3D Bags for Capsule Packaging & Transport.
Empty hard gelatin and HPMC capsules require clean, contamination-free, and space-efficient packaging to maintain their integrity during storage and transportation. 3D gusseted bags, also known as cube-shaped liners, are widely used in this application due to their structural and hygienic advantages.
3D bags are designed to expand into a cubic or box-like shape, allowing them to conform precisely to the dimensions of plastic bins, HDPE containers, or outer cartons. This form factor:
- Optimizes space utilization during storage and shipping
- Minimizes the risk of capsule deformation or breakage
- Provides a smooth internal surface for easy loading and discharge
These bags are typically manufactured using LDPE, cleanroom-grade materials, or multi-layer laminates depending on the required barrier properties. Heat sealing or tamper-evident closures may also be used to ensure product safety and compliance with regulatory hygiene standards.
3D bags are commonly used by capsule manufacturers, formulation plants, and contract packaging units for bulk capsule handling before final filling and bottling.
