In the chemical and biotech packaging industries, concentrated solutions with gas-evolving properties always demand specialized packaging solutions to prevent bottle deformation, bloating, or leakage. The 150mL ø50mm Round 2-Ridge Rounded-Shoulder HDPE/COEX Bottle from P H L Plastics is the perfect answer. Combining chemical-resistant resin materials, a smart 2-ridge labeling design, and compatibility with ø50mm degassing cap systems, this product ensures absolute safety and high aesthetic value for your brand.
Specialized 150mL Capacity for Concentrated Liquids: The 150mL capacity range is specifically engineered for high-concentration active ingredients, small-dosage applications, or premium product samples. It is the smallest volume in our large ø50mm neck collection—allowing seamless integration with specialized vented degassing caps that equalize internal pressure and prevent bottle collapsing or bloating caused by off-gassing chemicals.
Two-Ridge Rounded-Shoulder Design – Distinct & Easy to Label: The bottle body features a smooth, rounded-shoulder silhouette that remains structurally sturdy. The dual raised ridges at the upper shoulder and lower base act as a protective framing boundary, keeping automated labels aligned, perfectly flat, and safe from scuffing or peeling during transit.
Part of a Comprehensive 2-Ridge Rounded-Shoulder Collection: This product inherits the exact design language of our complete 2-ridge rounded-shoulder series, which includes capacities of 300mL – 550mL – 1000mL. This consistency allows enterprises to easily build a synchronized product line, enhancing professional brand recognition on the shelf.
Chemical-Resistant HDPE/COEX Material: Available in standard virgin HDPE or multi-layer COEX (integrated with an EVOH barrier layer) to deliver outstanding chemical resistance, zero permeation, and high mechanical impact strength.
Thanks to its compatibility with vented degassing caps and chemical-resistant surface, the 150mL ø50mm bottle is particularly suited for off-gassing liquids or formulations requiring strict preservation:
Agricultural Chemicals: Highly suitable for packaging concentrated biological foliar fertilizers, liquid micronutrients, organic composting inoculants, crop protection chemicals, or growth stimulants prone to fermentation and gas buildup.
Veterinary, Aquaculture & Livestock Chemicals: Specifically used for containing concentrated aquaculture probiotics, bottom-water treatment formulas, facility disinfectants, or liquid vitamins and minerals for livestock and poultry.
Other Industrial Sectors: Serves as ideal storage packaging for laboratory testing chemicals, concentrated industrial cleaning formulas, essential oils, specialized adhesives, or long-term biological samples.
The 150mL ø50mm Round 2-Ridge Rounded-Shoulder HDPE/COEX Bottle is a benchmark combination of intelligent industrial design and safety protection for gas-evolving formulations. Investing in standardized, compliant packaging not only completely resolves bottle deformation challenges but also reinforces your brand's reputation and quality in the market.
With over a decade of experience, P H L proudly stands as one of Vietnam’s leading manufacturers and suppliers of plastic bottle packaging.
