Tight Sealing Prevents Powder Leakage, Three-Side Seal Bags Protect Granule & Powder Quality
2026/06/08
Powder and granule products require extremely high packaging tightness. Fine powder easily absorbs moisture, agglomerates and mixes with peculiar odors. Tiny sealing gaps will cause powder leakage, dust ingress and dampness. It ruins product appearance, causes material loss and downgrades user experience.
Instant coffee, meal replacement powder, protein powder and herbal granules are high-precision powder products. They are highly sensitive to moisture and air oxidation. Damp agglomeration directly reduces product activity and taste. Ordinary bags have low sealing precision, easily causing leakage, bag breakage and deterioration after mass packaging.
Three-side seal pouches adopt integrated three-sided heat pressing technology. Thick and tight sealing edges completely avoid fine powder leakage. Wrinkle-free flat bag bodies match high-speed automatic filling equipment. They ensure high production efficiency and stable sealing qualification rate for standardized powder production.
The high-barrier composite structure blocks external moisture and oxygen effectively. It prevents powder damp agglomeration, oxidation and flavor change. It keeps powder fine and dry, retaining product nutrition and efficacy for a long time. The thin and flat bag body saves storage space and resists extrusion damage during transportation.
The double-sided high-definition printing area clearly displays product formulas, efficacy and brand information. It delivers neat and unified terminal display and exquisite product texture. The safe and compliant material fits food and health powder packaging. With high-precision sealing, leak-proof and mass-production compatible performance, three-side seal bags are ideal for powder and granule product packaging.
