Product features and attributes
Now that you've determined what kind of core you need, it's time to identify the features and attributes for that particular core.

Dimensional attributes
It's very important to know the dimensions of the core you need. Core dimensions are expressed in terms of:

• Length, expressed in inches or millimeters. Typically, core and tube length can be measured with a standard, certified tape measure. For lengths below five inches a standard tape measure does not have the accuracy required to measure increments of thousands of an inch.
  
  • Saw cut
    This primary cutting process is used for cores 30 inches or longer. The in-line process lowers production costs, but length tolerances are less stringent.
  • Blade cut
    This secondary process is used for cores 30 inches or less in length. It provides a smooth cut and offers more stringent length tolerances. Cores over 30 inches can also be blade cut.
    
• Inside diameter, expressed in inches or millimeters.Tube or core inside diameter is always measured in thousands of an inch. A tape measure or line gauge is not sufficient to record the roundness and diameter of a core or tube.
  
  Example: A three-inch nominal inside diameter is expressed as: 3.000", 3.010", 3.015", 3.025", etc. This exactness is critical in some winding and converting applications because the side of the spindle or mandrel that end users have differs between facilities, industries and markets.
  
  
  • Based on the end-user's mandrel or spindle size used in winding product onto tubes or cores.
  • Typically expressed in exact terms (to three decimal places) based on nominal diameter. (ex: A core with a three inch nominal diameter would have an inside diameter of 3.025 inches).
    
• Wall thickness, expressed in inches or millimeters.Core or tube wall thickness can be measured with a standard certified tape measure but it is advisable, if wall thickness is a critical specification, that it is measured in thousands of an inch.
  
  • Based on the desired flat strength needed.
  • Ex: A wall thickness of .500 (1/2-inch) would have a higher flat crush strength than a tube with a wall thickness of .375 (3/8-inch).

Special features
Our tubes and cores can be customized to meet your needs. Choose from any of the following options:

• Cutting and trimming
  • Tubes and cores can be cut to any length so you just remove them from their packaging and put them on your equipment.
• Printing and labeling
  • Tubes and cores can be printed in-house using up to three colors. Customize your tube or core with your company logo; color code cores by department or product or just create a special message to help you market your business.
• Special surfaces
  • Moisture resistant
    Let us coat your tubes with wax or other moisture-resistant options.
  • Friction control
    Using different paper combinations, we can engineer properties into cores that offer friction control and self-start adhesives.
  • Smooth surface
    The outside surface of the core can be made "seamless" to prevent spiral markings from imprinting on film, foils and pressure-sensitive materials.
• End caps
  • Choose end caps from metal, plastic or paper.
• Other terms
  • Delivery
    Depending on the quantities, cores and tubes can be shipped via UPS, customer pick-up, standard common carrier or a carrier of your choice. Less-than-truck load (LTL) quantities are shipped FOB. our facility and truck-load quantities are shipped freight allowed.
  • Lead time
    Our lead time ranges from 24 hours to five days depending on the product type and special attributes.
