1. Skin care hoses are divided into single-layer, double-layer, and five-layer tubes, each of which is different in terms of pressure resistance, anti-seepage and hand feeling. For example, a five-layer tube consists of an outer layer, an inner layer, two adhesive layers, and a barrier layer.
Features: It has excellent gas barrier properties, which can effectively prevent the entry of oxygen and odorous gases, and at the same time prevent the aroma of the contents and the leakage of active ingredients.
2. Double tubes are more commonly used, and those belonging to the middle and low grades can also be used in a single layer. The caliber of the hose is 13#-60# multi-caliber. When choosing a hose of a certain caliber, different lengths show different capacity characteristics, and the capacity can be adjusted arbitrarily between 3ml-360ml. In order to be beautiful and harmonious, the caliber below 60ml is 35#, and the caliber of 100ml and 150ml is usually 35#.
3. In terms of process, it is divided into round tube, oval tube, flat tube and ultra-flat tube. The technology of flat tube and ultra-flat tube is more complicated than other tubes, and it is also a new type of tube that has appeared in recent years, so the price is correspondingly higher.
4. Skin care product tubes have various shapes. Generally, they can be processed through various processes like flat caps, round caps, high caps, flip caps, super flat corner caps, double-layer caps, spherical caps, lipstick caps, and plastic caps. Hot stamping, silver edge, colored sleeves, transparent, oil spray, electroplating, etc. Pointed sleeves and lipstick sleeves usually have inner plugs. Hose caps are injectables, hoses are pull tubes, and most hose manufacturers do not make hose caps.
5. Some products need to be filled and sealed. The seals are roughly divided into straight seals, silk seals, umbrella seals, star point seals, and special-shaped seals. When sealing, it is required to print the necessary date on the seal code.
6. Skin care product tubes can be made into colored tubes, transparent tubes, colored or transparent frosted tubes, and pearlescent tubes. In addition, there is a difference between a mat and a gloss. The mat looks elegant, but it gets dirty easily. The difference between the colored tube and the large-area printing of the tube can be judged from the cutout at the tail. The ones with white cutouts are large-area printing tubes, which have high requirements for ink. Otherwise, it is easy to fall off, break or appear white marks.
