PET preforms are small, test-tube shaped plastic pieces that undergo heating and blowing in a mold to form the final bottle shape. The “3025” designation refers to specific dimensions and weight characteristics of the preform: typically, it is 30 mm in neck diameter with a length of about 25 grams in weight.

This size is commonly used for bottles with capacities ranging from 500 ml to 1 liter, making it a versatile choice for various packaging needs.

One of the primary advantages of the 3025 PET preform is its lightweight construction. Compared to heavier preforms, the 3025 strikes an excellent balance between material use and structural integrity. Using less plastic reduces raw material costs, lowering production expenses without compromising bottle strength.

The lightweight nature of bottles made from 3025 preforms also reduces transportation costs due to lower overall package weight. This efficiency benefits manufacturers and distributors by minimizing fuel consumption and shipping expenses, contributing to more sustainable logistics.

Despite being lightweight, the 3025 PET preform produces bottles that are strong and durable. The intrinsic properties of PET combined with optimized preform design ensure bottles can withstand handling stresses during filling, packaging, and transportation.

Bottles formed from 3025 preforms exhibit excellent impact resistance and good barrier properties against moisture and gases. This durability protects the contents, preserving freshness and extending shelf life, which is especially important for beverages such as water, juices, and soft drinks.
