Meech offers static generator for shrink-wrapping

Meech International has introduced the Meech Model 992v3 30kV Static Generator to ensure over-wrapping produces perfect seals and reduces overlap to 3-4mm, saving money.

Horizontal flow wrapping, often referred to as shrink-wrapping or overwrapping, uses polyethylene and other shrink films to produce skin-tight packaging.

The film is fed around a forming box, creating a tube.

Products are fed into this tube in a continuous process.

To seal the film, an overlap of 25-35mm of film is required.

Heat sealing seals the overlap.

However, because of tension on the film, the overlap is prone to come apart, making the seal pop open.

This results in a high rejection rate and requires re-wrapping.

To overcome this problem, wider films are used that produce a larger overlap, but this is expensive.

The Meech Model 992v3 30kV Static Generator generates a controlled level of static charge operating in constant current mode.

This static charge will create a temporary bond between the materials.

When installed on a horizontal flow wrapping line, a static charge is generated and directed onto the film with a strategically placed Meech pinning head.

This charge holds the film in place as it moves into the shrink tunnel.

The Meech system is already in use in hundreds of Omori horizontal flow wrapping machines in food companies across China.
