Soft-gel Capsule

Preparations - Soft-gel capsule

In contrast to hard gelatine capsules, soft gelatine capsules are filled with liquid or semi-solid goods. The vast majority of capsules consist primarily of gelatine and plasticisers. They offer better active ingredient absorption of poorly water-soluble active ingredients. The release of the active ingredient can be immediate or delayed. The disadvantage compared to tablets is the more complex production process.

Object-specific challenges

Product features

During production, the two gelatine sleeves are welded together after the core has been enclosed. This creates a welded seam. However, leaking capsules may occur and must be ejected by a inspection system.

Recommended inspection system for the inspection of soft gelatine capsules

The SPECTRA CL colour product inspection is suitable for the inspection of softgels, with which the sub-mixing, size, position and shape of preparations can be checked. If soft gelatine capsules are to be inspected after blistering, scanware recommends the high-resolution Blister Inspection.

Highlights of the colour inspection

  • Very high speed and a variety of analysis tools
    All parameters can be applied simultaneously – at the same high speed
  • The WLED illumination is homogeneous, reproducible and adjustable in 16 brightness levels
  • Best hardware and comprehensive software package based on the QNX® real-time operating system
  • The system can be upgraded in software and hardware to high-resolution product inspection at any time
