Juice drinks are highly susceptible to the effects of oxygen, light, and moisture, which can accelerate oxidation, nutrient loss, and flavor deterioration. Compared to plastic or low-grade metal caps, electrolytic galvanized tin sheet provides unparalleled barrier protection, locking in the freshness of juice from production to retail. Here are the reasons why our 211 # 65mm tin plate bottom cover has become the preferred choice for global juice can manufacturers:
Long term preservation: The natural tin coating on the lid neutralizes residual oxygen in the can during the sealing process, reducing oxidation and preserving the vitamin C, natural flavor, and bright color of fruits and vegetables in the juice. This oxygen absorption effect significantly extends the shelf life without adding additional preservatives, which is in line with the trend of cleaning labels favored by consumers.
Tight leak proof seal: The precisely machined 65mm diameter and standard 211 # size ensure a perfect match with compatible juice can bodies. The double seam structure forms a sturdy airtight closure, preventing leakage, spillage, and contamination during storage, transportation, and stacking processes. Even after experiencing temperature changes and rough handling, the seal remains intact, protecting every batch of juice.
Food grade and compliance: Our bottom cover is made of food grade tin plate and BPA free inner coating, complying with FSSC 22000, ISO 9001, and FDA food contact regulations. They are non-toxic, corrosion-resistant, and will not infiltrate harmful chemicals into acidic juice products, ensuring consumer safety and making your brand compliant with global regulations.
Durable and sturdy: The rigidity of tin plates is much higher than that of thin aluminum or plastic covers, which can effectively prevent dents, deformations, and damages during canning processing and logistics. This durability reduces product waste, lowers operating costs, and keeps canned juice neat and attractive on shelves.
Wide machine compatibility: The standardized 211 # 65mm design is suitable for most automatic juice canning production lines, achieving smooth high-speed production without frequent adjustments or shutdowns. It is suitable for all types of canned fruit juices, including orange juice, apple juice, mango juice, vegetable blends, and functional drinks.
Low quality can lids often lead to problems such as short shelf life, can leakage, and low production efficiency for juice producers.
