HDPE/COEX Bottle 500mL ø38mm Round with Single Ring – Standardized Synchronous Packaging Solution
In the context of optimizing production and packaging workflows, enterprises are constantly seeking a packaging solution that offers high flexibility and cost efficiency for label design, while ensuring absolute safety for the liquids inside. The 500mL ø38mm Round HDPE/COEX Bottle with Single Ring (HDPE/COEX Bottle 500mL ø38mm Round With Single Ring) from P H L Plastics is a strategic choice that fully meets all the above criteria.
Depending on the physicochemical characteristics of your product, businesses can flexibly choose between two optimal lines: the standard HDPE Bottle line with high mechanical durability, or the breakthrough 3-layer COEX Bottle line (featuring an inner barrier layer of EVOH material that delivers outstanding solvent resistance, anti-corrosion properties, and superior anti-cross-permeation capabilities).

2. Key Features
This product scores highly with manufacturers thanks to its smart mechanical improvements, which completely resolve common issues encountered during labeling and capping:
- Classic Round Smooth Design Combined with a Smart Single Base Ring: The smooth round bottle shape maximizes the visible surface area of the label from all angles. Notably, the improved design integrates a raised ring near the base of the bottle that acts as a fixed support ridge, ensuring the automated labeling process is precise and preventing the label from slipping, misaligning, or wrinkling.
- Tamper-Evident (Guarantee) Neck for High Security & Measuring Cup Utility: The tamper-evident neck system comes with a smart locking ring to prevent counterfeiting and imitation. The ø38mm opening expands the opportunity to integrate an external measuring cup over the cap, increasing convenience and utility for the end consumer.

- Perfect Synchronization Solution (Compatible with PET Bottle System): This is the most valuable advantage for factories that package goods using diverse materials. The 500mL HDPE/COEX bottle shares the exact same technical specifications and ø38mm neck size as P H L's standard PET bottle line. This allows businesses to use a single label template and one uniform cap specification, maximizing savings on material management costs and synchronizing automated packaging lines.

3. Ideal Practical Applications
Thanks to the outstanding protection properties of its HDPE or COEX (EVOH) structure, the 500mL ø38mm bottle is widely utilized across the following sectors:
- Agricultural Chemicals: Serves as the ideal packaging for liquid foliar fertilizers, micronutrient fertilizers, crop protection products, and flowering/fruiting stimulants without any concern regarding shell deformation or chemical leaching.
- Veterinary, Aquaculture & Livestock Chemicals: Specifically used for containing liquid veterinary medicines, biological formulas for pond water treatment, concentrated probiotics, or various types of alcohols and livestock facility disinfectants.
- Other Industrial Sectors: Its robust chemical resistance helps safely store industrial printing inks, water-based paints, textile dyeing auxiliaries, technical lubricants, or long-term chemical laboratory samples.
