LDPE Shanghai Petrochemical GB030D
LDPE Shanghai Petrochemical GB030D Resin
Material Introduction: LDPE Shanghai Petrochemical GB030D is low‑density polyethylene specially developed for Blow‑Fill‑Seal (BFS) aseptic filling technology. It features high cleanliness, favorable optical performance and excellent processability.
Main Applications
GB030D is dedicated BFS (Blow‑Fill‑Seal) special resin for blow‑fill‑seal integrated aseptic filling process for high‑end applications.
Pharmaceutical packaging: inhalant bottles, eye‑drop bottles, injection vials and oral‑liquid bottles. Direct contact with pharmaceuticals requires ultra‑high cleanliness, low‑extractable property and good chemical compatibility.
Medical beauty & cosmetic packaging: containers for hyaluronic‑acid and similar products, demanding high safety and material purity.
Performance Parameters
| Performance Category | Test Item | Reference Data / Unit | Reference Test Method | Remarks & Interpretation |
|---|---|---|---|---|
| Basic Properties | Density | 0.920 g/cm³ (typical LDPE range) | ‑ | Typical density range for LDPE. |
| Melt Flow Rate (MFR) | Data to be confirmed, subject to official TDS | ‑ | Estimated within blown‑film‑suitable range according to BFS blow‑molding application. | |
| Mechanical Properties | Rigidity | Relatively high | ‑ | Provides proper structural support for finished packaging containers. |
| Optical Properties | Transparency | Good | ‑ | Facilitates foreign‑matter inspection during filling process for quality control. |
| Cleanliness | Hexane Extractables | Average value:1.4 % (typical level for Shanghai Petrochemical high‑pressure LDPE) | ‑ | Core advantage of low extractables. Minimizes substance migration into pharmaceuticals to guarantee drug safety and stability. |
| Hygiene & Safety | Certifications | Compliant with US FDA, EU RoHS and other authoritative standards | ‑ | Qualifies the resin for pharmaceutical and food‑contact packaging applications. |
Processing Parameters
| Process Stage | Key Considerations |
|---|---|
| Plasticizing Temperature | Adopt relatively low temperature under sufficient plasticization, balanced flowability and melt strength, to reduce thermal degradation and low‑molecular‑substance migration. |
| Blow‑molding Pressure & Time | Determines wall‑thickness distribution and forming quality of containers. |
| Mold Temperature | Affects cooling rate, surface finish and crystallinity, further influences final mechanical performance. |
| Ambient Requirement | BFS production shall be performed under Class‑A clean environment (ISO Class 5 or superior) to maintain aseptic condition. |
