Product Specification

Product specification in any development can be a very lengthy process, we help our customers to shorten the process by our knowledge of the manufacturing process, the application technology, regulatory requirement, functionality & marketing concerns.

Quality Agreement

Quality Agreement

Balancing the interest of the users and the manfacturers is always a challenges facing any quality negotiation. We mediate professionally to seek the common goals that befit both party's imperatives in high standard and compliance.

Quality Agreement

Registration CDE/China

Registration CDE/China

We register all our primary packaging material with CDE for as early as CFDA set up the platform.  The task is still going on year by year for new products registration, and we maintain the files active and update annually.  We manage also changes to the CDE files and give support to affected clients for the Change.

Surface Treatment

Surface Treatment

On finished glass container, we can further treat the bottles for certain desired effect:

Hot Treatment

Hot treatment on extermal surface of the glass vials:  it is an external spraying of SnO2 to impart extra strength to the glass bottles against abraision, vibration, shocks and stress from logistic handling and pharmecutical process.  It reduces breakage and bump checks.  The spraying is done at hot end in the glass manufacturing process, it is then call Hot Treatment. 

Cold Treatment

Cold treatment on external surface of the glass vials: it is an external spray coat of non ionic surfactant: SIMULSOL, α-glycols, PE monostearate. It enhances the gliding property of the glass surface, so that the glass vials can resist stress from squeezing and squambling on feeding line, turning table.  Reduce breakage and bump checks.  The spraying is done just after the annealing lehr closed to the cold end of the glass manufacturing process, it is then called Cold Treatment.

Siliconisation

Siliconisation

Siliconization is realized with an aqueous emulsion of a polydimethysiloxanic oil, conforming to all pharmacopeias, sprayed inside the vials. The silicone film is fixed onto glass through the annealing lehr. All vials from 5ml to 1L, clear or amber, Type I, II or III glass may be siliconized. To maintain the quality of the coating, siliconized vials should be stored in dry condition and at moderate temperature. Silicone breaks down at temperature over 350° C.

Major qualities products for pharmaceutical:


  • It provides a protective layer useful for fragile molecules, further minimizing the interactions between the product and the container
  • It prevents high viscosity infusions from sticking to the internal surface of the vials giving them a perfect transparency
  • Finally, due to its hydrophobic properties, the silicone coating ensures a higher restitution rate down to the last drop of product
  • Compatibility tests between the product formulation and the siliconized vials have to be performed. The resistance of the silicone coating depends on the chemical structure of the pharmaceutical product, as well as its dissolving power on silicone.
