  • HDPE Non-woven Fabrics Desiccant Sachet for Oral Solid Preparation

    CNPPA 2020/04/26 11:23:02

    The HDPE non-woven fabrics desiccant sachet specified in this standard is composed of desiccant and HDPE non-woven fabrics sachet. It is suitable for oral solid preparation.


    The desiccant refers to the material that can remove moisture in the moist material, such as silica gel and molecular sieve etc., reduce the humidity in the drug packaging container via adsorption of water vapor in the drug packaging container within the specified time, and maintain for a period of time. The variety of desiccant includes: silica gel, molecular sieve and mixed desiccant (such as silica gel: molecular sieve 4: 6)。


    HDPE non-woven fabrics are made with HDPE as the main raw material via the non-woven production process. They have multilayer continuous physical structure and balanced physical properties. Antistatic agent and fluorescent whitening agent must not be used. According to different requirements, it is necessary to study and evaluate the physical and chemical properties of HDPE non-woven fabrics, material specifications (mass per unit area), material cleanliness, particulate contamination, floc falling level, waterproof permeability, particle barrier, tensile strength, tear resistance, rupture resistance and surface performance etc.


    The HDPE non-woven fabrics materials specified in this standard include glue-coated materials and non-glue-coated materials, which shall not release substances sufficient to cause health risks (see GB/T 16886.1 for biological evaluation and test). Where the material is coated with glue, the continuity of the coating shall be assessed. The sachets usually shall be made via the electric heating sealing process for glue-coated materials, and shall be made via the ultrasonic sealing process for non-glue-coated materials.


    HDPE non-woven fabrics desiccant sachet for oral solid preparation must be produced in the environment adaptive to the production environment of corresponding pharmaceutical, and should preferably be produced in the production environment with the relative humidity below 50%.


    HDPE non-woven fabrics desiccant sachet for oral solid preparation shall be produced via the process to avoid the possible contamination of desiccant’s raw material to desiccant sachet.
