Market and Business Opportunity Analysis of Cosmetic Packaging

Cosmetic packaging has emerged as a rapidly growing niche segment in recent years. In an era defined by the "attention economy" and the "lipstick effect," cosmetic packaging is characterized by increasingly sophisticated printing, innovative structural designs, a focus on niche brands, and end-to-end service offerings. For companies struggling to gain a foothold in the fiercely competitive packaging industry, now is the time to carefully examine the business opportunities brought about by the evolving trends in the cosmetics sector. Below, we share some concise insights into the cosmetics industry—feel free to bookmark this article if you're interested. 01. Industry Size and Growth China is the world’s second-largest consumer of cosmetics after the United States, accounting for 12.7% of the global cosmetics market. As the second-largest cosmetics consumer, China’s beauty and personal care market reached 477.7 billion yuan in 2019, representing a year-on-year growth of 13.8%. Compared with other consumer sectors, according to data from the National Bureau of Statistics, retail sales of cosmetic products in China grew by 12% in 2019, ranking second only to daily necessities, which saw a growth rate of 13%. 02. Leading Brands and Their Parent Companies In the Chinese cosmetics market, domestic brands hold a slightly larger market share than international brands. By 2018, the market share of domestic cosmetic brands had risen to 56%. The high-end market remains dominated by international brands, while most domestic brands target the mass market. Domestic brands have deepened their distribution channels and enjoy a clear advantage in lower-tier, third- and fourth-tier markets. Online, the most notable shift in 2019 was the rise of Douyin E-commerce and Taobao Live, which further shortened the distance between consumers’ initial interest (“planting grass”) and actual purchase. Thanks to advantages such as broad distribution channels, cost-effectiveness, and rapid supply-chain responsiveness, domestic cosmetic brands have steadily increased their market share. The main publicly listed Chinese cosmetic brands include Proya, Marubi, Shanghai Jahwa, Yujiahui, HuaXi Bio, and Betaine.

What is a wide-mouth bottle?

What is a wide-mouth bottle?

A wide-mouth bottle is a commonly used container with a broad opening and a relatively short neck. Its key feature is its large opening size, which makes it easy to add or remove solid materials and facilitates convenient handling operations. Key Features: The diameter of the bottle mouth typically ranges from 2 to 10 centimeters. The opening is wide and often features a frosted finish, paired with either a glass stopper or a rubber stopper to ensure an airtight seal. The materials are primarily glass and plastic. Glass bottles offer high transparency and excellent chemical stability, while plastic bottles are lightweight, shatter-resistant, and less prone to breakage. The design is simple and straightforward; most bottles have a cylindrical shape. They come in a variety of capacities, ranging from tens of milliliters to several liters, making them suitable for different application scenarios. Main Uses: In laboratory settings, these bottles are mainly used for storing solid reagents, powdered or granular chemicals, allowing for easy pouring or retrieval using tools. In daily life and industrial applications, they can hold pharmaceuticals, food ingredients, cosmetic raw materials, and even serve as simple reaction vessels, facilitating the addition of materials and mixing processes. Some wide-mouth bottles equipped with sealed lids can also be used for sample preservation and specimen storage, thanks to their excellent sealing performance, which helps prevent moisture absorption or contamination of the contents. Usage Precautions: Glass bottles should be protected from strong impacts to avoid breakage; plastic bottles are not recommended for containing highly corrosive substances. When storing chemical reagents, select a stopper that is appropriate for the nature of the reagent to prevent unwanted reactions that could compromise the seal or affect the reagent's stability.

