Resins used to blowmould containers may differ in name and formulation, but they all have a few things in common. Material is expensive; the largest single cost incurred when producing a blowmoulded container is usually resin.
Costs in a Typical Container
In fact, the expense of the resin often exceeds all other operational costs combined. One truckload of resin can cost twenty to thirty thousand dollars depending on the material type.
Productivity is adversely affected when foreign substances are introduced to the resin handling system. Imperfections caused by contamination result in lost time and increased work because of the need for closer inspection.
A successful operation can not tolerate financial losses – and poor resin handling or excessive waste of materials can turn potential profits into major losses. To understand more about resin, let’s examine how it is used in an extrusion blowmoulding plant.
Virgin pellets arrive in one of three ways; by truckload, in cardboard boxes called ‘gaylords’, or by bulk tanker trucks or railroad hopper cars. When purchased and delivered by the ‘truckload’, forty thousand pounds of resin arrives at a facility and the material is transferred to an onsite silo.
Materials Arrives by Truckload and Transferred to Silo
If purchased by the ‘gaylord’, the resin arrives in one thousand pound cardboard boxes lined with plastic bags that are sealed by the resin manufacturer. The material is then integrated into the handling system using vacuum loaders.

Pellets can also be shipped in bulk tanker trucks or in railroad cars. When these arrive at the blowmoulding plant, the pellets are vacuumed into a storage silo that is part of the closed-loop resin handling system.
