502# 127mm & 603# 153mm Tinplate Bottom Ends

Commercial large capacity pickle jars are designed for bulk wholesale and long-term commercial storage, unlike small retail packaging. High salt and high acidic components will gradually corrode metal packaging, while industrial high-temperature sterilization and cross-border transportation bring continuous compression and pressure. Low quality bottom lids often cause deformation of the can bottom, minor leaks, and spoilage of pickled vegetables. This makes heavy-duty, salt resistant, and sterilization safe tinplate bottoms essential for commercial fermented vegetable packaging.

The 502#27mm tinplate bottom end is a practical medium-large caliber option for standard commercial pickle cans. Made of premium food-grade tinplate with professional anti-corrosion inner coating, it effectively withstands long-term erosion from salty and acidic fermented vegetables. It fits most mainstream catering-size cans for pickled mustard, sauerkraut and marinated side vegetables perfectly.

With precise caliber consistency, this standard bottom end works seamlessly with fully automatic can seaming equipment, ensuring stable and tight seams during mass production. Its reinforced structure easily handles industrial sterilization pressure and stacked warehouse storage, effectively preventing base bulging, rust spots and liquid leakage. It remains the most cost-effective choice for daily bulk commercial pickled vegetable packaging.

The 603# 153mm tinplate bottom end is a heavy-duty large-caliber solution, tailored for extra-large pickle cans used by central kitchens, restaurant chains and large food manufacturers. Featuring thicker tinplate and optimized structural reinforcement, it supports heavier canned fermented vegetables and withstands rigorous industrial high-temperature sterilization workflows.

Compared with regular-size lids, this large-caliber bottom cover delivers superior overall structural stability for oversized cans. Its excellent barrier property locks out external oxygen and moisture, preventing pickled vegetables from discoloration, off-flavors and deterioration during long shipping cycles and extended shelf storage. It is the ideal packaging accessory for suppliers focusing on large-batch catering condiment distribution.

These two tinplate bottom end sizes cover medium and large-capacity commercial fermented food packaging needs, suitable for sauerkraut, pickled mustard, seasoned radish and various pickled side dishes. They are widely used for restaurant bulk ingredients, catering wholesale, cross-border export and large-scale industrial canned food production.

A professional matching bottom cover is crucial to ensure the quality and shelf life of commercial canned pickles. 502 # 127mm and 603 # 153mm tinplate bottom covers provide targeted anti-corrosion, pressure resistance, and stable sealing performance, perfectly adapting to the harsh production and storage conditions of high salt fermented foods. With reliable quality and excellent cost-effectiveness, they are the ideal long-term packaging solution for global food and beverage manufacturers and wholesale distributors.
