45, 46, and 48mm PET preforms have their own characteristics and advantages, mainly reflected in the following aspects
Wide applicability: PET preforms of different diameters can meet various packaging needs. 45mm threaded PET preforms are available in various weights ranging from 100g to 180g, and can be used in industries such as food and beverage, pharmaceuticals, and personal care. The 48mm PET preform is suitable for producing durable and lightweight bottles, which can be used to package products such as water with a capacity of up to 10 liters.
Good sealing: The thread design of these bottle preforms is precise, which can achieve safe closure, ensure the integrity of the packaging contents, and effectively prevent leakage. It is of great significance for products that require sealed storage, such as liquids, sauces, drugs, etc.
Superior mechanical properties: PET preforms have good mechanical properties, with an impact strength 3-5 times that of other films, good folding resistance, and the ability to withstand certain external forces during transportation and storage. They are not easily broken, ensuring the safety of the product.
Excellent barrier performance: PET material has low gas and water vapor permeability, excellent gas, water, oil, and odor resistance, which can effectively maintain the quality and flavor of packaging contents and extend the shelf life of products.
Hygiene, safety and reliability: PET bottle preforms are non-toxic, odorless, with low heavy metal content and acetaldehyde content, meeting international food safety standards. They can be directly used for food packaging without causing pollution to the packaging contents, ensuring the health of consumers.
High production efficiency: PET preforms are produced using injection molding technology, which is highly automated with low processing temperatures, wide processing range, high product transparency, and high yield. This can effectively reduce production costs and improve production efficiency.
Environmentally friendly and recyclable: PET is a thermoplastic that can be melted and reshaped multiple times without losing its performance. It has the characteristic of 100% recyclability and has minimal impact on the environment throughout the entire lifecycle from production, use to recycling, meeting the requirements of sustainable development.
