Flow Wrapping Machines

Start with product geometry and feeding

Send the smallest and largest products, their orientation and how they arrive at the wrapper. We use those inputs to review the infeed, pack format and forming boxes before comparing output.

• Product or tray L × W × H in mm, with photos
• Fragility, stickiness and orientation on the infeed
• Hand loading or upstream conveyor transfer, with a short video
• Number and position of items in each finished pack

Infeed options

Products need to reach the wrapper in a repeatable position and spacing. An operator can load an automatic wrapper by hand; an automatic feeder needs to match the product and the upstream process.

• Hand loading: an operator places products on the automatic wrapper’s infeed
• Automatic transfer from a production conveyor, with alignment and spacing
• Rotary disc feeding for small candies, shown in a confectionery configuration
• Tray feeding for produce and frozen dumplings
• Multi-component feeding for kits such as cutlery sets or noodles with seasoning sachets

Models and configuration ranges

Compare the LV-250B/D, LV-250X and application-specific configurations by their own pack ranges and infeed arrangements. We specify the required output, film and tooling for the selected product and format.

Each row defines a separate configuration. The 350 mm film width applies to the high-speed candy configuration. Select the applicable bag-length range (45–190 or 90–330 mm) and product-height limit (up to 40 or 70 mm) together with the forming box and infeed. We confirm the combined pack envelope and good output with your product and film; the tabulated speeds are configuration baselines.

End-seal jaw motion is a separate configuration question from film layout and feeding. Rotary jaws rotate through sealing contact; box-motion jaws close and follow the film during contact. The box motion vs rotary end seal comparison explains these generic motions and the film, clearance and trial evidence to review; bring the required jaw motion into the configuration review before selecting a machine.

What is confirmed for your project

The ranges above describe the machine, not your pack. Output in good packs per minute, the film width and the forming boxes needed for each product size are stated in the quotation for your product and film.

Products a flow wrapper can pack

A flow wrapper packs one product, or a fixed group or kit, per pack, as long as each pack can be fed lying down at a steady pitch. The configurations in this family cover three product groups.

Food

Chocolate and energy bars, biscuits and wafers, candy and lollipops, bread, mooncakes, instant noodles, ice lollies, honey spoons, fresh fruit and vegetables, and frozen dumplings on trays. For heat-sensitive products, include the film and sealing requirements in the configuration review.

For individually wrapped sweets and bars, the candy and chocolate flow-wrapping selection guide connects the published application references to product presentation, film and sample-evaluation inputs.

Household and personal care

Kitchen sponges, disposable toothbrushes and slippers. The kitchen sponge configuration also lists soap, paper towels and wet wipes, disposable masks, razors, scouring pads, cotton pads, dishcloths and bath sponges among its applications.

Hygiene products and disposables

Sanitary napkins on an LV-250B/D configuration, and single-portion disposable cutlery kits that combine a knife, fork, spoon, napkin and condiment sachets in one pack.

Single items or several items per pack

Wrapping single items one by one is the usual case. Several items in one pack, such as a cutlery kit or noodles with seasoning sachets, need a feeding arrangement for each component, so list every component and its position in the pack.

Film, seal tooling and pack width

For praline projects, use the cold-seal flow wrap or tray-and-carton guide to prepare your product, film and pack review.

Send the film supplier’s specification and a finished pack sample if available. Film structure, sealing method and product cross-section must be reviewed together.

Use the flow wrap film COF and jaw temperature window guide to match film Coefficient of Friction, Seal Initiation Temperature, hot tack, and heat-seal or cold-seal structures to fin-wheel traction and crimper dwell.

Film material

Send the film structure and sealing layer, thickness, reel width and diameter, and printed registration-mark details so we can match film handling and seal tooling to the pack. Confirm sealing settings with the selected film and pack; do not transfer settings from a different product.

