Thin gauge thermoforming powers medical device packaging, food trays, ESD electronics nests, and industrial blisters. At Blue Ridge Thermoforming, inline and roll-fed equipment supports high-cavity production with the quality systems OEM customers expect.
Thin gauge sheet typically runs from 0.010" to 0.060" depending on part depth, seal flange stiffness, and nest retention requirements. Shallower trays and blisters use thinner sheet; deeper medical cavities or ESD nests may need thicker gauge to avoid thinning and webbing. Material choice — PETG, RPET, HIPS, PVC, or specialty ESD films — affects clarity, sealability, and downstream sterilization compatibility.
Best for very high volume, repeating cavities, and automated downstream packaging. Lowest piece cost at scale.
Flexible for larger parts, lower volumes, or frequent changeovers. Common for custom clamshells and specialty trays.
Clear PETG medical trays require uniform heat across the sheet, controlled plug assist on deep cavities, and a flat seal flange wide enough for Tyvek or film lidding. Plug geometry and draw limits are validated in DFM before cavity machining. Uneven flange width or chill marks at the seal surface cause downstream sealing failures — caught in first-article approval, not on the packaging line.
Inline thermoforming integrates forming with in-line punching, stacking, or downstream packaging on roll-fed equipment. High cavity count and fast changeover drive the economics on medical and industrial programs. Cut-sheet thin gauge remains the right choice for larger clamshells, lower volumes, or frequent SKU changeovers where roll-fed setup does not pay back.
ISO 9001 process control and cavity-level inspection protect high-volume packaging programs. Seal flange flatness, cavity dimensions, and material traceability are verified before production ramps — not discovered on the packaging line.
We run thin gauge programs for medical, industrial, and electronics customers from Greenville, SC.
Thin gauge thermoforming produces packaging and trays — blisters, clamshells, medical device trays, ESD nests, and food packaging from thin plastic sheet.
Inline thermoforming integrates forming with in-line trimming, stacking, or packaging steps on roll-fed equipment for high-throughput production.
