Explore our top-tier leak-proof plastic bottles and storage solutions, certified for food-grade safety, chemical compatibility, and cosmetic formulation preservation.
From raw material feeding to high-speed blow molding, our automated facility in Taizhou guarantees consistency, precision, and zero-defect output for international enterprises.
Our facility houses 2 domestically leading fully automatic feeding systems. Centralized control eliminates cross-contamination, ensuring that raw PET resins remain dry, clean, and perfectly formulated prior to the heating process.
Equipped with 26 injection blow molding production lines. This methodology ensures uniform wall thickness, seamless bases, and flawless neck finishes which are critical for maintaining leak-proof configurations in high-demand packaging environments.
Backed by 38 injection molding equipment systems, our production floor handles high-cavity molds with high clamping pressure. We guarantee dimension stability across production lots, facilitating airtight closures for bottles and jars alike.
Leakage is the enemy of shelf-life, safety, and brand value. We implement precise physical geometries and polymer selection strategies to address sealing issues at the molecular level.
We calibrate container neck profiles using SPI/GPI standards. By matching screw threads with precise tolerances (within ±0.1mm), we ensure that the capping pressure is distributed uniformly, preventing thread slippage and micro-channel leaks.
From induction-sealed liners and EPE foam sheets to pressure-sensitive adhesives, our bottles are designed to mate perfectly with various liners. This creates a multi-layered barrier against oxygen migration and liquid transport.
Utilizing high-grade PET, HDPE, and PP resins, we control the intrinsic viscosity (IV) of plastics. This optimizes mechanical resistance to stress cracking, ensuring containers remain leak-proof even under cabin pressure variations during air transit.
We have 2 domestically leading fully automatic feeding system, 26injection blow molding production lines, and 38 injection molding equipment to ensure an annual production capacity of 100 million sets of packaging containers. Explore our targeted industries below:

Answers to common engineering, logistical, and customization questions asked by worldwide procurement managers.
We match the inner finish dimensions of the PET neck with precision injection-molded caps. By enforcing exact thread height and lead angles, we ensure a persistent compression seal that handles acidic, salty, and viscous seasonings like soy sauce and vinegars without degrading over time.
Yes. Our PET is 100% non-toxic, food-safe, and complies with FDA requirements. Our automatic centralized feeding systems isolate materials from contaminants, guaranteeing that no chemical migration occurs between the container wall and the food elements stored inside.
We support full OEM and ODM services. From mist sprays and fine pumps to custom transparent colors (like amber or purple HDPE), we configure height, weight, volumetric capacities, and neck threads according to client blueprints.
With an annual output exceeding 100 million packaging sets, our factory manages high-volume supply contracts efficiently. MOQs vary depending on whether the design is standard or customized. Contact our sales department for exact calculations on customized molds.
All containers undergo rigorous vacuum testing and pressure deformation analysis. Our Quality Assurance teams inspect the sealing interface using automated camera inspectors on the line to identify and eject any slight micro-structural defects.
PET provides a high oxygen barrier, superb chemical compatibility, and crystal-clear clarity. This enables customers to view cosmetic colors clearly, while ensuring beverages remain fresh and completely free from off-flavors.
