Specifications include a 21mm outer diameter and a 70mm total length. The tube features a clean, straight-cylinder design without surface patterning, conveying a sense of orderly uniformity. The 0.4mm wall thickness ensures high resistance to deformation under pressure. The top cap supports high-precision custom logo application via screen printing or stamping, offering a spacious, flat surface ideal for showcasing brand identity.
Ideally suited for unisex cosmetics, professional contouring sticks, large-format moisturizing lip balms, and "clean beauty" brands. Its understated silver appearance also makes it an excellent choice for premium men's skincare lip products.
Issue: Does the matte silver finish look too plain on a large-diameter tube?
Solution: We recommend using high-contrast colors (such as deep black or royal blue) for the logo on the top cap, or employing deep stamping to create physical shadows that leverage the aluminum's natural depth and add visual dimension.
Issue: Does the 0.4mm wall thickness make the product too heavy?
Solution: While the weight is slightly higher, this is a key selling point for premium aluminum packaging, conveying the "substance" and "luxury feel" that consumers value.
During the filling process for large-diameter tubes, ensure the product formula cools evenly to prevent shrinkage voids caused by excessive temperature differences between the center and the edges. Given the high surface smoothness, the production environment must be strictly controlled for dust to prevent the formation of microscopic particles prior to the plating process.
Outer diameter: 21mm
Total length: 70mm
