Flow Packing Machine

A flow packing machine — also known as a horizontal flow wrapper or pillow packing machine — wraps individual or grouped products in a continuous tube of heat-sealable film, forming a sealed pillow pack with a longitudinal fin seal and crimped end seals.

Product Overview

The Wanttone flow packing machine wraps biscuits, cookies, crackers, cakes, and Swiss rolls at industrial speed with servo-driven precision, photo-eye registration for printed film, and multi-product collation options such as 2×2, 2×3, or 1×5 arrangements. For single-piece chocolate or biscuit products, an X-Fold fold-wrap variant delivers the classic envelope-style fold pack.

Capabilities & Applications

Key Features

  • High-Speed Pillow Wrapping

    Servo-driven film feed, forming, and sealing deliver consistent pillow packs at speeds matched to your line output, from medium bakery rates to high-volume industrial production.

  • Photo-Eye Film Registration

    Automatic print-mark tracking keeps graphics centered on every pack, essential for branded retail packaging and printed OPP or laminated films.

  • Flexible Product Collation

    Infeed systems arrange products in 1×5, 2×2, 2×3 and similar multi-piece patterns for family packs and multipacks, configured to your retail format.

  • X-Fold Fold-Wrap Variant

    For individual chocolates, small biscuits, and similar single pieces, the X-Fold variant wraps product in the traditional envelope fold style — a premium, material-efficient pack format.

  • Fast, Repeatable Changeover

    Adjustable bag formers and recipe-stored parameters (bag length, sealing temperature, speed) make switching between products and pack sizes quick and reliable.

  • Hygienic Stainless-Steel Construction

    Food-grade contact parts and an open, accessible machine bed support daily cleaning and food-safety audit compliance.

  • Wide Film Compatibility

    Runs OPP, OPP/CPP, laminated, and metallized heat-sealable films, giving you freedom in packaging material sourcing and shelf-life design.

Applications

  • The flow packing machine is the workhorse of biscuit and bakery packaging: individually wrapped cookies and crackers, biscuit multipacks, wrapped cake bars and Swiss rolls, wafer packs, and chocolate piece fold-wrapping with the X-Fold variant. It connects directly to Wanttone biscuit stackers, feeding and stacking lines, and sandwiching systems for a complete bake-to-pack solution.

A Defined Role in the Line

  1. Upstream Requirements

    Confirm the incoming material or product condition, target throughput, infeed height and available utilities.

  2. Core Machine Function

    Servo-driven film feed, forming, and sealing deliver consistent pillow packs at speeds matched to your line output, from medium bakery rates to high-volume industrial production.

  3. Downstream Integration

    Match discharge height, line speed, control signals, guarding and cleaning access with the next operation.

The Wanttone Difference

A flow wrapper performs at its best when it is designed as part of the line that feeds it — and that is exactly how Wanttone delivers. As a complete biscuit line manufacturer, we engineer the stacker, collation, and infeed together with the wrapper, so film registration, pack count, and speed hold stable at full line output instead of fighting upstream inconsistencies. Our own biscuit factory wraps its branded cookies and crackers on this class of equipment every day, so our recommendations on film choice, pack format, and line balancing come from production reality. Backed by 40+ years of equipment engineering, ISO 9001 manufacturing, turnkey line delivery, on-site commissioning, operator training, and lifetime after-sales service, your packaging investment is protected for the long term.

Frequently Asked Questions

What products can a flow packing machine wrap?

Biscuits, cookies, crackers, wafers, cakes, Swiss rolls, and similar solid products, individually or in multi-piece collations. The X-Fold variant suits single chocolates and small biscuits in envelope-style fold packs.

What is the difference between pillow pack and X-Fold wrapping?

Pillow pack wraps product in a film tube with a longitudinal fin seal and crimped ends — the standard biscuit pack. X-Fold wrapping folds film around a single piece envelope-style, typical for individual chocolates and premium single biscuits.

Can the machine handle printed branded film?

Yes. Photo-eye print-mark registration keeps printed graphics centered on every pack. Share your film specification and artwork layout and we will confirm compatibility.

How fast can it run?

Depending on the product and pack size, typical speeds range from 30 to 300 packs per minute. We confirm the achievable speed for your specific product and collation during project design.

Can it connect to my existing biscuit stacker or sandwiching machine?

Yes. We customize infeed height, orientation, and speed synchronization so the wrapper integrates with existing stackers, sandwiching machines, and feeding lines.
