Technical Challenges in FFS (Form-Fill-Seal) Heavy-Duty Packaging

Poor Anti-Slip (Anti-Skid) Performance
FFS bags may suffer from stacking instability during high-pile storage or transportation due to insufficient coefficient of friction (COF) and stiffness in traditional films. Panteto adding fibrous inorganic fillers and dispersing agents to enhance surface friction and mechanical strength.
Mechanical Strength & Impact Resistance Heavy-duty packaging must withstand high stress and impact** during handling and transport. Conventional woven or laminated bags may fail under load. FFS films use multi-layer co-extrusion (e.g., mLLDPE for toughness, HDPE for stiffness) to enhance durability.
Air Venting vs. Sealing Integrity** For powdered or granular materials (e.g., PVC, PP), trapped air can cause bag bulging, but traditional venting holes may lead to leakage. Panteto use special air exausted vacuum-assisted sealing instead of vents to maintain strength.
