Low moisture content:5％～8％，strong resistance to moisture absorption，keeping the content from easy caking and the shell itself from easy deformation, embrittlement or hardening．

High stability free from risks of cross-linking reaction or mutual interaction: Since HPMC is a derivative of fibers．It’s free from cross-linking reaction with the amino acid in gelatin

Simple storage conditions:rare crushing in low temperature(30％RH, crushing rate=2.1％)and good stability in high temperature(80℃, capsule variation<1.0％)

Nice coating performance:The capsules have a nice affinity with most high molecular materials．easy for the coating materials to adhere uniformly．It’s suitable for the production of sustained-release coating capsules．

Unified standard allowing a better compatibility:It applies the standard of State-promulgated Pharmacopoeia, and the shape，size，appearance and production procedures are the same with gelatin capsules，so there’s no necessity to change the equipments or accessories．
