A High Barrier Film for a flat-bottom PE pouch must support the pack's shape as well as its contents. A stiff incoming web does not guarantee that a filled bag will stand correctly.
Cailong's High Barrier Film portfolio includes water-based coated MDOPE, listed as an outer print web for flat-bottom bags. The page identifies stiffness and printability alongside coating-dependent barrier.
Observe filled packs at the intended fill weight and headspace. Record whether the side wall bows, a gusset folds inward or the base seal distorts. These patterns call for different adjustments.
Coated MDOPE / PE sealant is a candidate for evaluation. The outer web carries print and support; the sealant forms the closures. Confirm directional stiffness and base dimensions before simply increasing total gauge.
Send Cailong the panel layout, gusset depth, fill weight and standing-pack photographs to define a useful MDOPE trial.
