What is the Thickness of Paper Core (paper tube)?
Thick paper cores, also known as paper tubes or industrial paper cores, are produced from carton paper - a familiar type of paper in the field of goods packaging. Paper cores and thick paper tubes can be considered part of the packaging group, but they are not used to wrap the product from the outside but are only used to fix and shape the product from the inside.

In case the paper core has a large diameter, it can be used to wrap the product. This is also a way for thick paper cores to become unique and extremely convenient round cartons.

Thick paper core meets the criteria of hardness, durability, bearing capacity... Customers can choose the length, diameter, and hardness of the paper core as required.

Standards of Thick Paper Cores
External inspection:

No torn edges.
No scratches.
No swelling.
Does not smudge other colors.
No more glue or kaolin.
Pack:

Stick the core specification label (on each core).
Grind the edge and excess paper of the core.
Technique:

Correct size and required hardness.
The two ends of the core are not separated.
The hardness of the thick paper core will vary depending on the product. If the product has high wrapping and tightness, the hardness of the paper core must be stable and compatible. If the paper core is too thin or the hardness is not consistent with the tightening force, the paper core will be distorted and even damaged.

This prevents the product from sticking to the paper core, affecting the quality of the product. At this time, businesses will spend a lot of time and spend more money to invest in quality paper cores to overcome this problem.

In addition, substandard paper cores also affect the reputation of the product and the business. Therefore, the hardness of the paper core is an important factor contributing to the value of a business's products.

Application of Heavy Duty Paper Core for Rolling Industrial Steel Sheets at Steel Plants
Normally, steel corrugated iron rolls over 4 inches thick can stand on their own without needing a paper core fixed inside. However, thin steel corrugated iron products under 3 zem (color-coated corrugated iron, zinc/nickel plated...) must have a paper core inside to stabilize and help prevent the steel sheet from collapsing or denting.

- Advantages of using thick paper cores for steel corrugated iron rolls:

Paper core is many times lighter than iron core: reduces the weight of steel corrugated iron rolls - convenient and saves transportation costs (especially in export).
The paper core limits the loss of the innermost layer of the steel roll when removed from the winding roller.
The thick paper core does a good job of fixing and protecting the steel roll.
