PA/PE Composite Film: High-Performance Packaging Solution


Product Overview

PA/PE composite film is a multi-layer co-extruded or laminated film, combining the superior properties of Polyamide (PA, nylon) and Polyethylene (PE). As a flagship product in flexible packaging, it integrates PA’s excellent tensile strength, puncture resistance, and barrier performance with PE’s heat-sealability, toughness, and cost-effectiveness. Widely used in food, electronics, medical, and industrial packaging, this film provides reliable protection for products while extending shelf life, making it a preferred choice for international trade and high-end packaging needs.

Core Properties & Technical Advantages

Property CategoryKey FeaturesTechnical Parameters (Typical Values)
Barrier PerformanceExcellent oxygen, moisture, and aroma barrier; prevents product oxidation, moisture absorption, and flavor loss.Oxygen transmission rate (OTR): ≤5 cm³/(m²·24h·atm) (23℃, 0% RH); Water vapor transmission rate (WVTR): ≤3 g/(m²·24h) (38℃, 90% RH)
Mechanical StrengthHigh tensile strength, tear resistance, and puncture resistance; withstands transportation and handling impacts.Tensile strength: MD ≥ 150 MPa, TD ≥ 120 MPa; Elongation at break: MD ≥ 300%, TD ≥ 250%; Puncture resistance: ≥8 N
Processing AdaptabilityGood heat-sealability (PE layer as heat-seal side); compatible with printing, lamination, and bag-making processes.Heat-seal temperature: 120-160℃; Seal strength: ≥3 N/15mm
Safety & DurabilityFood-grade materials (compliant with FDA, EU 10/2011 standards); acid, alkali, and oil resistance; no toxic substances released.Service temperature: -40℃ to 120℃ (short-term heat resistance)
