Specifying nominal gauge without considering corner thinning
Packaging format
Forming Webs
Forming webs deserve direct technical attention. Draw depth, cavity geometry, product shape, gauge distribution, forming temperature and the lidding interface all affect performance. Packaging HQ coordinates the web with the application and equipment rather than treating it as generic roll stock.
PROJECT FOCUSForming performance is controlled by geometry, temperature and material distribution.
Web dimensions, film layers, print, seals, and roll requirements are developed around the application and filling line.
What the specification must resolve
What to confirm before production.
The bottom web must draw into the cavity without unacceptable thinning, distortion or stress. Draw depth, corner radius, plug assist, forming temperature, cycle speed and the top-web seal interface should be reviewed together.
Key considerations
- Draw depth and cavity geometry
- Gauge and corner-thinning risk
- Forming temperature and cycle speed
- Seal compatibility with the top web
Common applications
- Portioned foods
- Protein and cheese
- Medical and consumer products
- Thermoformed flexible packs
Where projects go off track
Confirm these details early.
Changing the forming web without confirming lidding compatibility
Evaluating appearance without checking cavity and seal performance
01Product, fill and performance target
02Filling line, dimensions and material inputs
03Samples, trials, graphics and final approval
A common question
What should a forming-web review include?
Cavity drawings, draw depth, product shape, current web and gauge, forming conditions, cycle speed, top web, seal settings and examples of any thinning, tearing or release issue.
