Shrink Wrap Tunnels

Seamless Packaging Perfection: Shrink Wrap Tunnels by PACKMACHINE, Bangalore for Diverse Application Excellence

Shrink tunnels, either double or single chamber, are positioned after a sealing unit in a complete shrink wrapping line. Their purpose is to tightly shrink the plastic film that has been placed around the products in either the bags, sleeves or tubes formed (depending on the style of sealer being used). This is done with the application of heat which reacts with the film to make it shrink down. The use of heat sometimes leads to these machines being called shrink ‘ovens’. Our shrink tunnels can also be supplied individually for a bagging operation.

Roller conveyor systems are deployed for presentation applications, which allows maximum airflow to the underside of the packs for high-quality, consistent results. The rollers rotate throughout in order to transfer the product along, meaning that the pack travels faster than the conveyor itself. This ensures that the underside of the pack is never in constant contact with the belt and prevents markings from being left on the film. This is a clear advantage over cheaper, mesh belt systems. When polythene is being used, we recommend the use of a heavy-duty steel mesh belt which provides pack stability, coupled with under belt and after pack coolers. Our upgraded steel-mesh belts are preferable to tunnel belts that are driven by friction because they will never stretch or need replacing – even after years of production.

We have a range of tunnels to accommodate any speed, any product and any material for a vast array of packaging applications. Harsh environments such as dairies also are accommodated with our stainless steel frame tunnels.

Ideal for any request, but specifically designed for application in the food and pharmaceutical industries, the PACKMACHINE shrink tunnels make impeccable, hygienic and appealing sealed packages.

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.

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.

A model for every packaging requirement

All PACKMACHINE shrink tunnels can be applied to different sectors and production businesses due to their large variety and versatility. If machines from the Digit range are distinguished by their ability to fulfil all different types of packaging requirements, the tunnels from the Twin series are specifically designed to create compact packages.

Wide Shrink Tunnel in Bangalore

Wide Shrink Tunnel

We can offer a range of wide shrink tunnels to complement our wide inline sleeve sealing machines and these are distinct from their regular counterparts in a number of ways. Wide shrink tunnels are required to wrap much larger and much heavier items and so they have a number of specially designed and upgraded features to make them suitable. These include upgraded belts, upgraded drive motors and improved air flow, to achieve the optimum shrinkage around the products.
