We offer solutions for effective chemical resistance and aroma protection which are essential for maintaining quality in household and grocery packaging.
Major film structure
PET/OPA/LLDPE (general)
OPA/met PET/LLDPE (focused on aroma barrier and quality preservation)
Application trend
A choice of film structure is critical to provide an effective barrier against especially for the fragrance components in detergent.
Since detergent ingredients like surfactants and fragrances can penetrate films and degrade the adhesive, it may lead to softening or hydrolysis, eventually causing content-induced delamination. It is key to select an optimal adhesive such as a chemical-resistant adhesive.
The shift toward larger refill pouches has increased the static load placed on heat sealed areas. To withstand vibrations during transport and stacking loads, strict process management is requires to maximize bond strength, including optimized seal width design and regouros control of aging times after lamination.
