Seamless capsules with a high degree of freedom in product design.
These seamless capsules are manufactured using the property of liquids to form a spherical shape due to interfacial tension.
The capsule diameters size ranges from as small as 1 mm to as large as 10 mm,
The size of the capsule can be freely set, and the thickness and hardness of the shell can be adjusted.
They can also be mixed and blended into other products as small, granulated capsules.
Features and benefits
-
Flexibility in diameter and shell thickness
Seamless capsules can be produced from 1mm – 10mm in diameter and in several 10s of micrometers – several thousands of micrometers in shell thickness to suit various ingredients and purposes. -
Broad range of dissolving times
Seamless capsules can be designed to dissolve in the body anywhere from several seconds to several hours according to the ingredients’ characteristics. -
Flexibility in product design
Heat-resistant capsules that protect the contents without rupturing the shell even at high temperatures can also be produced, as can capsules that can contain oil-based substances in an aqueous solution. Beverages, lotion, and shampoo are examples of applications.
