Automatic shrink wrapping machinery is normally selected when hand packing or a chamber sealer cannot keep pace with product flow. The right route depends on product size, pack grouping, film type, infeed stability and the amount of integration needed with upstream and downstream equipment.
When automatic machinery is the better route
Automatic machinery suits repeat products, consistent pack dimensions and output targets where manual sealing creates a bottleneck. Bottle bundles, carton packs, printed matter, trays and retail packs can often be handled through a dedicated sealer and heat tunnel arrangement.
Main machine routes
Use sleeve sealers for multipacks and trayless bundles, L-sealers or side sealers for clear presentation packs, and heat tunnels for controlled shrink after the seal. Sleeve applicators are used when the requirement is label shrinking, neck bands or bottle capsule shrinking rather than outer transit wrapping.
What Lancing needs to quote
Useful details include product dimensions, pack weight, desired finish, film material, packs per minute, infeed height, site power, compressed air availability and the amount of factory footprint available for conveyors and discharge.

Frequently asked questions
What is an automatic shrink wrapping machine?
It is a packaging machine route that automatically presents, seals and shrinks film around products using a sealer, tunnel and conveyor handling rather than relying on manual chamber operation.
Which film is used for automatic shrink wrapping?
PE, POF and PVC can be used depending on pack format, finish and production requirement. Lancing can confirm the practical film route around the product and machine configuration.
Can automatic shrink wrapping machines be integrated into an existing line?
Yes. Infeed, spacing, conveyor height, coding, labelling and downstream accumulation can be considered during specification.
