The field guides

Make the next decision clearer.

Four practical guides, from sealing choices and troubleshooting to line planning and inspection. New field notes added 15 October 2026.

NOTE / 03

Line planning · 6 min read · 15 Oct 2026

Plan the filling line around the finished pack.

Connect product behaviour, closing sequence and machine interfaces. Prepare a sample brief that makes a complete-line trial useful.

NOTE / 04

Inspection · 6 min read · 15 Oct 2026

Choose the inspection by the defect you need to find.

Weight, metal, visible defects or thermal anomalies? Compare what each method can show and how to test it on your own packs.

Read the inspection guide

NOTE / 01

Selection · 5 min read

Choose the process before the machine.

Direct heat sealing, cap-liner induction, or tray sealing? A practical way to narrow the route and prepare your samples.

NOTE / 02

Troubleshooting · 5 min read

When the seal changes, start with the evidence.

Separate material, positioning and process questions. Use a simple comparison record to make the next trial useful.

Before the enquiry

Four things worth gathering.

A clear sample brief makes it easier to discuss fit, tooling and the trial you actually need.

01 / THE PACK

Container details

Bring real samples, opening dimensions, rim photos and the container material specification.

02 / THE MATERIAL

Film, liner or lid

Include the supplier reference and material structure. A photo of the foil alone is not a specification.

03 / THE RESULT

Acceptance criteria

Describe the seal appearance, opening behaviour and inspection method your team needs to confirm.

04 / THE LINE

Production context

State your output target, loading method, format changes and the equipment before and after sealing.

The equipment directory

Find your place in the line.

Browse 106 products across 14 Sealerweb categories. Compare machine types here, then open the supplier page for configuration and sample review.
