Industry Pain Points Solved 1. Low Barrier Against Oxygen & Moisture: Conventional PE liner ton bags only provide basic waterproof protection with weak oxygen isolation performance. Sensitive materials are easily oxidized, damp, deteriorated and agglomerated after long-term storage and transportation, resulting in reduced product activity and scrapped batches, which causes huge economic losses. 2. Damage & Material Degradation: Many chemical and electronic materials are sensitive to light and ultraviolet rays. Ordinary transparent or translucent inner films cannot block light effectively. Long-term light exposure will trigger material chemical reactions, leading to color fading, performance degradation and unstable product quality. 3. Low Sealing Performance & External Contamination: Common inner liners are prone to air penetration and dust infiltration. In complex logistics and storage environments, external dust, volatile gas and impurities will pollute high-purity materials, failing to meet the purification and dust-free packaging standards of high-end industries. 4. Anti-corrosion & Anti-aging Ability: Ordinary PE inner films are vulnerable to corrosion by acidic and alkaline chemical materials, and easy to age and crack in high-temperature and harsh environments. Damaged liners cannot protect internal materials, bringing hidden dangers to cargo safety. Core Selling Points 1. Ultra-high Barrier Performance, Anti-oxidation & Anti-deterioration: The aluminum foil composite inner film has dense molecular structure, achieving nearly zero oxygen and water vapor permeability. It completely isolates air and moisture, effectively preventing oxidation, dampness and agglomeration of sensitive materials, and greatly prolongs the shelf life of stored products. 2. Full Light Shielding & UV Resistance: The metallic barrier layer of aluminum foil can block all visible light and ultraviolet rays, thoroughly avoid material performance attenuation and chemical changes caused by light irradiation, and perfectly protect light-sensitive industrial raw materials. 3. Excellent Sealing & Dust-free Protection: The integrated aluminum foil inner lining fits tightly with the outer woven bag, with good overall sealing performance. It effectively resists external dust, volatile impurities and bacterial pollution, meeting the high-standard packaging requirements of dust-free workshops and high-purity material industries. 4. Strong Chemical Corrosion Resistance & High Temperature Resistance: Premium aluminum foil composite material features stable chemical properties, acid and alkali corrosion resistance, and high temperature resistance. It adapts to various harsh storage and transportation environments, no cracking, no peeling, and maintains stable packaging protection performance. 5. Integrated Structure & High Operational Efficiency: Adopts integrated compound forming technology without loose lining displacement. It supports automatic filling, stacking and lifting, saves manual lining installation procedures, improves packaging efficiency, and is compatible with modern automated production lines. 6. Customization & Wide Application Range: Support customized bag type, load capacity, sealing method, inlet and outlet structure. Suitable for battery electrode materials, chemical pigments, pharmaceutical intermediates, food powder, rare earth materials and other high-value bulk materials, covering various high-end industrial packaging scenarios. 7. Stable Quality & High Safety: The aluminum foil inner film has high tensile strength and puncture resistance, not easy to be damaged during handling and transportation. The whole bag is non-toxic, tasteless and environmentally friendly, compliant with international industrial and food-grade packaging safety standards.
