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.

Because of its shape, the finished package is commonly known 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 wrap products at a steady production rate.

1. Products Enter the Machine

A conveyor or connected feeding system automatically moves products into the machine.

2. Film Forming

The machine guides the film around each product during the packaging process.

3. The Length Seal Is Formed

The film is sealed along its length to create a continuous tube around the product.

4. Cross Sealing and Cutting

The machine creates end seals and then separates each pack from the film web.

5. Finished Product

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.

Fast Packaging Output

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

Flow wrapping machinery limits the need for employees to wrap every product by hand. Staff can therefore spend less time on repetitive packaging work.

A Protective Film Barrier

The sealed film can shield products against dirt, moisture, contamination and handling damage during warehousing, handling and delivery.

Packaging for Different Products

The equipment can be configured for varied product formats and packaging materials.

Common Flow Wrapping Applications

Flow wrapping machinery can be used for many food and non-food products.

Common examples include:

• Individual or grouped biscuits
• Cakes, bread products and other bakery goods
• Chocolate and confectionery
• Fresh produce
• Frozen foods
• Medical products and devices
• Pharmaceutical goods
• Cosmetics and personal care items
• 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?

The correct flexible film will depend on the item being packed and the conditions it must withstand.

Frequently used films include:

• BOPP film
• Polyolefin packaging film

• Polyethylene film
• PET film

Film selection should take account of the item, shelf-life needs, pack appearance and operating conditions.

Should Your Business Move to Automatic Flow Wrapping?

An automatic flow wrapper may become suitable when manual processes start slowing the production line.

A flow wrapping machine may be suitable if:

• Production volumes continue to increase
• Manual packaging slows the production line
• Pack appearance or seal quality is inconsistent
• Greater consistency is required
• Manual packaging is becoming more expensive

A suitable flow wrapper can raise output and produce more uniform packaging.

How Do You Choose a Flow Wrapping Machine?

Several factors should be considered when selecting flow wrapping machinery.

Specifications to review include:

• Maximum production speed
• Product size capacity
• Fast and straightforward changeovers
• Photocell registration for printed films
• Date and batch-code printing
• Compatibility with automatic feeding systems
• User-friendly controls
• Consistent and dependable seals

Your product range, packaging volume and projected demand should guide the final machine specification.

How Do Flow Wrappers Differ from Shrink Wrap Machines?

Although both methods use flexible film, the packaging processes are different.

A flow wrapper creates a closed pillow-shaped pack using continuous film.

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. Current flow wrappers may be installed as part of an established production system.

The machine can work alongside feeding units, conveyor systems and labelling equipment. This allows manufacturers to add automated packaging without making major changes to the full production line.

Questions About Flow Wrapping Machinery

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 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.

Can a Flow Wrapper Be Used for Manufactured Goods?

Yes, they can. Manufacturers use flow wrapping machinery for pharmaceutical products, medical devices, hardware, cosmetics and consumer goods.

How Many Products Can a Flow Wrapper Package?

The production rate varies according to product dimensions and machine specification. Many high-performance machines can wrap several thousand products per hour.
