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...

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...

I.Color: Slight color deviation from the Pantone color chart will be determined based on the Pantone color chart. II.Finished Product Defects：Mold line misalignment is noticeable and can cause hand injuries. III. Common Appearance Defects: Cracks, chips, chipped corners, deformation, glass ripping, internal wall sticking, and sharp punctures that may affect the seal and pose a risk of injury. Cold marks, pitting, brush marks, wrinkles, stubble marks, scissor marks, base thickness variations, and minor scratches may also be present on the bottle. Discoloration, black spots, bubbles, and pinholes may be present elsewhere. IV.Foreign Objects: Broken glass, insects, metal, blood, and other issues. Check the bottle's interior and exterior for visible foreign objects such as oil, water, paper scraps, and small impurities. V. Process Spraying The sprayed surface is not smooth or flat; it may exhibit streaks, wrinkles, frosting, orange peel, or other defects. On the main viewing surface: Two p...

Test focus: Chemical Resistance: Products containing strong acids or bases, particularly those containing strong acids or bases, may corrode the glass surface. This corrosion may cause glass flakes to break off, form visible particles, or imperceptibly damage the integrity of the glass. Furthermore, these substances can dissolve alkali metal ions. If these ions accumulate on or within the glass, they can cause a dramatic shift in the glass's pH, altering its chemical properties and ultimately affecting its performance and lifespan. Inner layer surface treatment: whether the release agent, siliconizing agent or other inner coating is compatible with the contents, whether it migrates or affects the stability of the contents. Metal Cap/Pump Head Compatibility: While glass itself is inert, the accompanying metal cap (available in tinplate or aluminum) and pump head (made from various types of plastic and metal springs) must be compatible with the contents. This is because corrosion and rus...
