Heavy Gauge vs Thin Gauge Thermoforming — Shirley K’s
Heavy Gauge vs Thin Gauge Thermoforming: Key Differences
Thermoforming comes in two fundamentally different categories — heavy gauge and thin gauge. They use the same basic process but produce very different products for very different markets. Knowing which you need is the first step in finding the right thermoforming supplier.
THIN GAUGE THERMOFORMING
Thin-gauge thermoforming uses plastic sheet under approximately 0.060 inches thick. It produces high-volume, disposable or single-use products:
- Clamshell packaging
- Blister packs
- Food packaging trays (disposable)
- Yogurt cups, takeout containers
Thin-gauge thermoforming runs on high-speed roll-feed equipment producing millions of parts per year. This is NOT what Shirley K’s does.
HEAVY GAUGE THERMOFORMING
Heavy-gauge thermoforming uses thicker plastic sheet to produce rigid, durable parts designed for repeated use or long service life:
- Industrial totes and trays (food handling, material handling)
- Enclosures and covers for equipment
- OEM plastic parts (instrument housings, equipment shrouds)
- Returnable dunnage and packaging
- Custom industrial components
Heavy-gauge parts are typically CNC-trimmed for precise final dimensions. Tooling costs are lower than injection molding but higher than thin-gauge packaging.
Shirley K’s specializes in heavy-gauge thermoforming for industrial and OEM applications with in-house CNC trimming.
