Foil liner bonds
A compatible liner inside a cap may be bonded to the container mouth using an assessed induction process. Send the bottle, closure and liner together so neck contact and material compatibility can be considered as one assembly.

Bottle sealing
A clearer route to the right equipment.
A bottle seal may provide a liner bond, a closed mouth or a visible tamper feature. These are different functions and should not be treated as interchangeable. Start with the bottle material, neck finish, closure and contents. Then establish what the finished seal must achieve and how that requirement will be checked.

bottle sealing machine: where to start.
Explore the production situations that shape the specification. These examples describe requirements to discuss, rather than confirmed machine configurations.
Direct mouth membranes
A membrane or lid applied at the mouth requires a suitable container and joining process. Provide the pack construction, opening requirement and sealing surface details rather than assuming all bottle-mouth materials can use the same equipment.
Cap and neck opening features
An external sleeve can provide a visible opening feature around the cap and neck. Define this function separately from leakage or a bonded mouth seal, and review the intended bottle and closure geometry.
Compare the approach
Start with the way you work.
Use these routes to frame the discussion. Lancing will confirm the proposed machine, handling method and scope against your product and packaging.
OPTION / 01
Induction liner sealing
A compatible foil liner inside the cap is heated by an induction field to form a bond to the container. Bottle, liner and cap specifications need to be assessed together.
Consider whenSuitable capped bottles requiring a compatible bonded mouth liner.
OPTION / 02
Direct mouth sealing
A lid or membrane is applied at the bottle opening using a compatible process. Container support, access to the mouth and the seal material determine the machinery concept.
Consider whenPacks designed around a directly applied membrane or lid.
OPTION / 03
Tamper-evident sleeving
A sleeve around the cap and neck provides an opening feature when correctly specified. It serves a different purpose from a bonded mouth seal and should be reviewed accordingly.
Consider whenBottle packs requiring a visible cap-opening feature.
Specify what matters
Small details.
Better decisions.
Start with the constraints that affect your application. Our selection guide helps you organise a useful machinery brief.
Read the selection guide - 01
Define the seal function
Explain whether the requirement concerns leakage, a bonded liner, an over-cap sleeve or visible opening evidence.
- 02
Treat the components as a set
Send bottle, cap and liner together, including drawings where available.
- 03
Plan inspection and handling
Describe the proposed quality checks and how packs are handled after sealing.
The application process
Define it. Review it.
Agree the scope.
A practical starting point for your enquiry, with the actual specification confirmed before an equipment decision.
Set the pack requirement
Describe the product, bottle, closure and seal function. Include representative samples of every component in the finished assembly.
Review the whole sequence
Consider filling cleanliness, cap application, sealing and pack discharge together, including interfaces with existing machinery.
Confirm an acceptance method
Agree the evidence needed for the chosen seal function and identify the checks performed during production and format changes.
Before you enquire
Your questions,
considered.
Practical answers to help you prepare a more useful discussion.
Does a tamper sleeve stop leaks?
Its principal purpose is different from a mouth seal. State the leakage and opening-evidence requirements separately and assess the finished pack against both.
Can induction sealing work on any bottle?
No universal compatibility should be assumed. The container material, neck, cap and liner must form a suitable assembly and be confirmed for the proposed equipment.
Does cap tightening affect the sealing process?
It can affect liner contact and pack consistency. Include the closure-application method and the cap supplier information when reviewing a sealing proposal.
What should I send for an enquiry?
Send empty bottles, caps and liners with the product description, required speed and current seal concern. Photos are useful, but component samples reveal details that photographs may miss.
