High Quality 1810 and 1881 PET Preforms Custom OEM Company

In the packaging industry, PET (polyethylene terephthalate) preforms are critical components used in the creation of bottles and containers. These preforms, which are essentially molded pieces of plastic, are transformed into final products through a blow-molding process. Among the various preform sizes available, the 1810 and 1881 PET preforms are two popular options. Each has distinct features and applications that make them suitable for different uses.

PET preforms are intermediate products used in the manufacture of PET bottles and containers. They are designed to be heated and then blown into their final shape, which can include bottles for beverages, personal care products, and various other containers. The numbers in PET preform designations, such as 1810 and 1881, refer to specific dimensions and neck sizes, which influence the preform’s suitability for various applications.

1810 PET Preforms: Characteristics and Uses

The 1810 PET preform is characterized by a neck size with a diameter of approximately 18mm and a height of around 10mm. This size is relatively small and is often used for applications where a smaller container is preferred. Here are some common applications and advantages of the 1810 PET preform:

Cosmetics and Personal Care Products: The 1810 PET preform is frequently used for packaging personal care products such as lotions, shampoos, and creams. The small neck size is ideal for products that are dispensed in small quantities and require precise control during use.

Pharmaceuticals: Smaller PET preforms are also suitable for pharmaceutical packaging. The 1810 size is often used for packaging supplements, vitamins, and other health-related products that come in small doses.

Small Beverage Bottles: Although less common, the 1810 preform can be used for small beverage bottles, such as those for flavored water or single-serving juices. The compact size makes it suitable for products aimed at convenience and portability.

The primary advantage of the 1810 PET preform is its compatibility with smaller filling and capping equipment. This size allows for efficient production and handling, which is beneficial for applications requiring smaller quantities or specialized containers.

1881 PET Preforms: Characteristics and Uses

The 1881 PET preform, on the other hand, features a neck size with a diameter of approximately 18mm and a height of about 81mm. This preform size is larger in height compared to the 1810, which impacts its use and application. Here are some typical uses and advantages of the 1881 PET preform:

Beverages and Drinks: The 1881 PET preform is commonly used for larger beverage bottles, such as those for soft drinks, juices, and sports drinks. The increased height allows for a greater volume capacity, making it suitable for products that are consumed in larger quantities.

Household Products: In addition to beverages, the 1881 preform is used for household products like cleaning solutions and detergents. The larger neck size accommodates the filling of thicker liquids and enables easy dispensing.

Food Packaging: The 1881 PET preform is also utilized in the food industry for packaging products such as sauces, oils, and dressings. The larger neck size allows for a more convenient pour and better access to the product.

One of the main advantages of the 1881 PET preform is its ability to handle larger volumes. The design supports higher-capacity containers and can withstand the pressures associated with carbonated beverages and other filled liquids.
