A Note on Weight Selection
The 38mm neck finish is used across a wide range of preform weights. Common market weights include 17g, 28g, 30g, 32g, 36g, 43g, 55g, and 75g -- and the right choice depends on your specific bottle volume, bottle shape, filling method, and cap system.
We recommend confirming the weight with our technical team before placing an order. Share your bottle design, target capacity, and filling type -- we'll help you select the optimal preform to avoid waste and ensure consistent blowing performance.
Common Weight Reference
Typical 38mm preform weights by application -- for reference only. Final weight must be confirmed based on your bottle design.
| Weight | Typical Bottle Capacity | Common Application | Note |
|---|---|---|---|
| 17g | 250ml - 330ml | Small water, juice shots | Lightweight, thin wall |
| 28g | 500ml | Still water, cold fill beverages | Most common weight for 500ml |
| 30g | 500ml - 600ml | Carbonated soft drinks, water | Slightly heavier wall for CSD |
| 32g | 600ml - 750ml | Juice, tea, dairy | Good balance of weight and strength |
| 36g | 1L | Sports drinks, flavored water | Suitable for hot fill at lower temp |
| 43g | 1L - 1.5L | Hot fill juice, tea | Thicker wall for heat resistance |
| 55g | 1.5L - 2L | Large juice, dairy, condiments | Heavy-duty, wide-mouth variants |
| 75g | 2L+ | Bulk beverage, industrial fill | Maximum structural integrity |
* All weights are indicative. Actual preform weight depends on bottle design, wall thickness distribution, filling pressure, and cap torque requirements. Contact our team to confirm the right specification for your project.
Tell us your bottle capacity, filling type, and target weight -- we'll confirm the right spec within 24 hours.

Cap Fit Is Not Guaranteed
by Diameter Alone
Two preforms can both measure 38mm and still be incompatible. Thread profile, pitch, and finish height all affect whether your cap seals correctly -- and whether your filling line runs without stoppages.
Before we quote, we confirm:
-
Your cap type and closure system Screw, press-on, or snap -- each requires a matched neck profile
-
Bottle drawing or existing mold spec Prevents mold mismatch and costly rework after production
-
Filling temperature Hot-fill applications require heat-resistant preform grades
-
Blow molding machine compatibility Reduces sealing problems, leakage risk, and line downtime
Why Choose 38mm PET Preforms?
Engineered for high-volume beverage production -- the 38mm neck standard delivers performance, flexibility, and reliability at every stage of your supply chain.
-
Larger Neck Opening
A 38mm neck gives more space for beverage filling, cap design, and product flow -- reducing bottlenecks on high-speed filling lines.
-
Suitable for More Beverage Types
Widely used for juice, tea drinks, dairy products, sports drinks, and large-volume beverage bottles -- one preform format, broad application coverage.
-
Better for Hot-Fill Projects
For juice and tea drinks, hot-fill preforms can help support higher filling temperature requirements -- maintaining structural integrity where standard preforms fall short.
-
Flexible Weight Design
Different bottle capacities and filling methods need different preform weights. We help match the right gram weight to your bottle design, optimizing material usage and production cost.
-
Stable Sealing Performance
A precise neck finish helps match caps more accurately and reduces leakage during filling, storage, and transport -- protecting product quality throughout the supply chain.
38mm Hot Fill PET Preforms
for Juice and Tea Bottles
For juice, tea drinks, and other hot-fill beverages, the preform must be matched with the filling temperature, bottle mold, and cooling conditions. We support 38mm PET preforms for hot-fill bottle projects -- helping customers reduce deformation risk and improve bottle stability after filling.

Why Neck Size and Fill Temperature Matter
Hot-fill PET preforms are commonly used for juice, tea, and other heat-sensitive beverage packaging. The 38mm neck finish is one of the most widely used specifications in this category. Matching the preform to the correct fill temperature and bottle mold geometry reduces post-fill deformation and ensures consistent shelf appearance.