The three most common types of cosmetic packaging materials

The three most common types of cosmetic packaging materials

I. Glass Bottles Glass bottles are primarily used as packaging materials for skincare products (creams, moisturizing lotions), eau de toilette, single-ingredient essential oils, and nail polishes—products with relatively small volumes. Skincare products exceeding 200 ml in volume are less commonly packaged in glass bottles. The main printing methods employed are silk-screening ink and hot stamping, with each method typically applied no more than twice. Overprinting too many layers can lead to a higher rate of defective products and increased costs. Glass bottles come in two main types: wide-mouth bottles and narrow-mouth bottles. Solid-form creams generally use wide-mouth bottles, fitted with aluminum or plastic caps; the bottle stoppers can be designed with features such as color pumps. Emulsion-based creams or liquid formulations usually come in narrow-mouth bottles, ideally suited for pump-action mechanisms. If equipped with an outer cap, they should also include an inner seal; liquid formulations require small circular holes paired with inner seals, while thicker moisturizing lotions should use perforated inner seals. II. Plastic Bottles Plastic bottles are typically made from materials such as PP, PE, K-material, AS, ABS, acrylic, and PET. Products like thick-walled cream jars, stoppers, caps, gaskets, pump mechanisms, and dust covers for skincare items are usually manufactured using injection molding. PET blow-molded bottles are produced in a two-step process: the preform is injection-molded, and then the finished product is blow-molded. Other products, such as thinner-walled moisturizing lotion bottles and cleansing bottles, are typically blow-molded. PET material is a new environmentally friendly material characterized by high barrier properties, lightweight construction, shatter resistance, solvent resistance, and exceptional light transmission. It can be produced in matte, colored, frosted white, or fully transparent finishes and is widely used for packaging gel-like products. Acrylic material is suitable for injection-molded bottles but has weaker acid resistance; it generally cannot directly hold creams without an internal liner. When filling such bottles, avoid overfilling to prevent cream from seeping between the inner liner and the acrylic bottle, which could cause cracking. AS and ABS: AS offers good clarity, while ABS provides excellent flexibility. III. Plastic Tubes Plastic tubes are categorized into single-layer, double-layer, and five-layer tubes, each offering different advantages in terms of pressure resistance, leak-proof performance, and tactile feel. For example, a five-layer tube consists of an outer layer, an inner layer, two adhesive layers, and an additional barrier layer. This structure provides excellent gas-barrier properties, effectively preventing the penetration of oxygen and odorous gases while also keeping the contents' fragrance and active ingredients from leaking out. Double-layer tubes are the most commonly used type. Plastic tubes can be produced in colored, transparent, frosted-colored, or frosted-transparent finishes, and they come in both matte and glossy varieties. Matte tubes have an elegant appearance but tend to show dirt more easily. The above is a general classification of packaging materials commonly used by cosmetic OEM manufacturers. Of course, each category encompasses a wide variety of specific packaging options. We hope you can find the right packaging materials that perfectly suit your cosmetic products, helping your brand reach a higher level.

How do you inspect cosmetic packaging materials to ensure they meet quality standards?

How do you inspect cosmetic packaging materials to ensure they meet quality standards?

