Heat shrink is used in many jobs because it is simple and strong. The tubing starts as a loose plastic sleeve or film. You put it over the thing you want to cover. Then, you use a heat gun, like one that uses propane, to heat it up.
You heat the tubing to about 400-600°F.
The heat makes the polymer chains inside move and relax. They try to go back to their tangled shape.
The tubing shrinks in every direction at the same time. This is called biaxial shrink. It squeezes tightly around your item and makes a strong seal.
This makes heat shrink wrap and tubing helpful for many things. It gives a tight layer that blocks dust, water, and other dangers. It also helps your packaging or wires last longer.
Heat shrink is used for many things. In packaging, it is often wrapped over boxes, cartons, and cans. It keeps products clean and stops people from opening them.

Now you are ready to apply heat shrink tubing. ECOPACK makes this easy with user-friendly products. You can use these steps for diy projects or for large shipments. Here is how you do it:
Place your items on a strong pallet. Stack boxes or goods evenly. Do not let anything hang over the edge. Use corner boards if you have fragile edges.
Pick the right heat shrink wrap or heat shrink tape. Drape it over the load. Make sure it covers all sides and reaches below the top deck of the pallet.
Use a heat gun to start shrinking. Begin at the base of the load. Move the heat gun slowly around the bottom, then up the corners, and finally the flat sides. Keep the heat gun moving to avoid overheating one spot.
Rotate the heat gun as you work. This helps the heat shrink tape shrink evenly. Uneven heating can cause weak spots or leaks.
Let the load cool for one to two minutes. Do not move it right away. After cooling, do a "Tug Test" to check if the wrap is anchored well.
Inspect your work. Look for gaps or loose spots. If you find any, use the heat gun again for quick repairs.
To prevent air bubbles or "bird-caging," start heating from the center of the tube and move toward the ends. This pushes the air out as the material contracts.
You can use heat shrink tape for diy projects, quick repairs, or large shipments. Always use a heat gun for the best results. If you use the wrong tool, you may not get a secure fit.
