Product Introduction
PET mineral water bottle preforms are injection molded from bottle-grade virgin PET resin. Downstream factories heat, stretch, and blow mold them. Then 200ml to 2L mineral water, purified water, plus other beverage bottles get produced. As a direct factory, we make these high-quality PET mineral water bottle preforms, adopting a 29/25 water bottle standard system with a three-start thread design. The outer diameter is precisely controlled to ensure compatibility with caps and high-speed filling lines.

Key Advantages of the High-Quality PET Mineral Water Bottle Preforms
Stable Material for Drinking Water Filling
PET has good transparency and high gloss. Its barrier performance is strong, plus water absorption is low. It is light weight and has good toughness. So, it is one of the main materials for beverage bottle packaging. This product is made from food-contact grade virgin PET resin. The acetaldehyde content is low. So the taste or smell of drinking water is not affected. It is suitable for premium mineral water. Also, it fits odor-sensitive drinking water filling.
29/25 standard structure with Strong Compatibility
The neck specification follows a standard water bottle neck finish system with a three-start thread design, featuring a 29mm neck finish and 25mm flow opening for full compatibility with caps and filling lines. Fits most mineral water caps and filling-line equipment on the market. Capper replacement is usually unnecessary. Conveyor equipment needs no major changes either. So, just run the preforms directly on existing production lines.
Wide Weight Range for Flexible Selection
Weight 12g to 43g, 15 standard specs available. Fits 200ml small bottles, 500ml standard sizes, or 1L, 1.5L and 2L large bottles. Pick the right weight based on bottle shape, transport needs and budget. No need for different suppliers for different capacities.
Consistent Dimensions to Reduce Reject Rate
Stable bottle blowing depends on weight tolerance, wall thickness, and neck precision. Weight, thread accuracy, support ring dimensions, and wall thickness distribution are strictly checked in production. Consistent preform dimensions help reduce the reject rate and improve production efficiency.
Customization Options
As a manufacturer, several customization options are available to match different production needs:
Custom Weight: Standard preform weights range from 12g to 43g. If different weights are required, development can be arranged based on bottle drawings and project specifications.
Custom Color: Transparent is the standard option. Light blue, green, amber, and white are commonly requested too. Other color requirements can also be discussed.
Logo: Customer logos or specific text can be molded directly onto the preform during production.
Packaging: Standard packaging is available, while custom packing methods can be arranged according to shipping or storage requirements.
Other Specifications: Different outer diameters, thread standards, and special technical requirements can be confirmed with the engineering team before production starts.
FAQ
Q1: Are samples available?
A: Yes. Can provide samples before a formal order to confirm size, weight, and appearance.
Q2: Is the product suitable for high-speed blow molding lines?
A: Yes. Neck finish tolerance, support ring dimensions, and weight consistency are strictly controlled to ensure compatibility with high-speed automatic blow molding lines.
