Will stretch liner be a commonly used product in the water cup market in the future?

A long time ago, the processing method of the water cup liner has been introduced at many lengths. Here, I will briefly talk about it. At present, the processing methods of the water cup liner of various water cup factories and water cup brands are mostly two types: tube drawing and stretching. , and there are some special processing methods that I won’t go into details about since they are not very popular.

Because the liner produced by the tube drawing process will have obvious laser welding line marks, it is also called a welded liner by some water bottle factories. This kind of liner has obvious weld marks on the liner like a scar, which affects the quality of the liner. It is beautiful, and some factories have relatively rough welding techniques, and the subsequent processes are not processed in place. Therefore, some drawn tube welding wires on the market will be found to be black or even rusty. Logically speaking, stainless steel will not rust, but If there is laser high-heat welding and no polishing treatment is in place, the high heat will destroy the stainless steel layer, so rust will also occur. These reasons have caused some consumers to resist water cupswith drawn tubes.

In the stretching process, since the inner liner does not use a welding process, the inner liner will be more beautiful and smooth. Consumers think that using such an inner liner will be more reassuring, so most factories are now beginning to use more and more stretching. Process production of water cup liner. However, due to the complexity of the drawing process, low production efficiency and high production difficulty, the price of water cups produced by this process is higher than that of water cups produced by the drawing process, so some consumers who pursue cost-effectiveness will not choose it.

With the improvement of production technology and the popularization of automation, the production cost of the stretching process is also declining. So will the stretching liner process become the main process in the water cup market in the future?

The editor believes that drawing is now the mainstream processing method and is already common in the market. However, it will be impossible to become the only one in the future. The drawing process is also improving, including the current spinning process. The thin technology is more to make up for the shortcomings caused by the tube drawing process. It not only improves the effect of the liner, but also increases the performance of the water cup.
