VCI 3D Bags and Oversized VCI Machinery Bags

Large-format VCI bags converted to your length, width and height so multimetal VCI film works inside a closed free volume. Built for metal parts, machines and export packing where ordinary PE is not the corrosion answer. Film thickness 25 to 300 microns.

What a VCI 3D bag is on this site

A VCI 3D bag is a form-fit bag or cover made from VCI film so vapour-phase corrosion inhibitors can protect metal inside a sized free volume. BENZ supplies multimetal VCI film as sheets, rolls, 2D bags and 3D bags. This page covers large-format conversion. Full VCI chemistry and film grades are on the VCI film product pages.

For film grades and how VCI works, open VCI film products and what is VCI packaging. PE geometry without corrosion chemistry: custom 3D bags. Enhanced moisture-barrier protection: barrier 3D bags.

For multimetal VCI film grades, chemistry and product options, use the linked VCI film product family. This page focuses on large-format 3D conversion, sizing and enquiry rather than restating full VCI science.

How to measure

Measure maximum packed L, W and H including skids and protrusions. Plan how the free volume will be closed: heat seal, tape or other method the packing team actually uses. VCI needs a practical enclosure, not a bag left open on a dirty wet part. Photos help for irregular machines. If structure is required, keep the cover conversation here and the crate conversation on export packing pages.

Common failure modes: bagging wet dirty metal; leaving free volume open; using plain PE when corrosion is the risk; ordering barrier film when VCI free volume was the real need, or the reverse. Fix cleanliness, closure and dimensions before debating film brands.

Common questions

What is a VCI 3D bag?

A three-dimensional bag or cover made from multimetal VCI film so vapour-phase corrosion inhibitors work inside a closed free volume sized to your L x W x H. Also called large VCI bags or VCI machinery bags.

How is this different from ordinary PE 3D bags?

Geometry can look similar. The film is different. VCI film is for enclosed corrosion protection of metals. Plain polyethylene is for dust and handling. Use custom 3D bags for PE-only geometry jobs.

Do I still need clean dry metal and a good seal?

Yes. VCI is not a substitute for dirty, wet metal or an open bag. Close free volume as the packing method requires and keep surfaces reasonably clean and dry before bagging.

What film thickness can you supply?

BENZ can supply film constructions from 25 to 300 microns, selected for free-volume size, handling, metal type and storage or export duration.

When should I use barrier film instead?

When the main risk is moisture and gas ingress over a long sealed pack rather than vapour-phase corrosion control alone. See barrier 3D bags and barrier packing method pages.

What do you need for a quote?

Maximum packed L x W x H, metal types if known, storage or export weeks, quantity, photo for irregular machines, and whether desiccant or barrier layers are also planned.

Need a VCI bag for a real free volume?

Send your dimensions and metal context. We will quote a VCI 3D format and point you to the right film grade.
