Production Process: PET preforms are typically manufactured through a process called injection molding. The PET resin is melted and injected into a mold cavity, where it takes the shape of the preform. The threaded neck is also formed during the molding process.
Neck Finish: PET preforms have threaded necks that allow for easy and secure attachment of closures, such as caps or lids. The specific design and size of the neck finish may vary depending on the intended application and industry standards.
Oxygen and Moisture Barrier: In addition to their good barrier properties, PET preforms offer excellent oxygen and moisture barrier characteristics. This helps to prevent oxidation and moisture ingress, thereby preserving the freshness and quality of the packaged products for an extended shelf life.
Hot-fill Capability: PET preforms have the ability to withstand hot-filling processes, where hot liquids or products are filled into the containers. This is particularly advantageous for products that need to be filled at elevated temperatures, such as hot beverages, sauces, or soups.
Tamper-evident Features: PET preforms can be designed with tamper-evident features, such as tamper bands or induction seals, to provide additional security and assurance to consumers. These features help to indicate if the product has been tampered with before purchase.
Customization Options: PET preforms can be customized with various colors, finishes, and labeling options to meet specific branding and marketing requirements. This allows manufacturers to create unique and visually appealing packaging solutions.
Compatibility with Recycling Infrastructure: PET preforms are widely accepted in recycling facilities and can be easily recycled into new PET products. This contributes to the circular economy and reduces the environmental impact of plastic waste.
