As a Premium Essential Oil Capsule, it is available in food-grade gelatin (100% bone glue) and vegetarian HPMC (hypromellose) materials, both free from additives, preservatives, and harmful contaminants. With ultra-low heavy metal content (<20ppm for HPMC, <40-50ppm for gelatin) and a 99.9%+ filling rate, this capsule meets the demands of commercial production, clinical use, and bulk packaging. Certified by ISO9001, HALAL, and COA, it offers exceptional temperature stability (HPMC) and a long shelf life (up to 36 months), making it a top choice for manufacturers, aromatherapists, and wellness brands seeking reliable, high-capacity packaging for essential oils.
Designed for large-dose needs, the 300mg Empty Capsule for Essential Oils eliminates the need for multiple small capsules, streamlining production and user experience. Ideal for bulk essential oil blends, dietary supplements, and commercial formulations, it reduces packaging waste and costs.
With heavy metal content as low as <20ppm (HPMC), the Low Heavy Metal Capsules exceed international safety standards. Rigorous testing ensures no BSE, additives, or preservatives, making them safe for oral use and long-term storage.
Heat-Resistant Capsules (HPMC variant) maintain stability in temperatures ranging from 10-40℃, avoiding brittleness (low temp) or softening (high temp) common in traditional gelatin. The 36-month shelf life (HPMC) and 24-month shelf life (gelatin) ensure product longevity, reducing inventory turnover concerns.
Crafted with tight dimensional tolerances (±0.4mm for length, ±0.015mm for thickness), the High-Filling Rate Empty Capsules deliver a 99.9% filling rate, minimizing product loss during manufacturing. The consistent wall thickness ensures uniform dissolution and reliable dosing.
Supporting Custom Capsule Printing (ring, axial, radial, circumferential) and a wide range of colors (e.g., bright green-bright green, black-blue, orange-orange), the capsules enable brand differentiation. Available in 00# to 4# sizes, they accommodate diverse formulation needs beyond 300mg.
Perfect for large-scale production of essential oil-based supplements, topical treatments, and wellness products. The 300mg capacity aligns with standard dosage requirements for commercial brands, ensuring consistency across batches.
Used by healthcare providers and certified aromatherapists for clinical applications, such as targeted pain relief, respiratory support, or mood regulation. The Medical-Grade Empty Capsules ensure purity and reliability for patient use.
Ideal for enthusiasts creating large batches of essential oil mixtures (e.g., massage oils, diffuser blends, or oral supplements). The leak-proof design preserves potency, while the high capacity suits family or group use.
Supports industrial manufacturers in producing essential oil-infused vitamins, herbal remedies, and functional foods. The capsule’s compatibility with liquid and semi-liquid oils makes it versatile for diverse formulations.

Yes! The capsules feature a secure pre-locked and locked design (length: 22.7-23.7mm locked) that prevents leakage, even with viscous essential oils. The tight seal preserves oil potency and avoids contamination.
Gelatin capsules are stable at 10-25℃ (avoid >25℃ to prevent softening), while Temperature-Stable HPMC Capsules tolerate up to 40℃ without deformation. Both should be stored away from direct heat sources.
The HPMC variant is 100% kosher and halal-compliant, while gelatin capsules are not suitable for Jewish or Islamic diets. All capsules are vegetarian-friendly (HPMC) or traditional (gelatin), with clear labeling for dietary compliance.
Absolutely! We offer four printing techniques: ring printing, axial printing, specified radial printing, and circumferential printing. Custom text, logos, or dosage information can be added for bulk orders, enhancing brand recognition.
