Answer：
Capsules are traditionally enclosed within hard or soft shells, with hard-shell capsules typically being filled with powders and soft-shell capsules being filled with oil-soluble materials. However, scientists have now developed a new “liqu-sealing” technology to replace the more difficult-to-absorb soft-shell capsules. Liqu-sealing capsules can be filled with oil-soluble materials for increased absorptivity, while the transparency of these new-style capsules allows the consumer to check instantly the appearance and quantity of the contents contained within the capsule. This not only increases the quality and value of a product, but also leads to increased consumer confidence. SUNLIFE also adopts capsule-sealing technology to apply single- or multiple-layer coatings to prevent two-piece capsules from separating, and to provide increased product safety and moisture resistance. Liqu-sealing technology is highly valued in the global biotech industry and also complies with US FDA regulations on capsule sealing processes for non-prescription drugs.

BENEFITS OF LIQU-SEALED CAPSULES:
1. High transparency
2. High heat tolerance prevents deformities and qualitative damage
3. Suitable for liquids/powders with strong odors or that are prone to oxidization
4. More difficult to counterfeit
5. Product elements are more stable
6. Inhibits encroachment of moisture and oxygen (which can affect active elements)
APPLICATIONS
1. Oil products (e.g. Vitamin E, evening primrose, and fish oil)
2. Suspended substances (e.g., herbal extract liquids)
3. Essential extract powders (e.g., grape seed extract and enzymes)
4. Herbal extract powders (e.g., Ginsenoside extract)
5. Pellets
