The interlocking structure of stackable tea tins treats each layer as part of a unified mechanical system rather than an independent container. We first determine the tea-tin diameter, number of layers, fill weight, opening mechanism, and required stacking height. Next, we design the geometric fit between the upper and lower cans, including shoulder positioning, bottom […]

Developing new molds for custom food tins starts with the product, not the mold-making process. At TSING, we first confirm the tin’s required dimensions, shape, lid structure, intended food use, internal layout, and exterior decorative details. We then translate the approved design concept into seven stages: Custom Sample Drawing → Mold Structure Drawing → 3D […]

The SCA notes that oxygen is the main factor causing roasted coffee to deteriorate (lose flavor), and that storage humidity also affects coffee quality. Therefore, when selecting a coffee can, the seal design is crucial. Two common seal designs are the “double-lid coffee tin” and the “gasket-sealed coffee tin.” The double-lid design creates two barriers […]

Many customers ask us, “How should we choose the custom tea tin sizes for 100g, 250g, and 500g of tea?” Our answer is: Choosing a custom tea can size based solely on weight may result in an inaccurate package size. Two types of tea that both weigh 100 grams may have vastly different volumes. Research […]

Two products might use metal cans of identical dimensions, tinplate thickness, and even exterior printing, yet still need to meet different specifications for food contact tin packaging. The reason is simple: oily and acidic foods determine the specific resistance properties required for the inner surface. Acidic foods subject the packaging to an environment that places […]
