Causes Analysis of Delamination in Retort Pouches
Delamination in retort pouches manifests in interface damage at three key layers: the inner film/adhesive, adhesive/ink, and ink/outer film. It can also occur as cohesive failure within the adhesive layer or the ink layer. When delamination is minor, it appears as stripe-like separation in the stressed areas of the packaging, or the pouch can be easily peeled or torn apart by hand

Cause Analysis of Puncture – Example of three-Side Seal Pouch
Puncture refers to a through-hole or crack in the packaging material, particularly during the production of three-side seal pouch, caused by external force or pressure. This defect significantly affects the packaging integrity, leading to issues such as air leakage during inflation, failure to achieve proper vacuum sealing, and leakage in the containment of liquid products.

Cause Analysis of Poor Heat Seal Strength
- Impact of Heat Seal Materials
The type of heat seal material affects its seal strength. For example, PP, PE, and EVA have different heat seal strengths. Even within the same type of film, products made with different polymerization methods exhibit varying heat seal strengths. Factors such as material thickness and uniformity also influence the seal strength.
