What are the storage advantages of PET Preform storage containers?

In many factories, PET preform deformation during storage and stacking is a serious issue that affects blow-molding accuracy. When PET preforms are stacked too high or stored in unstable bins, the bottom layers often deform under pressure. This leads to neck-size deviation, mold-fit failures, and higher rejection rates. To solve this, more manufacturers are choosing PET Preform storage containers designed with high load capacity and stable layered structure.

HM Group's PET Preform Wire Mesh Container is built with mild steel and wire mesh sides for a loading capacity of 800 kg per container, without bending. This prevents stress marks and deformation on PET preforms stored at the base. The mesh size can be customized, and PP sheets can be added to create a smooth inner surface for small preforms. Wire diameter options allow cost control while maintaining strength and stability.

These lockable mild steel mesh containers can be stacked up to four layers, helping factories maximize vertical space without risking damage to the products. The foldable design also saves storage room when not in use. Each container is reusable for years, lowering long-term operational costs.

For blow-molding plants looking to reduce rejects, maintain neck-finish accuracy, and optimize warehouse layout, a high-load layered container system is one of the most effective solutions. Contact us for customization to match your preform size, weight, and production workflow.
