Sonoco Alcore


Which core is right for you?


All Sonotubes are spirally wound with recycled paperboard, and feature a visible spiral mark.

Sonotube Plus®

Sonotube Plus tubes feature a smooth surface, with one or two zippers, depending upon the form diameter. One or two vertical marks are visible.

Sonotube Premium

Sonotube Premium forms are coated on the inside with Duraglas technology, creating concrete columns with a very smooth, finish-free surface. These forms are available in a maximum length of 4 or 5 metres.

Sonotube Polygonal

Using high-density polystyrene, Sonotube Polygonal ensures perfect columns with smooth surfaces.

Supplemental Construction Products

We also offer a number of supplementary products for use with Sonotube forms, such as our shoring system, which is used to hold the form straight and secure during the construction process.

Our honeycomb board solution allows you to create concrete areas within foundations. Our board solution doesn’t stick to concrete, is reusable and be cut easily to meet your space requirements.

Sonoco Alcore’s concrete reservation box is used to make passage ways within concrete areas for wiring/access areas. With a thickness of 3.5mm, it’s lightweight, easy to modify on site, does not adhere to concrete and is 100% recyclable.

Case Studies

Our Products at Work

Hi-Radius Core

Our Hi-Radius core has a smooth, rounded edge on the unwinding end, which allows the producer to avoid using plastic caps. This solution is especially effective if our customer is spinning and texturizing the yarn in-house.
