paper and plastic cores for thermal paper roll

The core is a necessary part during production of thermal paper rolls. There are several types of cores used in paper rolls. Basically, they are divided into 2 types according to the material. They are paper cores and plastic cores.

1. Paper core

Paper cores are produced through rolling paper material with glue. They can roll into different sizes. The inner core diameter for thermal paper roll is 13mm, 16mm and 25mm. The thickness of a core is usually at least 3mm to make it strong. Thus the popular sizes are 13x19mm, 16x24mm, 25x34mm.

2. Plastic core

Plastic core is produced within mould. Unlike the paper core, they can not be rolled into different thickness. Their sizes are normally fixed.

Two types of plastic cores are used for thermal paper rolls. One is plastic solid core. The other is honeycomb core.

13x17mm plastic solid core

13x22mm honeycomb core

Plastic cores can be in different colors like white, black, yellow, green, blue, etc.

Last not the least, with the development of technology, cores can be eliminated both for production and usage. Coreless thermal paper rolls are now on the trend. It decreases the production cost and save space for merchant.

    It’s great that you elaborated on how paper cores differ from plastic cores in the sense that paper cores can be rolled to different sizes whereas the sizes of the plastic ones are fixed. I’ve always wondered how paper rolls take their shape and how the cores got to where they are in the first place. I wonder if these cores are manufactured by manufactures or bought from a different vendor. Any thoughts?

    The Plastic cores can be extruded then cut to length size or can be injection molded to size
