Strong Acid and Oil Resistance for Complex Food Formulas
Most commercial sauces, pastes, and pickled foods contain strong acid, grease, and fermented ingredients that easily corrode ordinary metal lids over storage time. The 99mm easy open end adopts upgraded food-grade anti-corrosion inner coating, specially formulated for heavy-duty condiment packaging. It effectively resists long-term erosion from tomato paste, chili sauce, marinades, and various seasoned pastes, preventing coating peeling, rust spots, and flavor contamination. This stable chemical tolerance ensures consistent food safety throughout the entire shelf life.
Retort-Safe Performance for Industrial Sterilization
Industrial canned food production relies on high-temperature retort sterilization to achieve long shelf-life standards. Many large-diameter lids are prone to warping, blistering, and seam failure under high heat and pressure. Manufactured with premium tinplate and mature heat-curing technology, the 99mm tin EOE maintains stable physical structure after standard sterilization processes. It delivers zero deformation and intact sealing performance, fully meeting strict production requirements for exported and commercially distributed canned foods.
Precision Double Seam Structure for Zero-Leakage Sealing
Featuring precise dimensional tolerance and uniform crimping performance, the 99mm easy open end fits perfectly with automatic high-speed seaming equipment. The tight double-seam structure effectively blocks external oxygen, moisture, and dust, avoiding leakage, oxidation, and flavor deterioration. Whether used for thick pastes, semi-liquid sauces, or large-capacity preserved foods, it maintains excellent airtightness during long-term storage and cross-border logistics.
