Direct Factory Raw Materials & Finished Absorbable Sponges (50–320 Bloom | Custom Mesh & Porosity)
In modern intraoperative surgical management, immediate control of arterial, venous, and capillary oozing is crucial for reducing patient morbidity, minimizing transfusion requirements, and shortening operating times. Absorbable Hemostatic Gelatin Sponges and Powders represent a cornerstone of biological wound management. Derived from purified collagenous biopolymers (typically bovine hide, bovine bone, or marine collagen matrices), medical-grade gelatin provides a sterile, water-insoluble, porous structural framework designed to arrest hemorrhage where traditional ligation is impractical or ineffective.
When applied to bleeding tissue, the micro-porous structure of gelatin acts as a physical scaffold. As blood permeates the matrix, platelets come into immediate contact with the denatured collagen triple-helix fragments. This contact induces platelet adhesion, shape change, and degranulation—releasing adenosine diphosphate (ADP), thromboxane A2, and serotonin. The localized concentration of clotting cascade factors accelerates the conversion of prothrombin to thrombin, ultimately yielding an insoluble cross-linked fibrin clot embedded directly within the absorbable gelatin structure.
Complete tissue resorption occurs via endogenously secreted proteolytic enzymes (primarily collagenases and lysosomal hydrolases) within 2 to 4 weeks, leaving zero permanent foreign body residue or long-term granulomatous tissue reaction.
Partnering with a specialized OEM Hemostatic Gelatin Factory requires absolute confidence in quality management systems, batch-to-batch reproducibility, cleanroom controls, and regulatory dossier completeness. Operating under audited ISO 13485:2016 quality management frameworks and certified under EU MDR (Regulation 2017/745) protocols, our production infrastructure bridges the gap between high-volume biopolymer extraction and ultra-precise medical device assembly.
Every gelatin batch undergoes quantitative testing for pore size distribution, fluid absorption capacity, and gel strength, exceeding USP/EP minimum thresholds by at least 10% to guarantee intraoperative reliability.
We provide complete technical files, biocompatibility data (ISO 10993), viral clearance documentation, and stability studies necessary for rapid global product registrations.
Offering bovine skin gelatin, bovine bone gelatin, and halal/kosher marine (fish skin) gelatin options to meet cultural, ethical, and clinical regional market preferences.
The manufacturing process of surgical gelatin sponges demands strict environmental controls. Our cleanrooms (Class 10,000 / ISO Class 7) maintain controlled ambient temperature and humidity to regulate the foaming and thermal cross-linking kinetics of the gelatin solution.
Selecting the optimal gelatin specification requires evaluating physical, chemical, and microbiological metrics. The Bloom strength (measured via standard Stevens/FIRA gelatinometer testing) dictates the gel rigidity, mechanical resilience during surgical handling, and water absorption capacity.

Different surgical specialties demand specific physical formats, densities, and degradation profiles. As an expert contract manufacturer, we tailor density profiles, sheet dimensions, and powder particle sizes to align with specialized operative procedures.
For visceral oozing, liver resection, and bowel anastomoses, high-density Bovine Skin Gelatin Sponges (200–250 Bloom) provide superior structural integrity. They can be applied dry or saturated with sterile saline solution or thrombin solution to immediately form a pliable hemostatic compress over broad parenchymal surfaces.
Neurosurgical applications require ultra-low particulate shedding and micro-porous consistency to prevent pressure necrosis on neural tissue. Micro-porous Bovine Bone Gelatin Sheets offer precise tactile feedback, conforming effortlessly to brain cavities and spinal dura margins without excessive expansion.
Pre-cut dental cubes (10 × 10 × 10 mm) packaged in sterile blister cards are specifically formatted for post-extraction tooth socket hemostasis. The high absorption velocity rapidly stabilizes alveolar clots, mitigating alveolar osteitis (dry socket syndrome) while supporting bone tissue regeneration.
Compressed, low-density gelatin tamponades expand gently upon contact with mucosal secretions in nasal septum procedures and tympanoplasty. The controlled degradation profile allows natural mucosal ciliary clearance without painful manual packing removal.
The global marketplace for absorbable hemostatic agents is undergoing rapid evolution driven by regulatory tightening, cultural demands, and technological innovation. B2B procurement managers and medical device brand owners must adapt to three key industry shifts:
With increasing demand across Middle Eastern, Southeast Asian, and European healthcare networks, buyers are increasingly sourcing Fish Skin Gelatin (Marine Collagen). Marine-derived gelatin eliminates risks associated with Transmissible Spongiform Encephalopathies (TSE/BSE) while opening market access in regions with strict religious dietary compliance (Halal & Kosher).
Premixed and dual-syringe flowable gelatin matrix kits (combining gelatin powder with active recombinant thrombin) are gaining market share over standard dry sponges. Contract manufacturing factories are investing heavily in dual-chamber delivery devices and micronized gelatin powder processing facilities.
The transition from EU MDD to EU MDR (2017/745) has elevated Class III medical device standards, requiring rigorous clinical evaluation reports (CER), post-market clinical follow-up (PMCF), and comprehensive raw material origin traceability. Distributors are consolidating vendor lists, favoring OEM factories that provide turnkey MDR-certified dossiers.
When sealed in validated double-barrier aluminum foil or blister primary packaging, medical-grade absorbable gelatin sponges maintain a 5-year shelf life. They should be stored in cool, dry conditions (< 25°C) away from direct solar radiation and moisture.
Yes. Our OEM capabilities encompass custom mold design, pore size customization (50 to 300 µm), specialized shapes (cubes, strips, tampons, powders), multi-language packaging artwork, and private-label box branding under your company name.
All bovine hides and bones are sourced exclusively from certified herds in TSE/BSE-free geographic regions. Substrates undergo rigorous alkaline processing and hot-water extraction, backed by EDQM Certificates of Suitability (CEP) and full veterinary health certificates.
Standard bulk gelatin powder MOQs start at 25kg per bag. For custom-cut sterile gelatin sponges packaged under private labels, standard initial production runs start at 5,000 to 10,000 units depending on box dimensions and packaging complexity.
Our primary manufacturing cleanrooms operate under ISO 13485:2016 quality management systems, possess CE marking under EU MDR 2017/745, and maintain full compliance with US FDA 21 CFR 820 Quality System Regulations.
While ORC relies on low pH carboxyl groups to form a dark clot mass, gelatin operates at neutral pH, making it non-irritating to sensitive neural tissue and compatible with topical thrombin solutions. Gelatin also offers higher fluid swelling capacity.
We supply full Technical Files (STED format), ISO 10993 biocompatibility test reports, viral inactivation validation data, stability testing summaries, and Certificate of Analysis (CoA) documentation required by regional health authorities.
Accelerate your medical device brand with ISO 13485 cleanroom production, 1.1× USP validated quality, and complete EU MDR technical dossier support.
