1. The squeeze tube is divided into single-layer, double-layer and five-layer squeeze tubes, which are different in terms of pressure resistance, anti-permeability and hand feeling. For example, the five-layer tube consists of an outer layer, an inner layer, and two adhesive layers. Barrier layer. Features: It has excellent gas barrier properties, which can effectively prevent the infiltration of oxygen and peculiar smell gas, and prevent the leakage of content fragrance and effective ingredients.
2. Double-layer pipes are more commonly used. Single-layer pipes can be used for medium and low-grade pipes. The diameter of the squeeze tube is more than 13-60 calibers. When a squeeze tube of a certain caliber is selected, different capacity characteristics and capacities are indicated by different lengths. 3ml-360ml can be adjusted at will. For the sake of beauty and coordination, the caliber below 60ml is commonly used. The caliber of 100ml and 150ml is usually 35-45. For the capacity of 150ml, the caliber above 45# is required.
3. In terms of technology, it is divided into round tube, oval tube, flat tube and super flat tube. Flat tube and super flat tube are more complicated than other tubes. They are also new types of tubes in recent years, so the price is correspondingly more expensive.
