Clip closure for Bag Closures in Food, Bakery and Industry | OPTI-PACK

Clip closures for bag closures — food, bakery and industry

Clip closure is the most widely used method for closing packaging bags quickly, securely and resealably. OPTI-PACK is the official supplier of IROSTEL clip closures in the Netherlands and Belgium, serving production companies, bakeries and packaging businesses on reel or pre-cut, for manual and fully automated packaging lines.

The clip closure is compatible with clip closing machines from COMIPAK, COMIZ, ZENATOR, THÜRLINGS, OPTIMA and other commonly used systems. Unsure about compatibility? We advise you upfront based on your machine and packaging process.

 

What is a clip closure?

Clip closure is a flexible bag closure consisting of a metal wire core with a plastic or paper outer layer. The combination of flexibility and strength makes it a reliable, resealable closure that can be applied both manually and automatically.

In practice, clip closures ares used to close bread bags, pasta and rice bags, snack packaging, confectionery, chocolate and fresh produce packaging. Application is straightforward, the closure is strong, and the packaging looks neat, even after opening and resealing multiple times.

On an automated packaging line, a closing machine processes hundreds of bags per hour without operator intervention. Clip closure is engineered for these speeds: tightly wound, uniform wire core diameter and an outer layer that runs smoothly through the machine.

What is the difference between clip closure and twist tie?


Clip closure and twist tie are both used to close packaging bags, but they work differently and are not always interchangeable.

- **Clip closure** is clamped around the bag using a clip mechanism. The closure is tight, strong and suited to higher production speeds. Widely used in industrial bakeries and food production.
- **Twist tie** is twisted around the bag and secured. Application is simpler but the closure is slightly less tight. More commonly used for lighter packaging and manual processing.
- **Which to choose:** for automated lines with high capacity, clip closure is the standard choice. Twist tie is more often chosen for manual processing or lighter packaging.

OPTI-PACK supplies both variants and advises you on which best suits your machine, your product and your production capacity.

Advantages of clip closures 

Clip closure performs well across multiple practical criteria at once. The closure is strong and consistent, regardless of whether the machine runs at low or high speed. The packaging is resealable, which is a concrete benefit for consumers. The material is available in a range of colours, so clip closure can also be used for colour coding by product, best-before date or production line.

- Strong, consistent closure at any production speed
- Resealable, packaging remains usable after opening
- Available in multiple colours for colour coding
- Suitable for printing and branding
- Compatible with virtually all commonly used closing machines
- Available for food and non-food applications
- On reel or pre-cut, depending on your machine
 

Clip closure applications

Clip closure for the food industry and bakeries

The largest users of clip closures are bakeries and food manufacturers. Bread packaging, pastry packaging, pasta and rice bags, snacks, chocolate, confectionery and fresh produce packaging are closed with clip tape every day, both manually and via automated closing machines.

In industrial bakeries, closing machines run continuously, where consistent closure quality and low susceptibility to downtime are decisive. IROSTEL clip closures are designed for this: tightly wound, uniform wire core diameter and an outer layer that runs smoothly through the machine.
 

Clip closure for retail and consumer packaging

In retail, resealable packaging is becoming increasingly important. Clip closure offers a straightforward way to open and reclose packaging multiple times without any loss of quality. Applications include gift packaging, shop packaging and consumer packaging where presentation matters.
 

Industrial applications

Outside the food sector, clip closure is used for bundling small components, technical products, cables and assembled product sets. The flexibility of the material makes it suitable for a wide range of shapes and sizes.

U-Clips for manual bag closure

Alongside clip closure on reel, IROSTEL also supplies U-Clips: pre-formed closure clips for manual bag closing without a machine. U-Clips are ideal for bakeries, chocolatiers, delicatessens and other smaller production environments where speed and flexibility matter more than full automation.

U-Clips are quick to apply, give a neat finish and are suitable for a range of bag sizes. For businesses that want to work without equipment but still achieve a reliable, professional closure, U-Clips are the practical choice.

Clip closure specifications, on reel and pre-cut

IROSTEL clip closure is available in several variants, matched to your closing machine and packaging process:

- PP clip tape with double metal wire
- Wire diameter from 0.6 to 0.8 mm
- Available on reel or pre-cut
- Available in multiple colours for colour coding
- Suitable for printing and branding
- Applicable in food and non-food industries
- Compatible with automatic closing machines from COMIPAK, COMIZ, ZENATOR, THÜRLINGS and OPTIMA

The choice between reel and pre-cut depends on your machine and your processing speed. We advise you based on your specific situation.

Sustainable clip closures

More and more producers are looking for packaging solutions with a lower environmental impact. IROSTEL offers concrete alternatives: kraft paper clip tape, biodegradable variants and versions with reduced plastic content made from recycled material.
