Medical device packaging bag

polyethylene

Overview
PE packaging film is a simple polymeric organic compound and one of the most widely used environmentally compatible packaging materials in the medical industry. PE films for medical packaging include plain PE packaging film and non-adhesive variants such as PE cling film, PE stretch film, PE wire-protection film, PE static-dissipative film, and PE anti-static film. PE packaging improves surface protection and distributes mechanical stress evenly to reduce damage from point loads.

Structural composition
Manufactured from high-quality domestic or imported PE film; some medical bags use a paper + PET composite film lamination for additional barrier and printability.

Sterilization method
Compatible with ethylene oxide (EO) sterilization methods; suitable for terminal sterilization of packaged medical devices.

Product features

• Sterility compatibility: Materials support final sterilization of medical packaging and devices without material degradation when processed correctly.
• Shelf life stability: Acts as a reliable barrier, maintaining functional integrity over the product life cycle.
• Environmental barrier: Provides isolation from moisture, air, bacteria, oxygen and light to protect sterile contents.
• Physical protection: Offers impact and abrasion resistance and structural support; edge-sealing process reduces risk of burst or delamination during handling.
• Low-temperature performance: Maintains properties at cryogenic-capable ranges (approximately −70 to −100 °C) where specified.
• Chemical and electrical stability: Resistant to most acids and bases (except strong oxidizing acids); insoluble in common solvents at room temperature; low water uptake and effective electrical insulation.

Product model and specifications
Standard sizes available: 100×100 mm to 600×600 mm. Custom sizes and formats available on request to match sterile barrier system requirements.

Characteristics of PE packaging film

• Protective function: Lightweight protective layer delivering dust-proof, oil-resistant, moisture-proof and waterproof performance while ensuring even force distribution to prevent product damage.
• Unitization: Adhesive/retractile properties allow consolidation of items to prevent separation or movement during transport.
• Space-efficient packing: Enables compact packing to limit relative movement of components in transit.
• Cost-efficiency: PE stretch and shrink films can reduce reliance on secondary packaging (boxes, bubble wrap) for certain items, improving space and cost efficiency.

Uses of PE packaging bags

• Flat PE bags: Blown film cut and bottom-sealed for simple sterile barrier pouches.
• Blown-film bags: Often produced with closure strips for manual sealing (distinct from resealable zip closures).
• Zip-lock bags: PE film formed with zipper sliders for reusable storage; side gussets and printing options available.
• Envelope bags: Feature a flap sealed with adhesive tape; common for textiles and courier packaging.
• Tote bags: Include top perforations or reinforced strips for handling and transport.
• Top strip or film attachments: Additional components added for lifting or sealing purposes.
• Film forms: Produced by blown-extrusion as stretch or shrink film for manufacture of various PE bag types.
