SPECIMEN RETRIEVAL BAG
- Puncture & tear resistance: Withstands contact with bone edges, clips, staples, and serrations during pull-through.
- Elastic conformability: Drapeable, “non-crinkle” handling for easy specimen capture and reduced snagging.
- Clarity & visibility: High transparency for visual confirmation; optional matte/low-glare to reduce reflections.
- Seamability: Excellent heat, ultrasonic, and RF weld response for durable seams and rims (low pinhole risk).
- Chemical & fluid resistance: Stable against blood, bile, saline, common disinfectants; ether-based TPU resists hydrolysis.
- Low-temperature toughness: Remains flexible in cold OR environments; low stress-whitening on tight folds.
WOUND DRESSING
- Moisture management: Tunable MVTR/RET to maintain a moist healing environment while avoiding maceration.
- Fluid & pathogen barrier: Dense, continuous film resists liquid penetration
- High conformability: Elastic, drapeable, and crease-resistant—stays sealed on joints and contours, extending wear time.
- Soft & quiet: Low “crinkle noise,” smooth hand feel, better patient comfort.
- Optical clarity: High transparency for site monitoring; matte or tinted/opaque options available.
- Tear / puncture resistance: Stronger at equal thickness vs. many commodity films.
- Process-friendly: Compatible with heat sealing, ultrasonic, and RF welding; bonds well with acrylic/PU/silicone medical adhesives.
- Biocompatibility
- Low-temperature flexibility: Remains supple in cold chain and winter conditions.
MEDICAL TAPE
- Soft, elastic, highly conformable
- Strong & puncture/tear resistant.
- Excellent liquid barrier
- high transparency
- Durable in moisture & body fluids.
- Sterilization-compatible.
- Printable/brandable
SURGICAL DRAPE
- Primary Barrier Lamination Film
Laminated to SMS/SMMS nonwovens to create a continuous fluid barrier and raise hydrostatic head.
Thickness: 50–80 μm. Material: Ether-based TPU (hydrolysis resistance) or aliphatic TPU (high clarity). - Fenestration Window Film
Transparent film around the incision area for visibility and positioning while maintaining liquid tightness.
Thickness: 60–100 μm. Surface: Gloss/low-friction; corona-treatable for printing/marking. - Reinforcement Patch Film
TPU film applied around the cutout to boost tear and puncture resistance.
Thickness: 70–120 μm. Shape: Rounded rectangle or ring. - Collection Pouch / Fluid Channel Film
Transparent TPU film heat-sealed to form pouches or flow guides; bend-resistant and leak-tight.
Thickness: 80–120 μm. Build: Dual sealing lines; drop and flex-cycle validated. - Anti-Slip / Positioning Overlay Film
Matte or micro-textured TPU film zones where instruments rest to reduce slippage.
Thickness: 60–100 μm. Surface: Matte or light emboss; anti-blocking preferred.
Overview
TPU (Thermoplastic Polyurethane) film is widely used in the medical industry due to its excellent biocompatibility, flexibility, durability, and chemical resistance. TPU film provides safe, skin-friendly, and high-performance solutions for various medical devices and healthcare products. It can be used directly or laminated with other substrates such as PE, PP, PET, or nonwoven fabrics, meeting the strict hygiene, sterilization, and regulatory requirements of the medical sector.
