Box liners, flat & roll bags
Inner bags for cartons and outer packs, helping separate the contents from the box surface with dimensions matched to the load.

Box liners
Box liners should fit the base, height and required fold-over allowance. Flat or gusseted constructions can be considered for convenient insertion, filling and closure.
- Create a separating layer between goods and the outer pack.
- Support product containment and carton-packing operations.
- Match the box, filling method and closing process.
Example applications
Industrial cartons · Raw materials · Bulk goods · Food applications on request
Example: a bulk-goods packer needs liners that fit cartons with sufficient allowance for folding or closing. Dimensions are checked through actual liner-insertion and filling trials.

Flat & gusseted poly bags

- Contain and portion products in the required format.
- Use gussets where additional expansion is needed.
- Add vents or converting features when appropriate.
Example applications
