A flow wrapping machine is an automated packaging system that surrounds products with a continuous flexible film. The machine forms a longitudinal seal and two end seals 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 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
As the item travels forward, the machine forms the flexible film around it.
3. Sealing Along the Pack
A longitudinal seal joins the film beneath or above the product, forming a continuous tube.
4. End Sealing and Cutting
Cross seals are formed at each end before the package is cut from the continuous film.
5. The Completed Pillow Pack
The sealed package exits the machine and can then be stored, distributed or displayed.
What Are the Benefits of Flow Wrapping Machines?
Many manufacturers invest in flow wrapping machinery to increase production efficiency while maintaining packaging quality.
Fast Packaging Output
Automatic systems can package thousands of products per hour, depending on the product and machine specification.
Uniform Seals and Appearance
The machine applies consistent seals and pack formatting to every item. 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
A closed flow-wrapped pack provides protection from dust, damp conditions, contamination and physical contact during distribution and storage.
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.
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
Flow wrapping is used throughout many industries because it can handle both edible products and manufactured items.
Which Packaging Films Work with Flow Wrappers?
Different film materials can be used according to the packaging requirements.
Common materials include:
- Biaxially oriented polypropylene film
- Polyolefin film
- Polyethylene film
- PET film
The correct material will be determined by the product type, storage period, presentation requirements and production setting.
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
- 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.
Important features include:
- Packaging speed
- Supported product dimensions
- Fast and straightforward changeovers more info
- Photocell registration for printed films
- Date and batch-code printing
- Automatic feeding integration
- User-friendly 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?
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.
Shrink wrapping places film around the item and then uses heat to contract it closely around the outside.
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?
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.