Heat seal or cold seal

Heat-seal film uses heat at the sealing surfaces. Cold-seal film uses a coating that bonds under pressure and can be considered for heat-sensitive products. The film and tooling must match: bring cold-seal requirements into the selected configuration’s tooling review before ordering film.

Film width

Film width follows the pack cross-section: the film wraps the product's width and height and leaves enough for the fin seal. The maximum film width of the machine limits the largest pack: 250 mm on standard LV-250B/D and LV-250X builds, 350 mm on the wide-web candy configuration, and 50–120 mm on the disc-feeding candy wrapper. We set the exact reel width for your pack together with the forming box.

• Measure product width and height, including the tray where used.
• Allow film for the longitudinal fin seal.
• Confirm actual reel width and forming box together for your product cross-section.

• Heat-seal or cold-seal film, thickness and reel specification
• End seal pattern and any easy-open feature
• Coding position and code content
• Gas flushing, if the product requires it

Line integration

Flow wrappers often sit directly after production: a bakery cooling conveyor, a bar forming line or a candy line. Downstream, wrapped products may go to cartoning or case packing. Some cartoning configurations are presented as complete lines from flow wrapping to cartons for bars and pizza.

Rigid boxes that need a tight folded film finish belong to the cellophane overwrapping route rather than flow wrapping.

What to confirm with LINEVO

Ask for a proposal that names the wrapper, infeed or feeding module, forming boxes and change parts for each product size. Coding, gas flushing and other requested options should be identified as included, optional or requiring review.

If product handling or sealing needs evaluation, discuss a sample test before shipping material. Agree the product, film, sample quantity and record required with the team. The quotation should also state the pre-shipment checks and acceptance criteria.

Confirm installation, commissioning, training and spare-parts scope for your destination. Supply the voltage, phase and frequency at the machine location, and ask which manuals, drawings and wear parts are included.

From enquiry to an agreed configuration

Send the inputs in the “What to send us” table through WhatsApp or use the project brief checklist. Mark undecided items as open so we can identify what is needed for the proposal.

Review the model, feeding arrangement, formats, options and agreed checks in the quotation before placing the order. For product or film behavior that needs evaluation, start with sample-testing preparation.

Questions buyers ask about flow wrappers

Can one wrapper run several product sizes?

Pack length changes with the cut length. A significant change in width or height may need another forming box and infeed adjustment, which should be listed in the quotation; see how a flow wrapper forms the pack for why the forming box follows the cross-section.

Should I choose hand loading or an automatic infeed?

Hand loading lets an operator place products on an automatic wrapper’s infeed. An automatic feeder must match how products leave the upstream process. Send a video showing orientation and spacing so the proposal can identify the feeding scope.

Can a flow wrapper pack bar soap?

The kitchen sponge configuration lists soap among its applications. If the soap needs a carton, the cartoning family lists a bar soap cartoner; a tight folded film finish on a rigid box belongs to the overwrapping family.

What is the difference between flow wrapping and overwrapping?

A flow wrapper makes a pillow pack with fin and end seals. An overwrapper folds film tightly around a rigid box, like the film on a perfume or tea box.

How does a flow wrap machine work?

Products enter a forming section, where reel film folds around them. Longitudinal sealing closes the film tube, and end sealing and cutting separate the packs. The flow wrapping guide explains the sequence; jaw motion and film position are configuration-specific.

What is the price of a flow wrapping machine?

We prepare the quotation from your product and required output. Price depends on the wrapper model, the infeed or feeding module, the forming boxes and change parts for each size, and options such as coding or gas flushing.

Engineering basis and sources

Updated 21 October 2026. Each linked LINEVO configuration defines the infeed and specification baseline for its row. We confirm the combined bag-length, height and film-width envelope with the forming box for your product, including the 350 mm film width on the high-speed candy configuration.

Generic film-path and sealing descriptions were checked against Syntegon’s inverted film explanation and sealing and cutting overview. These explain process principles; available LINEVO layouts, tooling and options are confirmed for the selected configuration.
