The PET Preform Collapsible Cage supports repeated movement between production sites and downstream bottle factories. Loaded cages travel with PET preforms, while empty cages return through scheduled transport loops. Empty cages are usually collected in designated return areas, while loaded cages remain in shipping or storage areas until dispatch. Some units remain in service for long periods and continue through multiple loading cycles. After unloading, cages are folded and stacked while waiting for the next shipment. Folded empty cages are collected together and returned for the next loading cycle.
Advantages

- Designed for repeated transport cycles between facilities.
- Supports stacking of folded units in return areas.
- Designed for repeated use between preform suppliers and bottle production plants.
- Helps separate loaded and returned containers.
- Folds after unloading for compact storage.
- Stable structure supports repeated handling.
Products Customized
The PET Preform Collapsible Cage can be configured to match different return systems and transport schedules. Label holders and ID plates help operators identify container numbers and shipping information during repeated use. Optional top lids, dividers, and inner PP sheets are available based on product requirements. Reinforced structures are available for applications involving frequent loading, unloading, and forklift movement. Dimensions and loading capacities can be adjusted to fit existing warehouse layouts and transportation equipment.

Application
In returnable industrial packaging systems, the PET Preform Collapsible Cage moves repeatedly between suppliers and bottle production plants. Empty units are collected according to truck schedules and stacked in designated return areas. Loaded cages waiting for shipment and returned empty cages are usually stored in separate areas to avoid mixing. Many cages remain in service for years and are repeatedly used for loading and return transportation. After returning, operators usually check for damaged mesh, bent sections, or missing components before the next loading cycle.

FAQ
Q: How many loaded PET preform cages are typically stacked in the warehouse?
A: Most plants stack loaded cages in 2 to 4 levels. Higher stacking may require reinforced structures. Forklift capacity and total load weight should also be considered.
Q: What do plants do with empty PET preform cages during slow production periods?
A: Empty cages are folded and stacked in designated storage areas. Collapsed units occupy much less space and are kept ready for the next production cycle or return shipment.
Q: What is commonly used to keep PET preforms from contacting the steel wire?
A: Many plants install PP sheets or plastic liners inside the cages. These inserts separate the preforms from the wire structure and help avoid scratches during handling and storage.
