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 daily cleaning products such as shampoo, shower gel and conditioner, PET (polyethylene terephthalate) bottles stand out from many plastic products and become the main choice in the market due to their excellent transparency, outstanding physical properties, mature recycling system and flexible processing technology. This time we will introduce PET bottles as a plastic container from three aspects: functional advantages, processing technology and structural design innovation.   1. Functional advantages of PET bottles PET bottles have several key advantages in the packaging of cleaning products: Lightweight and shatterproof: PET is durable and not easy to break even if it falls in a humid environment such as the bathroom, ensuring safe use. Compared with glass bottles, it greatly reduces transportation costs and carbon dioxide emissions. It can effectively resist impact during transportation, storage and use, and reduce the risk of breakage and leakage. High transparency: P...

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...

Contents change color or evaporate? Is the barrier property of the glass bottle not good enough? Many customers have reported problems such as discoloration, abnormal odor, and decreased concentration of skin care products during product sales or use. This is especially true for skin care formulas containing essential oils, active ingredients, or natural plant extracts. In other words, during product sales or daily use, consumers often report that skin care products have changed color; some products emit abnormal odors, which not only affects the user experience, but may also have an adverse effect on skin health; and some customers have found that the concentration has decreased after use, which undoubtedly reduces the effectiveness of the product.   Cause analysis These problems are often closely related to the poor light-blocking ability and airtightness of glass bottles. Although transparent glass has a good visual effect, it is easy for external factors such as ultraviolet ra...
