In the world of packaging, heat shrinking is one of the most popular techniques for protecting, sealing and presenting any product in the best possible way. Among the most effective and professional solutions available on the market, bell packaging machines stand out, machines designed to guarantee speed, precision and versatility in packaging with heat shrink film.

How does a bell packaging machine work?

Bell packaging machines are machines that seal and heat shrink a plastic film around the product in a single operation, thanks to an integrated system. Operation is simple and highly efficient:

1. The operator inserts the product into the heat shrink film (in PVC or polyolefin).
2. The product is positioned on the base of the machine and covered by the transparent bell.
3. The bell lowers and starts the cycle: the film is sealed and immediately subjected to a heat source, which causes it to retract.
   Once the cycle is complete, the bell lifts automatically (in automatic or semi-automatic versions) and the product is ready.
4. The result? A resistant, adherent, clean and professional package.

The result? A sturdy, tight, clean and professional package.

PVC and Polyolefins: the most used materials

Chamber packaging machines work with heat-shrinkable plastic films such as:

• PVC (polyvinyl chloride): ideal for light products and for aesthetic packaging both technical and food, thanks to its transparency and rigidity.
• Polyolefins: a more elastic, resistant material also suitable for food applications or packaging that requires greater strength.
  The choice of film depends on the type of product to be packaged and the aesthetic and functional needs of the customer.

SEMI-AUTOMATIC PACKAGING MACHINES

Semi-automatic bell packaging machines are perfect for small and medium productions. They require operator intervention to start the cycle, but still automate the welding and retraction phases, ensuring:

• Maximum process control
• Reduced cycle times
• Adaptability to different types of film
• Ease of use and maintenance
  
  They are ideal for artisanal activities, laboratories, small industries and companies that want a high level of quality without having to invest in complex systems.

AUTOMATIC PACKAGING MACHINES

For higher production needs, there are automatic bell packaging machines, which further optimize the process. The cycle is completely automatic: the operator inserts the product and the machine carries out each phase without further intervention.

The advantages:

• High productivity
• Constant precision
• Savings of time and labor
• Ability to customize sealing and shrinking parameters
  
  Ideal for industrial companies and for companies that package large volumes every day

Main features of bell packaging machines

Both the automatic and semi-automatic versions share some fundamental characteristics:

• Variable dimensions of the bell, to package items of various sizes, from small objects to medium-sized boxes.
• Digital temperature control, for perfect and homogeneous adhesion of the film.
• Compact and robust structure, which adapts to any work environment.
• Integrated internal ventilation, for uniform shrinking.
• Reduced energy consumption, thanks to the efficiency of the heating system.
• Furthermore, many models are designed with particular attention to ergonomics, to ensure ease of use even in intense production contexts.
