Many of our clients have a specialized interest in the materials we use to manufacture our flexible packaging products. A good example of this is the film and tubing that we use for our roll stock and polyurethane bags. The Urethane Primer provided below explains our manufacturing processes and the properties that make polyurethane such an effective packaging material.<\/p>\n\n\n\n
Thermoplastic polyurethane (TPU) was discovered in the late 1930s as part of Germany’s World War II research. It is a thermoplastic elastomer (TPE), which combines the mechanical and physical properties of rubber with the advantages of thermoplasticity and processability. Other examples of TPEs include polyethylene and polypropylene.<\/p>\n\n\n\n
Noted for its high performance and general overall toughness, urethane rapidly became the material of choice for a wide range of critical and “can’t fail” applications. Urethane’s unique characteristics make it an extremely versatile material that outperforms many other thermoplastics. For example, it retains its flexibility even at low temperatures, where polyvinyl chloride (PVC) becomes brittle.<\/p>\n\n\n\n
