Plastic film refers to thin, flexible sheets of synthetic polymer used in medical simulation to create transparent barriers, anatomical membranes, window panels, and smooth tissue surfaces. Available in various thicknesses and polymer types (polyethylene, PVC, polypropylene), plastic films provide visual access while simulating membrane-like tissue layers. This page covers rigid/semi-rigid plastic films and sheets. For cling film/food wrap, see Plastic Wrap.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes | |
|---|---|---|---|---|---|
| Peritoneum/Serosa | Yes | Partial | Peritoneal models, abdominal cavity visualization | Recipe: Clear polyethylene film (0.1–0.2 mm). Provides transparent membrane layer that allows visualization of underlying anatomy while maintaining minimal handling stress. | |
| Peritoneum and Serosa | Partial | No | Medeiros | OC model only. Yellow cellophane (plastic film) layered with Latex (female condom) to simulate peritoneal sac covering herniated viscera.[1] | |
| Soft Tissue Envelope | Partial | Partial | Tibial Shaft Transverse Fracture Simulator, Humeral Fracture Fixation Simulator | Clear cellophane (redirects to Plastic Film) wrapped around 3D printed bone fragments to simulate the soft tissue envelope on the orthopaedic Tibial Shaft and Humeral Fracture Fixation external-fixation simulators (Intuitive Foundation / Tibial Fracture Fixation Team). Permits visual inspection for learner self-assessment of Schanz screw trajectory. | |
| Cornea | Yes | Partial | Ophthalmologic training, anterior chamber models | Recipe: Clear rigid film (0.3–0.5 mm), heat-formed to curve. Curved transparent surface replicates corneal refraction properties needed for instrument navigation training without visual obstruction. | |
| Pleura | Partial | Partial | Thoracic cavity models, lung simulation | Recipe: Thin polyethylene sheet (0.05–0.1 mm). Creates sliding interface between lung model and cavity wall, allowing demonstration of pleural mechanics and tissue plane separation without excessive resistance. | |
| Fascial window | Yes | — | Fascial dissection models, visualization training | Recipe: Transparent PVC sheet, cut to size. Provides transparent window in opaque fascia layers to allow observation of underlying structures during dissection practice. | |

Troubleshooting
- Load-bearing applications — Most plastic films tear under tension. Use: Silicone sheet or vinyl for strength.
- Suturing practice — Film tears around needle holes; cannot hold sutures. Use: Felt or silicone for suturable membranes.
- Heat-contact procedures — Most plastic films melt or warp with electrosurgery. Verify: Material melting point before use with thermal devices.
- Elastic tissue simulation — Standard plastic film has minimal stretch. Use: Latex or rubber for elastic membranes.
Alternatives
| Alternative | Best For | Trade-offs |
|---|---|---|
| Plastic Wrap (cling film) | Self-adhering membrane; serosal surfaces | Very thin; tears easily; adhesive may be unwanted |
| Silicone Sheet | Durable transparent membrane; suturable | Higher cost; requires sourcing specific thickness |
| Vinyl Sheet | Semi-rigid transparent panels | Less flexible; may crack at folds |
Used In Simulators
| Simulator | Purpose | Notes |
|---|---|---|
| Medeiros Abdominal Wall Defect Simulator | Yellow cellophane layered with latex (female condom) simulates peritoneal sac on omphalocele model.[1] | |
| Tibial Shaft Transverse Fracture Simulator | Clear cellophane wrapped around 3D printed proximal and distal tibial bone fragments simulates the soft tissue envelope and permits visual inspection for self-assessment of Schanz screw placement. | |
| Humeral Fracture Fixation Simulator | Clear cellophane wrapped around 3D printed humeral bone fragments simulates the soft tissue envelope and permits visual inspection for learner self-assessment of Schanz screw trajectory and fracture alignment during external fixation. |

Clinical Context for Simulation
[edit source]Plastic film provides visualization windows and membrane layers in anatomical models. Its transparency allows learners to see underlying structures while still requiring them to work through defined tissue planes. The material's availability in various thicknesses allows matching to specific membrane properties.
Processing & Preparation
[edit source]Select thickness based on application — thinner (0.05–0.1 mm) for membrane simulation, thicker (0.2–0.5 mm) for structural windows. Cut with scissors or craft knife; cut edges remain smooth (no fraying like fabric). Attach to model frames using tape, staples, or adhesive; heat-sealing possible for some polymer types. Some films can be heat-formed to curved shapes using hair dryer or heat gun.
Safety Considerations
[edit source]- Suffocation hazard — Keep film away from face; never use near airways in simulation.
- Static electricity — Film may cling to instruments; can be reduced with antistatic spray.
- Heat sensitivity — Most films melt at low temperatures; verify compatibility with thermal devices.
- Sharp edges — Cut edges may be sharp on rigid films; handle carefully.
