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.
The finished format is usually described as a pillow pack.
Unlike manual packaging methods, flow wrapping machines are built for continuous production. This makes the equipment suitable for manufacturers processing high volumes of products.
How Does Flow Wrapping Machinery Work?
Automatic flow wrapping equipment uses a continuous roll of flexible film to wrap products at a steady production rate.
1. Product Feeding
Products enter the wrapping section through an automatic conveyor or feeding arrangement.
2. Packaging Film Positioning
As the item travels forward, the machine forms the flexible film around it.
3. Longitudinal Sealing
A longitudinal seal joins the film beneath or above the product, forming a continuous tube.
4. End Sealing and Cutting
End-sealing jaws close the package before cutting it into an individual pack.
5. Finished Product
Once sealed and cut, the finished pack moves out of the machine ready for handling, delivery or sale.
What Are the Benefits of Flow Wrapping Machines?
Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.
Increased Production Rates
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Uniform Seals and Appearance
Each product receives the same seal quality and presentation. This can help produce a consistent presentation across a production run.
Lower Operator Requirements
Automation reduces the amount of manual handling needed during packaging. 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
The equipment can be configured for varied product formats and packaging materials.
Which Products Can Flow Wrapping Machinery Package?
A flow wrapper is suitable for a wide selection of food and manufactured goods.
Products frequently packaged in this way include:
- Individual or grouped biscuits
- Cakes, bread products and other bakery goods
- Chocolate and confectionery
- Fruit and vegetables
- Frozen foods
- Medical devices
- Pharmaceutical products
- Cosmetics and personal care items
- Household goods
- Hardware components
Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.
What Films Can a Flow Wrapping Machine Use?
A flow wrapping machine can use several flexible packaging films depending on the product and application.
Available film options include:
- Biaxially oriented polypropylene film
- Polyolefin film
- Polyethylene film
- Polyethylene terephthalate film
The correct material will be determined by the product type, storage period, presentation requirements and production setting.
When Is It Time to Use Flow Wrapping Machinery?
Many businesses move to automatic flow wrapping when manual packaging begins to restrict production.
A flow wrapping machine may be suitable if:
- Production volumes continue to increase
- Hand wrapping creates a production bottleneck
- Packaging quality varies between operators
- You need more repeatable packaging results
- Manual packaging is becoming more expensive
A suitable flow wrapper can raise output and produce more uniform packaging.
Key Flow Wrapper Features
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 more info
- Automatic feeding integration
- User-friendly controls
- Reliable sealing performance
Your product range, packaging volume and projected demand should guide the final machine specification.
Flow Wrapping Versus Shrink Wrapping
Although both methods use flexible film, the packaging processes are different.
A flow wrapper creates a closed pillow-shaped pack using continuous film.
Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.
Businesses should consider presentation, product characteristics and post-production handling when selecting a system.
Flow Wrapping Machine Integration
In many cases, yes. Current flow wrappers may be installed as part of an established production system.
Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to raise production capacity without replacing every existing system.

Flow Wrapping Machine FAQs
What Is the Purpose of Flow Wrapping Machinery?
A flow wrapping machine wraps separate products in flexible packaging film and produces closed pillow-shaped packs. These packs can protect products during storage, transport and retail display.
Can Food Be Packaged with a Flow Wrapper?
Yes, they are. Flow wrapping is widely used for bakery goods, confectionery, snacks and fresh produce. It provides a hygienic sealed pack.
Are Flow Wrappers Suitable for Non-Food Items?
Yes. Manufacturers use flow wrapping machinery for medical items, pharmaceuticals, small components, personal care goods and household 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.
