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.
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?
Automatic flow wrapping equipment 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. Packaging Film Positioning
The machine guides the film around each product during the packaging process.
3. Longitudinal Sealing
The film is sealed along its length to create a continuous tube around the product.
4. Cross 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 completed pillow pack leaves the machine ready for storage, transport or retail display.
Why Use a Flow Wrapping Machine?
Businesses often choose flow wrapping machines when they need faster production and repeatable packaging results.
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
Products pass through the same controlled sealing process. This can help maintain a uniform brand appearance.
Reduced Labour Costs
Automation reduces the amount of manual handling needed during packaging. Staff can therefore be assigned to other duties.
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.
Which Products Can Flow Wrapping Machinery Package?
Flow wrapping machinery can be used for many food and non-food products.
Common examples include:
- Individual or grouped biscuits
- Bakery products
- Sweets, chocolate bars and confectionery
- Fresh produce
- Frozen foods
- Medical products and 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.
Which Packaging Films Work with Flow Wrappers?
Different film materials can be used according to the packaging requirements.
Available film options include:
- BOPP film
- Polyolefin packaging film
- Polyethylene film
- 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.
A flow wrapping machine may be suitable if:
- 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
- Fast and straightforward changeovers
- Photocell registration for printed films
- Integrated date or batch coding read more
- Compatibility with automatic feeding systems
- Clear operator controls
- Consistent and dependable seals
The correct choice depends on your products, current production volume and future growth plans.
What Is the Difference Between Flow Wrapping and 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
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.
