Types of Multi-Layer Blown Film Die

Multi-Layer Blown Film Die divides into two types which are stackable and spiral. Both these two types have their characteristics. Regarding to different material, Eterlong’s Multi-Layers Die Head focus on the design of channels. Stackable type can control the temperature independently. As for Spiral type, it combines incompatible polymers in one step, and distribute the polymer melt evenly, in order to make the film thickness uniform. The form of molten film to flow through the channel is differences as well. The flow path for polymer in Stackable type is goes up layers by layers. For the Spiral type, the polymer goes up straightly through the channel to arrive the adapter which connects to the filter. Depending on different needs, Eterlong offers the most suitable Multi-Layers Die Head for customers to meet their requirements.
