The Structure of Shaped Bottle Embryo and The Classification of Shaped Bottle Embryo
May 22,2023
The structure of a shaped bottle embryo refers to the physical form and components of the preform or embryo used in the manufacturing process of shaped bottles. Here is a general overview of the structure of a shaped bottle embryo:
Material: Shaped bottle embryos are typically made of a thermoplastic polymer, commonly polyethylene terephthalate (PET). PET is widely used in the production of bottles due to its transparency, strength, lightweight nature, and excellent barrier properties.
Neck and Thread: The shaped bottle embryo has a neck portion at the top, which is designed to accommodate the bottle cap or closure. The neck may include threading or other specific features to ensure a secure attachment of the cap.
Body: The body of the shaped bottle embryo is the main section that forms the body of the bottle. It is usually cylindrical in shape but can have various contours and design features depending on the desired shape of the final bottle. The body may have decorative elements, embossed logos, or other unique design characteristics.
Bottom: The bottom of the shaped bottle embryo is the base that provides stability to the bottle. It is typically flat or slightly concave to allow the bottle to stand upright.
Wall Thickness: The wall thickness of the shaped bottle embryo may vary depending on the specific requirements of the bottle. The wall thickness is carefully designed to provide the necessary strength and rigidity while optimizing material usage.
Injection Point: Shaped bottle embryos are produced through injection molding. They have an injection point or gate, which is the location where the molten plastic material is injected into the mold cavity during the manufacturing process. The injection point is typically located at the bottom or side of the embryo and is later removed or trimmed.
It's important to note that the exact structure of a shaped bottle embryo can vary depending on the specific design, size, and intended use of the bottle. Manufacturers may incorporate additional features or modifications to suit their specific bottle designs and production processes.Besides,Shaped bottle embryos, also known as preforms, can be classified based on various factors, including their size, shape, and intended application. Here are some common classifications of shaped bottle embryos:
Size:
Small Preforms: These preforms are typically used for producing small-sized bottles, such as single-serve beverage bottles, travel-sized containers, or sample-sized packaging.
Medium Preforms: Medium-sized preforms are commonly used for producing bottles with a moderate capacity, such as personal care products, household cleaners, and condiments.
Large Preforms: Large preforms are used for producing bottles with a higher capacity, such as large beverage containers, industrial chemicals, or bulk packaging.
Shape:
Cylindrical Preforms: Cylindrical-shaped preforms are used to produce bottles with a cylindrical body shape, which is common for many beverage bottles and general-purpose containers.
Non-Cylindrical Preforms: Non-cylindrical preforms are used to produce bottles with unique or customized shapes, such as square, oval, rectangular, or other geometric forms. These shapes are often chosen for aesthetic purposes or to enhance product differentiation.
Application:
Beverage Preforms: These preforms are specifically designed for producing bottles used in the beverage industry, such as water bottles, carbonated drink bottles, juice containers, and sports drink bottles.
Personal Care Preforms: Personal care preforms are used for producing bottles used in the personal care and cosmetics industry, such as shampoo bottles, lotion containers, and liquid soap dispensers.
Food and Household Preforms: These preforms are used for producing bottles used in the food industry, as well as for household products like cooking oils, sauces, detergents, and cleaning agents.
Material:
PET Preforms: PET (polyethylene terephthalate) is the most commonly used material for preforms due to its transparency, lightweight nature, durability, and excellent barrier properties.
Other Material Preforms: In some cases, preforms may be made from alternative materials such as polypropylene (PP) or high-density polyethylene (HDPE) to meet specific requirements for certain applications or products.
It's important to note that the classification of shaped bottle embryos may vary among manufacturers, and there may be additional subcategories based on specific features, design variations, or industry-specific requirements. When selecting shaped bottle embryos, it's crucial to consider the specific needs of the bottle design, intended application, and production processes.
