The Buyer's Guide

Flow Wrap Machine: The Complete Buying Guide In 2024

Bartelt Harold and Donald Bartelt developed a machine that can fill and seal pre-made envelopes for electrical components.This invention which was fast and labor-saving paved the way to the development of first ever horizontal form fill and seal machines or HFFS.

Flow wrapping machine is a type of HFFS that employs single roll of film to make horizontal bags; because of this out of many packaging processes flow wrapping is one of the most commonly used method employed by packaging experts in the industry to pack products of any shape or size.

This blog will pique your interest with facts about flow wrapping, flow wrap machine and a brief comparison of flow wrap equipment with other packaging instruments. Bringing you Flow Wrap Machine: The Complete Buying Guide In 2023. In this blog we will cover.

    1.What is flow wrapping?

    Flow wrapping also known as Horizontal Form-Fill-Seal (HFFS) is a type of primary packaging process employed in food, confectionary, cosmetic and health care industries to protect products from degradation, spoilage and contamination. Flow wrapping is brought about by flow wrapping machines or flow wrappers that employ heat sealable films such as PET/PE, nylon etc. for packaging.

    flow wrapping

    Flow wrappers use heat and pressure to make an uptight seal which prevents unnecessary movement of the product. Some flow wrapping machines are also equipped with gas flushers that further stabilizes the products against environmental degradation.

    2.Flow wrapping vs overwrapping. What is the difference?

    You will find a number of packaging that sound similar but serve different purposes, each having their own advantages and uses. Flow wrapping and overwrapping are example of such packaging process. Differences between these two packaging processes are given below.

    Flow wrapping Over wrapping
    flow wrapping-1 Over wrapping
    • Flow wrapping is used for products of any shape.
    • This packaging is mainly used as primary packaging.
    • This process is carried out using flow wrappers or flow wrap machines.
    • Packaging film encircles the product making an airtight seal using heat pressure and ultrasound.
    • Protects material from environmental conditions and degradation.
    • Overwrapping is used for products with flat shape i.e. cartons, boxes etc.
    • Overwrapping is mainly used for secondary packaging.
    • The equipment used in this process are called as over wrappers.
    • Produces envelope like seal that also encircles the product.
    • Used for wrapping multiple packages into a single packages for ease of delivery and storage.

    3.Equipment required to perform flow wrapping; a brief overview.

    The process of making pouches of different sizes and shapes, filling and sealing of products whether a chocolate bar or any medical device by unwinding of film is done by machines known as flow wrappers. These machines are low on budget, serve multipurpose and provide total control of packaging processes.

    Components of Flow wrap machine

    10.Flow wrap vs sachet machine vs Doypack machine; a comparison.

    Packaging machines are all similar in working principle i.e. they pack, fill and seal products but each machine produces distinctive packages, all because of units or parts that are unique to that machine. Below is a comparison between three popular packaging equipment

    Sachet packing machine Doypack machine Doypack machine
    Sachet packing machine Doypack machine Flow wrap machine
    1) This machine can produce 3 sides, 4 sides or a central seal with a tearing notch or cap for ease of opening.
    2) This machine can be customized to stack, count and weigh sachets.
    3) A standard version can produce 150 sachets in a minute.
    1) The unique feature of doypacks to stand in an upright position is because of W or S-fold bases. This machine differs from other machines in a specialized unit that make W and S-fold.
    2) Typically this machine also has a unit that attaches bottle cap or zipper and can fill pre-made pouches.
    3) Smallest doypack is bigger in size than sachets or flow wraps, a standard doypack model can produce up to 90 pouches is a minute.
    1) Flow wraps are not pre made pouches, these are made by wrapping film around products and sealing the edges together. This wrapping is performed by the unit known as former or folding unit.
    2) With this machine you can wrap product of any geometric shape.
    3) A standard version of flow wrapper can produce up to 150-250 flow wraps in a minute.

    11.Difference between flow wrap machine and shrink wrap machine.

    Another machine that is very much similar to flow wrap machine is shrink wrap machine. Few difference between both HFFS machines are given below;

    flow wrapping-61 Shrink wrap machine
    Flow wrap machine Shrink wrap machine
    1) Flow wrap machines are used as primary packaging as well as secondary packaging equipment.
    2) Any suitable film is wrapped around the product and the edges are sealed with either heating or ultrasound.
    3) Products that can be flow wrapped include food and confectionary items, medical devices etc.
    4) This machine offers minimal movement within the wrap thereby reducing unwanted wastage.
    1) Shrink machines are mostly used for secondary packaging.
    2) Transparent film is wrapped around the product which then runs through a heating chamber that shrinks it.
    3) Meat, books, bottles and vegetables can be shrink wrapped using this machine.
    4) It is cost effective, protects from dirt and humidity allows better storage.
