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...

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....

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...

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...
