Click2ContactKM Packaging has released the K-Peel 4G mono PET lidding film specification, which has a low seal initiation point and is capable of sealing through contamination. The low seal initiation point also makes it compatible with PET trays and it can provide a clean, strong peel for APET and rPET trays. It is also suitable for trays that present sealing challenges because of thickness or available sealing area. The film can provide a clean peel for ambient, chilled or frozen applications and is ovenable. The lower gauge can be used for reducing the thickness of films in production.
