Sleeve sealing machinery for bottles, bundles, trays and cartons

Use this page to match the sleeve sealing route to the product format, film material, pack count and required final presentation.

Pack formats

Common sleeve sealing applications

Bottled water and drinks

Multipacks of water, soft drinks, juices and similar beverage products where a secure shrink-wrapped bundle is needed.

Food and household products

Grouped jars, tins, cartons, tubs or bottles that need transit protection and a tidy shelf-ready format.

Contract packing

Flexible multipack and changeover-heavy work where the machine must handle multiple products and pack counts.

Trayless multipacks

Bundled packs where film strength, shrink quality and product stability must be checked carefully.

Cartons and boxes

Grouped cartons or rectangular products requiring straight presentation through the sealing and tunnel stages.

Line upgrades

Existing filling, capping or labelling lines that need an end-of-line sleeve sealing stage added.

Specification route

The correct sleeve sealer starts with the finished pack

Before comparing machines, define how the product should leave the line: pack count, bundle orientation, film thickness, barcode or label visibility, pack stability, heat sensitivity and palletising or downstream handling.

From there, Lancing UK can review the sealing jaw size, film roll width, tunnel aperture, tunnel conveyor speed, infeed conveyor length and operator access around the line.

Application engineering

Different bundle formats place different demands on the sleeve wrapping line

Bottles, cans, trays, cartons and contract-packed bundles can all use a sleeve wrap, but they do not behave the same through collation, sealing and the shrink tunnel. The application review must consider how the products support one another, where the film can grip and whether the finished pack will remain stable during handling.

Bottles and cans

Round products can move during transfer and may need controlled guides, stable row formation and consistent spacing. Filled weight, base shape, cap or closure height and the chosen pack count influence collation and tunnel transport.

Food trays and cases

Tray flanges, corners and projecting edges can concentrate load in the film. Confirm whether the tray is sufficiently rigid, whether a pad is needed and whether heat could affect the tray, lidding film, label or product.

Contract-packed bundles

Frequent product and pack-count changes increase the importance of accessible guides, repeatable recipes or setting records, film change control and a clear acceptance sample for each approved format.

Tray-supported and trayless packs

A tray or pad can add base support, protect product edges and improve handling, but it also changes pack height, heat response and film contact. A trayless bundle uses less secondary material but relies more heavily on product geometry, film strength and shrink control. Neither format should be selected from appearance alone; trial the intended lifting, transfer and stacking method after the pack has cooled.

Application variables to record

Pack information for an application assessment
ProductDimensions, filled weight, surface finish, temperature, stability and any heat-sensitive features.
BundleCount, row pattern, orientation, tray or pad, required openings and final dimensions.
FilmMaterial, grade, thickness, roll width, shrink direction and approved supplier specification where available.
HandlingInfeed condition, operator loading, conveyor transfers, cooling, accumulation, lifting, stacking and pallet pattern.
AcceptanceSeal continuity, shrink appearance, product condition, bundle integrity and repeatable performance at the agreed output.

When another route may be better

An individual product requiring a fully enclosed presentation bag may belong on an L-sealer. A printed or tamper-evident sleeve around one bottle belongs on a shrink-sleeve applicator. SleeveSealers.co.uk remains focused on grouped products, trays, cases and multipacks.

Application FAQs

Questions about products and bundle formats

Can one sleeve sealer handle bottles, cans and trays?

A machine may cover more than one format when the size range, guides, film path, tunnel and changeover arrangement are suitable. Each materially different pack should still be assessed and approved with samples.

When is a tray useful under a multipack?

A tray can improve base support, edge protection and downstream handling. Its material and geometry must tolerate the tunnel and must be included when pack dimensions and film width are calculated.

Are trayless bundles always suitable?

No. Trayless packs depend on stable product geometry, suitable film and adequate finished-bundle strength. Heavy, irregular or easily damaged products may need additional support.

Should empty bottles be used for a trial?

Only when they represent production behaviour. Filled or weight-matched samples are normally more useful because weight changes collation, conveyor transfer and film tension around the bundle.

How should a contract packer control many formats?

Keep approved samples, drawings, film specifications and recorded settings for each format. Changeover checks should verify guides, sensors, film position, seal quality, tunnel settings and the cooled finished pack.

Assess the real application

Send the product, bundle pattern and handling requirement

Lancing can review whether the pack should be tray-supported or trayless and what collation, film, tunnel and discharge arrangement needs to be trialled.

Application engineering matrix

Different products fail for different reasons during sleeve wrapping

The same machine family may handle bottles, cans, trays, cartons and cases, but the evidence required for a reliable project changes with the pack architecture and downstream handling.

Application compatibility questions

Questions buyers ask about products, bundles and heat exposure

Application suitability depends on the product, support method, film, tunnel process and the condition required after cooling and handling.

Can heat-sensitive products be sleeve wrapped?

Sometimes, but suitability must be established with the actual product, primary pack, labels, adhesives, tray or pad and the proposed tunnel process.

The trial should check product condition, container shape, seals, print, labels and any temperature-sensitive contents after the full heating, cooling and handling sequence. Tunnel settings should not be selected from film alone, and a different packaging route may be needed where acceptable exposure cannot be achieved.

Can unstable bottles be shrink wrapped without a tray?

Trayless wrapping may be possible when the bottles can be positively collated and supported through the wrapper, tunnel, cooling and discharge without losing their pattern.

Bottle base geometry, centre of gravity, surface friction, fill level, cap shape, bundle count and transfer gaps all influence stability. A clamp, guide, side-feed pusher, pad or tray may be required. Test the full line sequence rather than only holding a hand-made bundle together with film.

Can different products be combined in one sleeve-wrapped bundle?

A mixed-product bundle can be assessed when the items form a repeatable, balanced group and the film does not concentrate damaging loads on the smaller or weaker component.

Record the orientation, weight distribution, protrusions, friction and height differences. The bundle should be trialled through collation, sealing, tunnel shrink, cooling and handling. Mixed packs that change composition from cycle to cycle may need a more controlled kitting or case-packing route.

What makes an application unsuitable for trayless sleeve wrapping?

Trayless wrapping is unsuitable when the products cannot hold a controlled pattern, the film would damage or deform them, or the cooled bundle cannot meet the required lifting and transport duty.

Warning signs include narrow or uneven bases, high centres of gravity, slippery surfaces, fragile corners, large height differences and handling methods that load open film sides. A tray, pad, carton or different wrapper may provide a more reliable pack architecture.

Send production-weight samples, the intended bundle layout and the required handling route so application suitability can be tested rather than assumed.
