A automatic flow wrapping system is an automated packaging system that wraps individual products in flexible packaging 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.
Rather than relying on repeated manual wrapping, flow wrapping machinery supports a continuous packaging process. This makes the equipment suitable for production lines that require fast and consistent packaging.
How Do Flow Wrapping Machines 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. The Film Is Formed Around the Product
The packaging film is shaped around each product as it moves through the machine.
3. The Length Seal Is Formed
A longitudinal seal joins the film beneath or above the product, forming a continuous tube.
4. The Pack Is Sealed and Separated
Cross seals are formed at each end before the package is cut from the continuous film.
5. The Completed Pillow Pack
The completed pillow pack leaves the machine ready for storage, transport or retail display.
Why Use a Flow Wrapping Machine?
Flow wrapping equipment can help manufacturers improve output and produce consistent packs.
High Production Speeds
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 maintain a uniform brand appearance.
Reduced Labour Costs
Flow wrapping machinery limits the need for employees to wrap every product by hand. 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.
Packaging for Different Products
Current flow wrapping systems can handle a broad selection of product dimensions, shapes and film types.
What Can Be Packaged Using a Flow Wrapper?
A flow wrapper is suitable for a wide selection of food and manufactured goods.
Common examples include:
- Individual or grouped biscuits
- Bakery products
- Sweets, chocolate bars and confectionery
- Fruit and vegetables
- Frozen foods
- Medical products and devices
- Pharmaceutical products
- Cosmetics and personal care items
- Household goods
- Small industrial and hardware parts
Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.
Which Packaging Films Work with Flow Wrappers?
A flow wrapping machine can use several flexible packaging films depending on the product and application.
Available film options include:
- BOPP film
- Polyolefin packaging film more info
- Polyethylene (PE)
- PET film
The most suitable film depends on the product, required shelf life, desired presentation and production environment.
When Is It Time to Use Flow Wrapping Machinery?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
A flow wrapping machine may be suitable if:
- Production volumes continue to increase
- Manual packaging slows the production line
- Packaging quality varies between operators
- You need more repeatable packaging results
- Manual packaging is becoming more expensive
Automatic packaging can improve productivity while maintaining consistent pack quality.
How Do You Choose a Flow Wrapping Machine?
Several factors should be considered when selecting flow wrapping machinery.
Important features include:
- Packaging speed
- Product size capacity
- 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.
Flow wrapping machinery forms film around the product before applying length and end seals.
A shrink wrap machine surrounds the product with shrink film before applying heat to tighten the material.
The right method depends on the required appearance, product type and handling conditions after packaging.
Can Flow Wrapping Machinery Be Added to an Existing Production Line?
In many cases, yes. Flow wrapping machinery can often be integrated with equipment already in use.
The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to raise production capacity without replacing every existing system.

Questions About Flow Wrapping Machinery
What Is a Flow Wrapping Machine Used For?
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, 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, they can. Manufacturers use flow wrapping machinery for pharmaceutical products, medical devices, hardware, cosmetics and consumer goods.
What Is the Speed of a Flow Wrapping Machine?
Packaging speed is affected by the equipment model, pack format and item being handled. Many high-performance machines can produce several thousand sealed packs in an hour.
