Plastic film refers to thin, flexible sheets used in medical simulation to create transparent barriers, anatomical membranes, window panels, and smooth tissue surfaces. Most are synthetic polymers (polyethylene, PVC, polypropylene), available in various thicknesses, and they provide visual access while simulating membrane-like tissue layers. Ordinary plastic cling wrap from a kitchen roll belongs here too, and several of the builds below call for it by that name. Cellophane belongs here too and can be used in the same roles — several of the builds below name it specifically — even though it is regenerated cellulose rather than a plastic.
Tissues
| Tissue | Visual | Tactile | Simulator | Notes |
|---|---|---|---|---|
| Peritoneum and Serosa | Medeiros, Appendectomy Simulator, Open Appendectomy Simulator (Matthews), Laparoscopic Inguinal Hernia Repair Simulator (Kurashima), Trocar Placement Simulator, Laparoscopic Ectopic Pregnancy Simulator, Laparoscopic Inguinal Hernia Repair Simulator (Hanssen) | Yellow cellophane is used as the peritoneal sac covering the herniated viscera on the omphalocele model (Abdominal Wall Defect, Medeiros).[1] Two layers of food-grade plastic wrap are used both as the innermost peritoneal lining of the abdominal wall (Appendectomy).[2] and for the mesosalpinx in(Laparoscopic Ectopic Pregnancy, ALL-SAFE).[3] Plastic wrap is used as both the innermost sheet of the eight-layer abdominal-wall analogue (Open Appendectomy, Matthews).[4] and as the innermost peritoneal layer of the five-layer abdominal wall, (Trocar Placement, ALL-SAFE).[5] Press'n Seal plastic wrap is laid over a stacked insert to form the peritoneum — it clings to the sponge beneath, so peeling it off feels as stubborn as a real preperitoneal dissection (Laparoscopic Inguinal Hernia, Kurashima).[6] Ioban 6648 (3M) is used as a self-adhesive plastic field laid over the assembled model to represent the peritoneum (Laparoscopic Inguinal Hernia, Hanssen).[7] |
||
| Periosteum | Tibial Shaft Transverse Fracture Simulator | Clear cellophane is wrapped around the 3D-printed tibial fracture fragments as the overlying periosteum, keeping a displaced fracture loosely apposed; its transparency lets the learner inspect post-fixation alignment and confirm no Schanz screw perforated the far cortex.[8] | ||
| Skin | Carter Multipurpose Thoracic Simulator | Ioban 2 antimicrobial drape (3M) — a transparent iodophor film is used for wrapping the chest-wall module as sealant and outermost traversable layer for needle entry and chest-tube placement.[9] | ||
| Fascia | - | - | Appendectomy Simulator, Open Appendectomy Simulator (Matthews) | Food-grade plastic wrap is used as a separator layer of the abdominal wall (Appendectomy); that build guide calls it only “plastic wrap” and does not name Scarpa’s fascia anywhere.[2] The Matthews build specifies plastic film between the superficial and deep fat planes, listed as Scarpa's fascia and distinct from the plastic film the same build uses for the peritoneum (Open Appendectomy, Matthews).[4] |
| Connective Tissue | - | - | Humeral Fracture Fixation Simulator, Peripheral Intravenous Catheterization Trainer | Clear cellophane is used for the soft-tissue envelope wrapped around the distracted humeral fragments — transparent so the learner can check fracture alignment and that no Schanz screw perforated the far cortex. Multipurpose sealing wrap (Glad Press'n Seal or equivalent) is used as a self-adhering subcutaneous layer wrapped over the simulated vein to give a palpable tissue plane.[10][11] |
| Pleura | - | - | Chest Tube Insertion Simulator (Man-O-War) | Cellophane (plastic film) is rolled around the bucket with gaffer tape laid over the intercostal spaces — the composite parietal-pleura layer the learner punctures.[12] |
| Hernia sac and preperitoneal adhesions | Laparoscopic Inguinal Hernia Repair Simulator (Kurashima) | Press'n Seal plastic wrap is placed at the base of the hernia defect, its adhesions made with spray glue and adherent putty. Careless dissection tears the thin film just as it would tear real peritoneum, so the trainee must work meticulously (Laparoscopic Inguinal Hernia, Kurashima).[6] | ||
| Cricothyroid membrane | - | - | Cricothyrotomy Simulator (Kei) | Tegaderm is indicated not built with. Kei forms the cuttable cricothyroid-membrane proxy from 3M Microfoam surgical tape over the printed model, and offers a film alternative only as a fallback: “if Microfoam tape is not available, duct tape, gaffer’s tape or 3M Tegaderm can be used as a substitute”.[13] |
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 |
