Flow Wrapping Machines Explained
A automatic flow wrapping system is an automated packaging system that encloses products in flexible film. The machine forms a seal along the length of the pack and seals at both ends to create a closed package.
Because of its shape, the finished package is commonly known as a pillow pack.
Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for manufacturers processing high volumes of products.
How Does Flow Wrapping Machinery Work?
A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.
1. Automatic Product Feeding
A conveyor or connected feeding system automatically moves products into the machine.
2. Film Forming
The machine guides the film around each product during the packaging process.
3. Longitudinal Sealing
The machine seals the film lengthways so that it surrounds the product in a tube.
4. End Sealing and Cutting
End-sealing jaws close the package before cutting it into an individual pack.
5. Finished Product
The sealed package exits the machine and can then be stored, distributed or displayed.
Advantages of Flow Wrapping Machinery
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
Increased Production Rates
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Repeatable Pack Presentation
Products pass through the same controlled sealing process. This can help maintain a uniform brand appearance.
Less Manual Handling
An automated system reduces hands-on work throughout the wrapping process. Staff can therefore focus on other production tasks.
Product Protection
The sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.
Flexible Packaging Options
Current flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.
What Can Be Packaged Using a Flow Wrapper?
The process can package products from several different sectors.
Typical applications include:
- Individual or grouped biscuits
- Bakery products
- Chocolate and confectionery
- Fresh produce
- Selected frozen products
- Medical devices
- Pharmaceutical products
- Personal care products
- Household goods
- Small industrial and hardware parts
Its suitability for food and non-food applications makes flow wrapping a common packaging method in manufacturing.
Which Packaging Films Work with Flow Wrappers?
A flow wrapping machine can use several flexible packaging films depending on the product and application.
Frequently used films include:
- BOPP film get more info
- Polyolefin packaging film
- Polyethylene film
- PET film
Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.
When Should You Invest in a Flow Wrapping Machine?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
You may benefit from upgrading when:
- Production volumes continue to increase
- Hand wrapping creates a production bottleneck
- Pack appearance or seal quality is inconsistent
- Greater consistency is required
- Labour costs are increasing
Automation may provide steadier production without reducing packaging consistency.
What Features Should You Look for in Flow Wrapping Machinery?
The correct machine should be chosen according to the product and production requirements.
Useful machine features include:
- Maximum production speed
- Supported product dimensions
- Easy product changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Automatic feeding integration
- User-friendly controls
- Reliable sealing performance
Machine suitability will be determined by the items being packed, required output and expected business growth.
How Do Flow Wrappers Differ from Shrink Wrap Machines?
Both systems package products in flexible material, although their operating methods differ.
A flow wrapping machine forms a sealed pillow pack from a continuous roll of film.
A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.
The choice will depend on the desired pack format, the product and how it will be stored or transported.
Can a Flow Wrapper Integrate with Existing Equipment?
Yes. Many flow wrapping machines are designed to connect with existing production equipment.
Compatible equipment may include automatic feeders, conveyors and labelling systems. This allows manufacturers to increase packaging output without rebuilding the entire production process.

Questions About Flow Wrapping Machinery
What Does a Flow Wrapper Package?
A flow wrapping machine creates sealed film packs around individual items. These packs can help shield items while they are stored, delivered or presented for sale.
Are Flow Wrappers Used for Food Packaging?
Yes. Flow wrapping is widely used for biscuits, cakes, sweets, snack products and produce. It provides closed packaging that supports hygienic handling.
Can a Flow Wrapper Be Used for Manufactured Goods?
Yes. Manufacturers use flow wrapping machinery for a range of healthcare, industrial and consumer products.
How Fast Can Flow Wrapping Machines Operate?
The production rate varies according to product dimensions and machine specification. Many high-performance machines can produce several thousand sealed packs in an hour.
