Cosmetic tube packaging materials generally include the main container and auxiliary materials

The packaging materials for costumes generally include the main container and auxiliary materials.

The main containers generally include: plastic bottles, glass bottles, hoses and vacuum bottles.

Auxiliary materials generally include: color boxes, intermediate boxes, and middle boxes.

I. Plastic bottles

The materials of plastic bottles are generally PP, PE, K material, AS, ABS, acrylic, PET, etc.

2. Generally, for containers with thick walls in the cosmetic category, such as cream bottles, bottle caps, bottle stoppers, gaskets, pump heads, and dust covers, injection molding is adopted. PET blow molding is a two-step process, the tube preform is injection molded, and the product packaging is blow molding. Other containers with thinner walls, such as emulsion bottles and washing bottles, are blown bottles.

3.PET material is an environmentally friendly material, featuring high barrier properties, light weight, non-breakability, chemical resistance, and extremely high transparency. It can be made into pearlescent, colored, magnetic white, and transparent colors, and is widely used in filling gel water. The bottle mouths are generally standard 16#, 18#, 22# and 24# diameters and can be used in conjunction with pump heads.

4. Acrylic materials are injection-molded bottles with relatively poor chemical resistance. Generally, they cannot be directly filled with paste. An inner liner is required for separation. The filling should not be too full to prevent paste from entering the space between the inner liner and the acrylic bottle, thus avoiding cracking. During transportation, the packaging requirements are relatively high because scratches are particularly noticeable. They have high transparency and a very thick wall visually, but the price is relatively high.

5. AS and ABS: AS has better transparency than ABS and better toughness.

6. Mold development cost: Blow molding molds generally cost between 1,500 and 4,000 yuan (the actual price is subject to the purchase quotation, the same below), while injection molds usually range from 8,000 to 20,000 yuan. Molds made of stainless steel are more expensive than those made of alloy, but they are durable. The number of molds produced at one time depends on the output demand. If the output is large, molds that produce four or six at a time can be chosen. Customers can decide for themselves.

7. The order quantity is generally 3,000 to 10,000 units. You can customize the color. Usually, the original color matte and magnetic white are the main colors, or pearlescent powder can be added for effect. Although the bottles and caps are made with the same color masterbatch, sometimes due to the different materials used for the bottles and caps, the color may vary slightly.

8. Screen printing can be done with regular ink or UV ink. UV ink has a better effect, with gloss and a three-dimensional effect. Before production, a plate should be made to identify the color. The screen printing effect may vary on different materials.

9. The processing techniques such as gold and silver hot stamping differ from those of gold powder and silver powder. Hard materials and smooth surfaces are more suitable for gold and silver hot stamping. Soft surfaces have poor hot stamping effects and are prone to falling off. The luster of gold and silver hot stamping is better than that of gold and silver printing.

10. For silk-screen film, a negative film should be produced, with the image and text effects being black and the background color being transparent. For gilding and silvering processes, a positive film should be produced, with the image and text effects being transparent and the background color being black. The proportion of text and images should not be too small or too fine; otherwise, the printing effect will not be achieved.

11. Bottle caps are generally equipped with inner gaskets, pull caps, inner stoppers, and very few are provided with small spoons or droppers. The primary considerations for this are their sealing performance and ease of use.

12. The production cycle is relatively moderate, approximately 15 days (the actual date is based on the purchase diameter, the same below). For cylindrical bottles with silk-screen printing, it is calculated as single-color, while for flat bottles or irregular-shaped bottles, it is calculated as two-color or multi-color. Generally, a first silk-screen printing screen plate fee or fixture fee is charged. The unit price of silk-screen printing is generally 0.08 yuan to 0.1 yuan per color, and the price of the screen plate is 100 to 200 yuan per style. The fixture is about 50 yuan each.

Ii. Glass Bottles

Glass bottles used in cosmetics are primarily classified into several categories: skin care products (creams, lotions), perfumes, essential oils, and nail polish. They have relatively small capacities, and those larger than 200ml are rarely used in cosmetics.

2. Glass bottles are further classified into wide-mouthed bottles and narrow-mouthed bottles. Solid pastes are generally stored in wide-mouthed bottles, which are preferably equipped with aluminum foil caps or plastic caps. The bottle caps can be used for color spraying and other purposes. Emulsions or water-based pastes are generally bottled in narrow-mouthed bottles and it is advisable to use pump heads. Attention should be paid to preventing the springs and balls from rusting. Currently, most pump heads are equipped with glass beads. Generally, the material should be inspected and tested for application. If a cap is used, an inner stopper should be provided. For water-based pastes, small holes and inner stoppers should be used. For thicker emulsions, large holes and inner stoppers should be used.

3. Glass bottles are made of a variety of materials, come in many shapes, have rich processing techniques, and are distributed in a diverse way with bottle caps. Common bottle shapes include cylindrical, oval, flat, rhombic, conical, etc. Manufacturers often develop a series of bottle shapes. The bottle body is made with various techniques such as spraying, transparent, frosted, semi-transparent color matching, silk-screen printing, hot stamping with gold or silver.

