Using PET preforms allows for reducing costs in the production, storage, and logistics of plastic containers. They vary in size, color, and neck format. The 21.8 g preform is designed for producing a bottle with a 0.5-liter capacity. The weight of the product is 21.8 grams. The finished container is obtained by blowing the heated form. The technology allows for changing the configuration of the finished bottle, branding the flask or lid.
For bottles with a 0.5-liter volume, you can order preforms ranging from 14.2 to 21.8 grams. What's the difference? The difference lies in the thickness of the plastic. The first option is acceptable for points of sale for bottled beverages. If containers are needed for transporting and storing liquids in warehouses or retail shelves, the 21.8/28 preform for bottles is recommended. These are denser flasks with a 28 mm neck. The standard presentation is in a red shade. Custom colors can be produced by adding a different pigment to the polymer. It is also possible to manufacture the preform without pigment.
The neck standard for red-colored preforms is PCO 1881. This is a low-neck format. It has a classic thread for screwing. When selecting compatible lids, pay attention to the "neck standard" parameter. It should also be PCO 1881. Red 21.8 preforms can be combined with 2.05 g and 2.10 g lids with a 28 mm diameter.
