ISO Class 8 Cleanroom GMP Cosmetic GMP · DuPont Surlyn® & Barex-Alt · MOQ FROM 1000 PCS ($0 DIGITAL PLATE)
High-Speed Multi-Lane Cosmetic Sachet Rollstock Film (PET/Al/BOPA/Surlyn® 1652 Foil Web for HFFS & VFFS)
FlexPouchMFG™ is a dedicated cosmetic barrier pouch manufacturer producing 1ml–15ml 4-side seal trial sachets, facial sheet mask pouches, hydrocolloid acne patch resealable envelopes, and hair mask packs. Engineered with 9μm soft-tempered AA8079 aluminum foil, chemical-resistant polyester adhesives, and DuPont Surlyn® ionomer or cyclic olefin (COC) sealants, our laminates survive 60-day accelerated stability testing at 50°C with pH 2.8 glycolic/salicylic acids, 20% L-ascorbic acid, retinol, and up to 18% volatile essential oils.
"Standard food-grade LDPE sachets delaminate within 14 days when filled with skincare formulas containing limonene, tea tree oil, salicylic acid, or chemical UV filters like avobenzone—because low-molecular-weight terpenes swell polyethylene and dissolve conventional polyurethane adhesives. We solve this permanently by pairing chemical-resistant epoxy-phenolic/aliphatic tie layers with a 50μm DuPont Surlyn® 1652 ionomer sealant."

1. Multi-Layer Polymer & Barrier Architecture: Cosmetic Sachet Rollstock Film 4 Side Seal HFFS VFFS (PM-RL-833)
Consistent oxygen/moisture exclusion, seal-through contamination tolerance, and ±0.10 mm register accuracy govern how reliably Cosmetic Sachet Rollstock Film 4 Side Seal HFFS VFFS performs from filling line to retail shelf. Under FlexPouchMFG™ production specification PM-RL-833, tension-balanced webs of 12µm Reverse-Printed PET (or 20µm BOPP) / 7µm AL or VMPET12 / 55µm High-Hot-Tack Metallocene LLDPE (74µm–95µm Precision Web) integrate with High-Contrast Photo-Eye Registration Mark (≥85% Contrast) + Optional Easy-Peel Lidding or Pattern Cold-Seal via 100% solventless Nordmeccanica lamination.
| Engineering Parameter | Specification (PM-RL-833) | Lab Verification Standard |
|---|---|---|
| Laminate Layer Stack | 12µm Reverse-Printed PET (or 20µm BOPP) / 7µm AL or VMPET12 / 55µm High-Hot-Tack Metallocene LLDPE (74µm–95µm Precision Web) | Optical Cross-Section Microtome (±3%) |
| Closure & Fitment System | High-Contrast Photo-Eye Registration Mark (≥85% Contrast) + Optional Easy-Peel Lidding or Pattern Cold-Seal | -0.080 MPa Underwater Vacuum Decay (ASTM D3078) |
| Heat-Seal Operating Window | 125°C–155°C High Hot-Tack (>4.5 N/15mm @ 0.1s) · 180–350 ms Fin/Lap Seal | Brugger HSG-C & Instron 5944 Peel (ASTM F88) |
| Barrier, COF & GC Purity | Controlled Kinetic COF μk = 0.19 ± 0.03 (ASTM D1894) · Slit Width ±0.15 mm · Camber <0.12% · 76mm/152mm Core | MOCON OX-TRAN 2/22, PERMATRAN-W & Agilent 8890 GC |
| Filling-Line Compatibility | Bosch / Syntegon, Rovema, Ilapak, Hayssen, Ishida & Fuji High-Speed VFFS / HFFS Flow-Wrappers (120–400 packs/min) | Dynamic Web/Pouch Flatness Camber <0.12% |
| Factory FOB Tiers & Packing | 300 kg: $6.20/kg ($0 plate) | 1,000 kg: $4.35/kg | 5,000+ kg: $3.85/kg (500 kg/pallet/ctn) | Double PE Liner + 5-Ply Carton + IPPC Pallet |
2. Filling-Line Mechanics & Heat-Seal Jaw Calibration
High-speed indexing on Bosch / Syntegon, Rovema, Ilapak, Hayssen, Ishida & Fuji High-Speed VFFS / HFFS Flow-Wrappers (120–400 packs/min) requires instant hot-tack strength and stable slip kinetics. Specification PM-RL-833 utilizes non-migrating slip additives and metallocene sealant resins so Cosmetic Sachet Rollstock Film 4 Side Seal HFFS VFFS runs smoothly without jaw sticking, tunnel wrinkles, or static powder bridging.
3. 500 kg Crossover Economics: HP Indigo Digital ($0 Plate) vs 10-Color Bobst Rotogravure
