In the field of veterinary drug safety, the sealing defects of prefilled syringes can directly lead to drug failure, cross contamination and even brand reputation crisis. As an industry benchmark with more than 20 years of deep cultivation in pharmaceutical packaging, Xinfuda Pharmaceutical Packaging Co., Ltd. provides veterinary pharmaceutical companies with zero leakage risk prefilled syringe solutions with its R&D system and strict quality control that meet global standards. The following is a key practical guide to ensure sealing:

Key 1: Compliance sealing components-Xinfuda's global certification advantage

Carefully selected materials: Xinfuda's sealing components (pistons/rubber plugs) are 100% compliant with YBB00112004-2015, ISO 11040 and USP Class VI standards, and have passed extreme environment verification from -40℃ to 60℃.

Technical guarantee: The three-layer composite sealing structure and medical-grade bromobutyl rubber are used to ensure that drugs are isolated from oxygen and microbial invasion during transportation and storage.

Key 2: Dynamic sealing system - patented push rod-piston matching technology

Breakthrough of industry pain points: Xinfuda's self-developed piston anti-flip slot design eliminates the risk of piston falling off during injection.

Customer verification support: Provide ready-to-use test kits, customers can verify the sealing through simple operations:

Infuse liquid → push and pull the push rod at a uniform speed → observe the leakage point (barrel wall/push rod connection) → record the pressure threshold

Key 3: Full-dimensional sealing verification - Xinfuda laboratory data endorsement

Each batch of Xinfuda products passes three rigorous experiments and provides authoritative test reports:

Bacterial invasion test: 14-day microbial challenge test, leakage rate ≤0.01%

Saturated salt water corrosion test: simulate the high-salt environment of sea transportation, and the material dissolution complies with EP 3.2.9 specifications

40℃/75%RH accelerated aging experiment: 24 months of equivalent stability data support

Why do veterinary drug companies choose Xinfuda?

Sealing failure = drug failure + brand crisis. How to avoid these? Choose us, Xin Fuda's full-process sealing control system, from the molecular structure of the material to the terminal injection action, establishes a five-layer protection barrier for veterinary drug safety.
