How to Choose a Flow Wrap Machine: Complete Buying Guide for South African Manufacturers

Choosing the right flow wrap machine is one of the most important decisions for any packaging operation. The right machine can improve productivity, reduce packaging waste, maintain consistent seal quality and support future business growth. Selecting the wrong machine, however, can lead to unnecessary downtime, higher operating costs, increased film waste and expensive upgrades.

Every manufacturing business has unique packaging requirements. Factors such as product size, shape, production speed, packaging material and automation requirements all influence which machine is best suited to your operation. A flow wrap machine that performs well in a bakery may not be the ideal solution for packaging medical devices, hardware or confectionery products.

Whether you are investing in your first packaging machine or upgrading an existing production line, taking the time to evaluate your requirements can help you maximise your return on investment and avoid costly mistakes.

This buying guide explains the most important factors to consider when choosing a flow wrap machine, helping you compare available options and make an informed purchasing decision.

Shrink Wrap vs Flow Wrap

What Is a Flow Wrap Machine?

A flow wrap machine, also known as a horizontal flow wrapping machine, is an automated packaging system that wraps individual products in a continuous roll of flexible packaging film. The machine forms the film around the product, seals it along the length and ends of the package, and cuts each finished pack to size in one continuous process.

Flow wrapping is widely used because it offers fast production speeds, consistent packaging quality and excellent product protection. It is suitable for packaging a wide range of products across industries, including:

  • Bakery products
  • Biscuits and confectionery
  • Fresh produce
  • Medical devices
  • Pharmaceuticals
  • Cosmetics
  • Hardware components
  • Stationery
  • Household products
  • Promotional packs

Many modern flow wrap machines can operate with printed or plain packaging films, making them suitable for both retail-ready packaging and industrial applications. If you’re new to this packaging technology, read our guide on What Is a Flow Wrap Packaging Machine? before continuing.

Step 1: Understand Your Product

The first step in choosing a flow wrap machine is understanding the characteristics of the product you intend to package. Every machine is designed to operate within specific size, weight and product handling limits. Matching the machine to your product ensures reliable operation, high-quality seals and efficient production.

Before speaking to a packaging supplier, record the following information for every product you intend to package.

Measure Your Product Dimensions

Accurate product measurements are essential when selecting the correct flow wrap machine.

Measure the following:

  • Length
  • Width
  • Height
  • Overall shape

These dimensions determine:

  • The required film width
  • The size of the forming box
  • Sealing jaw dimensions
  • Conveyor width
  • Machine configuration

Products that vary significantly in size may require adjustable guides or quick-change tooling to minimise changeover times.

Tip: Always measure the largest product that the machine will need to package, rather than the average size.

Consider Product Weight

Product weight also plays an important role in machine selection.

Lightweight products generally move easily through the machine, while heavier products require stronger conveyors and stable product handling systems to maintain consistent spacing throughout the packaging process.

For heavier products, your supplier may recommend:

  • Heavy-duty conveyors
  • Reinforced machine frames
  • Larger drive motors
  • Stronger sealing systems

Selecting equipment designed for the correct product weight helps improve machine reliability and reduces unnecessary wear on moving components.

Consider Product Shape

Not every product moves through a flow wrapper in the same way.

Some products are:

  • Flat
  • Round
  • Cylindrical
  • Flexible
  • Fragile
  • Irregularly shaped

Each shape presents different handling requirements.

For example, delicate bakery products may require gentle infeed systems to prevent damage, while cylindrical products often need product guides to stop them from rolling during packaging. Fragile medical devices or precision components may require customised handling systems to ensure accurate positioning before sealing.

The more information you can provide about your product, the easier it becomes to recommend a machine that delivers reliable packaging performance.

Think About Your Product Range

Many manufacturers package more than one product using the same machine.

If your business regularly packages products with different dimensions, consider selecting a machine that offers:

  • Adjustable product guides
  • Stored machine recipes
  • Quick changeover features
  • Servo-driven adjustments
  • Flexible forming boxes

These features reduce setup time and allow operators to switch between products more efficiently, helping improve overall production output.

Step 2: Determine Your Production Throughput

Production speed is another key factor when choosing a flow wrap machine. Purchasing a machine that is too slow can create production bottlenecks, while investing in equipment that significantly exceeds your requirements may increase costs unnecessarily.

Start by determining how many products you need to package during a typical production shift.

Consider questions such as:

  • How many products do you produce each day?
  • How many packs per minute are required?
  • Do you operate one shift or multiple shifts?
  • Are there seasonal increases in demand?
  • Will production volumes increase over the next few years?

Your answers will help determine the most suitable machine capacity.

Lower Production Volumes

Businesses with lower production volumes often benefit from entry-level flow wrap machines that offer reliable packaging performance without the complexity of fully automated systems.

These machines are well suited for:

  • Small manufacturers
  • Start-up businesses
  • Pilot production
  • Speciality food producers
  • Contract packaging operations

Medium Production Volumes

Manufacturers with consistent production requirements generally benefit from servo-driven flow wrap machines that offer improved speed, greater accuracy and faster product changeovers.

