I. Prolonged exposure to sunlight One of the main reasons colored bottles fade is prolonged exposure to sunlight. UV rays break down the color pigments or coatings used on the surface of the bottle, causing them to dull or discolor. This is especially true for spray-painted or frosted bottles with lighter shades.Colored bottles stored in high heat or direct light are more likely to experience color changes. Stacking or rubbing during shipping can also cause scratches and color loss. II. Use of poor-quality paints by suppliers Many manufacturers use low-grade coatings or processes to reduce production costs, but this method will cause the products to fade. Poor-quality materials cannot withstand high temperatures, humidity or friction during transportation. III. Deficiencies in materials and processes 1.Uneven pigment dispersion: Insufficient mixing of the masterbatch leads to color differences.When the melting point difference between the masterbatch and the su...

In the $180B global cosmetics market, customizable tubes dominate 67% of skincare packaging.Cosmetic tubes are widely used in cleansers, eye creams, primers, sunscreens and other products due to their lightness, good sealing and portability. This article will give you a comprehensive understanding of tube packaging from three aspects: the manufacturing process of tubes, surface treatment technology and common types of matching caps. Manufacturing Process of Skin Care Tubes Skin care tubes are usually made of PE (polyethylene) plastic, aluminum foil, plastic film and other materials.They are made into sheets by co-extrusion and compounding, and then pressed into tubular containers by a special tube making machine. The production process of tubes mainly includes: extrusion molding → cutting → printing → sealing → capping. Each step needs to be precisely controlled to ensure aesthetics and sealing. According to product type and usage requirements, they can be divided i...

In the beauty and personal care industry, aluminum hoses have gradually become a friendly choice for many brands due to their excellent functionality, environmental friendliness and high-quality texture. Here we will help brands and buyers understand the cost-effective packaging solutions of aluminum tubes from three aspects: functional advantages, manufacturing processes and product structure design. 1. The main functions and advantages of aluminum tubes Strong barrier properties：Aluminum naturally has good light-blocking and oxygen-blocking properties. The molecular structure of aluminum can block 99% of ultraviolet rays, oxygen and water vapor, effectively protecting active ingredients (such as VC, retinol) from oxidation and deterioration, extending the shelf life. It is particularly suitable for creams, gels, essences and other products that are easily affected by air. Good extrudability：The hose has excellent elasticity and controllable resilience, which can accurately control th...

In the cosmetics and skincare industry, the choice of packaging containers directly affects the product's cost, market positioning, brand image, user experience and even environmental image. Especially when launching new product packaging materials, "glass containers or plastic containers?" often becomes the core issue of concern to brands and packaging suppliers. This article will compare the advantages and disadvantages of glass containers and plastic containers in depth from the dimensions of functionality, appearance texture, environmental protection, cost control, and transportation safety, which will help you make a more suitable choice.   1.Advantages and disadvantages of glass containers advantage: High-end texture: The glass bottle has a transparent appearance and high-end texture, suitable for positioning high-end skin care brands. It has a strong sense of classic luxury, conveying a pure, natural, professional and trustworthy image. It has high transparency and is stabl...

In the skin care industry, glass bottle packaging is widely used in high-value-added products such as essences, creams, lotions, and facial oils due to its high-end texture, excellent chemical stability (strong barrier properties and good sealing properties) and environmentally friendly properties. These characteristics make it an ideal choice for enhancing product image and ensuring quality. However, brands or buyers often face a series of specific problems in the process of transporting glass packaging materials, which may affect the final product experience and brand image. Problem manifestations: 1. During the process of receiving, transporting (especially international transport) or filling, the bottle body is broken, shattered, cracked, corners are broken, and the edge of the bottle mouth is broken. 2. It leads to high loss rate, affecting cost and product availability. Main reasons: 1. Insufficient bottle material and strength: The glass is too brittle, and high borosilicate gla...

1.Thickness measurement The precise thickness of each layer of a tube is fundamental to its performance. This test uses a micrometer or specialized thickness gauge to measure the actual thickness of each layer (from the inner barrier film to the outer printed layer), typically at five to ten points throughout the tube. The goal is to ensure compliance with design specifications. 2.Sealing performance test Heat Seal Strength (Tube End): Cosmetic Plastic Cream Tube ends are sealed using heat during the manufacturing process. This test measures the force required to tear the seal. It ensures that the seal will not crack during extrusion, transportation, and storage. Standards generally require a minimum strength to ensure reliability. Torque Test (Tube End to Cap): This test evaluates the tightness of the connection between the tube end and the cap. A torque meter measures the force required to unscrew or tighten the cap, ensuring it is neither too loose nor too tight....

 Jars： Glass Jar (Heavy, Luxury, and Temperature-Resistant) Glass Jar come in a variety of formats, including jars, bottles, and vials, making them ideal for products requiring the utmost purity. Amber or frosted glass variants offer UV protection, protecting light-sensitive ingredients like retinol or vitamin C from degradation. Plastics Jar (such as PETG, ABS, and PP, which are lightweight and easy to process) are widely valued for their durability and cost-effectiveness. High-density polyethylene (HDPE) and polypropylene (PP) are common choices, offering chemical resistance and lightweight advantages. Plastic jars with screw-top lids are suitable for body butters and thicker lotions. Features: Classic and traditional, easy to use, and easy to show the paste texture and color. However, the contents are frequently in contact with air and fingers, which requires a high level of antiseptic system. Applicable to: Luxurious nourishing facial creams, sleeping masks, massage creams, ne...

For skincare brands, the texture and quality of glass bottles directly impact product premiums, and the manufacturing process is crucial to determining quality. Currently, mainstream glass bottle manufacturing processes primarily focus on blowing, tubing, and drawing. Different processes correspond to different product characteristics, necessitating distinct considerations when selecting suppliers. 1.The blowing process is an excellent representative of high-end skin care glass bottles. The blowing process is mainly used to manufacture bottles with complex shapes, thick walls, and high-end appearance. It is especially suitable for customized bottles, such as irregular essential oil bottles and retro cream jars. When selecting a blow-molded bottle supplier, focus on three key aspects: Mold development capabilities. A good supplier should possess independent mold design and processing capabilities, accurately reproducing details such as bottle body texture and bottle neck curvature based...
