Cosmetic tubes are hygienic and convenient to use, bright and beautiful in surface color, economical and convenient, and easy to carry. Even after high-strength extrusion around the body, they can still return to their original shape and maintain a good appearance. Therefore, it has been widely used in the packaging of cream cosmetics, such as facial cleanser, hair conditioner, hair dye, toothpaste and other products in the cosmetics industry, as well as the packaging of creams and pastes for topical drugs in the pharmaceutical industry.
1. Tube includes and material classification
Cosmetic Tube generally includes: hose + outer cover. The hose is often made of PE plastic, and there are also aluminum-plastic tubes, all-aluminum tubes, and environmentally friendly paper-plastic tubes.
*All-plastic tube: The whole tube is made of PE material, first pull out the hose and then cut, offset, silk screen, hot stamping. According to the tube head, it can be divided into round tube, flat tube and oval tube. Seals can be divided into straight seals, diagonal seals, opposite-sex seals, etc.
*Aluminum-plastic tube: two layers inside and outside, the inside is made of PE material, and the outside is made of aluminum, packaged and cut before coiling. According to the tube head, it can be divided into round tube, flat tube and oval tube. Seals can be divided into straight seals, diagonal seals, opposite-sex seals, etc.
*Pure aluminum tube: pure aluminum material, recyclable and environmentally friendly. The disadvantage is that it is easy to deform, just think about the toothpaste tube used in childhood (post-80s). But it is relatively unique and easy to shape memory points.
2. Classified by product thickness
According to the thickness of the tube, it can be divided into single-layer tube, double-layer tube and five-layer tube, which are different in terms of pressure resistance, penetration resistance and hand feeling. Single-layer tubes are thinner; double-layer tubes are more commonly used; five-layer tubes are high-end products, consisting of an outer layer, an inner layer, two adhesive layers, and a barrier layer. Features: It has excellent gas barrier performance, which can effectively prevent the infiltration of oxygen and odorous gases, and at the same time prevent the leakage of the fragrance and active ingredients of the contents.
3. Classification according to tube shape
According to the tube shape, it can be divided into: round tube, oval tube, flat tube, super flat tube, etc.
4. The diameter and height of the tube
The caliber of the hose ranges from 13# to 60#. When a certain caliber hose is selected, different capacity characteristics are marked with different lengths. The capacity can be adjusted from 3ml to 360ml. For the sake of beauty and coordination, 35ml is commonly used below 60ml For the caliber below #, 100ml and 150ml usually use 35#-45# caliber, and the capacity above 150ml needs to use 45# or above caliber.
5. Tube cap
Hose caps have various shapes, generally divided into flat caps, round caps, high caps, flip caps, ultra-flat caps, double-layer caps, spherical caps, lipstick caps, plastic caps can also be processed in a variety of processes, bronzing edges, Silver edge, colored caps, transparent, oil-sprayed, electroplated, etc., tip caps and lipstick caps are usually equipped with inner plugs. The hose cover is an injection molded product, and the hose is a pull tube. Most hose manufacturers do not produce hose covers themselves.
6. Manufacturing process
•Bottle body: the tube can be colored tube, transparent tube, colored or transparent frosted tube, pearl tube, and there are matte and glossy, matte looks elegant but easy to get dirty. The color of the tube body can be directly produced by adding color to plastic products, and some are printed in large areas. The difference between colored tubes and large-area printing on the tube body can be judged from the incision at the tail. The white incision is a large-area printing tube. The ink requirements are high, otherwise it is easy to fall off and will crack and show white marks after being folded.
•Bottle body printing: screen printing (use spot colors, small and few color blocks, the same as plastic bottle printing, need color registration, commonly used in professional line products) and offset printing (similar to paper printing, large color blocks and many colors , Daily chemical line products are commonly used.) There are bronzing and hot silver.
7. Tube production cycle and minimum order quantity
Generally, the period is 15-20 days (starting from the confirmation of the sample tube). Large-scale manufacturers usually use 10,000 as the minimum order quantity. If there are very few small manufacturers, if there are many varieties, the minimum order quantity for a single product is 3,000. There are very few customers' own molds, their own molds, most of them are public molds (a few special lids are private molds). There is a deviation of ±10% in this industry between the contract order quantity and the actual supply quantity.
