Screw Neck PET Preform For Food Grade

We are a China-based manufacturer producing Screw Neck PET Preform For Food Grade, designed for bottled water, carbonated drinks, edible oil, and liquid pharmaceutical packaging. Every preform is molded from 100% virgin PET-odor-free, contaminant-free, and crystal clear. The neck threads are precision-cut for a tight, leak-proof seal that holds through filling, stacking, and shipping. With large-volume wholesale supply capabilities, we support high-capacity bottling operations and keep production lines running without interruption.

Precise Thread Design, Zero Leakage Protection

Screw Neck PET Preform For Food Grade is made with precise injection molded threads. It matches all standard bottle caps perfectly. We make long threads, short threads and thin threads for different caps. The tight thread structure stays locked well during filling, pasteurization, stacking and delivery. It stops liquid leak and loose caps even when pressure or temperature changes.

Safe for Food Contact with Official Certificates

All preforms use new food-grade PET material only. They meet FDA 21 CFR and EU 10/2011 rules. We never use recycled plastic. No heavy metal inside. The acetaldehyde level is safe. You can use them for all food and drink products safely.

Even Wall Thickness Cuts Your Production Waste

Each preform's weight error is within ±0.3g. It makes bottle blowing easy and steady. Fixed preform weight lets you calculate material cost clearly. No unexpected extra cost.

High Clear Look, Better Sales on Store Shelves

PET material is very clear. Bottles blown from these preforms have bright, shiny surfaces. They work great for soda, fruit juice, cooking oil and other goods where clear looks help sell more.

Full Neck Sizes Fit Most Common Caps

We offer 28mm, 30mm, 38mm neck sizes. They fit screw caps, anti-theft caps, sport caps and pump caps. All sizes follow CT and SP industry rules. Your cap tightening machines work directly without changes. No stuck or tilted caps.

Optional Support Ring for Large 3L–5L Bottles

For 3L to 5L big bottles, 38mm necks can add one-piece support rings. The ring holds preforms straight in ovens and blowing machines. It stops uneven wall thickness. After blowing, the ring strengthens bottle necks. Bottles stay straight and tight-sealed full of liquid.

One Preform Line for Many Products

The same preform style fits bottled water, soda, cooking oil, liquid medicine, shampoo and hair conditioner. Just pick the right weight and neck size. One mold can make preforms for many different goods.

Easy Custom Service

Do you need preforms in special colors, weights or with your logo? We can make them for you. We adjust every detail to match your bottle plan simply and flexibly.

Bottled Water Packaging

This Screw Neck PET Preform For Food Grade​ works for water bottles from 500ml to 5L. Consistent thread accuracy ensures smooth capping with no jamming or misalignment, keeping high-speed lines running steadily. Leakage and rejection rates drop together-delivering measurable cost advantages at scale.

Carbonated Beverage Packaging

Suitable for soda, sparkling water, and other fizzy drinks. The fine-pitch thread design increases the contact area between cap and neck for a tighter seal, preventing CO₂ loss and keeping flavor stable throughout the shelf life.

Edible Oil Bottles

Works for all edible oil bottle formats. The screw neck maintains a secure closure across temperature variations, preventing leaks and oxidation during transport. Preform weight can be matched to each bottle size-balancing strength with material efficiency.

Dairy Product Packaging

Designed for milk drinks and other liquid dairy products. The blown bottle stays clear and clean-looking with no hazing or whitening during cold storage, delivering strong shelf appeal. The neck finish remains tough at low temperatures, so capping won't crack or deform the finish.

Pharmaceutical And Health Product Bottles

Suitable for syrup bottles, vitamin bottles, and other liquid health products. The thread profile mates consistently with tamper-evident closures, holding steady torque without loosening. Made from pure, uncontaminated PET resin to protect product integrity.

Daily Chemical Packaging

Works for shampoo, body wash, hand soap, and other personal care bottles. The finished bottle resists impact and breakage. The smooth thread profile operates cleanly with no sticking or stripping, delivering a consistent user experience through repeated open-close cycles.
