HDPE Non-woven Fabrics Active Carbon Sachet for Oral Solid Preparation

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

The active carbon is a kind of porous substance which is mainly used to absorb the gases in the packaging container.

HDPE non-woven fabrics made with HDPE as the main raw material crank out 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.
