Stainless Steel vs Ceramic-Coated Inner Liners

Due to the long history of stainless steel cups, conventional electrolytic stainless steel liners are gradually unable to meet the increasing demand of people. In recent years, a new method of inner liner treatment has emerged - internal spray ceramic inner liner. This article focuses on comparing the advantages and disadvantages of this inner liner with conventional stainless steel inner liners.

The conventional stainless steel liner, which comes into direct contact with food, is made of metal and is typically made of 304 or 316 material. Therefore, when storing flavored beverages such as tea, milk tea, coffee, etc., the stainless steel inner container will affect their original flavor. Legitimate stainless steel cup products can fully comply with food container contact regulations around the world. If it meets the FDA standards in the United States, the KS standards in Japan, and the LFGB standards in Europe. But the increasing demand for products from consumers always tells us that a new process should be developed to solve this problem. So the process of internal spraying a ceramic inner liner emerged.

The big advantage of the internal spraying ceramic technology is that it will not affect the original flavor of the drink at all, and you can taste the pure flavor of the drink. Moreover, due to its ceramic material, residues such as coffee or tea stains can be easily removed with water or neutral detergent. Due to the characteristics of ceramics, ceramic-coated cups can also hold carbonated beverages without worrying about corrosion. With an inner spray ceramic liner, you can better enjoy the fun of chilled carbonated drinks.

Of course, everything has two sides, and the ceramic inner liner sprayed inside does not mean that there are no shortcomings. Due to the rigid and integrated nature of ceramics, their drop resistance is not as good as that of traditional stainless steel liners. Stainless steel cups that fall off in daily life may just be deformed. But if the cup with the ceramic spray inside falls off, the entire ceramic liner may shatter. Therefore, compared to cups with stainless steel inner liners, cups with ceramic spray inside need to be used more carefully in daily life to prevent falling. Our manufacturer's suggestion is to purchase additional sponge or silicone cup covers, which can effectively reduce the damage caused by falling cups. At the same time, attention should be paid to daily use. If the ceramic inner liner falls off, the flavor of the beverage may be affected to some extent, and carbonated beverages can no longer be stored. Daily use of carbonated beverages can corrode the stainless steel liner.

The above are some suggestions we have given as a professional stainless steel cup factory. The new technology has arrived, which can better maintain the flavor of beverages and is not afraid of corrosion from carbonated drinks. Why don't you give it a try!
