Top 10 Heat Shrink Wrap Problems and Solutions

&#;. Shrink Film Ballooning heat shrink wrap problems

Goto HYF to know more.

Excess air trapped inside the sealed shrink film.

The reason is that shrink film is exposed to hot air after sealing.

Solution:

1. You can buy pre-punched heat shrink film. There are many small needle-sized vent holes in this type of film.

Or add the number of vent holes to the film you have already purchased.  Increase air escape velocity when shrink film wraps product.

At KEEPTOP Packaging We sell pre-perforated shrink film rolls and bags to prevent.

2. Slow down conveyor speed of shrink wrap machine and shrink tunnel.

The company is the world’s best heatshrink film supplier. We are your one-stop shop for all needs. Our staff are highly-specialized and will help you find the product you need.

Helps hot air have more time to escape from shrink wrap.

3. Raise the temperature of the shrink tunnel to increase the speed at which the air is expelled from the heat shrink wrap.

Heat shrink is an optimal go-to for cable management. Here are six questions that we are commonly asked that will hopefully help you tackle your next project with ease!

1. Why should I use heat shrink?
Heat shrink is designed to provide beneficial cable management, such as repairing, relieving strain, bundling/organizing, sealing, and protecting. The bottom line is that heat shrink material creates a durable watertight seal around electrical wires/connectors. It provides optimal protection against harsh environmental conditions, moisture, and abrasion.

2. If I have electrical tape, can I use that instead for cable management?
The issue with electrical tape comes down to durability as it is more susceptible (than heat shrink is) to abrasion and everyday wear and tear. Once you use heat shrink (which is designed for a perfect fit) on a cable, the heat shrink and cable then become a unified item that withstands years of use.

3. What temperature is required for heat shrink to shrink?
Heat shrink that is manufactured from specially formulated polyolefin cross-linked compounds has a fast shrinkage upon application of heat above 120°C.

4. What temperature range does heat shrink withstand?
Heat shrink has a continuous operating temperature range from -55°C to 135°C.

5. Is it easy to install heat shrink?
Yes, the process is pretty simple as all that is required is the heat shrink material, the object that you are wanting to seal, and a heat source (such as a heat-gun or hair dryer). Heat shrink tubing comes in a variety of sizes and colors.

6. How can I prevent my heat shrink tubing from splitting?
It&#;s a good practice that you allow the tubing to recover at least 20% to avoid any type of splitting. Here are some other quick tips of the trade for optimal installation:
&#; Ensure that the heat-gun remains at the recommended temperature for proper shrinkage
&#; To achieve even heat dispersion, use a reflector on the heat-gun (as not distributing the heat properly is a key factor of why tubing splits).