These machines provide an excellent balance between production capacity, efficiency and long-term operating costs.

High Production Volumes

Large-scale manufacturers typically require fully automated flow wrap systems capable of operating continuously at high speeds.

These systems often include:

  • Automatic product feeding
  • Conveyor integration
  • Product spacing systems
  • Print registration control
  • Automatic rejection systems
  • Date coding integration

High-speed production lines help maximise productivity while maintaining consistent package quality across thousands of products per hour.

Plan for Future Demand

While your current production requirements are important, it is equally important to consider where your business will be in three to five years.

If you expect to introduce new product lines, expand into retail markets or increase production volumes, selecting a machine with additional capacity can reduce the need for future equipment upgrades.

Investing in a machine that supports business growth often delivers better long-term value than purchasing equipment designed only for today’s production requirements.

Step 3: Choose the Right Infeed System

The infeed system is responsible for delivering products into the flow wrap machine at the correct speed and spacing. Choosing the right infeed system helps ensure smooth production, reduces product damage and improves overall packaging efficiency.

The best option depends on your production volume, product characteristics and level of automation required.

Manual Feeding

Manual feeding involves an operator placing products directly onto the machine’s infeed conveyor.

This option is commonly used by businesses with lower production volumes or operations that package a wide variety of products in smaller batches.

Manual feeding is suitable for:

  • Small manufacturers
  • Artisan bakeries
  • Contract packers
  • Start-up businesses
  • Seasonal production
  • Products with frequent size changes

Advantages of Manual Feeding

  • Lower initial investment
  • Simple to operate
  • Flexible for different product sizes
  • Ideal for shorter production runs
  • Easier to introduce new products

Considerations

Although manual feeding offers flexibility, production speed depends on the operator. As production volumes increase, manual loading may become a bottleneck that limits output.

Automatic Feeding

Automatic feeding systems transfer products directly from upstream production equipment into the flow wrap machine without manual intervention.

These systems are commonly integrated with conveyors, counting systems, robotic pick-and-place units or product spacing conveyors.

Automatic feeding is ideal for manufacturers producing high volumes where speed and consistency are essential.

Automatic feeding is commonly used for:

  • Bakery products
  • Biscuits
  • Confectionery
  • Medical devices
  • Pharmaceutical products
  • Personal care products
  • Household goods
  • Industrial components

Advantages of Automatic Feeding

  • Higher production speeds
  • Consistent product spacing
  • Reduced labour requirements
  • Lower risk of operator error
  • Improved packaging consistency
  • Better integration with complete production lines

Automatic feeding systems also help minimise product jams by maintaining accurate spacing between products before they enter the sealing section.

Step 4: Select the Right Packaging Film

Packaging film plays a major role in the appearance, protection and performance of your finished product. Before purchasing a flow wrap machine, ensure it is compatible with the film types you intend to use.

Different products require different film characteristics depending on factors such as moisture protection, product shelf life, branding requirements and sealing performance.

Plain Film

Plain (unprinted) film is commonly used for industrial packaging and products where branding is not required.

Advantages include:

  • Lower packaging costs
  • Faster lead times
  • Simpler inventory management
  • Suitable for bulk or industrial products

Printed Film

Printed film allows manufacturers to display branding, nutritional information, barcodes, product instructions and promotional messaging directly on the packaging.

When using printed film, your flow wrap machine should include print registration sensors that accurately align the packaging artwork with each product.

Benefits include:

  • Professional retail presentation
  • Stronger brand recognition
  • Improved shelf appeal
  • Consistent print alignment
  • Better customer experience

Barrier Films

Certain products require additional protection from moisture, oxygen or contaminants.

Barrier films help extend product shelf life by reducing exposure to external environmental conditions.

Barrier films are commonly used for:

  • Food products
  • Coffee
  • Snacks
  • Medical products
  • Pharmaceutical items

Film Width and Thickness

Not every machine supports every film size.

When comparing machines, confirm the supported:

  • Minimum film width
  • Maximum film width
  • Film thickness range
  • Roll diameter
  • Core size

Using the correct film specifications helps produce strong, consistent seals while reducing unnecessary film waste.

Machine Compatibility

Before making your final decision, confirm that the machine supports:

  • Printed films
  • Plain films
  • Laminated films
  • Heat-sealable materials
  • Future packaging materials your business may introduce

Selecting a machine with greater film flexibility gives your business more options as customer requirements evolve.

Step 5: Plan for Future Growth

Purchasing a flow wrap machine is a long-term investment. While it’s important to meet your current production needs, it’s equally important to consider how your business may grow over the next several years.

Many companies outgrow their first packaging machine sooner than expected because production increases, new products are introduced or customer requirements change.

Planning ahead can help you avoid unnecessary equipment replacements and minimise future capital expenditure.

Consider Future Production Volumes

Ask yourself:

  • Will production increase over the next three to five years?
  • Will you introduce additional shifts?
  • Are you planning to expand into retail packaging?
  • Could export opportunities increase demand?
  • Will additional product lines require packaging?

Choosing a machine with extra production capacity provides greater flexibility as your business grows.

Think About Product Expansion
