Material Characteristics
– Tinplate is cold-rolled thin steel plate with tin plating on both sides. The steel provides good formability and high strength, while tin plays a role in preventing corrosion and rusting. The combination of the two endows it with properties such as corrosion resistance, non-toxicity, high strength, and good ductility, laying the foundation for it to be a safe packaging material.
– Tinplate has the property of being opaque to light, which can completely block out light and prevent food from deteriorating due to exposure to light, thus providing a stable storage environment for food and helping to maintain the nutritional components and quality of food.
Good Sealing Performance
– Tins or cans made of tinplate have excellent sealing performance. They can effectively prevent the intrusion of air and moisture, preventing food from spoiling due to oxidation and moisture absorption, thereby prolonging the shelf life of food and maintaining its freshness and taste.
– The good sealing performance can also prevent the aroma of food from escaping and avoid the infiltration of external odors, ensuring the original flavor of food.
Safe Inner Coating
– The inner coating of tinplate usually adopts non-toxic food-grade coatings, such as food-grade epoxy resin or phenolic resin. These coatings comply with relevant food safety standards, can prevent direct contact between iron and food, avoid food contamination or oxidation reactions, and further ensure the safety of food.
Controllable Production Process
– During the production process, strict controls are imposed on various links such as the selection of raw materials, processing techniques, and quality inspection of tinplate to ensure that the produced tinplate meets food-grade standards and does not contain substances harmful to human health.
– The production workshops are usually kept clean and dust-free to avoid contamination of tinplate by dust, bacteria and other pollutants. Moreover, each tinplate product will be carefully inspected before packaging to remove defective or contaminated products.
Recyclability
– Tinplate is a recyclable material, which meets the requirements of environmental protection. It can be recycled after use, reducing the pollution of waste to the environment and conforming to China’s strategic principle of sustainable development.
