What is Cord Strap?
Many companies have created such outstanding products that their brand name became a standard name for their industry. Brands like Band-Aid, Q-tips, and Scotch Tape are registered trademarks made by Johnson and Johnson, Unilever, and 3M. These brands have been turned into what is called a generalized trademark (a generic description), that stands for a particular quality of a product or service.
Cordstrap, like Band-Aid, Q-tips and Scotch Take has become a generalized trademark that stands for superior quality, service and innovation. Cordstrap® is a registered trademark and is NOT synonymous with just any polyester strap. Since the registered trademarks, Cordstrap® and Cordlash® can not be used by other manufacturers of synthetic strapping, Cord Strap, Cordstrapping and Cord Strapping are now used extensively as generic terms by many manufacturers and distributors of the following non metallic strapping types:
Composite Corded Polyester Strapping
Bonded Corded Polyester Strapping
Woven Polyester Strapping
Other terms that are commonly used to refer to the 3 above mentioned types of strapping are:
Polyester Strapping
Fabric Strap
Plastic Strap
Corded Polyester Strapping
Nylon Strapping
How does Cord Strap work?
Cord Strap is joined together using a metal wire buckle. This buckle is used with any of the above mentioned type of straps. This type of joint creates a high efficiency and provides an increased overall strength in the system use of the strapping. However, the overall system strength varies greatly between manufacturers, depending on the quality, design and finish of the buckles used. Some manufacturers promote the use of other joints like flat metal seals. Since this by definition results in lower and inconsistent joint efficiencies, Cordstrap will only advise the use of the correct type of steel wire buckles.
The history of Cord Strap
Cord Strap, or Cordstrapping, was developed in the 1960’s as an alternative to steel strapping for industrial strapping applications. It was created by our founder, Fred van Eck, who came up with the name Cordstrap for both the product and the company.
Where is Cord Strap made from?
Cord Strap was originally made from rayon. Rayon was commonly used as reinforcement in motor vehicle tires. Our founder came up with the idea to use the rayon yarn, at that time in abundance, as the first real alternative to steel banding. In the early 70’s polyester yarn became available. It started to take the place of rayon because of its higher strength and weather-resistant properties. This resulted in the switch to industrial high tenacity polyester filament yarn. The first polyester Cord Strap was a bonded strapping. Bonded cordstrap is made of a series of yarns, laid longitudinally alongside each other bonded with glue.
These days, all forms of Cord Strap - composite corded polyester strapping, bonded corded polyester strapping and woven polyester strapping - are made for the most part from high tenacity industrial polyester yarns. The yarns are bonded together with a bonding agent. In those days the bonding agent commonly used was cold glue. Today we use Hot Melt glue or polymer coating. These bonding agents offer the advantage of not deteriorating in wet and adverse weather conditions (as cold glue does).
Why Poly Propylene Strap is NOT the same as Cord Strap
Please be aware that although it looks exactly the same, some Cord Strap is made from polypropylene as if it is made of polyester. However, the elongation properties of poly propylene based strap are completely different from polyester Cord Strap. A simple trick to compare is to take a small sample of the strap and place it in water. Polyester strapping will sink and poly propylene strapping will float.
For which cargo securing applications can you use Cord Strap?
Cord Strap, or Cordstrapping, is available in different strengths, ranging from 1,000 lbs (450 daN) to in excess of 45,000 lbs (20,000 daN). It is known to be the safer, stronger, easier to use and cost effective alternative to almost all applications where steel strapping is currently being used.
Cord Strap can be used to strap and/or secure cargo in:
a.) any industry
b.) any application
c.) any mode of transport
Cord Strap, or cordstrapping, can be used for following applications:
a.) Bundling
b.) Palletizing
c.) Unitizing
d.) Containerization
e.) Intermodal Loads
f.) Reinforcing
g.) Carton/Crate Closing
h.) Deck Lashings
i.) Railcar Loading
Please visit our industries and/or applications pages to see how to use Cord Strap, or Cordstrapping, in your industry or application. In both sections you will find multiple images demonstrating a wide variety of strapping applications.
What are the properties of Cord Strap?
The following table is an excerpt of the ASTM D4675 Standard Guide for Selection and Use of Flat Strapping Materials and compares the properties of the various strapping materials available to you.
The table clearly shows that Cord Strap outperforms other strapping types available on most properties.
