How to choose a high-quality tea tin can?

This article systematically analyzes the key points of purchasing tea tin cans from the dimensions of sealing, material, design, and supplier screening, helping you find an ideal tea set that combines practicality and beauty.

1. Material is the basis of quality

①. Purity determines safety

High-quality containers must use food-grade pure tin (purity ≥ 99.9%) to avoid heavy metal pollution. The composition can be confirmed through the test report. Inferior alloys are easy to oxidize and may release harmful substances.

②. Thickness affects durability

It is recommended to choose a forged tin material with a thickness of 0.23-0.28mm for the can body. Too thin and easy to deform, too thick will increase the cost. Comparing the cross-section processes of different brands, the edges must be free of burrs and the welding points must be uniform.

2. Process details reflect professionalism

①. Sealing structure design

Focus on checking the fit of the lid and the smoothness of the inner wall. High-quality products often use double-layer buckles or silicone rings to enhance airtightness. You can test on-site whether there is air leakage after shaking after closing.

②. Surface treatment technology

Traditional crafts such as hand-engraving and relief can enhance the artistic value, but it is necessary to ensure that the pattern has no sharp corners. Modern laser engraving is suitable for mass customization, and it is more reliable to choose a manufacturer with proofing services.

3. How to select reliable tea tin cans suppliers

①. Qualification and reputation verification

Preferentially choose manufacturers with ISO certification and food container production qualifications, and understand the actual service level through industry exhibitions or customer cases. Avoid OEM distributors without independent factories.

②. Customized service flexibility

From capacity size to brand LOGO inlay, professional factories should provide personalized solutions. Confirm the minimum order quantity, construction period and after-sales terms during communication. Small batch trial orders can reduce cooperation risks.
