What are the core raw materials of canned food?

Choosing tin-plated plate as the core material of canning is mainly because it has several irreplaceable advantages:

• Extreme freshness preservation ability: Tin-plated plate can be like a "golden bell cover", completely isolating the food in the jar from the air, moisture and light outside, preventing oxidation and bacterial growth, so as to achieve an ultra-long shelf life.

• Absolute safety and security: The tin layer and steel base are very stable and will not react chemically with acidic or alkaline food, ensuring food safety.

• Sufficient structural strength: Compared with aluminum, steel is stronger, which can withstand the sterilisation process of high temperature and high pressure after food canning, and is also more pressure-resistant and not easy to deform.

• Excellent processing performance: It can be easily stamped, welded and printed, and can make various shapes and exquisite patterns.
