TECHNICAL SPECIFICATION

Spiral cardboard tubes are a common everyday item. How often do we finish a roll and dispose of the tube? Yes, inevitably, the recycling bin is the ultimate destination for cardboard tubes. For this reason, it is important that they are designed and manufactured optimally for their intended task. If they are too resistant, they represent ‘over-quality’ and therefore excessive expenses. If they are not resistant enough, they will cause winding problems or worse, complaints from your customers.

Cores are characterized by their crush resistance and dimensional precision. To ensure the optimal construction of the cores you use, we first ensure the supply of diversified cardboard grades that meet the various criteria demanded by our customers. The multiple applications to which all the spiral tubes we manufacture are destined require numerous grades of cardboard. The vagaries of the cardboard market being what they are, sourcing from various producers allows us to obtain more competitive prices that are reflected in the price of your tubes.

Finally, to exactly meet the quality criteria you are looking for, we have measuring devices that allow us to effectively control the formats and resistances required by our customers throughout the spiral tube production process.

As previously mentioned, spiral tubes are characterized by their dimensional precision and crush resistance (flat crush). They are available in a wide range of sizes, thicknesses, and lengths.

The tube specifications include:

  • Inner diameter
  • Thickness
  • Length
  • Type of paper or finishing cardboard
  • Crush resistance
  • External printing
  • Hydrophobicity

 

Available sizes are:

  • From 0.625” to 12” diameter
  • From 0.040” to 0.550” thickness
  • From 2” to 250” length
