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 completed package is often called a pillow pack because of its shape.
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?
A flow wrapping machine uses a continuous roll of flexible film to package products quickly and consistently.
1. Automatic Product Feeding
Products enter the wrapping section through an automatic conveyor or feeding arrangement.
2. Packaging Film Positioning
The machine guides the film around each product during the packaging process.
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
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.
Why Use a Flow Wrapping Machine?
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
Fast Packaging Output
Depending on the machine model and product dimensions, a flow wrapper may package several thousand items each hour.
Consistent Packaging Quality
The machine applies consistent seals and pack formatting to every item. This can help keep retail packs neat and recognisable.
Lower Operator Requirements
Automation reduces the amount of manual handling needed during packaging. Staff can therefore focus on other production tasks.
Product Protection
A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during warehousing, handling and delivery.
Packaging for Different Products
Modern machines can package many product sizes and shapes using different flexible films.
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:
- Biscuits
- Bakery products
- Sweets, chocolate bars and confectionery
- Fruit and vegetables
- Frozen foods
- Medical products and devices
- Pharmaceutical goods
- Personal care products
- Domestic and consumer products
- Small industrial and hardware parts
Because it can package both food and non-food goods, flow wrapping is widely used across manufacturing industries.
Which Packaging Films Work with Flow Wrappers?
Different film materials can be used according to the packaging requirements.
Frequently used films include:
- Biaxially oriented polypropylene film
- Polyolefin film
- Polyethylene (PE) here
- PET film
The most suitable film depends on the product, required shelf life, desired presentation and production environment.
Should Your Business Move to Automatic Flow Wrapping?
Companies often adopt flow wrapping machinery when hand packaging can no longer keep pace with demand.
You may benefit from upgrading when:
- Your required packaging output is rising
- Manual packaging slows the production line
- Packaging quality varies between operators
- You need more repeatable packaging results
- Labour costs are increasing
Automation may provide steadier production without reducing packaging consistency.
How Do You Choose a Flow Wrapping Machine?
Machine selection requires an assessment of pack format, output and future demand.
Specifications to review include:
- Maximum production speed
- Supported product dimensions
- Fast and straightforward changeovers
- Printed-film registration using photocells
- Date and batch-code printing
- Compatibility with automatic feeding systems
- Clear operator controls
- Reliable sealing performance
Your product range, packaging volume and projected demand should guide the final machine specification.
What Is the Difference Between Flow Wrapping and Shrink Wrapping?
Flow wrapping and shrink wrapping both involve film, but they form packs in different ways.
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 choice will depend on the desired pack format, the product and how it will be stored or transported.
Can Flow Wrapping Machinery Be Added to an Existing Production Line?
Yes. Many flow wrapping machines are designed to connect with existing production equipment.
Integration options commonly include automatic product feeders, conveyors and label applicators. This allows manufacturers to increase packaging output without rebuilding the entire production process.

Flow Wrapping Machine FAQs
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.
Is Flow Wrapping Suitable for Food Products?
Yes. Flow wrapping is widely used for many bakery, confectionery, snack and fresh-food applications. It provides secure and hygienic packaging.
Are Flow Wrappers Suitable for Non-Food Items?
Yes, they can. 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.
