The Pactur KLOK 550 is a shrink chamber machine that combines film sealing and shrinking in a single compact packaging system. Designed for companies that require professional shrink packaging without a separate shrink tunnel, it provides a practical solution for small and medium production requirements.

The KLOK 550 is a freestanding chamber machine equipped with PLC control and a touchscreen operator interface. Products are wrapped and shrunk inside the same chamber, making the machine compact, easy to operate and suitable for a wide range of packaging applications.

Designed and manufactured in Italy by Pactur, the KLOK 550 combines simple operation with the construction standards of an industrial shrink packaging machine.

How Does a Shrink Chamber Machine Work?

A shrink chamber machine performs two packaging operations within the same working area: film sealing and heat shrinking.

The operator positions the product inside the shrink film and closes the transparent hood. The machine completes the sealing cycle and circulates heated air inside the chamber, shrinking the film around the product. At the end of the cycle, the hood opens and the packaged product can be removed.

Because sealing and shrinking take place in a single machine, a chamber system requires less space than configurations using a separate sealing machine and shrink tunnel.

KLOK 550 Main Features

• 550 × 400 mm sealing area for a wide range of product dimensions;
• maximum package height up to 230 mm;
• PLC-controlled operation for consistent packaging cycles;
• touchscreen operator interface for machine settings and control;
• adjustable product support for correct positioning inside the chamber;
• film reel holder and micro-perforation system for shrink film preparation;
• heating elements and air circulation system designed for uniform film shrinking;
• robust metal construction for professional packaging environments;
• 230 V single-phase power supply.

Compact Shrink Packaging without a Separate Tunnel

One of the main advantages of the KLOK 550 is its ability to combine the sealing and shrinking processes in one machine.

This makes it particularly suitable when production requirements do not justify a fully automatic shrink wrapping line or when available floor space is limited.

The operator retains direct control over product loading while the machine manages the sealing and shrinking cycle, providing a practical intermediate solution between manual shrink packaging and automatic packaging systems.

Products and Applications

The KLOK 550 can be used for shrink packaging products from many different sectors. Typical applications include:

• food and bakery products;
• trays and packaged food products;
• cosmetics and personal-care products;
• pharmaceutical and healthcare products;
• books, printed products and stationery;
• small technical and hardware products;
• boxes, kits and grouped products;
• retail and e-commerce products requiring protective or presentation packaging.

The appropriate machine settings and shrink film depend on the dimensions, shape and characteristics of the product being packaged.

Shrink Films for the KLOK 550

The KLOK 550 can work with different shrink films according to the packaging application and required result.

Film selection should take into account product dimensions, film thickness, required transparency, mechanical resistance and shrinking characteristics. Pactur can evaluate the customer’s product and recommend the appropriate packaging configuration.

Made in Italy by Pactur

The KLOK 550 is designed and manufactured by Pactur in Zola Predosa, Bologna, Italy.

Direct control of production, assembly and testing allows Pactur to combine robust construction with technical support and application-specific packaging experience.

Customers can provide product samples for packaging tests, allowing Pactur to evaluate the appropriate machine settings and shrink film before defining the final solution.

Frequently Asked Questions about Shrink Chamber Machines

What is a shrink chamber machine?

A shrink chamber machine combines film sealing and heat shrinking in the same chamber. This eliminates the need for a separate shrink tunnel and creates a compact shrink packaging station.

What is the difference between the KLOK 35 and KLOK 550?

The KLOK 35 is a smaller table-top model, while the KLOK 550 is a freestanding machine with a 550 × 400 mm sealing area and is designed for larger products and greater production requirements.

When should I choose a chamber machine instead of an automatic shrink wrapper?

A chamber machine is particularly suitable for low to medium production requirements where compact dimensions and simple operator loading are important. Automatic shrink wrapping machines are generally more appropriate when continuous product flow and higher levels of automation are required.

Can Pactur test my product?

Yes. Product samples can be evaluated to help determine the appropriate machine configuration, film and packaging parameters.
