Advantages of tinplate packaging: 1. Excellent anti-corrosion performance 2. Good strength and toughness 3. Excellent airtightness and freshness 4. Recyclability and environmental protection 5. Excellent printing and decoration effects 6. Processing flexibility

The common manufacturing material for cookie tin packaging is tinplate, which not only has good mechanical strength and corrosion resistance, but also can provide excellent decorative effects for the can body.

Factors affecting the quality of tinplate: 1. The quality of the base steel plate 2. The uniformity and thickness of the tin plating layer 3. The bonding strength of the tin layer 4. Surface finish 5. The purity and tin damage of the tin layer

if the food in the can is highly acidic or the food is stored for too long, in some extreme cases, tin may dissolve in trace amounts. Even so, the amount of tin dissolved is usually very small and not enough to pose a threat to human health.

The main uses of electrolytic tinplate: 1. Recycling and purification of metallic tin 2. Recycling and reuse of iron substrates 3. Providing high-quality surface treatment processes 4. Environmentally friendly treatment of waste tinplate 5. Application in metal recycling 6. Reducing energy consumption 7. Producing high-purity tin products 8. Prolonging resource life and reducing mineral mining

Tinplate packaging refers to packaging containers made of tin plate as the main material. Tin plate is a metal composite material made of tinplate on the surface of low-carbon steel plate, usually consisting of a steel base material and a tin-plated layer.

One of the common tinplate coated problems: pinholes Pinholes are an extremely common problem in the coating process. The Pinholes not only affects the appearance of product, but also affect the resistance to sterilization for beverage cans and other sterilization cans.
