Tyvek comes in many grades — and choosing the wrong one can affect everything from printability to the way your finished product feels in someone's hands. This guide breaks down the three most commonly specified grades for product manufacturers and designers, so you can make an informed decision before ordering samples.

The Three Grades at a Glance

At first glance, 1056D and 1443R look similar — both around 43–45 g/m², both classified as "soft structure." But they behave very differently in your hands and under a press. Here's why.

Understanding Tyvek's Structure Types

All DuPont Tyvek® is made from flash-spun HDPE filaments. But the way those filaments are bonded gives each grade its distinctive character.

The Key Differences You Need to Know

1073D vs 1056D: Same Structure, Different Weight

These two are closely related — both Type 10, both crisp and paper-like, both excellent for printing. The difference is purely weight:

• 1073D (75 gsm) feels more substantial — better for wallets, structured bags, and heavier packaging applications
• 1056D (43 gsm) is thinner and more flexible — ideal for wristbands, lightweight labels, and situations where bulk must be minimized

1056D vs 1443R: Same Weight, Completely Different Feel

Both are around 43–45 gsm, but they feel like completely different materials:

• 1056D is stiff and paper-like — it crinkles, crease, and feels like a thick piece of paper
• 1443R is soft and fabric-like — it drapes, bends smoothly, and feels much closer to a nonwoven textile