4. Screen printing: There are generally two types of screen printing on glass bottles. One is high-temperature ink screen printing, which is characterized by being less prone to color fading, having a relatively dull color, and the purple color adjustment being difficult to achieve. The other is low-temperature ink screen printing, which has a brighter color and higher requirements for ink; otherwise, it is prone to falling off. Also, attention should be paid to bottle disinfection.

5. The cost of spraying is generally an additional 0.5 to 1.1 yuan per item, depending on the area and the difficulty of color mixing. Silk-screen printing costs 0.1 yuan per color. Cylindrical bottles can be calculated as single-color, while irregular-shaped bottles are calculated as two-color or multi-color. Hot stamping with gold or silver costs 0.4 yuan per style.

6. If the glass bottles are made by hand molds, there may be some errors in capacity. When choosing, they should be inspected and the correct capacity should be marked. For example, those produced by automatic production lines are relatively uniform, but the shipment volume requirement is large, the cycle is relatively long, and the capacity is relatively stable.

7. Uneven thickness of glass bottles can easily lead to damage or they may be crushed by the contents in extremely cold conditions. During filling, the reasonable capacity should be checked. During transportation, paper wrapping should be used and each bottle should be separated individually. Color boxes should be provided on the products, and inner trays and middle boxes can better prevent vibration.

8. The commonly used bottle shapes of glass bottles are usually in stock, such as essential oil bottles, which are generally transparent or frosted. The manufacturing cycle of glass bottles is relatively long, with the shortest taking 20 days and some having a supply period of 45 days. Generally, the order quantity ranges from 5,000 to 10,000. The smaller the bottle type, the larger the quantity to be made. Both the cycle and the minimum order quantity are affected by peak and off-peak seasons.

9. Mold making costs: Manual molds are around 2,500 yuan, while automatic molds are generally around 4,000 yuan each. For 1 out of 4 or 1 out of 8, the cost is approximately 16,000 to 32,000 yuan, depending on the manufacturer's conditions.

10. The bottle cap process can feature electroplated aluminum engraving, gold-embossed edges, and etched lines. It comes in matte and glossy colors. It requires a gasket and an inner cap, and it is best to use it in conjunction with a pressure-sensitive sheet to enhance the sealing effect.

11. Essential oil bottles are usually tea-colored or colored with a matte finish, which can block light. The caps are equipped with safety rings and can be fitted with inner stoppers or droppers. Perfume bottles are generally equipped with delicate spray pump heads or plastic caps.

Iii. Hose

Hoses are classified into single-layer, double-layer and five-layer hoses, which differ in terms of pressure resistance, water resistance and hand feel. For instance, a five-layer hose consists of an outer layer, an inner layer, two adhesive layers and a barrier layer. Features: It has an excellent gas barrier function, effectively preventing the entry of oxygen and odorous gases, while also preventing the leakage of the fragrance and useful components of the contents.

2. Double-layer pipes are more commonly used. For medium and low-end ones, single-layer pipes can also be used. The hose diameters range from 13# to 60#. When choosing a hose of a certain diameter, different capacities are marked with different lengths. The capacity can be adjusted from 3ml to 360ml. For aesthetic harmony, for 60ml or less, diameters of 35# or less are commonly used. For 100ml and 150ml, 35# to 45# diameters are generally used. For capacities larger than 150ml, 45# or larger diameters are required.

3. In terms of process, they are classified into round tubes, oval tubes, flat tubes and ultra-flat tubes. Flat tubes and ultra-flat tubes have a more complicated manufacturing process compared to other types of tubes. They are also new types of tubes that have emerged in recent years, so their prices are correspondingly higher

4. Hose caps come in various shapes and are generally classified into flat caps, round caps, high caps, flip caps, ultra-flat caps, double-layer caps, spherical caps, lipstick caps, and plastic caps. They can also be processed in various ways, such as gold foil stamping, silver foil stamping, colored caps, transparent ones, oil spraying, electroplating, etc. Pointed caps and lipstick caps usually come with inner stoppers. The hose cap is an injection-molded product, and the hose is a drawn tube. Most hose manufacturers themselves do not produce hose caps. 5. Some products need to be sealed at the end after filling. Sealing at the end can be roughly divided into: straight line sealing at the end, diagonal sealing at the end, umbrella sealing at the end, star dot sealing at the end, and irregular sealing at the end. When sealing at the end, you can request to print the required date code at the sealing position.

6. Hoses can be made into colored tubes, transparent tubes, colored or transparent frosted tubes, pearlescent tubes, and are also available in matte and glossy finishes. Matte ones may seem elegant but are prone to dirt. The difference between colored tubes and those with large-area printing on the tube body can be identified from the cut at the tail. If the cut is white, it is a large-area printed tube, and the ink used has high requirements; otherwise, it is prone to falling off and cracking and showing white marks after being folded
