SUZHOU, China – June 5, 2026 – Suzhou Swellder Plastic Co., Ltd. (Swellder), a professional manufacturer specializing in medical and high‑end thermoformed packaging, today announced the release of its new Medical‑Grade PETG Precision Storage Box.
Designed for both medical device accessories and premium storage applications, the product combines superior material science, advanced thermoforming technology, and full compliance with China's medical device standards (GB/T 16886 biocompatibility, GB/T 19633 sterile barrier).
Crystal Clear, Rounded Edge, Medical‑Grade Certified
The storage box is thermoformed from imported medical‑grade PETG (e.g. Eastman Eastar™ or SK SKYGREEN®). PETG offers glass‑like clarity (transmittance ≈90%, haze <1%), high impact resistance (comparable to polycarbonate), excellent chemical resistance, and anti‑yellowing properties. The material is BPA‑free and has passed cytotoxicity, sensitisation and irritation tests according to GB/T 16886.
Aerospace Aluminium Mirror Mold & Thermoforming Excellence
What sets this storage box apart is the manufacturing process. Swellder uses a 7075 aerospace aluminium mold with a mirror polish. Through precision vacuum thermoforming, the heated PETG sheet is uniformly drawn onto the mold surface, resulting in:
Seamless, one‑piece construction (no parting lines, no burrs)
Perfectly replicated mirror finish and extremely smooth inner/outer surfaces
Consistent wall thickness (0.25 – 1.5 mm) and stress‑free curved edges
No post‑trimming sharpness – the edge is naturally rounded and jade‑like to touch
This thermoforming process allows faster tooling development, lower mould costs, and excellent repeatability compared to injection moulding – especially for thin‑walled, transparent, large‑surface products.
Meets China Medical Device Access Requirements
As a medical device accessory / sterile packaging component, the PETG storage box fully supports NMPA registration. Key certifications include:
| Standard | Description |
|---|---|
| GB/T 16886 | Biocompatibility (cytotoxicity, sensitisation, irritation) |
| GB/T 19633 | Sterile barrier for terminally sterilised medical packaging |
| ISO 13485 | Medical devices – Quality management systems (production under certified system) |
| Cleanroom | Manufactured in Class 100,000 / 10,000 cleanrooms, with particle and bioburden control |
Complete compliance documentation (DoC, test reports) is available to assist customers with NMPA registration.
