When it comes to selecting the right material for cosmetic hoses, it's crucial to make an informed decision. The appropriate material can affect the durability, effectiveness, and safety of the product. Therefore, it's vital to choose carefully. So, what is the best material to use? There are various materials to consider, and each has its advantages and disadvantages, depending on the intended use. It's essential to consider factors such as the product's consistency, the chemicals involved, and the packaging environment. By carefully analyzing these factors, you can make an educated decision on the most appropriate material for your cosmetic hose.
Cosmetic hose manufacturers produce different types of hoses, including single-layer, double-layer, and five-layer hoses, which vary in terms of their pressure resistance, penetration resistance, and texture. A five-layer hose typically consists of an outer layer, an inner layer, two adhesive composite layers, and a barrier layer. This type of hose provides excellent gas barrier performance, effectively preventing oxygen and odorous gases from infiltrating the contents. Additionally, it prevents the fragrance and active ingredients of the contents from leaking out.
Double-layer pipes are the preferred choice for most applications, while single-layer pipes are often used for lower-end products. The hose diameter can range between 13# to 60#. The length of the hose varies depending on the desired capacity, which can be adjusted between 3ml and 360ml. To maintain a consistent aesthetic, smaller diameters (below 60ml) typically use calibers under 35#, while 100ml and 150ml sizes tend to use calibers between 35# and 45#. For capacities greater than 150ml, a caliber above 45# is required.
Technology-wise, medical hoses can be categorized into round tube, oval tube, flat tube, and super flat tube. While all are widely used, flat tubes and ultra-flat tubes are more complex, resulting in a higher cost. On the other hand, the medical hose industry has released new and more advanced tubes in recent years, which can also drive up the price.
Hose caps come in various shapes including flat caps, round caps, high caps, flip caps, ultra-flat caps, double-layer caps, spherical caps, and lipstick caps. Plastic caps can also be processed in different ways such as bronzing edge, silver edge, colored cap, transparent, oil spray, electroplating, and more. It’s worth noting that the tip cap and lipstick cap usually have inner plugs. The hose cap, which is an injection molded product, is different from the pull tube of the hose. Usually, manufacturers of hoses do not produce the hose covers themselves.
When it comes to some products, filling is necessary before they can be sealed. The sealing process has several options available, including straight sealing, twill sealing, umbrella sealing, star point sealing, and special-shaped sealing. To ensure proper expiration dates, the desired date code must be printed at the end of the process.
There are various types of hoses available for different purposes. These hoses can be made of different materials such as colored, transparent, frosted, or pearl tubes with both matte and glossy finishes. While matte finishes look elegant, they tend to get dirty quickly. A closer look at the tail incision of hoses reveals that if white ink is used for printing, it should be of high quality to prevent peeling, cracking or exposing white marks when folded.
