DuPont Surlyn® 1652 Zinc-Ionomer vs. Standard LLDPE in Acid & Essential-Oil Cosmetic Sachets
Compare DuPont Surlyn® 1652 zinc-ionomer against standard Ziegler-Natta and metallocene LLDPE when packaging Retinol, L-Ascorbic Acid (pH 2.5), Salicylic Acid, essential oils, and chemical sunscreens.
"When qualifying DuPont Surlyn® 1652 Zinc-Ionomer vs. Standard LLDPE in Acid & Essential-Oil Cosmetic Sachets (CMP-SUR-01) for Preventing Sachet Swelling & Delamination in Active Skincare Sampling, 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 / DuPont Surlyn® 1652 50 vs LLDPE 50 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: Dupont Surlyn 1652 Vs Standard Lldpe Cosmetic Sachets (PM-CS-227)
Consistent oxygen/moisture exclusion, seal-through contamination tolerance, and ±0.10 mm register accuracy govern how reliably Dupont Surlyn 1652 Vs Standard Lldpe Cosmetic Sachets performs from filling line to retail shelf. Under FlexPouchMFG™ production specification PM-CS-227, 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-227) | Lab Verification Standard |
