Case Studies & Tech Support

Stretching break is a common BOPP film defect that can cause production stops, material loss and unstable film quality. Learn the main causes, quick diagnosis steps and how to reduce breakage during stretching and downstream packaging lamination.

Low corona treatment can reduce the surface energy of BOPP film and make coating, printing and lamination more difficult. Learn the main causes, quick diagnosis methods and how to improve corona treatment stability.

Streaks are a common BOPP film defect that appear as continuous bright or dark lines in the machine direction. Learn the main causes, quick diagnosis steps and their impact on packaging lamination and final film appearance.

Thickness variation is a common BOPP film defect that can affect coating, lamination, appearance and converting performance. Learn the main causes, quick diagnosis steps and how proper production control helps maintain film consistency.

Fish eyes are small hard or gel-like defects found in BOPP film. They can affect appearance, coating, printing and converting performance. Learn how to identify the problem, find the likely cause and reduce the risk through proper production control.
