In the world of high-volume e-commerce, every micron of packaging thickness and every gram of parcel weight matters. While many brands focus solely on the unit price of a mailer, savvy supply chain managers look at the Total Cost of Ownership (TCO). At PAC·ZELON, we utilize advanced 3-layer co-extrusion technology in our self-operated facility to help brands achieve the perfect balance between protection and cost-efficiency. What is 3-Layer Co-Extrusion? Unlike standard mono-layer films, co-extrusion allows us to “sandwich” three different layers of specialized polymer resins into a single high-performance film. Each layer serves a specific engineering purpose: The Outer Layer: Optimized for high-fidelity branding, smooth printing surfaces, and weather resistance. The Core Layer: Engineered for maximum puncture resistance and tensile strength to prevent parcel bursts during transit. The Inner Layer: Formulated with specialized additives to provide high opacity (security) and superior adhesive bonding for the seal. Reducing Logistics Costs through “Material Down-gauging” The primary financial benefit of our co-extrusion technology is Material Down-gauging. By utilizing stronger, multi-layered films, we can produce mailers that are thinner than traditional bags but offer significantly higher tear strength. Lower Freight Costs: Thinner films reduce the overall dimensional weight of your parcels, which is critical for lowering cross-border air freight expenses. Reduced Waste: Higher puncture resistance means a lower damage rate, saving your brand the massive costs associated with returns and customer dissatisfaction. The PAC·ZELON Advantage As both a manufacturer and an integrated partner, we don’t just sell you a standard thickness. Our technical team analyzes your product’s weight and shipping route to engineer a bespoke film formulation. By choosing our co-extruded solutions, you are investing in a packaging chain that minimizes material waste while maximizing logistics performance.
