Efficient Shrink Tunnels for Seamless Packaging: PACKMACHINE, Bangalore's Advanced Solutions for Wrapping and Sealing Perfection

The PACKMACHINE shrink tunnels represent the most classic and efficient solution to package products with shrink film. Their operation is simple but extremely effective: inserting a packaged product into the oven causes a reaction of the hot air on the transparent film, making it shrink and thus adhere perfectly to the contents of the package.

The tunnels guarantee an impeccable result: the packages are sealed, are practical and also pleasant to see since a shiny, soft film is used. The shrink film is made of polyolefin, which differs from PVC for its higher resistance to tearing once processed, and for the decreased impact on energy and the environment: when sealing, the polyolefin does not generate toxic fumes.

Shrink tunnels are temperature controlled environments used to tighten shrink film that has been applied by a shrink wrapper around products. Conveyor systems move packages through the oven, allowing for an even application of heat. Conveyors are made from either large rollers or Teflon mesh belts for added stability.

Shrink tunnels are available in single and dual chamber formats. Single chamber shrink tunnels are perfect for lower packaging volumes that run a lower pack speeds. Dual Shrink Tunnels are great for faster packaging speeds. Allowing for a more controlled shrink with variable chamber temperatures.

PACKMACHINE shrink tunnel: hygiene, speed, flexibility and specialisation

Our shrink tunnels have two distinct features that stand out: the advanced technological level and appealing aesthetic design. However, besides these obvious qualities, the machines also guarantee other advantages:

• Having been designed with specific focus on the end customer, the tunnel can be easily applied to the pharmaceutical and food sectors: in fact, most of them are made using stainless steel or Steel IT, which is resistant to wear, corrosion and chemical and atmospheric agents. In short, maximum hygiene.
• Numerous models, especially the Twin series, are designed to produce a large number of packages, in small sizes and at high speed: also ideal for smaller packaging requirements.
• Despite being suitable for small business, the advanced technology of the machines enables them to be incorporated in large production lines, in medium-large industrial environments without any problems.
• As a result of ensured thermal insulation from the chamber for shrinking, all tunnels boast of high passage and shrinking speed, creating a large number of pieces per minute. All this does not compromise the quality since each package comes out from the tunnel perfectly sealed and adherent to the product, protected by a shrink film resistant to tears.

What Are Heat Tunnels For Shrink Packaging?

A shrink tunnel (also commonly known as a heat tunnel) is a metal tunnel that sits above or is built around a conveyor, often being fed from a heat-sealing machine.

The tunnel has a heating element that heats the film as they move through the machine. Your products are conveyed through the tunnel and are cloaked with loosely fitting shrink film.

When your products move past the heating elements, the film shrinks uniformly around the items as they are exposed to the heat.

Our available machines can be combined with sealing machinery and are perfect for shrinking a wide range of films, from the lightest polyolefin to the toughest polyethylene films.

Benefits Of Using Shrink Tunnels In Your Packaging Process

---

Protection

A shrink Tunnel heats the shrink film to encase your product in a tight, clear, sealed package

Consistency

Heat is distributed evenly around the packaging, allowing the film to shrink evenly with consistency

Flexibility

The product can be sent through a tunnel with a variance of heat and speed depending on product requirements

Customization

Tunnels can be designed to fit specific applications

Specialization

Cooling zones can be added for low-temperature food applications

Safety

Emergency stop switch if an emergency occurs during operation and main breaker switches designed to trip before electrical draw exceeds carrying capacity
