LDPE – Full Cleaning Validation Description LDPE Cleaning Validation Coupons are designed to represent LDPE (Low Density Polyethylene) Cleaning Validation Coupons model flexible polyolefin surfaces used in liners, bags and pharma packaging. LDPE provides good chemical resistance, low extractables and moderate cleanability. Ideal for GMP swab and rinse recovery studies on soft plastic MoCs.. They are used in pharmaceutical, bioprocess, and GMP-regulated systems to assess residue recovery, detergent compatibility, and cleanability of equipment surfaces made from LDPE. These coupons support RF% studies, swab and rinse recovery validation, and regulatory documentation for cleaning procedures involving this material of construction. ✔ KEY PURPOSES • Establish residue recovery factors (RF%) for LDPE surfaces • Validate swab and rinse recovery in GMP cleaning procedures • Assess chemical compatibility with detergents and disinfectants • Provide FDA/EMA/PIC/S-compliant cleaning validation documentation • Ensure robust justification for equipment made from LDPE ✔ MATERIAL CHARACTERISTICS • Material behaves as described in its summary: LDPE (Low Density Polyethylene) Cleaning Validation Coupons model flexible polyolefin surfaces used in liners, bags and pharma packaging. LDPE provides good chemical resistance, low extractables and moderate cleanability. Ideal for GMP swab and rinse recovery studies on soft plastic MoCs. • Suitable for RF% reproducibility • Stable under standard cleaning conditions ✔ FORMATS • 50×50 mm or 75×75 mm validation plates • 2–5 mm construction depending on material
