Precision Customization, A Professional Choice
PRODUCT OVERVIEW & CORE VALUE
Our PET preforms serve as the critical foundational component in the high-end liquid packaging supply chain, specializing in providing professional and customized packaging solutions for liquor, edible oils, and premium consumer goods. Manufactured from 100% virgin, food-grade PET resin, our preforms exhibit exceptional optical clarity, mechanical strength, and gas barrier properties, ensuring the long-lasting preservation, safety, and reliability of your contents.
Through precision injection molding technology and stringent dimensional control, our preforms guarantee not only a high blow-molding success rate and production efficiency but also deliver crystal-clear visual appeal and outstanding shelf presence for the final containers. We understand the diverse packaging requirements across different industries. Therefore, we offer a comprehensive range of standard neck finishes from 27mm to 72mm and are committed to becoming your reliable partner in packaging innovation through in-depth customization.
DETAILED TECHNICAL SPECIFICATIONS & MATERIAL SCIENCE
Standard Model: 32mm for Edible Oil & Liquor
Neck Finish: Outer Diameter (O.D.) 32.00mm ±0.05mm | Inner Diameter (I.D.) 27.50mm ±0.05mm
Clarity: Haze < 1.5%, delivering a crystal-like transparency.
Strength: Tensile Strength ≥ 75 MPa, ensuring integrity during blow-molding and transportation.
Barrier Property: Excellent CO₂ and O₂ barrier, extending product shelf life.
Reinforced Neck Ring: Patented design ensures a hermetic seal with tamper-evident or screw caps and consistent capping torque.
Gradual Wall Thickness Profile: Scientifically optimized to ensure uniform strength across all parts of the blown bottle (especially shoulders and base), preventing deformation.
Smooth Inner Surface: Facilitates high-speed filling and minimizes liquid residue.
Full Range of Neck Finishes (Customizable on Demand)
We offer flexible manufacturing solutions to meet your diverse container development needs:
Small Neck Series (27mm, 32mm, 36mm): Ideal for premium packaging of Baijiu (Chinese liquor), high-end edible oils, oral solutions, etc.
Medium & Large Neck Series (46mm, 62mm, 69mm, 72mm): Suitable for wine, large-volume edible oils, juice drinks, laundry detergents, cosmetics, and more.
IN-DEPTH CUSTOMIZATION SOLUTIONS
We believe outstanding packaging is integral to a brand's story. Our customization services cover the entire process from concept to finished product:
Precise color matching using PANTONE® color codes or based on your physical samples.
Capable of formulating transparent tints, pearlescent effects, frosted finishes, and other special visual effects.
Structure & Function Customization:
Weight & Capacity Optimization: Precisely calculate and recommend the optimal preform weight based on the target bottle's capacity and blow-up ratio, helping you balance cost and performance.
Special Neck Design: Support custom shapes, enhanced threads, vacuum seal bases, etc., to meet functional packaging needs.
Multi-layer Co-injection Technology (Optional): Provide sandwich-structured preforms with EVOH or other barrier layers for products requiring extreme barrier performance (e.g., juice, beer).
Requirement Consultation → Design & Quotation → Mold Development/Modification → Small-Batch Sampling (Samples Provided) → Performance Testing & Approval → Mass Production & Delivery.
APPLICATION SCENARIOS & SOLUTIONS
Premium Liquor (32mm, 27mm):
Pain Points: Requires high clarity to showcase the liquid, absolute leak-proof sealing, and a premium bottle texture.
Our Solution: Utilizes high-clarity PET material combined with a precision 32mm neck finish and anti-oxidation process to ensure sealing integrity. Preform design supports blowing thick-walled bottles for a premium feel. Edible Oil (32mm, 36mm, 46mm):
Pain Points: Needs to prevent oil oxidation, drip-free pouring, and good oil resistance.
Our Solution: Provides preforms with excellent oxygen barrier properties. Precise inner diameter control enables clean filling. Material complies with food contact safety standards for fats and oils.
Cosmetics & Home Care (62mm, 69mm, 72mm):
Pain Points: Packaging requires unique colors and shapes, with high demands for content compatibility.
Our Solution: Full-color customization capability, supporting matte, pearlescent finishes, etc. Offers chemical compatibility testing support to ensure packaging stability.
Quality is the cornerstone of our brand. We have implemented a digitalized quality management system throughout the entire process:
Incoming Quality Control (IQC): Testing key parameters (viscosity, color, moisture content) for every batch of PET resin.
In-Process Quality Control (IPQC): Real-time monitoring of injection molding parameters (temperature, pressure, cycle time). Sampling every 2 hours for weight, dimensions, and visual inspection.
Final/Outgoing Quality Control (FQC/OQC): 100% weight sorting before shipment to eliminate defects. Batch sampling for lab tests, including burst pressure and seal integrity tests.
Traceability: Each production batch carries a unique identifier, enabling full traceability from raw material to finished preform.
We solemnly commit to providing our clients not just products, but stable and reliable quality assurance.
We look forward to partnering with you to transform your packaging ideas into market competitiveness!