The key indicators include tactile feel, requirements for filling machines, transportation vibration standards, air-tightness performance, material compatibility requirements, dimensional compatibility issues, tolerances and color variations in aluminum-plastic composites, as well as production capacity and filling volume that must meet the product’s declared specifications. Cosmetic injection-molded bottles represent both an industry and a cultural phenomenon. In today’s financial environment, cosmetics remain a sunrise industry with an unshakable market position. However, the quality of cosmetic bottle custom manufacturers varies widely. Therefore, upon receiving the goods, it’s essential not only to verify that the quantity is complete but also to inspect the quality. So, how do we check whether the quality of cosmetic injection-molded bottles meets the required standards? What are the relevant criteria? 1. Appearance: Primarily conducted by visual inspection under sufficient lighting conditions, using normal vision at a distance of 20–30 cm directly in front of the eyes. Check whether the surface has defects such as blemishes, foreign particles, or scratches. 2. Dimensions: Use a ruler or a vernier caliper with an accuracy of 0.02 mm to measure and record the dimensions of the sample, verifying whether they conform to the specified standards. 3. Weight: Use a balance with a resolution of 0.1 g to weigh the sample and record the value, ensuring it matches the agreed-upon dimensional standards. 4. Capacity: Place the sample on a balance with a resolution of 0.1 g, subtract the tare weight of the bottle, fill the sample bottle completely with tap water, and record the value (if necessary, directly inject the paste or convert the density of water to that of the paste). 5. Adhesion of Printing and Durability of Hot Stamping (Gold/Silver): ① Cover the printed and hot-stamped (gold/silver) areas with 3M810 test tape, smooth it out to eliminate air bubbles, then quickly peel it off. Repeat this process three times for the printed area and twice for the hot-stamped (gold/silver) area. ② Wipe the printed area back and forth twice using gauze soaked in disinfectant alcohol. 6. Flip-Top Performance: At room temperature, manually flip the flip-top lid open and closed 200 times without any breakage. The tightness and sealing should remain consistent with the condition before testing. 7. Cap Compatibility Test: The cap should fit smoothly without slipping. Bottle-to-cap connections can be either threaded or snap-fit. For snap-fit bottles, the gap between the bottle and cap should be ≤0.4 mm; for threaded bottles, the gap should be between 0.1 mm and 0.6 mm. 8. Leak-Proof Testing: ① Fill the bottle with water weighing or measuring the same amount as the net content of the product, place it in a vacuum chamber, and evacuate the air down to -0.05 MPa, maintaining this pressure for 5 minutes. There should be no leakage. ② If the above vacuum test fails, fill the bottle with water weighing or measuring the same amount as the net content, leave it standing for 24 hours, and there should still be no leakage. (This method applies only to wide-mouth bottles.) 9. Drop Test: Fill the bottle with water weighing or measuring the same amount as the net content of the product, close the lid, and drop it from a specified height three times each: first, with the lid facing downward at a 45-degree angle; second, flat and free-falling with the bottom vertically facing down onto a cement floor. There should be no cracks, leaks, or separation of components. For products labeled with a net content > 200 ml/g, the drop height is 1.2 m; for those labeled with a net content ≤ 200 ml/g, the drop height is 1.5 m. 10. Heat and Cold Resistance Tests: ① Heat Resistance Test: Fill the sample bottle with water weighing or measuring the same amount as the net content, place it horizontally in a constant-temperature oven (48 ± 1℃) for 24 hours. There should be no cracks, deformation, discoloration, or leakage. ② Cold Resistance Test: Fill the sample bottle with water weighing or measuring the same amount as the net content, place it horizontally in a refrigerator (between -10℃ and -15℃) for 24 hours. There should be no cracks, deformation, discoloration, or leakage. 11. Barcode Readability: The barcode should be readable clearly and accurately in one go using a barcode scanner. 5.4 Batch-by-Batch Inspection Judgment for Pass or Fail: For appearance inspection items and functional inspection items, based on the results of the sample inspection, if the number of defective items found in the sample is less than or equal to the acceptance criterion, the batch is considered pass; if the number of defective items found exceeds or equals the rejection criterion, the batch is considered fail.

It’s suitable for containing conventional products such as shampoo, body wash, and conditioner. It offers excellent cost-performance and is recyclable, aligning with current environmental trends. HDPE Material: Made from high-density polyethylene, this material is milky-white and opaque. It features good toughness, impact resistance, and excellent moisture-proof properties. It’s ideal for holding body lotions and hand sanitizers. Some hotels even use it for press-type bottles, which are durable and resistant to breakage. PP Material: Polypropylene material has good heat resistance and can withstand hot water rinsing at certain temperatures without deforming easily. It’s often used for toiletry bottles equipped with pump heads or single-use, small-capacity dispensers—safe and odor-free. Less Common Materials: Glass (accounting for less than 10%) Glass is used sparingly by high-end hotels and boutique guesthouses, primarily to enhance the texture and premium feel of the product. Its main advantages are its high-quality texture and reusability, which align well with brands’ “eco-friendly and sustainable” philosophies. It’s particularly suited for custom-made toiletry products. However, its limitations include being heavy, fragile, and costly to transport and handle. Thus, it’s best suited for high-end settings with a limited number of rooms and a focus on personalized, high-quality service. Special Scenario Additions: Disposable Toiletry Sets: These often use thin LDPE (low-density polyethylene) material, which is lightweight and inexpensive. They’re ideal for budget hotels and economy-class accommodations, meeting the demand for single-use items. Leak-Proof Requirements: Some hotels opt for plastic bottles equipped with sealed inner caps, paired with pump heads or screw-top closures, to prevent leakage during transportation and storage.
