Product Overview:

The Polyethylene-Based Empty Medicated Patch is a advanced transdermal delivery system designed for pharmaceutical, nutraceutical, and wellness applications. Constructed from medical-grade polyethylene (PE) film, this patch offers superior barrier properties, controlled release characteristics, and excellent dimensional stability. It serves as an ideal carrier for topical medications, pain relief formulations, and active pharmaceutical ingredients requiring controlled absorption rates.

Material Composition and Specifications:

Base Material	Medical-grade polyethylene film, 30μm to 100μm thickness options
Backing Layer	Transparent or opaque PE film with moisture barrier properties
Release Liner	Fluoropolymer-coated PET film for controlled release
Adhesive Layer	Medical-grade silicone or acrylic adhesive (pressure-sensitive)
Size Options	Standard 5cm×7cm, 7cm×10cm, 10cm×14cm, or custom dimensions
Drug Capacity	0.2ml to 5ml depending on patch size and formulation viscosity
Permeability	Controlled moisture vapor transmission rate (MVTR) options available
Packaging	Heat-sealed aluminum foil pouches with desiccant for moisture protection

Key Features and Benefits:

Chemical Resistance: Excellent compatibility with wide range of active ingredients
Controlled Release: Matrix structure allows predictable drug release kinetics
Moisture Barrier: Protects hygroscopic formulations from environmental degradation
Optical Clarity: Transparent option enables visual inspection of drug layer
Flexibility: Conforms to body contours without cracking or delamination
Thermal Stability: Maintains integrity across temperature variations (-20°C to 60°C)
Non-Reactive: Minimal interaction with sensitive pharmaceutical compounds
Skin Compatibility: Hypoallergenic materials suitable for sensitive skin types
