Calibrated Peeling Frangible Middle Seal (12–18 N/15mm) · Outer Seal ≥52 N/15mm · MOQ FROM 500 PCS ($0 DIGITAL PLATE)
Twin-Chamber (Wet/Dry or Part A/Part B) Dual-Compartment Cosmetic & Medical Sachets
Separate incompatible actives—such as L-Ascorbic Acid powder + Hyaluronic serum, hair dye + developer, or dry sheet mask + fresh ampoule—until the moment of use via our Dual-Chamber sachets with center frangible burst seals or twin tear notches.
"When qualifying Twin-Chamber (Wet/Dry or Part A/Part B) Dual-Compartment Cosmetic & Medical Sachets (FP-SAC-DUAL) for Dual-Phase Vitamin C Serums, Hair Colorants, Wet/Dry Masks & Diagnostic Kits, 90% of field failures occur at the heat-seal interface due to product contamination or differential web shrinkage. By pairing our PET 12 / AL 9 / BOPA 15 / Peeling Burst-Seal Co-Ex PE 65 structure with solventless polyurethane curing at 52°C and precision Totani ultrasonic gusset tamping, we guarantee ≥48 N/15mm seal strength and <0.5 mg/m² GC residual solvents on every shipment."

1. Multi-Layer Polymer & Barrier Architecture: Twin Chamber Dual Compartment Burst Serum Sachet (PM-CS-897)
Consistent oxygen/moisture exclusion, seal-through contamination tolerance, and ±0.10 mm register accuracy govern how reliably Twin Chamber Dual Compartment Burst Serum Sachet performs from filling line to retail shelf. Under FlexPouchMFG™ production specification PM-CS-897, tension-balanced webs of 12µm Matte or Holographic PET / EAA Acid-Copolymer Tie / 9µm Soft-Annealed Pure AL / 50µm DuPont™ Surlyn® 1652 Zinc Ionomer (83µm) integrate with Precision Laser-Scored Easy-Tear Line (3-Side, 4-Side, Dual-Chamber Twin, or Shaped Bottle Dieline) via 100% solventless Nordmeccanica lamination.
| Engineering Parameter | Specification (PM-CS-897) | Lab Verification Standard |
|---|---|---|
| Laminate Layer Stack | 12µm Matte or Holographic PET / EAA Acid-Copolymer Tie / 9µm Soft-Annealed Pure AL / 50µm DuPont™ Surlyn® 1652 Zinc Ionomer (83µm) | Optical Cross-Section Microtome (±3%) |
| Closure & Fitment System | Precision Laser-Scored Easy-Tear Line (3-Side, 4-Side, Dual-Chamber Twin, or Shaped Bottle Dieline) | -0.080 MPa Underwater Vacuum Decay (ASTM D3078) |
| Heat-Seal Operating Window | 115°C–138°C Low-SIT Contamination-Through-Oil Seal · 350 ms · 0.26 MPa (<0.3 N/15mm Decay after 50°C×12wk Aging) | Brugger HSG-C & Instron 5944 Peel (ASTM F88) |
| Barrier, COF & GC Purity | Inner COF 0.21 · GC Residual Solvent <0.20 mg/m² · OTR ≤0.010 cc/m²·24h · WVTR ≤0.010 g/m²·24h | MOCON OX-TRAN 2/22, PERMATRAN-W & Agilent 8890 GC |
| Filling-Line Compatibility | Bossar / Brodrene Hartmann / Siebler / Merz Cleanroom Horizontal 4-Side-Seal Sachet & Sheet-Mask Filling Lines (80–240 pcs/min) | Dynamic Web/Pouch Flatness Camber <0.12% |
| Factory FOB Tiers & Packing | 500–2,500 pcs: $0.046/pc ($0 plate) | 10,000 pcs: $0.024/pc | 50,000+ pcs: $0.018/pc (3,000/ctn) | Double PE Liner + 5-Ply Carton + IPPC Pallet |
2. Filling-Line Mechanics & Heat-Seal Jaw Calibration
High-speed indexing on Bossar / Brodrene Hartmann / Siebler / Merz Cleanroom Horizontal 4-Side-Seal Sachet & Sheet-Mask Filling Lines (80–240 pcs/min) requires instant hot-tack strength and stable slip kinetics. Specification PM-CS-897 utilizes non-migrating slip additives and metallocene sealant resins so Twin Chamber Dual Compartment Burst Serum Sachet runs smoothly without jaw sticking, tunnel wrinkles, or static powder bridging.
3. 15,000 Crossover Economics: HP Indigo Digital ($0 Plate) vs 10-Color Bobst Rotogravure
