How Long Can You Safely Store PET Preforms in PET Preform Storage Containers?

PET preforms are the starting point for most plastic bottles. However, they have one major weakness: they act like a sponge. In technical terms, PET is hygroscopic, meaning it absorbs moisture directly from the air.

The Risk of "Wet Preforms"

If preforms sit in a damp warehouse for too long, they become "wet." When you try to heat and blow these preforms into bottles, the moisture can cause bubbles or cracks. In high-humidity areas, research shows that quality can start to drop after just 3 to 6 months.

Why Our PET Preform storage containers Are the Better Choice

Many companies use cardboard boxes, but these can trap damp air inside and even get soggy themselves. Our wire storage containers are built to solve this problem while keeping your warehouse organized.

Key Features for Better Storage:

Maximum Ventilation: The open wire design allows air to flow freely. This prevents moisture from getting trapped around your preforms.

Rust Protection: Our containers are made of galvanized steel. This means they won't rust or degrade, even in humid environments.

Stackable Design: You can safely stack our cages 3 to 5 units high. This saves floor space while keeping the preforms off the damp ground.

Easy Visibility: You can see exactly what is inside each container. This helps you use older stock first (FIFO) so nothing sits for too long.

By using our ventilated metal mesh storage containers and keeping your storage area dry, you can ensure your preforms stay in good condition for the blow molding process.
