The better alternative: plasma pretreatment for broad packaging film webs

Plastic film is typically produced using blown film and film stretching processes. The corona process is often used to pretreat these films for printing and finishing processes, but this poses its own problems. The corona process achieves only limited surface tension that declines significantly after just a few weeks in storage. And as an outcome of the process, even minor contamination on pretreatment rollers can result in punctures on the reverse side of the material.
 Plasma treatment of packaging film webs
 Secure ink bonding on plastic film packagings

Plasmatreat has developed two especially reliable techniques for pretreating packaging film with typical web widths of 2.2 to 8 meters:

  • Plasmatreat Glow Plasma achieves especially cost-effective, durable surface activation at the highest level. Surface tensions of up to 64 mN/m are reached in the process.
  • Openair® Plasma treatment with patented sheet die technology ensures absolutely single-sided pretreatment of plastic packaging films. Punctures on the reverse side are impossible; and the adhesion values show exceptional long-term stability. Openair® plasma’s advantages are especially evident at high processing speeds and when recycled materials are used.
