For Southeast Asian manufacturers looking to sell on Alibaba.com in the pharmaceutical packaging sector, understanding capsule material configurations is the foundation of successful product positioning. The empty capsule industry revolves around two primary material types, each with distinct characteristics, cost structures, and target markets.
Gelatin Capsules represent the traditional standard, derived from animal collagen (typically bovine or porcine sources). They account for approximately 65-73% of the global empty capsule market [1][2]. Gelatin capsules offer excellent dissolution properties, established manufacturing processes, and competitive pricing - making them the default choice for conventional pharmaceutical and supplement applications.
HPMC (Hydroxypropyl Methylcellulose) Capsules, also known as vegetarian or plant-based capsules, are manufactured from plant cellulose. While currently holding a smaller market share, this segment is experiencing the fastest growth rate at 10.25% CAGR through 2031 [1]. HPMC capsules appeal to vegetarian/vegan consumers, religious groups with dietary restrictions (Hindu, Muslim, Jewish), and premium supplement brands seeking cleaner label positioning.
Other Material Options include pullulan capsules (fermented from tapioca), cellulose capsules, and modified starch capsules. These represent niche segments but may be relevant for specific buyer requirements or regional preferences.
