post-delivery quality guarantees and after-sales services.  

4.  Customization Capabilities:  

- Support logo printing (up to 5 colors), special valve designs (e.g., one-time discharge spout locks).

We provide customized packaging solutions based on cargo properties, transport modes, and storage environments, covering end-to-end services from material selection to structural design. Below are the detailed workflow and core advantages:  

● Needs Diagnosis Phase (1-2 working days)

1.  Provide cargo parameters: density, particle size, corrosivity, hazardous class, etc.  

2.  Transport requirements: sea/air/land freight, etc.  

3.  Storage conditions: temperature, humidity, stacking tiers, etc.  

4.  Compliance certifications: FDA, UN, EU food-grade, etc.  

5.  If available, provide photos/videos of competing product packaging or existing issues (e.g., high breakage rate, difficult discharge) for targeted optimization.  

● Solution Design Phase (3-5 working days)  

We provide 1-2 tailored solutions (e.g., economy vs. premium protection), including:  

1.  Structural CAD drawings (with production process details).  

2.  Material comparison table: PP woven fabric gsm, PE liner thickness, certification levels, cost differences.  

3.  Performance parameter sheet: Modeled estimates for SWL test values, leakage resistance, UV resistance duration.  

● Sampling Phase (7-10 working days)

1.  Rapid prototyping: Deliver 1:1 physical samples (FIBC + liner combo).  

2.  Custom features: e.g., FIBC side inspection windows, static-dissipative liner coating.  

3.  Custom markings: Logo printing, batch number coding, hazard warning icons.  

● Testing & Optimization Phase (5-7 working days)  

Lab tests per your requirements:  

- Lifting tests  

- Drop tests  

- Hermeticity tests  

- Temperature resistance tests  

- Puncture resistance tests  

- UV aging tests  

- Stacking compression tests  

- Compliance spot checks  

(Test fees negotiable)

● Solution Confirmation Phase (1-3 working days)  

Final delivery: Sign 《Packaging Solution Confirmation Form》 including:  

- Final stamped drawings  

- Quality Commitment Letter (mass production ≤3% deviation from samples)  

- Cost optimization proposals (e.g., alternative liner materials: 12% cost reduction with 20% protection decrease).  

For designing FIBC packaging compliant with international environmental requirements, Hengchang Packaging focuses on material selection, sustainable design, and certification compliance.  

● Preferred Eco-friendly Materials & Processes  

1.  Primary material: Hengchang Packaging uses 100% virgin recyclable polypropylene. If customers require recycled content, we produce FIBCs with recycled material to reduce virgin plastic consumption.  

2.  Auxiliary materials: Liners, printing inks, sewing threads, etc., are synchronously compliant (e.g., water-based inks, heavy-metal-free coatings).  

3.  Production optimization: Adopt low-energy extrusion tape technology to reduce carbon emissions. Scrap is crushed and recycled for closed-loop production.  

● Functional & Sustainable Structural Design  

1.  Optimize bag structure (e.g., base fabric gsm, loop SWL design) to minimize material use while meeting load standards. Avoid overdesign (e.g., redundant lamination/coatings) to simplify recycling.  

2.  Provide detachable liners and outer bags for segregated recycling. Minimize material composites to ensure mono-material recyclability.  

3.  Offer reusable designs: Add abrasion-resistant coatings, reinforce stress points, and extend service life for multi-rotation scenarios.  

● Full-cycle Compliance & Certification  

Hengchang Packaging assists customers in meeting regional eco-tax incentives by providing required tests and certifications, including:  

- GRS (Global Recycled Standard)  

- RCS (Recycled Claim Standard)  

- EPD (Environmental Product Declaration)  

- LCA (Life Cycle Assessment) reports  

- Target market-specific certifications (e.g., EU REACH, US TSCA)
